Chronotype in bipolar disorder: Differences in sleep quality, social jet lag, physical activity, and diet / Cronotipo en trastorno bipolar: Diferencias en la calidad de sueño, jet lag social, actividad física y dieta

Abstract Introduction People with bipolar disorder are at a higher risk of metabolic morbidity and mortality. Chronotype may play a significant role due to its effect on sleep quality, eating patterns, and physical activity. Objective To compare sleep quality, social jetlag, physical activity, and diet, depending on the chronotype of people with bipolar disorder, and to determine the association between these variables. Method Cross-sectional, comparative, correlational study. The sociodemographic and clinical characteristics of subjects were assessed. Chronotype was determined using the Composite Scale of Morningness while sleep quality was evaluated through the Pittsburg Sleep Quality Index. Social jet lag was calculated through the absolute difference between the midpoint of sleep on weekends and workdays. Physical activity was measured through the Bouchard Activity Record and diet was evaluated through a food frequency questionnaire. Comparative analyses were performed between chronotype categories and the association between variables was measured. Results 116 subjects were included. Subjects with evening chronotype reported poorer sleep quality than those with morning chronotype. Eveningness was associated with lower sleep quality scores and more hours of sleep on workdays, as well as with higher consumption of cold meats, calories, and sodium. Trends indicate greater social jet lag and low physical activity levels among evening chronotypes. Discussion and conclusion The effects of chronotype on study variables require further research to clarify this complex relationship and develop educational strategies to promote sleep hygiene, physical activity, and a healthy diet.

Resumen Introducción Las personas con trastorno bipolar corren mayor riesgo de presentar morbimortalidad metabólica. El cronotipo podría desempeñar un rol importante por su efecto sobre la calidad de sueño, los patrones de alimentación y la actividad física. Objetivo Comparar la calidad de sueño, el jet lag social, la actividad física y la dieta en función del cronotipo de personas con trastorno bipolar, así como determinar la asociación entre estas variables. Método Estudio transversal, comparativo y correlacional. Se evaluaron las características sociodemográficas y los antecedentes clínicos de los participantes. El cronotipo se determinó con la Escala Compuesta de Matutinidad y la calidad de sueño con el Índice de Calidad de Sueño Pittsburg. El jet lag social se calculó como la diferencia absoluta entre el punto medio de sueño en días libres y de trabajo. La actividad física se midió con el registro de Bouchard y la dieta con un cuestionario de frecuencia de consumo de alimentos. Se realizaron análisis comparativos entre categorías de cronotipo y se evaluó la asociación entre variables. Resultados Se incluyeron 116 participantes. Las personas de cronotipo vespertino reportaron menor calidad de sueño en comparación con las del cronotipo matutino. La vespertinidad se asoció a puntuaciones de menor calidad de sueño y más horas para dormir en días de trabajo, así como a mayor consumo de embutidos, calorías y sodio. Las tendencias indican mayor jet lag social y bajo nivel de actividad física entre cronotipos vespertinos. Discusión y conclusión Los efectos del cronotipo sobre las variables de estudio requieren más investigación, que aclare esta compleja relación, para desarrollar estrategias educativas de higiene de sueño, actividad física y dieta saludable.

Mental health problems among healthcare workers involved with the COVID-19 outbreak

Objective: The mental health problems and perceived needs of healthcare workers involved with coronavirus disease (COVID-19) may vary due to individual and contextual characteristics. The objective of this study was to evaluate healthcare workers' mental health problems during the common COVID-19 exposure scenario in Mexico, comparing those on the frontline with other healthcare workers according to gender and profession, determining the main risk factors for the most frequent mental health problems. Methods: A cross-sectional online study was conducted with a non-probabilistic sample of 5,938 Mexican healthcare workers who completed brief screening measures of mental health problems and ad hoc questions about sociodemographic professional characteristics, conditions related to increased risk of COVID-19 infection, life stressors during the COVID-19 emergency, and perceived need to cope with COVID-19. Results: The identified mental health problems were insomnia, depression, and posttraumatic stress disorder (PTSD), all of which were more frequent in frontline healthcare workers (52.1, 37.7, and 37.5%, respectively) and women (47.1, 33.0 %, and 16.3%, respectively). A lack of rest time was the main risk factor for insomnia (OR = 3.1, 95%CI 2.6-3.7, p ≤ 0.0001). Mourning the death of friends or loved ones due to COVID-19 was the main risk factor for depression (OR = 2.2, 95%CI 1.8-2.7, p ≤ 0.0001), and personal COVID-19 status was the main risk factor for PTSD (OR = 2.2, 95%CI 1.7-2.9, p ≤ 0.0001). Conclusion: The most frequent mental health problems during the common exposure scenario for COVID-19 in Mexico included the short-term psychological consequences of intense adversity. A comprehensive strategy for preventing mental health problems should focus on individuals with cumulative vulnerability and specific risk factors.

A qualitative assessment of psycho-educational videos for frontline COVID-19 healthcare workers in Mexico / Evaluación cualitativa de videos psicoeducativos para personal de salud de primera línea ante el COVID-19 en México

Abstract Introduction Frontline COVID-19 healthcare workers (FLHCWs) are at a high-risk of suffering occupational stress- and trauma-related mental health problems, including burnout and compassion fatigue (B&CF). Given the time limitations (due to their heavy workloads) and need to minimize face-to-face interventions (in order to avoid contagions), psychological interventions for FHCWs should be as brief and remote as possible. Objective To evaluate the usability and clarity of evidence-based psycho-educational videos to prevent B&CF, to deal with uncooperative, hostile, and anxious patients and relatives, and to use personal protective equipment (PPE), from the perspective of Mexican FLHCWs. Method Based on a convenience sampling by intensity approach, videos were distributed requesting feedback based on specific questions through WhatsApp to FLHCWs. Field notes were used to triangulate the information. Results Content analysis of feedback from a final sample of 24 participants ‒75% women, 42 ± 8.4 years old‒ yielded three general thematic categories and seven subthemes: 1. content evaluation, which included three subthemes: utility, pertinence, and practicality; 2. dissemination and other needs, with two subcategories: willingness to share and receive more videos (other needs); and 3. format aspects, also comprising two subthemes: attractiveness and duration. All participants found the videos content very beneficial, relevant, and applicable to the workplace and even in their everyday personal and family life, and were willing to share them and to receive more videos on other issues, including strategies to manage problems related to isolation. Discussion and conclusion Escalation of this remote preventive intervention to other COVID-19 centers and future similar epidemics is recommended.

Resumen Introducción Los trabajadores de la salud de primera línea (TSPL) ante el COVID-19 presentan alto riesgo de desgaste profesional y fatiga por compasión (DP&FC). Tomando en cuenta sus limitaciones de tiempo y la necesidad de minimizar las intervenciones cara a cara, las intervenciones psicológicas para los TSPL deben ser tan breves y remotas como sea posible. Objetivo Evaluar la utilidad y claridad de videos psicoeducativos basados en evidencia para prevenir DP&FC, el manejo de pacientes y familiares no cooperativos, hostiles o ansiosos, y el uso de equipo de protección personal desde la perspectiva de los TSPL mexicanos. Método Los videos se distribuyeron a los TSPL por medio de WhatsApp, solicitándoles su opinión con base en preguntas específicas. Se utilizaron notas de campo para triangular esta información. Resultados El análisis de contenido de las retroalimentaciones recibidas por una muestra final de 24 participantes ‒75% mujeres, 42 ± 8.4 años‒ arrojó tres categorías temáticas y nueve subtemas: 1. evaluación de contenido, con tres subtemas: utilidad, pertinencia y practicidad, 2. difusión y otras necesidades, con dos subcategorías: disponibilidad tanto a compartir como a recibir más videos (otras necesidades), y 3. aspectos de forma, también con dos subtemas: atractivo y duración. La totalidad consideró los videos muy benéficos, relevantes y aplicables en el trabajo y su vida diaria personal y familiar; y reportó disposición a compartirlos y a recibir más material de este tipo. Discusión y conclusión Se recomienda el escalamiento de esta medida preventiva y remota a otros centros COVID-19 y en futuras epidemias similares.

Self-perceived health in psychiatrists and psychiatry trainees. The role of perfectionism and distress / Autopercepción de la salud en psiquiatras y residentes de psiquiatría. El rol del perfeccionismo y el distrés

Abstract Introduction Self-perceived health (SPH) is related to disease and well-being. Psychiatrists report burnout and mental disorders more frequently than other physicians, while personality traits related to perfectionism may influence the perception of well-being and health in these professionals. Objective To compare and determine the association between demographic variables, health conditions, perceived distress, perfectionism, and SPH. Method A cross-sectional, retrospective, comparative study was performed through an online survey. Psychiatrists and psychiatry trainees who were willing and able to participate were included. Demographic variables and self-reports of mental and physical conditions were examined. SPH was rated on a 10-point visual analogue scale and perfectionism through the Multidimensional Perfectionism Scale. Comparative analyses and multiple linear regression models were performed. Results Three hundred and thirty psychiatry trainees and 355 psychiatrists were recruited. Psychiatrists reported more physical conditions (32.4% vs. 15%, p < .001), distress (p < .001), and perfectionism (p < .001). Major depression and anxiety were present over 50% of all participants. A higher SPH was associated with being partnered and having higher distress levels in psychiatry trainees and with the absence of a physical health condition, less concern over errors, and higher personal standards in psychiatrists. Discussion and conclusion Self-oriented perfectionism may have a significant motivational component, accentuated by competitiveness and individualism. Being married and having higher levels of distress in psychiatry trainees appears to create a sense of satisfaction with achievements. The implementation of strategies to prioritize and meet goals is necessary to have an adequate work-life balance without affecting personal satisfaction or the sense of achievement.

Resumen Introducción La autopercepción de la salud (APS) se relaciona con enfermedad y bienestar. Los psiquiatras reportan desgaste emocional y trastornos mentales con mayor frecuencia que otros médicos. El perfeccionismo puede influir en la percepción de la salud en estos profesionistas. Objetivo Comparar y determinar la asociación de variables demográficas, condiciones de salud, distrés y perfeccionismo con la APS. Método Se realizó un estudio transversal, retrospectivo y comparativo mediante una encuesta en línea. Se incluyeron psiquiatras y residentes de psiquiatría que participaron voluntariamente. Se registraron variables demográficas, enfermedades médicas y psiquiátricas (autorreporte). La APS se evaluó con una escala análogo-visual de 10 puntos y el perfeccionismo con la Escala Multidimensional de Perfeccionismo. Se realizaron análisis comparativos y modelos de regresión lineal múltiple. Resultados Se reclutaron 330 residentes y 355 psiquiatras. Los psiquiatras reportaron más enfermedades físicas (32.4% vs. 15%, p < .001), distrés (p < .001) y perfeccionismo (p < .001). Más del 50% de los participantes reportaron ansiedad y depresión. Una mayor APS se asoció con tener pareja y mayor distrés en los residentes, y con la ausencia de una enfermedad física, menor preocupación por errores y mayores estándares personales en los psiquiatras. Discusión y conclusión El perfeccionismo orientado hacía sí mismo puede tener un componente motivacional acentuado por la competitividad y el individualismo. Tener una pareja y presentar mayor distrés en los residentes pudiera crear una sensación de satisfacción por logros. La creación de estrategias para priorizar y alcanzar objetivos es necesaria para tener un equilibrio de vida sin afectar la satisfacción personal y la sensación de logro.

Development of the Mexican Version of the Empathy Quotient / Desarrollo de la versión mexicana del Cuestionario de Empatía

Abstract Introduction Empathy is defined as the ability or process to identify and understand other person's situation, feelings, and motives. These responses are essential for relationships and social behavior. Baron-Cohen et al. created the Empathy Quotient (EQ), a scale explicitly designed to have a clinical application. The instrument evaluates three constructs of empathy and several studies around worldwide, but not in Mexico. Objective To examine the psychometric properties and the factor congruence of the EQ in a community sample from Mexico City. Method Cronbach´s alpha coefficient and a correspondence factorial analysis was performed to test the relation between response options and factors from the Exploratory Factor Analysis 200 adults without Axis I disorders through the MINI, filled out the Spanish version of the short version (28-items) of the EQ. An exploratory factor analysis was performed while reliability was tested with Cronbach's alpha. In addition, correspondence factorial analysis and the factor congruence coefficient were determined. Results Five items were eliminated from the original 28-item EQ. From the 23 remaining items, only 16 were grouped in the three original proposed dimensions (cognitive empathy: 8 items, emotional reactivity: 4 items and social skills: 3 items), while one item showed communality with a different domain from the one originally proposed. Reliability was adequate (.82) as well as the congruence coefficients (.76 to .99). Discussion and conclusion The EQ Mexican 16-item version is a good tool to assess empathy in a Mexican population.

Resumen Introducción La empatía es definida como la capacidad para identificar y comprender las situaciones, sentimientos y motivaciones de otra persona. Estas respuestas son esenciales para relaciones y comportamientos sociales. Baron-Cohen et al. crearon el cociente de empatía (EQ), una escala diseñada para tener aplicación clínica. El instrumento evalúa tres constructos de empatía y ha probado sus propiedades psicométricas con resultados adecuados en varios estudios mundiales, pero no en México. Objetivo El propósito de este estudio fue examinar las propiedades psicométricas y la congruencia factorial del EQ en una muestra mexicana. Método El alpha de Cronbach y el análisis factorial fueron aplicados para probar la relación entre las opciones de respuesta y los factores en 200 adultos sin diagnóstico, a través de la entrevista MINI. Se utilizó la versión corta en español del EQ y se realizó un análisis factorial exploratorio dónde se probó la confiabilidad con el alfa de Cronbach y se determinó adecuada correspondencia y congruencia factorial. Resultados Se eliminaron cinco reactivos de la escala original de 28 reactivos. De los 23 reactivos restantes, solo 16 se agruparon en las tres dimensiones originales (empatía cognitiva: 8 reactivos, reactividad emocional: 4 reactivos y habilidades sociales: 3 reactivos) mientras que un reactivo mostró una comunalidad con un dominio diferente del original. La confiabilidad fue (.82), así como los coeficientes de congruencia (.76 a .99). Discusión y conclusión La versión del EQ es una buena herramienta para evaluar la empatía en población mexicana.

Psychological distress among transgender people in Brazil: frequency, intensity and social causation - an ICD-11 field study

Objective: To describe self-reported experiences of gender incongruence related to discomfort and body changes to be more congruent to the desired gender, and to examine whether experiences of psychological distress related to gender identity were more strongly related to the experience of gender incongruence per se or to experiences of social rejection. Methods: This field study used a structured interview design in a purposive sample of transgender adults (aged >18 years or older) receiving health-care services in two main reference centers in Brazil. Results: A high proportion of participants (90.3%, n=93) reported experiencing psychological distress related to their gender identity and report having experienced social rejection related to their gender identity during the interview index period and that rejection by friends was the only significant predictor for psychological distress. Conclusions: Gender incongruence variables were not significant predictors of distress. This result supports the recent changes proposed by the Word Health Organization in ICD-11 to move transgender conditions from the Mental and Behavioral Disorders chapter to a new chapter on Sexual Disorders and Conditions Related to Sexual Health.

Stigma and perceived aggression towards schizophrenia in female students of medicine and psychology / Estigma y percepción de agresión hacia la esquizofrenia en mujeres estudiantes de medicina y psicología

Abstract Introduction The main attitudes towards people with schizophrenia are fear and rejection, which derive from the idea that patients have no control over their behavior and that they are aggressive, violent, and/or dangerous. Several studies have shown that mental health professionals show negative attitudes towards patients with schizophrenia from the start of their professional training. Objective To compare the stigmatizing attitudes and perception of aggression of female undergraduate students of medicine and psychology towards people with schizophrenia. Method Fifty-seven (49.6%) undergraduate medical students and 58 (50.4%) psychology students in the early semesters of their professional training were included. Both groups answered the Opinion Scale on Mental Illness and the Public Concept of Aggressiveness Questionnaire (PCA). Results Over 60% of the students from both degree courses considered that the individual with schizophrenia described in the vignette could be aggressive, with a higher percentage corresponding to female students enrolled in the medical degree program. In this group, more negative attitudes towards the disease were observed in terms of separatism, restriction, and stigmatization. Discussion and conclusion It is essential to promote clear, objective information with a biopsychosocial approach to the disease in the syllabus in order to reduce or eliminate stigmatizing beliefs and attitudes regarding schizophrenia acquired prior to professional training.

Resumen Introducción Las principales actitudes hacia las personas con esquizofrenia son de temor y rechazo, las cuales surgen de la idea de que los pacientes no tienen control sobre su comportamiento y que son agresivos, violentos y/o peligrosos. Diversos estudios han señalado que los profesionales de la salud mental muestran actitudes negativas hacia los pacientes con esquizofrenia desde el inicio de su formación profesional. Objetivo Comparar las actitudes estigmatizadoras y la percepción de agresión de mujeres estudiantes de pregrado de medicina y de psicología hacia las personas con esquizofrenia. Método Se incluyeron 57 (49.6%) estudiantes de pregrado de medicina y 58 (50.4%) de psicología que cursaban los primeros semestres de su formación profesional. Ambos grupos contestaron la Escala de Opiniones sobre la Enfermedad Mental y el Cuestionario de Concepto Público de Agresividad (CPA). Resultados Más del 60% de las estudiantes de ambas carreras consideraron que el sujeto con esquizofrenia descrito en la viñeta podría ser agresivo. De éstas, el mayor porcentaje de alumnas pertenecía a la carrera de medicina. De forma similar, en este grupo se observaron mayores actitudes negativas hacia la enfermedad en términos de separatismo, restricción y estigmatización. Discusión y conclusión Es necesario promover dentro del currículo académico información clara y objetiva con un enfoque biopsicosocial de la enfermedad con la finalidad de reducir o eliminar las creencias y actitudes estigmatizadoras sobre la esquizofrenia adquiridas antes de la formación profesional.

Mental health literacy about bipolar disorder and schizophrenia among medical students: a comparative study of illness recognition, treatment, and attitudes according to perception of aggressiveness-dangerousness / Alfabetización en salud mental sobre el trastorno bipolar y la esquizofrenia en estudiantes de medicina: estudio comparativo del reconocimiento de la enfermedad, tratamiento y actitudes de acuerdo a la percepción de agresión-peligrosidad

Abstract Introduction Lack of information may result in health professionals' negative attitudes toward individuals with mental illness. Objective We sought to determine the association between the perception of aggressiveness-dangerousness and illness recognition, suggested treatment, and attitudes regarding schizophrenia and bipolar disorder in a group of medical students. Method This field study used a non-experimental, cross-sectional comparative design in a purposive sample of medical students. Mental illness recognition, beliefs about adequate treatment, perception of patient's aggressiveness-dangerousness, and attitudes toward severe mentally ill persons were assessed with previously validated instruments. Results Of the 104 participants, 54.8% identified a mental health condition in the schizophrenia vignette compared with only 3.8% in the case of bipolar disorder. Most students believed that both diagnoses could lead to aggressive behaviors. Dangerousness was more frequently perceived in the schizophrenia vignette. Discussion and conclusion It is necessary to sensitize and educate medical students so they have accurate information about symptoms and available treatments for individuals with mental illnesses.

Resumen Introducción La falta de información puede dar como resultado actitudes negativas de los profesionales de la salud hacia los individuos con trastornos mentales. Objetivo Determinar la asociación entre la percepción de agresión-peligrosidad y el reconocimiento de la enfermedad, tratamiento sugerido y actitudes sobre la esquizofrenia y el trastorno bipolar en un grupo de estudiantes de pregrado de medicina. Método El presente es un estudio no experimental, transversal comparativo en una muestra propositiva de estudiantes de medicina. El reconocimiento de la enfermedad, creencias acerca del tratamiento más adecuado, percepción de la agresión-peligrosidad del paciente y las actitudes hacia los trastornos mentales graves fueron evaluados con instrumentos previamente validados. Resultados El 54.8% de un total de 104 participantes identificaron un estado de salud mental en la viñeta de esquizofrenia en contraste con tan sólo el 3.8% para el caso de trastorno bipolar. La mayoría de los estudiantes consideraron que ambos diagnósticos se relacionaban con conductas agresivas. La peligrosidad fue percibida más frecuentemente en la viñeta del caso con esquizofrenia. Discusión y conclusión Es necesario sensibilizar y educar a los estudiantes de medicina para que tengan información clara y precisa sobre los síntomas y tratamientos disponibles para los individuos con trastornos mentales.

Evaluación psicológica de la agresividad impulsiva/predeterminada y factores asociados: Un estudio transversal en usuarios de los servicios de salud en Tabasco, México / Psychological evaluation of impulsive/premeditated aggression and associated factors: a cross-sectional study in users of health services in Tabasco, Mexico

Resumen: INTRODUCCIÓN: La conducta suicida es un problema de salud pública. Se sugiere que la personalidad impulsiva o predeterminada participa en los actos de agresividad como el suicidio. OBJETIVO: En este estudio se identificaron diferencias sociodemográficas, de intento de suicidio y la presencia de depresión entre individuos con característica de agresividad impulsiva o predeterminada. MÉTODOS: Se realizó un estudio de tipo transversal que incluyó a 200 residentes de Villahermosa, Tab., México, usuarios de los servicios de salud en ese Estado. La agresividad predeterminada o impulsiva se caracterizó usando la Escala de Agresión Impulsiva/Predeterminada (IPAS). Las características sociodemográficas, de intento de suicidio y de depresión fueron divididas de acuerdo al tipo de agresividad. Subsecuentemente fueron comparadas las características entre los dos grupos. RESULTADOS: Los resultados psicológicos revelaron que la agresividad impulsiva está presente en 62.71 % de la población. Estar desempleado y ser mujer fueron asociadas con la agresividad predeterminada. De igual forma, la mayor proporción de personas con depresión se observó en el grupo de personas predeterminadas (x2 = 18.29, gl = 1, p = 0.001). La proporción de personas con por lo menos un intento de suicidio a lo largo de la vida es similar en las impulsivas y las predeterminadas (6.06% y 6.30%, respectivamente). DISCUSIÓN Y CONCLUSIÓN: El presente estudio no muestra relación entre la personalidad y la proporción del intento de suicidio en los usuarios de los servicios de salud en Tabasco. Sin embargo, el estado de ánimo podría estar asociado con la toma de decisiones.

Abstract: INTRODUCTION: Suicidal behaviour is a public health problem. It has been suggested that impulsive or premeditated personality interferes with aggressive acts such as suicide. OBJECTIVE: In this study, we identified the socio-demographic differences when attempting suicide, as well as the concomitant depression among individuals characterized by impulsive or premeditated aggression. METHODS: We performed a transversal study that included 200 residents of Villahermosa, Tabasco, Mexico, who regularly use the city's General Health Services. The premeditated or impulsive aggression was evaluated using the Impulsive/Premeditated Aggression scale (IPAS). The sample was divided in two groups: impulsive and premeditator individuals. Suicidal attempt, presence of depression and socio-demographic characteristics were evaluated after wards and compared between groups. RESULTS: The psychological evaluation revealed that impulsive aggression is present in 62.71% of the population. We observed that being unemployed and/or being a woman were characteristics associated with premeditated aggression. The premeditators group had the higher proportion of concomitant depression (x2 = 18.29, gl = 1, p = 0.001). The proportion of people that had attempted suicide at least once during their lives was similar in both groups (impulsive = 6.06%, premeditators = 6.30%). DISCUSSION AND CONCLUSION: This study does not show any association between the personality (impulsive or premeditative) and the frequency of suicide attempts in the Tabascan General Health Services users. Nevertheless, the frame of mind (depression) could be associated with taking decisions when attempting suicide.

Estudio de traducción y validez del Sistema de Codificación Etológica para Entrevistas ECSI (Ethological Coding System for Interviews) / Study of the application and validation of the Ethological Coding System for Interviews (ECSI)

Antecedentes El diagnóstico psicoterapéutico se fundamenta en exploraciones verbales y/o pruebas psicológicas. En contraste, a menudo se descuida la relevancia de la comunicación no-verbal. El objetivo del presente artículo es aportar una herramienta para medir y evaluar conductas no-verbales en entrevistas clínicas, basado en el Ethological Coding System for Interviews (ECSI), desarrollado por Troisi (1999), el cual se tradujo y validó en español. Un etograma es un catálogo de conductas o patrones conductuales, operacionalizados y agrupados en categorías, como afiliación, evasión, asertividad, relajación, entre otras. Método Estudio 1. El etograma ECSI fue traducido al español. Tres observadores "ciegos" registraron las frecuencias de los patrones conductuales del paciente. Los registros se realizaron en intervalos de 15 segundos durante los primeros y últimos 10 minutos de la entrevista clínica. Se obtuvo una validez interobservador de r=0.989, p<0.001. Estudio 2. Con base en el primer estudio se consideró pertinente agregar patrones conductuales, así como reacomodar y redefinir las categorías propuestas. Los tres observadores realizaron el mismo procedimiento que en el estudio 1 con una segunda videograbación. Además de las frecuencias de las conductas observadas, se midió la duración de la conducta. Se obtuvo una validez interobservadores de r=0.993, p<0.001. Resultados y discusión Se probó que el ECSI es una herramienta confiable y válida para examinar la conducta no-verbal de pacientes durante entrevistas. Se espera que el ECSI se pueda incluir al proceso diagnóstico durante las sesiones psicoterapéuticas.

Background Psychotherapeutic diagnosis is largely based on verbal explorations and/or psychological tests. In contrast, the relevance of non-verbal communication is often disregarded. Here, we aim to provide a tool to measure and assess non-verbal behavior in clinical interviews, based on the Ethological Coding System for Interviews (ECSI), developed by Troisi (1999), which was translated and validated in Spanish. An ethogram is a catalogue of behaviours or patterns of behaviour, which are operationalized and grouped in categories such as affiliation, flight, assertiveness, relaxation and so forth. Method Study 1. The ECSI was translated into Spanish. Three "blind" observers registered the frequencies of the behavioral patterns of the patient. The recordings were made in 15 seconds intervals during the first and the last 10 minutes of a clinical interview. An inter-observer reliability of r=0.989, p<0.001 was obtained. Study 2. Based on the first study, it was considered pertinent to add behavioral patterns, as well as rearranging and redefining the proposed categories. The three "blind" observers performed the same task as in study 1 with a second video-recording. Aside from the frequency of the observed behaviours, the duration of the behavior was measured. An inter-observer reliability of r=0.993, p<0.001 was obtained. Results and discussion The ECSI has proven a reliable and valid tool for the examination of patients' nonverbal behaviour during interviews. It is hoped that the ECSI can be added to the diagnostic process during psychotherapeutic sessions.

Association study between the MDR1 gene and clinical characteristics in schizophrenia

Objective: Schizophrenia is a complex psychiatric disorder, characterized by disturbed patterns of thought and affecting 0.3-2.0% of the world population. Previously, the multidrug resistance 1 (MDR1) gene has been associated with schizophrenia in treatment response studies in psychotic patients. The aim of this study was to determine the association between MDR1 gene polymorphisms and clinical characteristics in patients with schizophrenia. Methods: Positive and negative symptoms of schizophrenia were assessed with the Scale for the Assessment of Negative Symptoms (SANS) and the Scale for the Assessment of Positive Symptoms (SAPS) in 158 Mexican patients with schizophrenia. Analyses of MDR1 gene polymorphisms were performed using TaqMan technology. A multivariate ANOVA was performed with MDR1 polymorphisms and gender as independent variables. Results: Males with the G/G genotype of MDR1 rs2032582 presented significantly higher levels of delusions (p = 0.02). When comparing female vs. male groups, the difference was statistically significant (p = 0.0003). Analyses of the MDR1 gene rs1045642 variant showed no significant differences. Conclusion: Our findings suggest that male carriers of the G allele of variant rs2032582 exhibit greater severity of delusions; however, these results should be taken as preliminary, and replication studies in other populations of different ethnic origins are required to confirm these findings. .

Asociación de los trastornos externalizados y la edad de inicio en pacientes con trastorno bipolar tipo I y II ¿Son los síntomas de los trastornos externalizados predictores de una edad de inicio más temprano? / Association between externalizing disorders and age of onset in patients with bipolar disorder type I and II. Are the externalizing disorders symptoms predictors of an earlier onset?

Background Early onset mania (MIMT), compared with adolescent onset mania (MIA), has a different clinical presentation of classic mania adult onset (MIEA). Patients with MIA have a course more like the MIEA. Externalizing disorders (ADHD, ODD, and TC) have been associated with an earlier age of onset of bipolar disorder and as a marker of poor prognosis. Our goal is to determine the frequency of symptoms related to disruptive behavior disorders in patients with bipolar disorder start very early, early and adult evaluated retrospectively. Methods The total sample (N=64) of adolescent and adult patients was obtained from the National Institute of Psychiatry (INPRF) clinics. The diagnosis was confirmed by the research team. Patients signed the informed asentment and consentment. We applied the K SADS PL Mexico, MINI and MINI KID. We used the EEPE-AA for externalizing disorders. Results There were significant differences in scores compared by EEPE AA EIED groups in the Inattention subscale for GIMT. The presence of ADHD, ODD, TC and Suicide Risk in the time of evaluation was significantly associated with an earlier onset. Discussion and conclusion Our data supports the clinical utility and importance of separating the TBP by age of onset. The detection of externalizing disorders may speak of an early onset of the disorder and may also have implications for prognosis and psychopharmacological treatment, since the TBP-onset childhood to adulthood remains similar and difficult to manage. This suggests that we must have a longitudinal view of this disorder.

Antecedentes La manía de inicio muy temprano (MIMT), comparada con la manía de inicio en la adolescencia (MIA), tiene una presentación clínica distinta a la manía clásica de inicio en la adultez (MIEA). Los pacientes con MIA tienen un curso más parecido a la MIEA. Los trastornos externalizados (TDAH, TND y TC) se han asociado con una edad de inicio más temprano del TBP y como un marcador de mal pronóstico. Nuestro objetivo es determinar la frecuencia de los síntomas relacionados con los trastornos de la conducta disruptiva en pacientes con TBP de inicio muy temprano, temprano y en el adulto evaluados de manera retrospectiva. Método La muestra total (N=64) de pacientes adolescentes y adultos se obtuvo de distintas clínicas del Instituto Nacional de Psiquiatría (INPRF). El diagnóstico fue confirmado por el equipo de investigación y se solicitó la firma del asentimiento y consentimiento informado. Se aplicaron el K SADS PL México, MINI y MINI KID. Se utilizó la EEPE-AA para los trastornos externalizados. Resultados Se encontraron diferencias significativas en las puntuaciones del EEPE AA comparadas por los grupos de EIED, en la Subescala de Inatención para el GIMT. La presencia de TDAH, TND, TC y riesgo suicida en el momento de la evaluación se relacionó significativamente con un inicio más temprano. Discusión y conclusión Nuestros datos apoyan la importancia y utilidad clínica de separar el TBP por edad de inicio y la detección de trastornos externalizados podría hablarnos de un inicio temprano del trastorno. Asimismo, tiene implicaciones en el pronóstico y tratamiento psicofarmacológico, ya que el TBP de inicio en la infancia permanece en la adultez con características similares, así como de difícil manejo. Es necesario tener una visión longitudinal de este padecimiento.

Alfabetización en salud mental en el trastorno bipolar: Asociación con la percepción de agresividad y el género en estudiantes de medicina / Mental health literacy in bipolar disorder: Association with perception of aggressiveness and gender of medical students

Introduction Developing mental health literacy in students and health professionals in general implies gaining abilities in recognizing and treating mental illnesses. In bipolar disorder, this is an important issue due that it helps reducing stigma and the treatment gap found in patients with this diagnosis. Objective To determine the associations between some variables of mental health literacy (illness, recognition, attributable causes and suggested treatment) about bipolar disorder with gender and perception of aggressiveness/dangerousness in a group of medical students. Material and methods One-hundred and three medical students from a public university in Mexico City completed the Aggressiveness Public Concept Questionnaire to assess mental health literacy and aggressiveness/dangerous-ness perception. Results 59.6% of students did not recognize the presence of a mental illness. As described symptoms were not considered as a manifestation of a mental disorder, 83.7% considered non-psychiatric interventions as the most adequate alternative for the management of the behaviors exposed in the vignette. 87.7% considered that the person described in the vignette was aggressive and 33.7% perceived the subject as dangerous. Discussion Campaigns of mental health literacy for medical students must be directed to improve recognition of the essential features of bipolar disorder, therapeutic options as well as the real prevalence and methods of prevention of aggressiveness of these patients.

Introducción La alfabetización en salud sental (ASM) por parte de estudiantes y profesionales de la salud implica su capacidad para reconocer la enfermedad mental y su adecuado manejo, y constituye un elemento esencial para reducir el estigma y la brecha de tratamiento de los pacientes con trastorno bipolar (TBP). Objetivo Determinar la asociación entre algunas variables de la ASM (reconocimiento, causas atribuibles y tratamiento sugerido) para el TBP con el género y la percepción de agresividad en un grupo de estudiantes de medicina. Material y métodos Ciento tres estudiantes de pregrado de la carrera de Medicina de una Universidad pública de la Ciudad de México completaron el Cuestionario de Concepto Público de Agresividad (CPA) para valorar la ASM y la percepción de agresividad/peligrosidad. Resultados El 59.6% de los estudiantes no reconocieron la presencia de una enfermedad mental. Al no considerar los síntomas como la manifestación de una enfermedad mental, el 83.7% sugirió intervenciones no psiquiátricas/no restrictivas para el manejo adecuado de las conductas expuestas en la viñeta clínica. El 87.7% de los estudiantes consideró que la persona descrita era agresiva y el 33.7% la percibió como peligrosa. Discusión Las campañas de ASM para estudiantes de medicina deben abocarse a incrementar el conocimiento de las características esenciales del TBP, las opciones de tratamiento así como la prevalencia real y métodos de prevención de la agresividad en estos pacientes.

Recognition of facial expression of the emotions and their relation to attachment styles and psychiatric symptoms: Preliminary study on Psychiatric Residents / Reconocimiento de la expresión facial de las emociones y su relación con estilos de apego y síntomas psiquiátricos: Estudio preliminar en Residentes de Psiquiatría

Facial expressions of emotion reveal complex mental states that have physiological correlates and signal internal states such as distress to others and are thus crucial in social interaction. In this preliminary study, we therefore sought to examine the link between current psychiatric symptoms and attachment styles in psychiatry residents and their ability to correctly identify facial expressions of emotions. Specifically, we hypothesized that greater current psychiatric symptoms and insecure attachment would be related to difficulties in deciphering facial expressions of negative emotions. A total of 56 psychiatry residents were included in the study, together with 50 university students pursuing careers unrelated to mental health. In order to evaluate the subjects' psychiatric symptoms, the Checklist (SCL-90) and Attachment Styles Questionnaire (ASQ) were used and in order to examine the ability to recognize facial expressions of emotion, we chose the Pictures of Facial Affect (POFA). All the respondents gave their informed consent in writing. The control group recognized fear significantly less as compared to psychiatry residents. Among psychiatry residents, there was a significantly positive correlation between hostility and fear recognition and anxiety and fear recognition. The same was observed between obsessive-compulsive symptoms and disgust recognition. In the control group, there was a significantly negative correlation between paranoid ideation and phobic anxiety with sadness recognition. In resident psychiatry, happiness recognition was positively related to an attachment-style based on confidence, while sadness recognition and surprise recognition correlated negatively with an attachment style based on considering relationships as being of secondary importance. This is one of the first studies to examine emotion recognition skills in medical professionals, and the association of this ability with psychiatric symptoms and attachment styles. We think it is important to observe longitudinally what the possible relevance of these findings might be for both diagnostic accuracy and therapeutic relationships.

La expresión facial de las emociones revela estados mentales complejos que tienen correlatos fisiológicos y señales de estados internos, como la angustia, y que son esenciales en la interacción social. En el presente estudio preliminar examinamos la asociación entre los síntomas psiquiátricos, los estilos de apego y la habilidad para reconocer correctamente la expresión facial de las emociones básicas, en residentes de psiquiatría de una institución de salud mental de México. La hipótesis es que los síntomas psiquiátricos y el estilo de apego inseguro pueden estar relacionados con una dificultad para descifrar la expresión facial de emociones negativas. Un total de 56 residentes de psiquiatría fueron incluidos en el estudio junto con 50 estudiantes universitarios de la Universidad Nacional Autónoma de México, UNAM, de carreras diferentes a las relacionadas con la salud mental. Se utilizaron los siguientes instrumentos: Los síntomas psiquiátricos se evaluaron con el SCL-90, traducido y validado al español, el Cuestionario de Estilos de Apego (ASQ) traducido y validado al español, y para el reconocimiento de la expresión facial de las emociones se usó el Instrumento de Ekman, denominado Pictures of Facial Affect (POFA). Previamente, todos los participantes dieron su consentimiento informado con la firma de aceptación para participar en el estudio. Los estudiantes del grupo control reconocieron menos el miedo que los residentes de psiquiatría. En los residentes hubo una correlación positiva entre la hostilidad y el reconocimiento del miedo y entre la ansiedad y el reconocimiento del miedo. Lo mismo se observó entre los síntomas obsesivos-compulsivos y el reconocimiento del disgusto. En el grupo control se encontró una correlación negativa entre la ideación paranoide y la ansiedad fóbica con el reconocimiento de la tristeza. En los residentes el reconocimiento de la felicidad se relacionó positivamente con el estilo de apego basado en la confianza, mientras que el reconocimiento del miedo y la sorpresa fueron negativamente relacionados con el estilo de apego basado en considerar las relaciones como secundarias. Este es un primer estudio que examina la habilidad de reconocer las emociones básicas en profesionales de la medicina que están siendo entrenados en la especialidad de psiquiatría, y la relación con síntomas psiquiátricos y estilos de apego. Consideramos importante el estudio de estos factores a lo largo de la formación, por la posible relevancia que estos hallazgos puedan tener para el adecuado diagnóstico y la relación terapéutica.

Registro Electrónico de Adherencia al Tratamiento de Esquizofrenia en Latinoamérica (e-STAR): Resultados clínicos del uso de risperidona inyectable de liberación prolongada a dos años de seguimiento / Electronic Schizophrenia Treatment Adherence Registry in Latin America (e-STAR): Clinical outcomes of long-acting injectable risperidone in a 2-year follow up

Schizophrenia is a chronic psychiatric disorder associated to high healthcare costs mainly driven by inpatient care. Lack of adherence to antipsychotic treatment is a common reason for relapse and rehospitalization leading to poor prognosis and global functional impairment of patients. Risperidone long-acting injection (RLAI) has demonstrated its efficacy in treating symptoms of schizophrenia and offers the potential to improve adherence to treatment. Objective To determine clinical and functional efficacy of RLAI and use of health resources (eg., hospitalizations) in a 2-year follow up study among patients with schizophrenia from Latin America. Method The electronic Schizophrenia Treatment Adherence Registry (e-STAR) is an observational study of patients who start treatment with RLAI. Data from patients recruited in Mexico, Colombia and Brazil were collected retrospectively for one year prior to baseline, at baseline and every three months for 24 months. Hospitalization rates and treatment regime were registered. Efficacy was assessed using the Clinical Global Impression of Illness-Severity Scale (CGI-S), while the Global Assessment of Functioning (GAF) and the Personal and Social Performance (PSP) were used for the evaluation of functioning. Results Seventy-three patients completed the two-year follow-up. The proportion of patients hospitalized declined from 16.4% before treatment to 4.1% after 2 years of treatment with RLAI. Only 2.7% discontinued the treatment due to lack of efficacy. Significant improvements were reported in illness severity as well as in global functioning assessed by the CGI-S, GAF and PSP scales, respectively. Discussion Our results give further support of the efficacy of RLAI for the treatment of schizophrenia. Additional to symptom severity reduction and functional recovery, improved treatment adherence and reduced hospitalization rates were observed with the use of RLAI. In a real world clinical setting, RLAI offer an effective long-term treatment for patients with schizophrenia, with a lower use of healthcare resources.

La esquizofrenia genera elevados costos al sistema de salud. La falta de adherencia al tratamiento es una de las principales causas de recaídas y hospitalizaciones en la esquizofrenia. Lo anterior conduce a un pobre pronóstico y deterioro funcional de los pacientes. La risperidona inyectable de liberación prolongada (RILP) ha demostrado su eficacia en el tratamiento de la esquizofrenia, ofreciendo la posibilidad de que los pacientes tengan una mayor adherencia terapéutica. Objetivo Determinar la eficacia y efecto sobre la funcionalidad y el uso de recursos hospitalarios de la RILP en una muestra de pacientes con esquizofrenia de América Latina a dos años de seguimiento. Método El Registro Electrónico de Adherencia al Tratamiento de Esquizofrenia en Latinoamérica (e-STAR) es un estudio observacional del uso de la RILP en la esquizofrenia. Se reclutaron pacientes de México, Colombia y Brasil. Se registró la información clínica del paciente un año previo al inicio del tratamiento con la RILP y de forma prospectiva cada tres meses hasta cumplir los 24 meses de seguimiento. Se registraron las hospitalizaciones y el esquema de tratamiento con la RILP. La escala de Impresión Clínica Global-Gravedad (CGI-S) se utilizó como indicador de eficacia mientras que la Escala Global de Funcionamiento (GAF) y la Escala de Desempeño Personal y Social (PSP) se utilizaron para evaluar el funcionamiento. Resultados Setenta y tres pacientes completaron los dos años de seguimiento. La proporción de pacientes hospitalizados disminuyó del 16.4 al 4.1% después de dos años de tratamiento con la RILP. El 2.7% descontinuó el tratamiento debido a falta de eficacia. Se observó una mejoría significativa en cuanto a la gravedad del padecimiento y el funcionamiento global. Discusión En la práctica clínica cotidiana, la RILP resulta ser un tratamiento a largo plazo efectivo para la esquizofrenia con el beneficio adicional de una menor utilización de recursos del sistema de salud.

Estudio de traducción, adaptación y evaluación psicométrica del Inventario de Miedos FSSC-II en una muestra de estudiantes de educación media superior / Translation, adaptation and psychometric properties of the Fear Inventory FSCC-II in a Mexican sample of high school students

Normal fear is defined as a reaction to a real or imagined threat and is considered an integral and adaptive feature related to the primary function of survival. Nevertheless, when fear is intense and maladaptive, it may lose its role for survival and may progress in a phobic disorder with a negative impact for the individual who suffers it. According to some researchers, childhood and adolescence are the main life periods where phobias and other anxiety disorders develop. It is estimated that up to 50% of children and adolescents report one or more intense fears and more than 20% of these meet diagnostic criteria for specific phobias, frequently related to the development of future mental disorders during adulthood. In the assessment of fear, it is important to consider the evaluation of its intensity as well as its frequency among three main dimensions: the subjective dimension (including feelings and thoughts), the physical dimension (e.g., tachycardia and paleness) and the behavioral dimension (e.g., avoidant behaviors). So far, the main fear assessment methods include self-reports, observation and psychophysiological registers. In the area of mental health, the Fear Survey Schedule for Children II (FSSC-II) is the most widely used instrument for the assessment of fears in youth population. The cultural adaptation of an internationally instrument such as the FSSC-II brings the opportunity for subsequent comparison of investigation findings with other populations. The FSSC-II is an updated version of the original instrument as it includes other type of fears such as fear of war and/or AIDS designed to both children and adolescents. Since it is possible that some mental disorders in adulthood are conditioned by the presence of fears in early stages of life, it is important to have an objective characterization of the main fears in our culture. On this basis, adequate psychopathology prevention programs and treatment strategies can be designed and tested. In general, psychopathology is influenced by the cultural context and fears are not the exception as they tend to manifest differently from one cultural context to another. Therefore, the aim of the present work was to translate, culturally adapt and examine the psychometric properties of the FSSC-II in a Mexican sample of high school students. Method A total of 5030 high school students who accepted to participate in the study were recruited. Age ranged between 14 and 24 years old. The FSSC-II is composed of 78 items scored in a three-point Likert scale that assess frequency and intensity of different fears classified in five main dimensions: fear of death and danger, fear of the unknown, fear of failure or criticism, fear of animals and physical stress-medical fears. Before the enrollment procedure, the FSSC-II was adapted for Mexican population. First, translation-back translation was performed by two independent translators. Some items of the instrument were culturally adapted by consensus to reach the final version of the instrument. A principal component analysis with varimax rotation was performed to determine the construct validity of the instrument in Mexican population. Cronbach's alpha was used to determine the internal consistency of each domain and total score of the FSSC-II. All analyses were performed with the 10th version of the SPSS-X. Results A total of 2992 women and 2038 men participated. Mean age was of 16.43±1.2 years old. For the Mexican adaptation of the FSSC-II, 1 1.53% of the items (n=18) were culturally adapted. Factor analysis showed five factors for the instrument. These factors were consistent with those described in the original version: fear of death and danger, fear of animals or injuries, fear of failure or criticism, fear of the unknown and medical fears. Internal consistency of the FSSC-II was .96. Alpha coefficients for four dimensions were above .80, except the "medical fears" dimension (.70). Discussion The Spanish version of the FSSC-II among Mexican high school students showed adequate psychometric properties. The adaptation process implicated the modification of some items of the original instruments in order to reach a correct assessment of the proposed constructs of the instrument according to the predominant cultural patterns of Mexico. On the other hand, some items were not modified and were taken literally from either U.S. or Australian versions. Although more than 10% of the items were adjusted, the factor structure of the instrument remained congruent with the original version and the U.S version of the FSSC-II. The Mexican version was totally compatible with the five constructs found in the U.S. version; nevertheless it is important to remark that the content of the Mexican version was more compatible with the content of the items of the Australian version. Some of the inconsistencies found between the three versions may be the result of the subjects' age in the studies. The U.S. study included subjects with ages between 8 and 11 years, the Australian study included subjects between 7 and 18 years old, while our study included subjects with ages between 14 and 24 years old. The way children experience reality is not the same as that of adolescents or adults. It is possible to assume that the fears of children are more related to immediate, concrete stimuli, while the ones of adolescents and young adults are related to anticipatory or abstract stimuli. For example, the item of "Fear of being scolded by the principal" can be experienced by a child as something extremely dangerous and, therefore, the item will classify in the dimension "fear of death and danger" and not in the dimension of "fear of failure or criticism" where the answer of an adolescent or a young adult is most likely to be classified. Despite the disparities between the three versions, the FSSC-II showed high internal consistency values and an adequate percentage of explained variance in our sample. These results highlight the utility of the FSSC-II for the assessment of the frequency and intensity of fears in both adolescents and young adults in Mexico. It would be desirable to perform future studies among children.

El miedo es una emoción que se experimenta a lo largo de la vida y en ocasiones posibilita la adaptación. No obstante, el miedo puede tornarse desadaptativo y evolucionar hacia un trastorno fóbico que impacta negativamente en el individuo que lo padece. La infancia y la adolescencia son las etapas en las que típicamente inician las fobias, las cuales se han asociado al desarrollo de otros trastornos mentales en la vida adulta. En la evaluación del miedo es necesario evaluar tanto su intensidad como su frecuencia en tres dimensiones principales: la subjetiva, la física y la conductual. Los principales métodos de valoración del miedo han sido los autoinformes, la observación externa y los registros psicofisiológicos. En el área de la salud mental, la escala más utilizada para la evaluación de miedos en población juvenil es el Inventario de Miedos para Niños II (Fear Survey Schedule for Children II, FSSC-II). La adaptación cultural de un instrumento internacionalmente utilizado como éste brinda la oportunidad de realizar comparaciones subsecuentes de los hallazgos de investigación con otras poblaciones. Dado el impacto del miedo en el futuro desarrollo de trastornos mentales, es importante contar con una caracterización de los principales miedos en nuestra población para la elaboración de futuros programas preventivos y de tratamiento efectivos. De esta forma, el objetivo del presente estudio fue traducir al español, adaptar culturalmente y evaluar psicométricamente el Inventario de Miedos para Niños FSSC-II en una muestra de adolescentes y adultos jóvenes mexicanos. Método La muestra estuvo conformada por estudiantes de preparatoria de ambos sexos, entre 14 y 24 años de edad, que aceptaron participar en el estudio de manera anónima. Dos traductores independientes realizaron la traducción-retraducción y adaptación cultural del FSSC-II y posteriormente fue aplicado a los estudiantes. Se obtuvo la consistencia interna del instrumento mediante el alpha de Cronbach y la validez de constructo mediante un análisis de componentes principales. Resultados Se incluyeron 2992 mujeres y 2038 hombres, con una edad promedio de 16.43 años. El 11.53% de los reactivos de la versión original del FSSC-II se adaptaron para su uso en población mexicana. El análisis factorial mostró cinco factores agrupados de acuerdo con lo teóricamente esperado: miedo a la muerte o peligro, miedo a los animales o lesiones, miedo al fracaso escolar o a la crítica, miedo a lo desconocido y miedos médicos. Todos los factores del FSSC-II mostraron elevados valores de consistencia interna (>.80) con excepción del área de miedos médicos (.70). El alpha de la puntuación total de la escala fue de .96. Discusión La estructura de cinco factores del instrumento resultó congruente con la versión australiana original y la estadounidense, siendo compatible en su totalidad con la versión de Estados Unidos. No obstante, en cuanto al contenido de los reactivos, la versión mexicana del FSSC-II fue más similar a la versión australiana del instrumento. Estas inconsistencias pueden deberse a las diferencias de edades de las muestras sujetas a estudio, siendo distintas las realidades que vive un niño a las que vive un adolescente o un adulto joven. A pesar de estas divergencias, la alta consistencia interna y varianza explicada del instrumento muestran su utilidad para evaluar la frecuencia e intensidad de miedos en adolescentes y adultos jóvenes en nuestro país. Es deseable dirigir futuros estudios para evaluar a niños de menores edades.

Actitudes de mujeres estudiantes de psicología hacia las personas con esquizofrenia: Relación con la percepción de agresividad y peligrosidad / Attitudes of female students of psychology toward people with schizophrenia: Relationship with perception of aggressiveness and dangerousness

Introduction Perception of environment and reality stems mainly from factors determined by social and cultural influences. Several socialization processes promote the development of relations that endorse or reject certain values or identities. Unfortunately, many of these relations arise from prejudiced values that generate negative attitudes such as stigmatization or discrimination toward some persons. According to psychosocial models, generation of stigma is a consequence of three aspects: lack of knowledge about the person's condition (ignorance); development of negative attitudes (prejudice) and a tendency to exclude or reject some individuals (discrimination). Particularly, in mental health problems, general public knowledge of severe mental illnesses such as schizophrenia frequently develops in accordance to myths and misconceptions. For example, schizophrenics are commonly viewed as mad and incompetent individuals that produce fear and rejection. These erroneous conceptions originate from considering that they are incapable of controlling their acts, thus giving rise to aggressive, violent or dangerous conducts. Stigmatization impacts patients increasing depressive symptoms, anxiety and social withdrawal. Stigma also has a negative impact on diagnosis and treatment; timely diagnostic interventions and specialized treatments are frequently delayed in stigmatized individuals. Although it is reasonable to anticipate that stigmatization attitudes are more common among persons with low cultural levels, many studies have demonstrated that unfortunately this problem is also present in many health professionals, including those who work with the mentally ill. For these reasons different attempts have developed to reduce stigma by means of mental health literacy interventions oriented to modify and eliminate misconceptions about mental patients and their illness. In this sense, mental health literacy is defined as any educational intervention aimed to increase recognition, management and prevention of mental illness. Many studies have demonstrated that this type of interventions have a positive impact in reducing negative attitudes toward patients, diminishing in consequence treatment gap. In accordance to this theoretical framework, the principal objective of this study was to evaluate in a group of female psychology students, their attitudes toward mental illness determining their perception of danger and aggressiveness in a schizophrenic patient. We hypothesized that perception of dangerousness and aggressiveness will correlate with more negative attitudes to mental illness. Additionally, we compared attitudes to severe mental illness according to other variables related to mental health literacy such as knowledge of etiology of illness and treatment options, among female student in their first half of their career and female student in their second half. We hypothesized that advanced student will have a higher level of mental health literacy and less negative attitudes to mental illness. Method A total of 110 female psychology students from a university in Mexico City were included in the study. Group's mean age (±SD) was 21.6 (1.7) years (range 19-33 years). All subjects gave their consent to participate in a voluntary and anonymous manner. Sixty five students (59.1%) were at the initial half-stage of their career (1st to 5th semester), and forty five (40.9%) were at their last half-stage (6th to 10th semester). The study was approved by the Institutional Research and Ethical Committees (Instituto Nacional de Psiquiatría Ramón de la Fuente), and by the university's authorities. The Opinions about Mental Illness Scale (OMI), previously translated and standardized in our country (OMI-M), was used to evaluate personal attitudes toward severe mentally ill persons. OMI-M is a 34-item self-report questionnaire which evaluates attitudes utilizing a 5-points Liker scale procedure (1 = totally disagree; 5=totally agree). Evaluation includes six factors: 1. Separatism, which emphasizes the persons' perceived differences about a mental disorder and the desire of keeping a distance to be safe; 2. Stereotyping, defined as conceiving mentally ill persons in accordance to certain behavioral and intellectual patterns; 3. Restrictiveness, which includes items that uphold an uncertain notion regarding the rights of mentally ill persons; 4. Benevolence, which evaluates compassion to the mentally ill; 5. Pessimistic prediction, referring to the perception that mentally ill persons are incapable of improving on their symptoms and how society is also not optimistic in this respect; 6. Stigmatization, build upon items that perceive mental illness as a cause of shame. The Public Aggressiveness Concept Questionnaire, a self-rated instrument was also applied in the study. This questionnaire evaluates the perception of aggressiveness after reviewing a standardized clinical vignette of a patient with an active paranoid schizophrenia. The reviewer is asked to answer questions regarding the identification of aggressive conduct in the vignette, including the presence and intensity of verbal and physical violence. In another section, the way symptoms could be controlled is evaluated. Additional questions are included in the final section of the questionnaire aimed to evaluate concepts such as if the reviewer considers that the person in the vignette has a mental illness, what causes might originate this condition, and if he or she perceives the subject as socially dangerous. Data analysis was carried utilizing the SPSS, version 17.0, statistical program. Categorical variables description was done with rates and percentages; continuous variables were analyzed with means and standard deviation.

Introducción El temor y el rechazo han sido las principales actitudes negativas hacia las personas con trastornos mentales graves como la esquizofrenia. Éstas surgen de la percepción pública de que los pacientes no tienen control sobre su comportamiento y son agresivos, violentos y/o peligrosos; tienen un impacto directo en las personas que padecen esquizofrenia y sus familiares, y aun cuando podría esperarse lo contrario, diversos estudios han mostrado que los profesionales de la salud en general, y de la salud mental en lo particular, muestran actitudes negativas hacia los pacientes con esquizofrenia. Diversos estudios internacionales han demostrado que las campañas dirigidas a incrementar la alfabetización en salud mental (ASM) son efectivas para modificar las actitudes negativas hacia las personas con trastornos mentales. Sin embargo, las necesidades de ASM pueden tener variaciones locales, por lo que resulta necesario conocer las actitudes hacia la enfermedad mental y los factores asociados a las mismas en las poblaciones blanco a las que se dirigirán las campañas antiestigma en una región particular. En esta dirección, el objetivo principal del presente estudio fue comparar las actitudes de mujeres estudiantes de psicología hacia las personas con trastornos mentales graves de acuerdo a la agresividad y peligrosidad percibida de un paciente con esquizofrenia. Adicionalmente, las actitudes hacia las personas con trastornos mentales graves así como las variables relacionadas con la alfabetización en salud mental se comparan entre las mujeres que cursaban la primera mitad de la licenciatura en psicología y aquellas que cursaban la segunda mitad. Método Se incluyó un total de 110 mujeres con una edad promedio de 21.6±1.7 años, estudiantes de la licenciatura en psicología de una universidad de la zona metropolitana de la Ciudad de México que aceptaron participar en el estudio de forma voluntaria y anónima. El 59.1% (n=65) se encontraba cursando la primera mitad de la licenciatura (del 1° al 5° semestre) y el 40.9% (n=45) restante, la segunda mitad (del 6° al 10° semestre). El total de la muestra completó la Escala de Opiniones sobre la Enfermedad Mental en Población Mexicana (OMI-M) para determinar las actitudes hacia las personas con trastornos mentales graves, así como el Cuestionario de Concepto Público de Agresividad (CPA), que valora el concepto público de agresividad del paciente con esquizofrenia con base en la presentación de una viñeta clínica de un paciente con esquizofrenia paranoide. Resultados El 95.5% (n=105) de las estudiantes reconocieron la presencia de una enfermedad mental en la viñeta clínica. No obstante, tan sólo el 70.9% (n=78) consideró las intervenciones psiquiátricas como las más adecuadas para el control de los síntomas. El 59.1 % (n=65) de las estudiantes consideró que el sujeto descrito en la viñeta podría ser agresivo de alguna forma y tan sólo 12.7% (n=14) lo calificó como peligroso para la sociedad. Las estudiantes que percibieron agresivo al paciente de la viñeta mostraron mayores puntajes en las áreas de restricción, predicción pesimista y en la puntuación total del OMI-M. De forma similar, aquellas que consideraron peligroso al paciente tuvieron mayores actitudes negativas en términos de separatismo, estereotipos y puntuación total del OMI-M. No se encontraron diferencias en las variables de alfabetización en salud mental (reconocimiento de la enfermedad, causas atribuibles y tratamiento sugerido), ni en la percepción de agresión y peligrosidad, ni en cuanto a las diferentes áreas evaluadas por el OMI-M entre alumnas que cursaban la primera mitad de la licenciatura en psicología y aquellas que cursaban la segunda mitad. Discusión Un alto porcentaje de estudiantes de psicología consideró agresivo al paciente descrito en la viñeta, y tal como se esperaba, esta concepción se relacionó con mayores actitudes negativas, tales como mayor nivel de restricción y de predicción pesimista. Adicionalmente, la percepción de la persona con enfermedad mental como alguien con capacidades limitadas y comportamiento extraño parece promover la distancia social. Tanto la percepción de agresión como la de peligrosidad y las actitudes negativas asociadas en esta muestra nos hablan del poco entendimiento que pudieran tener los estudiantes de psicología en relación con las experiencias vividas por los pacientes. Aun cuando nuestros resultados no pueden ser generalizados al total de los estudiantes de psicología del país, es posible sugerir la inclusión al currículo educativo de información clara y objetiva sobre aspectos psicosociales de la enfermedad -estigma y actitudes hacia la enfermedad- y no sólo aspectos teóricos sobre la fisiopatología del trastorno y características sintomáticas del padecimiento; así como el contacto regular, tanto hospitalario como comunitario, con los pacientes.

Características demográficas y clínicas asociadas a la dependencia a benzodiacepinas en pacientes psiquiátricos / Demographic and clinical features related to benzodiazepine dependence in psychiatric patients

Introduction Inappropriate use and dependence to prescription drugs has been considered as a growing health problem in recent years. It has been recognized that benzodiazepines (BZD) are one of the most commonly prescribed drugs due to their rapid therapeutic effect, high efficacy and favorable side effect profile when compared to other psychotropic medications. Despite the desirable therapeutic actions of BZD, mainly for the treatment of anxiety disorders, concerns about the dependence producing or addictive nature of these drugs have been expressed for decades. BZD dependence, unlike dependence to other substances, is a condition generally circumscribed to a therapeutic framework. It is well known that BZD use generally starts legitimately by a medical prescription for the treatment of anxiety symptoms or insomnia. Persons with psychiatric disorders are at a greater health risk for BZD dependence than other groups as BZD are highly used for the treatment of several psychiatric symptoms. BZD dependence in these patients may have a negative clinical impact in the medical treatment of the primary psychiatric disorder and may also affect patients' quality of life as the BZD dependence is added as a comorbid diagnosis that also requires clinical management. In this way, the need for clinical useful information for the prevention or early detection of BZD dependence emerges. Although inconsistent associations have been encountered in the scientific literature, some sociodemographic variables, such as gender and level of education, as well as the characteristics of BZD use, have been identified as potential risk factors for the development of BZD dependence. This information is of easy access for the mental health professional during the initial or subsequent clinical interview with patients, and if significant findings are obtained in Mexican psychiatric patients, these variables may become useful clinical tools for a closer follow-up of those patients with high risk of presenting BZD dependence. Objective To determine sociodemographic variables and characteristics of BZD use that may be risk factors for the development of BZD dependence in a sample of psychiatric patients from Mexico City. Method Subjects. Subjects were consecutively recruited at the outpatient services of the Instituto Nacional de Psiquiatría Ramón de la Fuente (INPRF) in Mexico City. All patients with BZD consumptions were included indistinctly of their psychiatric diagnosis of attendance in the institution. All patients gave their written informed consent after receiving a comprehensive explanation of the nature of the study. The Ethics Review Board of the INPRF approved the study. Assessment procedure Psychiatric diagnoses were made with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) and BZD dependence was determined with an adapted version of the substance dependence section of the SCID-I designed to assess BZD use exclusively. Sociodemographic features and characteristics of BZD use were registered in a previously designed format and information was obtained by a personal interview with each patient and main caregiver. The Benzodiazepine Dependence Questionnaire in its Mexican version (BDEPQ-MX) is a self-administered questionnaire used to assess the subjective experience with BZD in the last month in three main areas: perceived dependence, BZD pleasant effects and perceived need of BZD consumption. Results The sample comprised 150 psychiatric patients. A total of 70.0% (n=105) were women and 30.0% (n = 45) were men. Their mean age was 45.9±14.1 with a mean educational level of 11.6±3.9 years. Diagnoses of the sample were mainly anxiety disorders (n = 76, 50.7%) and affective disorders (38.0%). According to the SCID-I, a total of 73 (48.7%) patients met the diagnostic criteria for BZD dependence. Sixty seven percent of the men included in the study reported BZD dependence in contrast to 41.0% of the women. Also, patients with BZD dependence exhibited a higher level of education and a longer time consumption of BZD. A longer duration of BZD consumptions was the main indicator for BZD dependence conferring a risk 10.4 higher for its development. Male gender and psychiatric diagnoses different to anxiety and affective disorders were also significant predictors for BZD dependence. Discussion Numerous potential risk factors relating to BZD dependence have been found and our results support the influence of sociodemographic features and characteristics of BZD consumption for dependence development in a Mexican sample of psychiatric patients. In general, it has been described that men are more prone to substance abuse and dependence and our results showed this same pattern. Nevertheless, this result must be replicated in future studies as for BZD dependence men and women may exhibit similar patterns of consumption and dependence. High rates of BZD prescription, coupled with an elevated risk of substance dependence in diagnoses different to anxiety disorders, highlight the need for a careful review of the costs-benefits of BZD use for the treatment of anxiety emergent symptoms, as other additional medications with lower dependence effect can be used to minimize the potential risk of BZD dependence in these patients. One of the biggest controversies surrounding BZD use has been its long-term use, which has been reported and replicated in our studies as the main indicator for BZD dependence development. Treatment with BZD may be useful for short-term periods of time, and specific goals and objectives of their therapeutic benefits must be established since the initial treatment plans for each patient. The clinical relevance of the present study relies in standing out the high prevalence of BZD dependence found in patients treated with BZD and had not been treated for this comorbid condition. It is important to promote in the mental health professional attendance team strategies for the prevention and early detection of BZD dependence in psychiatric patients.

Introducción El uso inapropiado de los fármacos de prescripción y la dependencia a ellos conforman un problema de salud que va en aumento en la actualidad. A diferencia de la dependencia a otras sustancias, la dependencia a BZD es una condición generalmente circunscrita a un marco terapéutico, ya que el primer contacto frecuentemente se presenta en un contexto clínico. Por el es necesario contar con información que pudiera ser de utilidad clínica para prevenir o detectar de forma oportuna la dependencia en pacientes tratados con BZD. Objetivo Determinar las variables sociodemográficas relacionadas con el patrón de consumo de BZD que pudieran ser predictoras de dependencia a BZD en una muestra de pacientes psiquiátricos de la Ciudad de México. Método Sujetos. Se reclutó a los pacientes que acudieron de forma consecutiva al servicio de Consulta Externa del Instituto Nacional de Psiquiatría Ramón de la Fuente (INPRF) que presentaron uso de BZD, indistintamente del diagnóstico psiquiátrico por el que acudieron a recibir atención especializada. Instrumentos El diagnóstico psiquiátrico y de dependencia a BZD de los pacientes se realizó mediante la entrevista SCID-I. Los principales datos sociodemográficos y las características del consumo de BZD fueron registrados en un formato diseñado ad hoc. El Cuestionario de Dependencia a Benzodiazepinas en su versión para México (BDEPQ-MX) se utilizó para evaluar la experiencia subjetiva del consumo de BZD. Resultados Se incluyó a un total de 150 pacientes con una edad promedio de 45.9±14.1 años. El 48.7% de los pacientes presentaron dependencia a BZD. Los pacientes con dependencia a BZD fueron con mayor frecuencia hombres, con una mayor escolaridad y presentaron un mayor tiempo de consumo. El ser hombre, presentar un diagnóstico distinto a un trastorno de ansiedad o afectivo y tener un mayor tiempo de consumo de BZD fueron los principales factores predictores de dependencia en el presente estudio. Discusión Los hallazgos del presente estudio sustentan la influencia de variables demográficas y del consumo de BZD en el riesgo para desarrollar dependencia. Se observa un mayor riesgo para el desarrollo de dependencia en los hombres. Para los pacientes con diagnósticos distintos a los trastornos de ansiedad es necesario evaluar el costo-beneficio de utilizar las BZD como parte del tratamiento para el manejo de síntomas relacionados con la ansiedad. El uso crónico de BZD fue el principal predictor de dependencia en la presente investigación, lo que pone de manifiesto la importancia de restringir el uso de BZD a periodos cortos de tiempo, estableciendo metas y objetivos claros de sus beneficios terapéuticos. Es fundamental fomentar en el personal médico y paramédico la prevención y detección oportuna de la dependencia a BZD en pacientes psiquiátricos.

Uso inapropiado de fármacos de prescripción: dependencia a benzodiazepinas en adultos mayores / Prescription drugs misuse: benzodiazepine dependence in the elderly

Misuse and potential abuse of prescription drugs are growing problems in elderly people over 65 years old. Although the prevalence of this condition is difficult to estimate, drug misuse is most common in elderly women. A great proportion of the psychoactive prescriptions in old people include tranquilizers and hypnotics. There are several risk factors related to increased risk misuse, abuse, and dependence of prescription drugs. The following are among these risk factors: the female gender, social isolation, history of substance abuse or dependence, history of mental illness and medical exposure to prescription drugs with abuse potential. Also, BDZ consumption for a period longer than four weeks has also been associated to BDZ dependence, even at therapeutic doses. Until now, BDZ dependence in the elderly has been poorly studied, so the present study may increase our knowledge of this complex phenomenon. Objective The aim of the present study was to describe and compare sociodemographic and clinical features related to the prescription and benzodiazepines use in old people with and without dependence to these drugs in an outpatients psychogeriatric service. Method A total of 39 patients from the outpatients service at the psychogeriatric clinic of the National Institute of Psychiatry Ramón de la Fuente in Mexico City were recruited. All of the participants signed an informed consent to be included in the study. Several assessments were performed to determine the psycho-pathological status. Diagnosis of BDZ dependence was obtained with the SCID-I Interview, the severity of depression and anxiety symptoms were evaluated through the Montgomery & Asberg Scale (MADRS) and the Hamilton Anxiety Scale, respectively. For the evaluation of the functionality level, the Katz Index and GAF were used. Results No significant differences were found between patients with and without BDZ dependence in terms of social and demographic characteristics and medical comorbidity. The main Axis I diagnoses of the patients were depressive disorder or anxiety disorders. The first medical prescription of BDZ in patients with BDZ dependence was the presence of anxiety symptoms, while for patients without BDZ dependence the aim of BDZ prescription was the treatment of insomnia. The mean age of BDZ use onset and the time of consumption were 57.5 years and 675.2 weeks, respectively. The average dose of BDZ used by the patients was 14.4mg of diazepam equivalents. Significant differences were found between groups in terms of BDZ consumption features. Patients with BDZ dependence exhibited more drug seeking behavior, more abandonment of daily activities, and more tolerance and abstinence symptoms. Patients with BDZ dependence exhibited more prominent symptoms of anxiety and depression than patients without BDZ dependence. Also, these patients had a poorer cognitive performance and lower psychosocial functioning. Discussion BDZ dependence is a complex phenomenon related to the severity of depressive and anxiety symptoms. These symptoms were the main reason for the medical prescription of BDZ. Although BDZ use was indicated for the treatment of anxiety disorders, the use of BDZ in the elderly has been contraindicated for the treatment of depression with anxiety features. The potential risk to develop BDZ dependence in elderly patients can be related to pharmacological variations due to changes in the metabolism process of aging and the interactions with other drugs. Both factors could increase half life of BDZ and their pharmacological effect in the organism. There were statistical differences in the drug-taking pattern of BDZ consumption in the patients. Patients with BDZ dependence had an earlier onset of BDZ consumption and longer use. The chronic use of BDZ is one of the most important risk factors for dependence development. For the present study, BDZ dependence was clinically defined in terms of tolerance and abstinence symptoms. This definition is in accordance to what has been described in international scientific literature as BDZ physiologic dependence. In this way, tolerance and abstinence symptoms might be the main reason why patients with BDZ dependence needed higher BDZ dosages for the treatment of anxiety symptoms. Sociodemographic characteristics in this sample were not related to the presence of BDZ dependence; nevertheless, it has been reported that the female gender and the presence of chronic pain are risk factors for BDZ abuse and dependence. Future longitudinal studies with an increased number of patients should assess the effect of these variables in BDZ dependence development in the elderly. Differences found in terms of cognitive performance may be related to the psychomotor retardation conferred by the use of BDZ, which may in turn have a direct impact on the velocity of mental performance in the patients. Also, the presence and severity of depressive and anxiety symptoms may also have a negative impact on cognitive performance. Generalization of the findings of the present research is limited by sample size. Nevertheless, the relevance of the present results highlight the importance of the careful prescription and inherent risks related to potentially addictive medications. Increasing our knowledge in the prescription of these medications will improve our medical attention and our patients' quality of life.

El abuso potencial y el uso inapropiado de fármacos de prescripción en adultos mayores de 65 años o más está en aumento. Aunque la prevalencia de esta condición es difícil de estimar, se sabe que es más frecuente en mujeres. Una gran proporción de los tranquilizantes e hipnóticos son prescritos a adultos mayores. El género femenino, el aislamiento social y una historia de abuso de sustancias y de trastornos mentales son los principales factores de riesgo asociados al uso inapropiado de fármacos. Por otro lado, el uso prolongado de benzodiazepinas (BDZ) -mayor a cuatro semanas- también se ha asociado al desarrollo de dependencia, aun cuando las BDZ se utilicen a dosis terapéuticas Objetivo El objetivo del presente estudio es describir y comparar las características sociodemográficas y clínicas relacionadas con la prescripción y el uso de benzodiazepinas en adultos mayores con y sin dependencia a las mismas en un servicio especializado de psicogeriatría. Método Se reclutó un total de 39 pacientes de la Clínica de Psicogeriatría del Instituto Nacional de Psiquiatría Ramón de la Fuente en la Ciudad de México. Todos los participantes consintieron por escrito su participación en el estudio. El diagnóstico de dependencia a BDZ se realizó a partir del SCID-I; la gravedad de los síntomas de depresión se evaluó mediante la Escala de Montgomery y Asberg (MADRS); los síntomas de ansiedad, con la Escala de Ansiedad de Hamilton (HAM-A), y el nivel de funcionalidad, mediante el Índice de Katz y el GAF. Resultados No se encontraron diferencias significativas entre los grupos en las variables sociodemográficas y la comorbilidad médica. Los pacientes incluidos cursaron en su mayoría con un cuadro depresivo o algún trastorno de ansiedad como diagnóstico principal. La indicación médica inicial para el consumo de BDZ fue el tratamiento de la ansiedad para los pacientes con dependencia y del insomnio para los no dependientes. La edad de inicio del consumo de las BDZ y el tiempo de consumo fue de 57.5 años y 675.2 semanas en promedio, respectivamente. La dosis promedio utilizada por los pacientes fue de 1 4.4mg en equivalentes de diazepam. Los pacientes con dependencia a las BDZ mostraron una mayor gravedad de los síntomas de depresión y ansiedad, menor desempeño cognoscitivo y menor funcionamiento psicosocial, así como conductas de búsqueda y abandono de actividades relacionadas con el consumo y mayores síntomas de tolerancia y abstinencia a las BDZ. Discusión La dependencia a las BDZ se presentó como un fenómeno complejo relacionado con la intensidad de los síntomas de depresión y ansiedad, un consumo crónico y una mayor dosificación. La depresión con síntomas de ansiedad en el adulto mayor no debería tratarse con BDZ, ya que, además del riesgo de desarrollar dependencia, éstas pueden efectuar negativamente el desempeño cognoscitivo y el funcionamiento global de los pacientes. Al momento de prescribir una BDZ a la población geriátrica se deben tomar en consideración variables sociodemográficas y clínicas de los pacientes. De la misma forma, será necesario evaluar en futuros estudios la influencia de la personalidad y otras variables clínicas sobre el desarrollo de esta dependencia.

Dimensiones de temperamento y carácter en pacientes con primer episodio de depresión mayor / Temperament and character dimensions in first-episode depressed patients

Unipolar depression is considered as one of the main psychiatric diagnosis related to psychosocial functioning impairment. It has been documented that personality features exert a direct influence on how people with depression cope and adapt to the disorder. The relationship between personality traits and depression has been studied in several models. As depressed patients usually exhibit several personality features of more than one personality disorder, a multidimensional theoretical perspective may increase the clinical description of prototypical diagnosis provided by current categorical criteria. The psychobiological model of personality proposed by Cloninger takes into account the respective contribution of neurobiologically-based mechanisms related to adaptative behaviors in response to danger, avoidance and reward, formulating four main temperamental dimensions and three characterological dimensions centered in conscious learning about self-concepts. The four temperament dimensions are: Novelty Seeking (NS) is thought to be related to the behavioral activation system; Harm Avoidance (HA) to the behavioral inhibition system; Reward Dependence (RD) is defined as a bias toward the maintenance of ongoing behaviors; and Persistence (PE) is defined as a tendency to perseverance despite frustration and fatigue. The character dimensions are: Self-directedness (SD) refers to the ability of an individual to control, regulate and adapt behavior to fit the situation in accordance with personal goals and values; Cooperativeness (CO), account for individual differences in identification with and acceptance of other people; and Self-transcendence (ST) refers to spiritual maturity, transpersonal identification and creativity. Several studies that used the psychobiological model or personality reported that personality differences are detectable among persons with a current major depressive disorder when compared to non-depressed. The most frequent finding reported is the association between higher scores in harm avoidance (HA) and depression. Nevertheless, other studies have found that depression is also related with high scores in the temperamental dimension: reward dependence (RD). In terms of character dimensions, it has been reported that depressed patients exhibit low self-directedness (SD) and low cooperativeness (CO). Objetive The aims of the present study were to determine the reliability of the Temperament and Character Inventory (TCI) in a sample of Mexican depressed patients and healthy controls and to compare TCI dimensions between both groups. Method A total of 40 first-episode depressed patients and 40 healthy controls matched by gender, age and length of education were recruited. All patients were recruited from the outpatient service at the Instituto Nacional de Psiquiatría Ramón de la Fuente. Patients were excluded if they had received any psychotropic medication for the treatment of depression, if they had concomitant medical or neurological illness, current substance abuse or a history of substance dependence, history of bipolar disorder; high risk for suicide or were agitated. Healthy controls were recruited from a public university and were not enrolled if they presented any psychiatric disorder or scored ≥ 2 points in any SCL-90 subscale, or verbally reported any aggressive behavior in the week prior to the assessment. Diagnosis of depression was done according to DSM-IV criteria and confirmed by clinical consensus. The Montgomery & Asberg Depression Rating Scale (MADRS) was used to measure depressive symptom severity. Personality dimensions were assessed using the Temperament and Character Inventory (TCI). Results Personality dimensions of the TCI showed moderate to high reliability. Internal consistency was higher for the character dimensions than for the temperament dimensions in both groups. Patients with major depression showed higher scores in the temperament dimension harm avoidance when compared to healthy controls. No significant differences emerged between groups in the dimensions: novelty seeking, reward dependence and persistence. Significant differences emerged between groups in terms of character dimensions. Depressed patients exhibit: lower self-directedness, lower cooperativeness and lower self-transcendence when compared to healthy controls. Discussion Personality assessment in patients with their first depressive episode offers the advantage of reducing biases secondary to the falsification of retrospective report, the effects of illness chronicity and pharmacological treatment on personality. Our results support the idea that the temperament dimension harm avoidance can be consider as an intermediate phenotype for major depression, as it can be a risk factor or may have a direct influence in the way depression is manifest. In terms of character dimensions, lower scores of self-direct edness may be reflected in patients lack of control responses in situations where mature and effectives responses are required. In this way, patients with low self-direct edness may exhibit irresponsible behaviors and a poor impulse control. Low cooperativeness in patients with depression may represent a state characterized by a limited empathy and can be reflected as social intolerance or social isolation. These behavioural changes are frequent depressive symptoms that can be observed by persons that share the environment with the patient. The result of a low self-transcendence in patients with depression raises the possibility that certain beliefs can modify patients' behavior when they cannot conceive their existence as a part of a unified whole. This, in conjunction with lack of transpersonal identification may explain the presence of self-destructive thoughts and behaviors, such as suicide ideation, frequent symptoms observed in patients with depression. In conclusion, our results show that the temperament dimension HA can be associated with vulnerability to depression, while severity of depression may lay in the interaction between constitutional factors and the subjectivity of illness experience conferred by character.

La depresión unipolar se ha considerado como uno de los trastornos mentales que tiene un mayor impacto en el funcionamiento psicosocial de los individuos. Se ha documentado que los rasgos de la personalidad influyen directamente sobre la forma en como las personas con depresión mayor se adaptan y enfrentan este padecimiento. Diversos estudios que han empleado el abordaje multidimensional de la personalidad mediante el modelo psicobiológico de la personalidad de Cloninger, han considerado que la personalidad es un constructo que diferencia a los sujetos que cursan con un trastorno depresivo mayor de los sujetos sin esta patología. El hallazgo más reportado en la bibliografía ha mostrado que una elevada Evitación al Daño (HA) se asocia con la depresión. Sin embargo, otras investigaciones han encontrado que la depresión mayor también se asocia con una mayor Dependencia a la Recompensa (RD). En cuanto a las dimensiones de carácter, se ha encontrado que los pacientes con depresión muestran una Baja Autodirección (SD) y una Baja Cooperatividad (CO). Objetivo Los objetivos del presente estudio fueron determinar la confiabilidad del Inventario de Temperamento y Carácter (ITC) en una muestra mexicana de pacientes con trastorno depresivo mayor y sujetos control, y comparar las dimensiones del ITC entre ambos grupos. Método Se incluyeron 40 pacientes que estuvieran cursando con su primer episodio de depresión mayor y 40 sujetos controles comparados por el método de pares por género, edad y nivel de escolaridad. Los pacientes fueron reclutados del servicio de consulta externa del Instituto Nacional de Psiquiatría Ramón de la Fuente. Los sujetos control fueron reclutados de una universidad pública de la Ciudad de México. El diagnóstico de los pacientes se realizó a partir de los criterios del DSM-IV y fue confirmado mediante consenso clínico. La severidad de los síntomas de depresión fue evaluada mediante la Escala de Depresión de Montgomery & Asberg (MADRS). Las dimensiones de la personalidad en pacientes y controles fue evaluada mediante el Inventario de Temperamento y Carácter (ITC). Resultados Las dimensiones del ITC mostraron una confiabilidad de moderada a alta. Se observaron diferencias significativas entre grupos en la dimensión de temperamento: Evitación al Daño (HA) y en las dimensiones de carácter Autotrascendencia (ST), Cooperatividad (CO) y Autodirección (SD). Discusión La evaluación de la personalidad en pacientes con un primer episodio de depresión permite excluir la falsificación del reporte retrospectivo así como los efectos que la cronicidad del padecimiento o el tratamiento farmacológico tienen sobre la personalidad. La dimensión de temperamento HA puede ser considerada un factor de vulnerabilidad en el desarrollo de la depresión, mientras que la severidad de la depresión podría estar relacionada con la interacción de los factores constitucionales del sujeto y la subjetividad de la experiencia del padecimiento a partir de la conformación del carácter.
