Objective: Childhood maltreatment (CM) is a significant risk factor for the development and severity of bipolar disorder (BD) with increased risk of suicide attempts (SA). This study evaluated whether a machine learning algorithm could be trained to predict if a patient with BD has a history of CM or previous SA based on brain metabolism measured by positron emission tomography. Methods: Thirty-six euthymic patients diagnosed with BD type I, with and without a history of CM were assessed using the Childhood Trauma Questionnaire. Suicide attempts were assessed through the Mini International Neuropsychiatric Interview (MINI-Plus) and a semi-structured interview. Resting-state positron emission tomography with 18F-fluorodeoxyglucose was conducted, electing only grey matter voxels through the Statistical Parametric Mapping toolbox. Imaging analysis was performed using a supervised machine learning approach following Gaussian Process Classification. Results: Patients were divided into 18 participants with a history of CM and 18 participants without it, along with 18 individuals with previous SA and 18 individuals without such history. The predictions for CM and SA were not significant (accuracy = 41.67%; p = 0.879). Conclusion: Further investigation is needed to improve the accuracy of machine learning, as its predictive qualities could potentially be highly useful in determining histories and possible outcomes of high-risk psychiatric patients.

ObjectiveTo clarify the relationship between childhood maltreatment and insomnia in middle school students, and to explore the mediating role of post-traumatic stress disorder (PTSD) symptoms and the moderating role of mental resilience involvement. MethodsFrom April to May 2021, a total of 3 412 students in 3 middle schools in a city in western China were selected using convenient sampling method, and all students were assessed by Childhood Trauma Questionnaire (CTQ), Post Traumatic Stress Disorder Scale (PCL), Insomnia Severity Index (ISI) and mental resilience scale. The moderated mediating effect analysis was conducted using Process v3.4. ResultsAmong the middle school students, CTQ scores were positively correlated with PCL and ISI scores (r=0.540, 0.320, P<0.05), and the scores of CTQ, PCL and ISI were negatively correlated with the score of mental resilience scale (r=-0.049, -0.193, -0.132, P<0.05). PTSD symptoms exhibited a partial mediating effect on the relationship between general childhood maltreatment and insomnia (β=0.161, P<0.05), accounting for 80.5% of the total effect. ConclusionAmong the middle school students, the relationship between childhood maltreatment and insomnia is partially mediated via PTSD symptoms, and mental resilience exerts a moderating role between childhood maltreatment and PTSD symptoms.

【Objective】 To explore the effect of childhood maltreatment on clinical symptoms and early efficacy of antipsychotics in patients with schizophrenia. 【Methods】 Totally 73 schizophrenic patients were divided into mild maltreatment group(n=42) and severe maltreatment group(n=31) according to the Child Trauma Questionnaire(CTQ). The Positive and Negative Symptom Scale(PANSS) and Clinical Global Impression(CGI) were measured and compared between the two groups at baseline and 3 weeks after antipsychotic treatment to analyze the correlation between child maltreatment experience and mental symptoms and the response to early treatment of antipsychotics. 【Results】 PANSS positive factor score(P=0.026) and cognitive deficit factor score (P=0.042) were significantly higher in severe abuse group than in mild abuse group. The positive factor was significantly positively correlated with emotional abuse factor in CTQ score(r=0.257, P=0.028), and the cognitive deficit factor was significantly positively correlated with emotional neglect factor(r=0.283, P=0.015). After antipsychotic treatment, the reduction rate of PANSS negative factor in severe abuse group was significantly lower than that in mild abuse group(P=0.035), and had the highest correlation with CTQ physical abuse factor(r=-0.302, P=0.011). 【Conclusion】 The severity of childhood maltreatment experienced by schizophrenic patients is more related to positive symptoms and cognitive deficits, and more childhood maltreatment experience will affect the improvement of negative symptoms by antipsychotics, suggesting a poor prognosis.
Résumé
Abstract Introduction Gender dysphoria (GD) is characterized by a marked incongruence between experienced gender and one's gender assigned at birth. Transsexual individuals present a higher prevalence of psychiatric disorders when compared to non-transsexual populations, and it has been proposed that minority stress, i.e., discrimination or prejudice, has a relevant impact on these outcomes. Transsexuals also show increased chances of having experienced maltreatment during childhood. Interleukin (IL)-1β, IL-6, IL-10 and tumor necrosis factor-alpha (TNF-α) are inflammatory cytokines that regulate our immune system. Imbalanced levels in such cytokines are linked to history of childhood maltreatment and psychiatric disorders. We compared differences in IL-1β, IL-6, IL-10 and TNF-α levels and exposure to traumatic events in childhood and adulthood in individuals with and without GD (DSM-5). Methods Cross-sectional controlled study comparing 34 transsexual women and 31 non-transsexual men. They underwent a thorough structured interview, assessing sociodemographic information, mood and anxiety symptoms, childhood maltreatment, explicit discrimination and suicidal ideation. Inflammatory cytokine levels (IL-1β, IL-6, IL-10 and TNF-α) were measured by multiplex immunoassay. Results Individuals with GD experienced more discrimination (p = 0.002) and childhood maltreatment (p = 0.046) than non-transsexual men. Higher suicidal ideation (p < 0.001) and previous suicide attempt (p = 0.001) rates were observed in transsexual women. However, no differences were observed in the levels of any cytokine. Conclusions These results suggest that transsexual women are more exposed to stressful events from childhood to adulthood than non-transsexual men and that GD per se does not play a role in inflammatory markers.

Objective: Patients with bipolar disorders have a high risk of suicidal behavior. Childhood maltreatment is a well-established risk factor for suicidal behavior. The objective of this study was to examine the association between childhood-maltreatment subtypes and vulnerability to suicide attempts in bipolar disorder using the Childhood Trauma Questionnaire (CTQ). Methods: A literature review was performed using the MEDLINE, Embase, and PsycINFO databases. Thirteen studies met the selection criteria. In the meta-analysis, the Childhood Trauma Questionnaire (CTQ) was used to assess a wide range of childhood maltreatment subtypes, which were analyzed by using a random-effects model to account for the likely variations of true effect sizes between the included studies. Results: In the systematic review, 13 studies met the selection criteria. The CTQ was selected for the meta-analysis to increase the homogeneity of assessment and to encompass a wide range of childhood-maltreatment subtypes. The data were analyzed using a random-effects model. Compared to bipolar non-attempters, bipolar suicide attempters had experienced childhood maltreatment with a significantly higher frequency and had higher total CTQ scores (Hedges' g = -0.38, 95%CI -0.52 to -0.24, z = -5.27, p < 0.001) and CTQ sub-scores (sexual abuse: g = -0.39, 95%CI -0.52 to -0.26, z = -5.97; physical abuse: g = -0.26, 95%CI -0.39 to -0.13, z = -4.00; emotional abuse: g = -0.39, 95%CI -0.65 to -0.13, z = -2.97; physical neglect: g = -0.18, 95%CI -0.31 to -0.05, z = -2.79; emotional neglect: g = -0.27, 95%CI -0.43 to -0.11, z = -3.32). Conclusions: Childhood maltreatment, as assessed by the CTQ, may contribute to an increased risk of suicidal behavior among people with bipolar disorders. Recognizing maltreatment as an etiological risk factor is a crucial step toward furthering science-based preventive psychiatry.

Resumo Este estudo investigou a associação entre a exposição aos maus tratos na infância e a perpetração de violência física nas relações afetivo-sexuais de adolescentes (n = 397; 14-19 anos). Um modelo de mediação foi conduzido para determinar se tais relações podem ser mediadas por Esquemas Iniciais Desadaptativos (EIDs), a partir da abordagem teórica da Terapia dos Esquemas. Além disso, buscou-se verificar se o modelo é invariante para adolescentes do sexo feminino e masculino. Os resultados indicaram que adolescentes perpetradores de violência no namoro, com histórico de maus tratos na infância, tiveram escores significativamente mais altos na perpetração de violência íntima, do que adolescentes sem histórico de maus tratos. Os EIDs do domínio de Desconexão e Rejeição foram considerados mediadores entre a exposição aos maus tratos e a violência no namoro na adolescência, sendo que este modelo se mostrou mais adequado ao sexo feminino. Implicações clínicas destes achados foram discutidas.
Abstract This study investigated the association between exposure to child maltreatment and dating physical violence in the affective-sexual relationship among adolescents (n =397, 14-19 years). A mediation model was conducted to determine whether these associations can be mediated by early maladaptive schemas (EMS), from the Schema Therapy's theoretical approach. Also, it sought to verify the invariant model by gender. The results showed that teen dating violence perpetrators with a history of child maltreatment had significantly higher scores in the perpetration of intimate violence than adolescents with no history of maltreatment. Disconnection and rejection realm schemas were mediators between exposure to child maltreatment and dating physical violence in adolescence, and this model was adequate to females. The clinical implications of these findings were also discussed.

OBJECTIVE: The aims of current study were to determine whether childhood maltreatment contributes to the occurrence of major depressive disorder (MDD) with bipolarity or suicidality. METHODS: In total, 132 outpatients diagnosed with MDD between 2014 and 2015 on the medical records were included. The subjects were divided into two groups according to the presence of childhood maltreatment (CM group) and no childhood maltreatment (NCM group). Depression severity and bipolarity were identified using Beck Depression Inventory (BDI) and the Korean version of Mood Disorder Questionnaire (K-MDQ) respectively on the medical records. In addition, the baseline loud dependence of auditory evoked potentials of 36 patients on medical records were analyzed. RESULTS: The mean total BDI, BDI item 9 (suicide ideation), and total K-MDQ score were significantly higher in the CM group than the NCM group. The number of subjects with bipolarity was significantly higher in the CM than in the NCM group. Furthermore two thirds subjects experienced the significant maltreatment during childhood. The central serotonergic activity of the CM group was also lower than that of the NCM group. CONCLUSION: The findings of this study support that there is a relationship between childhood maltreatment and bipolarity or suicidality in patients with MDD.

OBJECTIVE: The aims of this study were to determine whether childhood maltreatment contributes to the occurrence of major depressive disorder (MDD) with bipolarity, and whether there is a relationship between central serotonergic activity, as assessed using loudness dependence of auditory evoked potentials (LDAEP), and childhood maltreatment. METHODS: Thirty-five MDD patients were stratified according to the presence or absence of childhood trauma into two subgroups, childhood trauma (CT) and no childhood trauma (NCT), using the Korean version of the Childhood Trauma Questionnaire (K-CTQ). The CT group was subjected to further analysis. Several psychometric ratings were also applied. In addition, auditory processing for the loudness dependence of auditory evoked potentials (LDAEP), which was used as a marker of serotonergic activity, was measured before beginning medication. RESULTS: There was a significant difference in total Korean Bipolar Spectrum Disorder Scale score between the CT and NCT groups (t=-2.14, p=0.04). The total K-CTQ score was positively correlated with the total Beck Scale for Suicidal Ideation (BSS) score (r=0.36, p=0.036). In particular, emotional abuse was positively correlated with the total Barratt Impulsiveness Scale (r=0.38, p=0.026), BSS (r=0.38, p=0.025), and Hamilton Depression Rating Scale (HAMD) (r=0.36, p=0.035) scores. There was also a positive correlation between LDAEP and total Hypomania Personality Scale (r=0.49, p=0.02) and HAMD (r=0.58, p=0.004) scores within CT group. CONCLUSION: The findings of this study support that there is a relationship between childhood maltreatment and bipolarity in patients with MDD.

Objectives: To describe the onset pattern, frequency, and severity of the signs and symptoms of the prodrome of the first hypomanic/manic episode and first depressive episode of bipolar disorder (BD) and to investigate the influence of a history of childhood maltreatment on the expression of prodromal symptoms. Methods: Using a semi-structured interview, the Bipolar Prodrome Symptom Scale-Retrospective (BPSS-R), information regarding prodromal symptoms was assessed from patients with a DSM-IV diagnosis of BD. History of childhood maltreatment was evaluated using the Childhood Trauma Questionnaire (CTQ). Results: Forty-three individuals with stable BD were included. On average, the prodrome of mania lasted 35.8±68.7 months and was predominantly subacute or insidious, with rare acute presentations. The prodrome of depression lasted 16.6±23.3 months and was also predominantly subacute or insidious, with few acute presentations. The prodromal symptoms most frequently reported prior to the first hypomanic or manic episode were mood lability, depressive mood, and impatience. A history of childhood abuse and neglect was reported by 81.4% of participants. Presence of childhood maltreatment was positively associated with prodromal symptoms, including social withdrawal, decreased functioning, and anhedonia. Conclusions: This study provides evidence of a long-lasting, symptomatic prodrome prior to first hypomanic/manic and depressive episode in BD and suggests that a history of childhood maltreatment influences the manifestations of this prodrome.

Aims: Over the course of the past decades, studies on child maltreatment have increasingly adopted multiple levels of analysis (particularly by the inclusion of genetics factors) on the basis of the variability in children’s responses to stressful life events. This is a preliminary study on the effects of child maltreatment in a sample of adolescents according to this perspective. Study Design: Case-control study. Methodology: We investigated the moderating effect of COMT Val158Met polymorphism onthe association of child maltreatment with a range of externalizing behavior - assessed by the Child Behavior Check List/6-18 scale - in a sample composed of 52 maltreated children and adolescents and 90 healthy controls aged 10-18. Maltreatment was recorded on the basis of the presence/absence of physical contact. Results: COMT Val158Met polymorphism interacts with physical contact abuse to influence externalizing behavior (p=.04), with both genetic (p=.03) and environmental risk factor (p=.003) having a significant main effect. Similar results were found considering the rule-breaking component of externalizing behavior, and the main effect of maltreatment was highly significant in all analyses performed. Conclusion: This preliminary study supports the hypothesis that the variability in children's responses to maltreatment might be partially explained by individual genetic differences. Considering the presence of physical contact as a risk factor we could explain inconsistence of findings in literature on GxE in maltreatment.
Résumé
OBJECTIVE: Advances in our knowledge of mental disorder (MD) genetics have contributed to a better understanding of their pathophysiology. Nonetheless, several questions and doubts persist. Recent studies have focused on environmental influences in the development of MDs, and the advent of neuroscientific methodologies has provided new perspectives. Early life events, such as childhood stress, may affect neurodevelopment through mechanisms such as gene-environment interactions and epigenetic regulation, thus leading to diseases in adulthood. The aim of this paper is to review the evidence regarding the role of the environment, particularly childhood stress, in the pathophysiology of MD. METHODOLOGY: We reviewed articles that evaluated environmental influences, with a particular focus on childhood trauma, brain morphology, cognitive functions, and the development of psychopathology and MD. RESULTS AND CONCLUSION: MRI studies have shown that exposure to trauma at an early age can result in several neurostructural changes, such as the reduction of the hippocampus and corpus callosum. Cognitive performance and functioning are also altered in this population. Finally, childhood stress is related to an increased risk of developing MD such as depression, bipolar disorder, schizophrenia and substance abuse. We conclude that there is robust evidence of the role of the environment, specifically adverse childhood experiences, in various aspects of MD.
OBJETIVO: Avanços no conhecimento da genética dos transtornos mentais (TM) contribuíram para um melhor entendimento de suas bases fisiopatológicas. No entanto, dúvidas e questões ainda persistem. Estudos recentes têm se concentrado nas influências do ambiente no desenvolvimento de TM, e o advento de metodologias neurocientíficas oferece novas perspectivas. Eventos precoces de vida, como estresse na infância, podem ser capazes de alterar o neurodesenvolvimento através de mecanismos como interação gene-ambiente e regulação epigenética, resultando em patologias na idade adulta. O objetivo deste artigo é revisar as evidências referentes ao papel do ambiente, em especial o estresse na infância, na fisiopatologia de TM. METODOLOGIA: Revisamos artigos que avaliam as influências ambientais, com um foco especial no trauma na infância, na morfologia cerebral, nas funções cognitivas e no desenvolvimento de psicopatologias e TM. RESULTADOS E CONCLUSÃO: Estudos com ressonância magnética demonstram que a exposição a traumas em uma idade precoce pode levar a diversas alterações neuroestruturais, como a diminuição do hipocampo e do corpo caloso. O desempenho e o funcionamento cognitivo também são alterados nessa população. Por fim, o estresse na infância está ligado a um maior risco de desenvolver TM como depressão, transtorno bipolar, esquizofrenia e abuso de substâncias. Concluímos que existem evidências sólidas quanto à importância do ambiente, especificamente das experiências adversas na infância, em diversos aspectos dos TM.

OBJETIVO: Estudar crianças e adolescentes vítimas de violência doméstica da Unidade de Emergência Referenciada Pediátrica (UERP) do Hospital das Clínicas (HC) - Universidade Estadual de Campinas (UNICAMP) e ambulatório especializado, entre janeiro de 2003 e dezembro de 2007, enfatizando o abuso sexual. MÉTODOS: Analisou-se: gênero, idade, procedência e classificação. Para as vítimas de abuso sexual estudou-se: tipo de abuso (estupro), local (doméstico/urbano), duração (aguda/crônica), autor (conhecido; incestuoso), alterações no exame médico, notificação ao conselho tutelar, medicação antirretroviral e sorologias (HIV, Lues, hepatite B e C). Dividiu-se em dois grupos com relação ao tipo de abuso e ao autor e associou-se a gênero, idade e duração. Para a comparação calculou-se o Qui-quadrado ou Exato de Fisher (significância p < 0,05) e a razão de chance prevalente bruta. RESULTADOS: Do total (551), predominou a negligência (33,9%) e abuso sexual (31,9%), sendo 55,9% nas meninas e 50% até 5 anos. Do abuso sexual (95), 80% eram meninas e 58,9% entre 5-10 anos. Observou-se estupro entre 39% e atentado ao pudor em 59,6%; 72,6% foram em área doméstica, 81,1% por autor conhecido, 31,6% por relação incestuosa, 47,4% crônica e 76,5% sem alteração clínicas, sendo 81,1% encaminhados ao conselho tutelar. Medicação antirretroviral foi indicada para 49,1% dos pacientes, e sorologias: HIV em 46 (48,4%), Lues em 42 (44,2%), hepatite B em 44 (46,3%) e hepatite C em 45 (47,4%), todas negativas, mais frequente nas vítimas de estupro (p = 0,00). Ocorreu associação entre estupro e idade (10 e 15 anos p = 0,01) e autor incestuoso e duração crônica (p = 0,01). CONCLUSÃO: Apesar de não refletir a realidade, serve como alerta aos pediatras.
OBJECTIVE: To study children and adolescents victims of domestic violence treated at the Referenced Pediatric Emergency Unit of the Hospital de Clínicas of the Universidade Estadual de Campinas and its specialized outpatient clinic between January 2003 and December 2007, emphasizing sexual abuse. METHODS: The variables gender, age, origin, and classification were studied. For victims of sexual abuse, the following variables were also studied: type of abuse (rape), location (domestic/urban), duration (acute/chronic), perpetrator (known, incestuous), alterations at medical examination, notification to child protection agencies, and antiretroviral medication and serology (HIV, syphilis, hepatitis B and C). Patients were divided into two groups according to the type of abuse and type of perpertrator and they were associated with gender, age, and duration. For the comparison, chi-squared or Fisher's exact test were performed (significance p < 0.05), as well as raw prevalence odds ratio. RESULTS: Of the total cases of abuse (551), neglect (33.9%) and sexual abuse (31.9%) predominated; the victims were female in 55.9% of the cases, and 50% were up to 5 years of age. Of the sexual abuse cases (95), 80% were female, and 58.9% were between 5 and 10 years of age. Rape was observed in 39% and indecent assault in 59.6%; 72.6% occurred in the domestic area, 81.1% by known perpetrator; 31.6% were incestuous, 47.4% were chronic, and 76.5% had no clinical alterations. 81.1% were referred to child protection agencies. Antiretroviral medication was prescribed to 49.1% of patients, and serological tests (HIV in 46 [48.4%], syphilis in 42 [44.2%], hepatitis B in 44 [46.3%] and hepatitis C in 45 [47.4%]%), all of which were negative, were more frequent in rape victims (p = 0.00). There was an association between rape and age (10 and 15 years, p = 0.01) and between incestuous perpetrator and chronic duration (p = 0.01). CONCLUSION: Although this study does not reflect reality, it can be used as a warning to pediatricians.

Epidemiologic studies have found that childhood physical maltreatment affects 31% and 21% of males and females, respectively, and almost one half of cases correspond to severe physical abuse. A recent study carried out in population from four representative regions of our country found that 14% to 21% of adolescents reported a history of physical abuse during childhood. Childhood maltreatment experiences have been found to be associated to development of psychopathology during childhood. In regard to mood disorders, interest has been focused on the relationship between depression and sexual abuse. An explanation to this situation is that both conditions predominantly affect women while physical abuse is more frequent among men. However, physical abuse produces more negative consequences on women's health; severe physical abuse equally affects men and women; moreover, child physical abuse has been significantly associated with depression only in women. The experiences of adverse events during childhood also seem to be associated with dysthymic disorder, a depressive condition of lower symptomatic severity but longer duration than major depression. Nevertheless, data about childhood physical abuse among patients with dysthymic disorder are scarce. One study found that physical and sexual abuses were significantly more frequent among dysthymic and depressed patients in comparison with control subjects. This finding suggests an association between physical abuse and both acute and chronic forms of depression. On the basis of this knowledge, the aims of this study were: a) to determine and compare the frequency of childhood physical abuse among women with major depression or dysthymic disorder in a community mental health centre; b) to determine psychiatric comorbidity in relation to the history of physical abuse; and c) to compare the severity of depressive symptoms and suicide risk between depressed patients (major depression or dysthymic disorder) with or without a history of childhood physical maltreatment. Subjects were recruited from the population seeking psychiatric attention in a community mental health centre. To be included, patients were required to be females, 18-65 years old, literate, meet DSM IV criteria for major depressive disorder or dysthymic disorder, and give their written informed consent. All patients were assessed with the Mini International Neuropsychiatric Interview, the Beck Depression Inventory and the Childhood Physical Maltreatment Index. This self-report instrument was developed as part of the study. It consists of five questions and it showed satisfactory psychometric properties (e. g., inter-item score correlations .54-.67, item-total score correlations .78-.85 and Cronbach's alpha = .88). Eighty patients were studied: 42 with major depression (MD) and 38 with dysthymic disorder (DD). Patients with MD were not significantly different from DD subjects in age (38.0±11.3 vs. 39.8±12.9, respectively; t = -.64, gl 78, p = .52), civil status (64.2% vs 55.2% living with a partner; x² = .67, gl 1, p = .49), education years (9.5±3.2 vs. 10.3±3.1, respectively; t = -1.1, gl 78, p = .25) and occupation (50% vs. 60% dedicated to housework; x² = .89, gl 1, p = .37). Seventy six percent of patients reported a history of childhood physical abuse; there were no significant differences between MD and DD patients (75% vs. 72%, respectively). However, severity of maltreatment showed a tendency to be significantly higher among MD patients (4.88 [DE 4.81] vs. 3.18 [DE 3.10]; t = 1.8, gl 78, p= 07). Women with a history of physical abuse obtained significantly higher scores on depression than patients without it. This association was not dependent on diagnosis. In contrast, suicide risk was not significantly different between patients with or without child physical abuse. The number of comorbid psychiatric disorders showed a marginal association with the history of physical abuse (1.2 -DE 1.0] vs. 0.78 -DE 0.91], t= -1.6, gl 78, p=.09). According to these results, three out of four women with major depression or dysthymic disorder suffered from physical abuse during childhood. This proportion is notably higher than the one found in general population, and it also differs from the prevalence rate reported in previous studies with depressed patients. In one study where authors examined 1019 patients admitted in a psychiatric hospital, they identified a history of child physical abuse in 12.3% and 8.3% of MD and DD patients, respectively. Later, a rate of 16% and 29% among MD and DD patients was reported. More recently, an epidemiologic study found a rate of 40.3% among women with major depression. The disparity in the reported prevalence rates might have several explanations. Some studies have used definitions of childhood physical maltreatment which seem to correspond to a severe form. For example, in one study it was defined as the experience of being hit hard or often enough to leave bruises, draw blood, or require medical attention. Another one included some other aggressive behaviors (being pushed, grabbed or shoved), but they were not considered as maltreatment if they had had a low frequency. The inclusion of these behaviors, which could be classified as <
De acuerdo con estudios epidemiológicos en México, 18% de los adultos y de 14 a 21% de los adolescentes afirman haber recibido golpes durante su niñez por parte de alguno de sus padres. Las experiencias de maltrato en la infancia se han asociado con el desarrollo de psicopatología en la edad adulta. Sin embargo, en el caso particular de la depresión mayor, el interés se ha concentrado en la relación existente con la historia de abuso sexual. Uno de los argumentos que se han planteado es que ambas condiciones son más frecuentes en la mujer, mientras que el maltrato físico lo es en hombres. No obstante, el abuso físico tiene más consecuencias negativas en la salud de las mujeres. Se ha identificado que no existen diferencias significativas entre las mujeres adultas con historia de abuso sexual y aquéllas con antecedente de abuso físico, con respecto a los síntomas físicos y psicológicos que experimentan. Además, la historia de maltrato físico se asocia significativamente con la presencia de depresión sólo en las mujeres. En conjunto, esta información sugiere que el maltrato físico puede cumplir un papel más importante del que se ha pensado en el desarrollo de la depresión. La experiencia de eventos adversos en la infancia también parece asociarse con el curso y pronóstico del trastorno distímico, aunque la información con respecto a este trastorno es escasa. Por lo anterior, en el presente trabajo nos propusimos: a) determinar y comparar la frecuencia del maltrato físico en la infancia en mujeres con trastorno depresivo mayor y trastorno distímico en un centro comunitario de salud mental; b) determinar la comorbilidad psiquiátrica asociada con la historia de maltrato físico; y c) comparar la gravedad de la sintomatología depresiva y del riesgo suicida en función de la historia de maltrato físico y el diagnóstico. Se estudiaron mujeres, de 18 a 65 años de edad, alfabetas, con diagnóstico de trastorno depresivo mayor o trastorno distímico (DSM-IV) y que aceptaran participar otorgando su consentimiento informado por escrito. Las participantes fueron evaluadas con la Mini Entrevista Neuropsiquiátrica y respondieron el Inventario de Depresión de Beck (IDB) y el Índice de Maltrato Físico Infantil (IMFI). El IMFI es un instrumento autoaplicable que se desarrolló como parte de la investigación. Inicialmente se elaboraron 59 reactivos sobre experiencias de maltrato en la infancia, los cuales fueron clasificados por cuatro jueces clínicos. Cinco reactivos se clasificaron como maltrato físico por tres de los cuatro jueces, por lo que éstos se emplearon para conformar el IMFI. El instrumento mostró propiedades psicométricas satisfactorias: coeficientes de correlación elevados entre los reactivos y la suma total, un alto coeficiente de confiabilidad, y en el análisis factorial produjo un solo componente que explicaba casi 70% de la varianza. Participaron en la investigación ochenta mujeres, 42 con trastorno depresivo mayor (TDM) y 38 con trastorno distímico (TD). El 75 y 72%, respectivamente, reportaron una historia positiva de maltrato físico. La intensidad del maltrato experimentado mostró una tendencia a ser significativamente mayor entre las mujeres con TDM (4.88 [DE 4.81] vs. 3.18 [DE 3.10]; t=1.8, gl 78, p=.07). Las mujeres con historia de maltrato físico obtuvieron calificaciones significativamente más elevadas en el IDB en comparación con las que no lo habían sufrido. Este resultado fue independiente del diagnóstico. En contraste, el riesgo suicida no varió significativamente en función de la historia de maltrato físico. Las pacientes con historia de maltrato físico tendieron a presentar un mayor número de trastornos psiquiátricos comórbidos. En este mismo grupo, la gravedad de la sintomatología depresiva se relacionó significativamente con la gravedad del maltrato (r=0.27, p=.03). Los resultados muestran que aproximadamente tres de cada cuatro mujeres con TDM o TD experimentaron maltrato físico en la infancia. Éste se asocia, además, con una mayor gravedad de los síntomas depresivos y posiblemente con una mayor comorbilidad psiquiátrica. La elevada proporción de mujeres con TDM o TD con una historia de maltrato contrasta con los datos obtenidos en estudios previos. El origen de la discrepancia puede estar, al menos en parte, en la definición empleada, ya que en este estudio se usó una definición más estricta que incluye el maltrato considerado <
Résumé
Objective: To explore childhood traumatic experiences of OCD patients who were also diagnosed personality disorders (PDs) and those without PDs. Methods:SCID-I/P was administrated to diagnose OCD patients. PDQ+4 and PDI-IV were then administrated to 44 OCD subjects to determine whether they also suffered from personality disorders. Childhood maltreatment experiences of the sample were measured with Childhood Trauma Questionnaire (CTQ).50 normal control were also collected and subjected to CTQ-SF tests. Results:32 of 44 (72%) OCD patients also met DSM-IV criteria for personality disorders. OCD patients scored significantly higher than normal control in CTQ-SF (Childhood Truma Questionuaire-28 Short Form) and in all domains with the exception of physical abuse. Comparison between OCD subjects with PDs and normal control, the former scored significantly higher in emotional abuse (55.10/32.54), sex abuse (49.63/36.30), physical neglect (52.03/34.76), and emotional neglect domains (55.84/32.32). Whereas OCD subjects without PDs only scored significantly higher in emotional neglect domains compared with normal control (42.50/28.26).Conclusions:Subjects with PDs experienced more severe traumatic events during their early life. "pure OCD" patients, however, might experienced more emotional neglect.
