Gaslighting Exposure During Emerging Adulthood: Personality Traits and Vulnerability Paths.

Among the many forms of psychological violence, gaslighting is a particularly insidious manipulative behaviour that includes acts aimed at controlling and altering one's own partner's sensations, thoughts, actions, affective state, self-perception, and reality-testing. The purpose of this study was to evaluate the association between the experience of gaslighting and dysfunctional aspects of the partner's personality. Gaslighter personality facets were assessed using the Personality Inventory for DSM-5-Informant Form-Adult (PID-5-IRF), while gaslighting behaviours were assessed using a 25-item questionnaire, based on the three categories of glamour, good-guy, and intimidator (Stern, 2007). The sample was made up of a group of 177 Italian emerging adults aged between 19 and 26 (49.2% male, 50.8% female; M = 21.88, SD = 1.75), enrolled at University, who participated voluntarily in the research. In fact, none of them received any form of direct or indirect incentive. In our study, we applied a beta regression model mapping the Likert scale into the open interval (0,1). The main results show (a) good-guy gaslighting is positively associated with manipulativeness and negatively associated with deceitfulness; (b) glamour gaslighting has a negative association with separation insecurity and manipulativeness, but it is positively associated with irresponsibility; (c) intimidator gaslighting has a positive association with separation insecurity and distractibility and a negative association with eccentricity and perceptual dysregulation; (d) all three gaslighting categories are negatively associated with anhedonia and impulsivity. Based on what emerged from the data, aspects such as separation insecurity, irresponsibility, and distractibility can be seen as serious risk factors for gaslighting. For this reason, with regard to clinical implications, an early recognition of dysfunctional traits in potential abusers should be fostered in order to protect both potential abusers and their partner from aggressive conduct within an intimate relationship.

Entre las muchas formas de violencia psicológica, el gaslighting es un comportamiento manipulador particularmente insidioso que incluye actos destinados a controlar y alterar sensaciones, pensamientos, acciones, estado afectivo, autopercepción y estado de realidad de la pareja. El propósito de este estudio fue evaluar la asociación entre la experiencia del gaslighting y los aspectos disfuncionales de la personalidad de la pareja. Los aspectos de la personalidad de gaslighting se evaluaron utilizando el Inventario de Personalidad para DSM-5-Formulario de Informante-Adulto (PID-5-IRF), mientras que los comportamientos de gaslighting se evaluaron usando un cuestionario de 25 ítems, basado en las tres categorías de glamoroso, buen tipo e intimidante (Stern, 2007). La muestra estuvo compuesta por un grupo de 177 adultos jóvenes italianos de entre 19 y 26 años (49.2% hombres, 50.8% mujeres; M = 21.88, SD = 1.75), quienes estaban matriculados en la universidad y participaron voluntariamente en la investigación. De hecho, ninguno de ellos recibió algún tipo de incentivo, ya fuera directo o indirecto. En nuestro estudio aplicamos un modelo de regresión beta que mapea la escala Likert en el rango abierto (0,1). Los principales hallazgos muestran (a) que el buen tipo de gaslighting está positivamente asociado con la manipulación y negativamente asociado con el engaño; (b) el gaslighting glamoroso tiene una asociación negativa con la separación, la inseguridad y la manipulación, pero está positivamente asociado con la irresponsabilidad; (c) la iluminación del intimidador tiene una asociación positiva con la inseguridad de la separación y la distracción y una asociación negativa con la excentricidad y la desregulación perceptiva; (d) las tres categorías de gaslighting están asociadas negativamente con la anhedonia y la impulsividad. Según lo que surgió de los datos, aspectos como la inseguridad en la separación, la irresponsabilidad y la distracción pueden considerarse factores de riesgo graves para el gaslighting. Por esta razón, en las implicaciones clínicas, se debe promover un reconocimiento temprano de los rasgos disfuncionales en los abusadores potenciales para proteger tanto a los abusadores potenciales como a su pareja del comportamiento agresivo dentro de una relación.

Development and Validation of Dimensional Clinical Personality Inventory 2 (IDCP-2) Algorithms to Assess ICD-11 Personality Trait Domain Qualifiers.

With the advent of the new diagnostic model for personality disorders in the 11th revision of the International Classification of Diseases (ICD-11), researchers and practitioners in World Health Organization signatory countries are urged to implement it. This study aims to develop a brief, reliable, and valid scale for assessing maladaptive personality traits according to the ICD-11 model, using the item pool of the Dimensional Clinical Personality Inventory (IDCP-2). Quantitative and qualitative criteria for item selection were applied to a sample of 251 Brazilian adults. As a result, the 25 items (five items per factor) were selected, demonstrating promising evidence of validity based on the internal structure with a database of 1,659 Brazilian adults. In addition, we found good evidence of validity based on relationships with external variables, particularly those related to personality pathology, in a sample of 617 Brazilian adults. The implications of these findings are discussed.

Association between personality traits, eating behaviors, and the genetic polymorphisms FTO-rs9939609 and MAO-A 30 bp u-VNTR with obesity in Mexican Mayan children.

Introduction: Genetic variants that control dopamine have been associated with obesity in children through loss of control of satiety and impulses, the manifestation of addictive eating behaviors, and specific personality traits. The variants include FTO-rs9939609 and the MAO-A 30 pb u-VNTR low-transcription alleles (LTA). Objective: To evaluate the genetic association of FTO-rs9939609 and the MAO-A LTA, along with personality traits and eating behavior with obesity in Mayan children from Mexico. Methods: We cross-sectionally evaluated 186 children (70 with obesity and 116 with normal weight) 6-12 years old from Yucatan, Mexico. Nutritional status was defined with body mass index (BMI) percentiles. Personality traits were evaluated with the Conners and TMCQ tests; eating behavior was evaluated with the CEBQ test. Genotyping with real-time PCR and TaqMan probes was used for FTO-rs9939609, whereas PCR amplification was used for MAO-A u-VNTR. Results: High-intensity pleasure (p = 0.013) and moderate appetite (p = 0.032) differed according to nutritional status. Heterozygous FTO-rs9939609 T/A children showed higher mean scores of low-intensity pleasure (p = 0.002) and moderate appetite (p = 0.027) than homozygous T/T. Hemizygous boys having MAO-A LTA showed significantly higher mean scores of anxiety (p = 0.001) and impulsivity (p = 0.008). In multivariate models, only LTA alleles of MAO-A explained obesity in boys (OR = 4.44; 95% CI = 1.18-16.63). Conclusion: In the present study, MAO-A u-VNTR alleles were associated with obesity in multivariate models only in boys. These alleles might also have a role in personality traits such as anxiety and impulsivity, which secondly contribute to developing obesity in Mayan boys.

The relationship between premenstrual syndrome and personality traits in university students

SUMMARY OBJECTIVE: This study was conducted to determine the relationship between personality traits and premenstrual syndrome in university students METHOD: This cross-sectional study was conducted with 616 female university students between February and June 2020. RESULTS: The Premenstrual Syndrome Scale score was determined as a mean of 125.40±25.41. According to linear regression analysis, extrovert/introvert personality traits, emotional balance/neuroticism, and consistent/inconsistent personality traits were statistically significant predictive factors of premenstrual syndrome. CONCLUSION: The results of this study demonstrated that two-thirds of the students had premenstrual syndrome and personality traits affected premenstrual syndrome. It is recommended that attention should be paid to personality traits when coping with premenstrual syndrome.

The relationship between women's personality traits and fear of childbirth, birth satisfaction, and postpartum depression

SUMMARY OBJECTIVE: This study was conducted to determine the relationship between women's personality traits and their fear of childbirth, birth satisfaction, and postpartum depression. METHODS: This cross-sectional study was conducted between April and August 2022 among healthy third-trimester pregnant women aged 18-49 years who applied to the obstetrics and gynecology outpatient clinic of a state hospital. Data were collected by the researchers by face-to-face interview method in three stages. Participants were administered the Personal Information Form, the Five-Factor Personality Scale, and the Birth Anticipation/Experience Scale at the first interview; the Birth Satisfaction Scale on the 10th day after normal birth; and the Edinburg Postpartum Depression Scale 4 weeks after birth. RESULTS: There was a significant positive correlation between neurotic personality traits and fear of childbirth and postpartum depression, while there was a negative correlation with other personality traits (p<0.001). There was no significant relationship between birth satisfaction and personality traits (p>0.05). The effect of personality traits on fear of childbirth and postpartum depression was analyzed by multiple linear regression analysis. The regression model tested for the effect of personality traits on fear of childbirth and postpartum depression was found significant (p<0.001). According to the model, 26% of the variability in fear of childbirth and 9.1% of the variability in postpartum depression were explained by personality traits. CONCLUSION: This study showed that neuroticism, which is one of the personality traits of women, had a positive effect on fear of childbirth and postpartum depression. No significant relationship was found between birth satisfaction and personality traits.

Personality, negative affectivity and emotional intelligence: gender-differentiated relationships with physical exercise.

Introduction: Physical exercise is one of the most relevant lifestyle choices for the prevention of diseases; however, participation in this type of activity remains low. Therefore, it is necessary to deepen the understanding of related psychological factors in men and women. Objective: To determine whether personality traits, emotional intelligence and negative affective are differentially related to physical exercise characteristics in men and women. Method: A cross-sectional study was conducted with 579 physically active people (61.1% men) between 18 and 59 years of age. The Big Five Inventory (BFI-15p), Brief Emotional Intelligence Scale (EQ-i-M20), and Depression, Anxiety and Stress Scale (DASS-21) were used. Results: Compared with men, women exercised fewer days and minutes per week, had fewer years of participation and performed fewer different physical exercises. On the emotional intelligence scale, compared with men, women showed less stress management, adaptability and general mood but greater interpersonal intelligence. With regard to personality traits, compared with men, women showed greater openness, conscientiousness, agreeableness, and neuroticism. In males, heightened levels of general mood and extraversion were associated to a lasting commitment to physical exercise over time. Conversely, in females, depression was negatively associated with the years dedicated to physical exercise. Conclusion: Distinct approaches are essential for men and women, acknowledging the varied ways psychological factors are linked to physical exercise based on gender.

Association Between Suicidal Behaviour and Cannabis and Tranquilizer use, Depression, Aggression and Other Borderline Personality Traits Among Students in Sincelejo, Colombia.

OBJECTIVE: This objective of this study is to examine the association between suicidal behaviour and substance use, depression, aggressiveness and borderline personality traits among adolescents from Sincelejo, a rural city in the north of Colombia. METHODS: This cross sectional study included 352 participants selected by purposive sampling, from a public and a private school located in Sincelejo, Sucre district, in the north of Colombia. Students ages ranged from 12 to 18 years old (mean, 15.09±1.82). The participants completed three screening tools: a socio-demographic questionnaire, a screening instrument to collect information related to the frequency of use of some substances, such as tobacco and cannabis, and a self-report inventory to assess various personality and psychopathology domains. A series of t-tests, ANOVA and linear regression analyses were conducted. RESULTS: Physical aggression (t=7.74; p <0.01), cognitive depression (t=5.03; p <0.01), affective depression (t=8.24; p <0.01), affective instability (t=3.46; p <0.01), few social relationships (t=3.36; p <0.01), self-harm (t=3.45; p<.01), cannabis and tranquilizer use (t=2.83; p <0.05; and t=2.37; p <0.05) had a significant independent relationship with suicidal behaviour. Aggression (t=2.59; p <0.05), components of depression (t=9.03; p <0.01) and borderline personality traits (t=4.12; p <0.01) also predicted suicidal behaviour. CONCLUSIONS: More longitudinal studies are needed in this area to identify the causal relations between the factors studied and the suicidal behaviour of young people in Sincelejo.

Padrões de conduta antissocial e socialização em jovens escolares do sexo feminino / Patterns of antisocial behavior and socialization in young female school teenagers

A taxa de condutas delituosas oficiais praticadas por meninas jovens tem aumentado nos últimos anos. Embora a literatura sugira um viés de gênero nesse fenômeno, ainda predominam estudos voltados ao sexo masculino. O presente estudo teve como objetivo verificar associações entre os aspectos de personalidade do fator Socialização, compatível com traços do Modelo dos Cinco Grandes Fatores, e condutas antissociais (delituosas e divergentes) em jovens escolares do sexo feminino. Uma amostra de 549 jovens respondeu ao Questionário de Comportamentos Juvenis (QCJ) e à Escala Fatorial de Socialização (EFS). A partir das pontuações obtidas na EFS, os dados da amostra foram agrupados, havendo formação de três clusters, com diferentes níveis de engajamento em condutas antissociais. Maior frequência e diversidade de condutas antissociais estiveram associadas a menores níveis de Amabilidade, Pró-Sociabilidade e Confiança nas Pessoas, sugerindo relação entre os aspectos de personalidade e as condutas antissociais avaliadas. São discutidas também possíveis implicações de outros fatores nessa relação.

The rate of official misconduct cases involving young girls have increased in recent years. Although the literature suggests a gender gap in this phenomenon, studies focusing on males still predominate. The present study had as objective verifying the relation between personality aspects of the Socialization factor, compatible with the characteristics of the Big Five Factors Model, and the commitment of antisocial behaviors (criminal and divergent) by young female students. To this end, a sample of 549 adolescents answered the Questionário de Comportamentos Juvenis (QCJ) and the Escala Fatorial de Socialização (EFS). Based on the results obtained in the EFS, the sample was divided into three clusters. Greater frequency and diversity of antisocial behaviors were associated with lower levels of Agreeableness, Pro-Sociability and Trust in People, suggesting a relationship between personality aspects and the antisocial behaviors evaluated. Possible implications of other factors in this relationship are also discussed.

Objetivo: El objetivo de este estudio es examinar la asociación del comportamiento suicida con el consumo de sustancias, síntomas depresivos, agresividad y rasgos de personalidad límite en adolescentes de Sincelejo (Sucre), una ciudad rural del norte de Colombia. Métodos: Este estudio transversal incluyó a 352 participantes seleccionados por muestreo intencional de una escuela pública y privada ubicada en Sincelejo, distrito de Sucre, en el norte de Colombia. Las edades de los estudiantes oscilaron entre los 12 y los 18 anos (media, 15,09 ± 1,82). Los participantes completaron 3 instrumentos de cribado: uno de datos sociodemográficos, uno sobre consumo de algunas sustancias, tales como tabaco y cannabis, y su frecuencia y un instrumento de autoinforme para evaluar varios dominios de la personalidad y algunas psicopatologías. Se realizaron una serie de pruebas de la t, ANOVA y análisis de regresión lineal. Resultados: La agresión física (t = 7,74; p <0,01), el componente cognitivo de la depresión (t = 5,03; p <0,01), el componente afectivo de la depresión (t = 8,24; p <0,01), la inestabilidad afectiva (t = 3,46, p < 0,01), las pocas relaciones sociales (t = 3,36, p < 0,01), las autolesiones (p <0,01; t = 3,45, p <0,01), el cannabis (t = 2,83; p <0,05) y la toma de tranquilizantes (t = 2,37; p <0,05), se asociaron con el comportamiento suicida. La agresión (t = 2,59; p <0,05), los componentes de la depresión (t = 9,03; p <0,01) y los rasgos de personalidad límite (t = 4,12, p <0,01) predijeron el comportamiento suicida. Conclusiones: Se requieren más estudios longitudinales en esta área con el fin de identificar las relaciones causales entre los factores estudiados y el comportamiento suicida de los jóvenes en Sincelejo.

Diseño y validación de un instrumento para evaluar comportamiento contraproducente online. Rasgos de personalidad como predictores de dichas conductas / Design and Validation of an Instrument to Assess Online Counterproductive Behavior. Personality Traits as Predictors of these Behaviors / Desenho e validação de um instrumento para avaliação de comportamento contraproducente online. Traços de personalidade como preditores de tais comportamentos

El presente estudio tuvo como objetivo el diseño y vali- dación de una escala para evaluar comportamiento con- traproducente en línea que incluye el análisis conjunto de conductas destructivas (antisociales) y constructivas (prosociales). Además, se propuso determinar qué ras- gos de personalidad (normales, patológicos, negativos o positivos) predicen dicho comportamiento. Participaron 351 sujetos de población general argentina (156 hombres, 191 mujeres, 2 se identificaron como no binarios), con una edad promedio de 39.35 años (de = 13.79). Para el cumplimiento de todos los objetivos, aparte de la prueba construida, se emplearon los siguientes instrumentos: Big Five Inventory, Personality Inven- tory for DSM-5 Brief-Form, Positive Traits Inventory Short-Form, Dark Triad Scale, y una encuesta diseñada ad hoc para evaluar el uso de internet y redes sociales. El análisis factorial exploratorio reveló una estructura de dos factores orientados a la evaluación de los dos tipos de conductas, que explicaban el 57.5 % de la varianza total. Como resultado, se dio lugar a una escala de 18 ítems con muy buenos valores de fiabilidad ­coeficiente omega­ (conductas destructivas ω = 0.88; conductas constructivas ω = 0.79). Por último, se realizaron análisis de regresión jerárquica que determinaron que los rasgos de la tríada oscura son los que mejor predicen el desarrollo de conductas destructivas, en tanto que los rasgos positivos predicen las conductas constructivas. Palabras clave: rasgos de personalidad; comportamiento en línea; antisocial; prosocial.

The present study aimed to design and validate a scale to assess online counterproductive behavior that includes the joint analysis of destructive (antisocial) and constructive (prosocial) behaviors. In addition, it was studied which personality traits (normal, pathological, negative or positive) predict this counterproductive behavior. 351 subjects from the general Argentine population participated (156 men, 191 women, 2 identified themselves as non-binary), with an average age of 39.35 years (SD = 13.79). In order to achieve the objectives, in addition to the constructed test, the follow- ing instruments were used: Personality Inventory for dSM-5 Brief-Form, Positive Traits Inventory Short-Form, Dark Triad Scale, and a survey designed ad hoc to assess internet and social media sites use. The exploratory factor analysis revealed a two-factor structure ­oriented to the evaluation of the two types of behaviors­ that explained 57.5 % of the total variance. As a result, a scale of 18 items with very good reliability values ­omega coefficient­ (destructive behaviors ω = 0.88; constructive behaviors ω = 0.79) was developed. Finally, hierarchical regression analyzes were performed. The results showed that the Dark Triad traits best predict destructive behaviors, while positive traits predict constructive behaviors.

Exploring Large Digital Bodies for the Study of Human Behavior.

Internet access has become a fundamental component of contemporary society, with major impacts in many areas that offer opportunities for new research insights. The search and deposition of information in digital media form large sets of data known as digital corpora, which can be used to generate structured data, representing repositories of knowledge and evidence of human culture. This information offers opportunities for scientific investigations that contribute to the understanding of human behavior on a large scale, reaching human populations/individuals that would normally be difficult to access. These tools can help access social and cultural varieties worldwide. In this article, we briefly review the potential of these corpora in the study of human behavior. Therefore, we propose Culturomics of Human Behavior as an approach to understand, explain, and predict human behavior using digital corpora.

Dissecting the cross-trait effects of the FOXP2 GWAS hit on clinical and brain phenotypes in adults with ADHD.

The Forkhead box P2 (FOXP2) encodes for a transcription factor with a broad role in embryonic development. It is especially represented among GWAS hits for neurodevelopmental disorders and related traits, including attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, neuroticism, and risk-taking behaviors. While several functional studies are underway to understand the consequences of FOXP2 variation, this study aims to expand previous findings to clinically and genetically related phenotypes and neuroanatomical features among subjects with ADHD. The sample included 407 adults with ADHD and 463 controls. Genotyping was performed on the Infinium PsychArray-24 BeadChip, and the FOXP2 gene region was extracted. A gene-wide approach was adopted to evaluate the combined effects of FOXP2 variants (n = 311) on ADHD status, severity, comorbidities, and personality traits. Independent risk variants presenting potential functional effects were further tested for association with cortical surface areas in a subsample of cases (n = 87). The gene-wide analyses within the ADHD sample showed a significant association of the FOXP2 gene with harm avoidance (P = 0.001; PFDR = 0.015) and nominal associations with hyperactivity symptoms (P = 0.026; PFDR = 0.130) and antisocial personality disorder (P = 0.026; PFDR = 0.130). An insertion/deletion variant (rs79622555) located downstream of FOXP2 was associated with the three outcomes and nominally with the surface area of superior parietal and anterior cingulate cortices. Our results extend and refine previous GWAS findings pointing to a role of FOXP2 in several neurodevelopment-related phenotypes, mainly those involving underlying symptomatic domains of self-regulation and inhibitory control. Taken together, the available evidence may constitute promising insights into the puzzle of the FOXP2-related pathophysiology.

Is emotional support the key to improving emotion regulation? A machine learning approach.

BACKGROUND: According to the emotion regulation process, situation selection comprises actions that increase or decrease the likelihood of being in contexts that foster a certain type of emotion, positive or negative. This concept is complemented by the social basis theory, which starts with the assumption that the primary ecology of humans is characterized by its social components. Thus, reduced access to social relationships increases cognitive and physiological effort, which leads to a decrease in well-being. PARTICIPANTS AND PROCEDURE: In order to make a joint assessment of both concepts, the study used supervised machine learning models to analyze the associations between selected variables of social support, emotion regulation, coping, and several psychological symptoms (somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism). For this purpose, an Argentine sample (N = 812, M age = 44.35, female = 435) was collected through the Internet, nested cross-validations were performed with 8 different learning algorithms and Shapley values were computed for the predictive models that minimized the test errors. RESULTS: The results showed that adaptive strategies have considerable effects on maladaptive strategies, but they do not have significant effects on symptoms. Contrariwise, social support variables have significant effects on symptoms, while they do not have major effects on maladaptive strategies. CONCLUSIONS: It is concluded that the main function of regulatory flexibility does not appear to be a better adaptation to situations, but rather the maintenance of adequate levels of social support, i.e. emotional support received, perception of available emotional support, and perceived comprehension. Further implications are discussed, and a hypothetical model proposed.

Psychoneuroimmunologic Correlates in a Group of Men who Have Sex with Men with Risky Sexual Behaviors / Os Correlatos Psiconeuroimunológicos em um Grupo de Homens que Fazem Sexo com Homens com Comportamentos Sexuais de Risco

ABSTRACT This work aims to know what correlations can be found among psychological, neuropsychological, neurobiological, and immunological measures in a group of men who have sex with men negative for anti-HIV-1/2 antibodies which have sexual risk behaviors. Statistically significant correlations were found among certain behavioral, emotional, personality, neurobiological, and immunological variables. The circuit of interactions among depression, stress, neuroticism, and conscientiousness stands out, which could indirectly explain risky sexual behavior. In summary, there is a relationship between personality characteristics, mood disorders, risk behaviors, and an activated T cell profile.

RESUMO O objetivo deste trabalho é conhecer as correlações que podem ser encontradas entre as medidas psicológicas, neuropsicológicas, neurobiológicas e imunológicas em um grupo de homens que fazem sexo com homens com HIV-1/2 anti-corpos-negativos que se envolvem em comportamentos sexuais de risco. Foram encontradas correlações estatisticamente significativas entre certas variáveis comportamentais, emocionais, de personalidade, neurobiológicas e imunológicas. Destaca-se o circuito de interações entre depressão, estresse, neuroticismo e responsabilidade, que poderia explicar indiretamente o comportamento sexual de risco. Em resumo, há uma relação entre características de personalidade, distúrbios de humor, comportamentos de risco e um perfil de célula T ativado.

Agressividade e psicopatia: um estudo comparativo entre detentos e adolescentes / Aggression and psychopathy: a comparative study between prisoners and adolescents / Agresividad y psicopatía: un estudio comparativo entre prisionesros y adolescentes

A agressividade e a psicopatia estão relacionadas com o funcionamento do córtex pré-frontal (CPF), cuja maturação leva aproximadamente 21 anos. Assim, objetivou-se identificar a existência de diferenças entre um grupo de adolescentes, com no máximo 20 anos de idade, e um grupo de detentos no tocante ao nível de agressividade e psicopatia. Para tanto, contou-se com a participação de 48 detentos do sexo masculino, com idade média de 34,6 (DP = 8,68) e 48 adolescentes do sexo masculino, com idade média de 17,75 (DP = 1,15). Os participantes responderam ao Questionário de Agressão de Buss-Perry, a Levenson Self-Report Psychopathy scale (LSRS) e a um questionário sociodemográfico. Os resultados dos testes Mann-Whitney e teste t de student indicaram a existência de diferenças significativas apenas para a psicopatia secundária, sendo mais característica em detentos. Os achados foram discutidos considerando a relação do desenvolvimento do CPF com fatores ambientais

Aggression and psychopathy are prefrontal cortex (PFC) activity-related and the maturation of this region takes approximately 21 years. Our aim was to assess differences in aggression and psychopathy levels between an adolescent group (máx age 20) and a prisoner group. It counted with a sample of 48 male prisoners mean aged 34,6 (SD = 3.66) and 48 male adolescents mean aged 17,75 (SD = 1.5). The participants answered the Buss-Perry Aggression Questionnaire; the Levenson Levenson Self-Report Psychopathy Scale (LSRS) and a demographic questionnaire. The Mann-Whitney test and the Student's t-test results shown significant differences only for secondary psychopathy, which was higher in the prisoner group. Our findings were discussed considering the relationship between the PFC development and external factors

Psychological suppressive profile and autoantibodies variability in women living with breast cancer: A prospective cross-sectional study.

Breast cancer (BC) is a leading cause of women's morbimortality worldwide. Unfortunately, attempts to predict women's susceptibility to developing BC well before it becomes symptomatic, based on their genetic, family, and reproductive background have proved unsatisfactory. Here we analyze the matching of personality traits and protein serum profiles to predict women's susceptibility to developing cancer. We conducted a prospective study among 150 women (aged 18-70 years), who were distributed into three groups (n = 50): women without breast pathology and women diagnosed with BC or benign breast pathology. Psychological data were obtained through standardized psychological tests and serum protein samples were analyzed through semiquantitative protein immunoblotting. The matching for psychological and immunological profiles was constructed from these data using a mathematical generalized linear model.The model predicted that women who have stronger associations between high-intensity stress responses, emotional containment, and an increased number and reduced variability of serum proteins (detected by IgG autoantibodies) have the greatest susceptibility to develop BC before the disease has manifested clinically. Hence, the present study endorses the possibility of using psychological and biochemical tests in combination to increase the possibility of identifying women at risk of developing BC before the disease shows clinical manifestations.

Tríade Sombria baseada em um modelo de virtudes da psicologia positiva / Dark Triad based on a virtue model of positive psychology / Tríada Oscura basada en un modelo de virtudes de la psicología positiva

A partir de investigações recentes entre variáveis consideradas socialmente desejáveis, como as forças de caráter e virtudes, deu-se início a propostas que visam a analisar como essas características se comportam quando utilizadas de maneira extrema. Um conjunto de traços conhecido por suas características extremas e antagonistas são as variáveis da tríade sombria (maquiavelismo, narcisismo e psicopatia). Este estudo teve como objetivo analisar, a partir de um modelo multivariado, a contribuição das virtudes na explicação da tríade sombria. Participaram 284 adultos, com idades entre 18 a 65 anos (M = 29,06; DP = 9,73); respondendo a Escala de Forças de Caráter e o Short Dark Triad. A partir do modelo restrito de path analysis, os resultados indicaram que as virtudes interpessoais, de coragem, de humanidade e de autorregulação explicaram as dimensões sombrias. Quando sub ou superutilizadas, as virtudes podem atuar como possíveis preditoras de comportamentos socialmente indesejáveis, vide a tríade sombria.(AU)

Based on recent investigations of variables considered socially desirable, such as character strengths and virtues, proposals have been initiated that aim to analyze how these characteristics behave when underused or overused. A set of traits known for their extreme and antagonistic characteristics are the variables of the Dark Triad (Machiavellianism, narcissism and psychopathy). This study aimed to analyze, from a multivariate model, the contribution of virtues in explaining the Dark Triad. Participants were 284 adults, aged 18 to 65 years (M = 29.06; SD = 9.73); who responded to the Escala de Forças de Caráter and the Short Dark Triad. Based on the restricted path analysis model, the results indicated that the interpersonal virtues, courage, humanity and self-regulation explained the dark dimensions. When underused or overused, virtues can act as possible predictors of socially undesirable behaviors, such as the Dark Triad.(AU)

Cat Coat Color, Personality Traits and the Cat-Owner Relationship Scale: A Study with Cat Owners in Mexico.

Studies regarding the cat-owner bond are quite rare, and several aspects merit more research, including personality trait differences in cats related to coat color and the cat-owner relationship. The objectives of the study were to describe, from the perspective of their owners, the personality traits of cats based on their coat colors and to evaluate the relationships among the Cat Owner Relationship Scale (CORS), its subscales and the traits of cats. Therefore, the CORS was translated into Spanish, and its psychometric properties were assessed. For the personality traits of cats, participants answered a 7-point Likert scale indicating the extent to which they agreed with the following characteristics in describing their cats: active, aloof, bold, calm, friendly, intolerant, shy, stubborn, tolerant and trainable. 211 cat owners living in Mexico participated. Owners perceived their cats as being bold and friendly. Gray cats had the highest score for being as shy, aloof and intolerant, while orange cats had the highest scores for being trainable, friendly and calm. Tabbies the highest for bold and active, tricolor cats for stubborn, and bicolor cats for tolerant. The 3 CORS subscales had adequate psychometric properties when evaluated separately. Cat-owner interaction was positively correlated with an active and friendly personality and negatively correlated with aloofness. Emotional closeness was positively correlated with an active, bold and friendly personality, and perceived cost was negatively correlated with boldness.

Esta pesquisa teve como objetivo adaptar a Light Triad Scale para o contexto brasileiro. Foram realizados dois estudos. O primeiro testou evidências de validade baseadas na estrutura interna, e o segundo, as evidências baseadas na relação com outras variáveis. A amostra foi composta por 454 participantes, com idades entre 18 e 64 anos, que responderam a Light Triad Scale, a Escala de Forças de Caráter, a Prosocial Personality Inventory e o Inventário de Competências Emocionais. O instrumento em sua versão brasileira apresentou evidências satisfatórias e demonstrou ser útil para a mensuração de traços positivos de personalidade.

This research aimed to adapt the Light Triad Scale to the Brazilian context. Two studies were carried out. The first tested for evidence based on internal structure, while the second evidence based on relations to other variables. The sample consisted of 454 participants, aged between 18 and 64 years, who responded to the Light Triad Scale, the Escala de Forças de Caráter, the Prosocial Personality Inventory, and the Inventário de Competências Emocionais. The Brazilian version of the instrument presented satisfactory evidence and proved to be useful for measuring positive personality traits.

Factores de personalidad y variables mediadoras en su relación con la participación política de estudiantes universitarios/as / Personality traits and mediating variables in their relationship with the political participation of colleges students

Resumen El trabajo busca validar un modelo teórico predictivo que analiza los efectos directos e indirectos de los factores de personalidad (según el modelo de los Cinco Grandes Factores) sobre la participación política (PP), incorporando variables de la hipótesis de la mediación: valores políticos, auto posicionamiento ideológico, eficacia política interna e interés por la política. Se aplicó un cuestionario a N=555 estudiantes universitarios de Córdoba, Argentina, y se realizaron correlaciones bivariadas y un análisis de caminos con las variables en estudio. El trabajo confirma la relación directa de Extraversión y el auto posicionamiento ideológico con la PP, aunque evidencia que los factores de personalidad presentan sobre todo efectos indirectos en la PP, mediados en primer lugar por valores políticos, luego interés por la política, y finalmente la eficacia política interna.

Abstract The paper's main goal is to validate a predictive theoretical model that analyzes the direct and indirect effects of personality factors (according to the Big Five Factors model) on political participation (PP), incorporating variables from the mediation hypothesis: political values, ideological self-placement, internal political efficacy and interest in politics. A questionnaire was applied to N=555 college students from Córdoba, Argentina, and bivariate correlations and path analysis were performed with the variables under study. The study confirms the direct relationship of Extraversion and ideological self-positioning with PP, although it shows that personality factors have mostly indirect effects on PP, mediated first by political values, then interest in politics, and finally the internal political efficacy.
