Despite available instruments to assess peritraumatic reactions - such as tonic immobility, dissociation, and panic reactions - content overlap remains an issue. To date, no comprehensive tool integrates these dimensions into a single valid instrument. This study consolidates items from various sources to create a standalone solution, employing both qualitative and quantitative approaches. At several stages, experts examined potential content overlaps and redundancies in item components, supported by psychometric assessments using exploratory structural equation models and confirmatory factor analysis. The 29-item instrument exhibits robust configural and metric properties, including unique items per factor, high reliability, absence of content redundancy, and convergent and discriminant factorial validity. The provisionally named Peritraumatic Response Questionnaire (PTRQ) seems suitable for use in epidemiological studies in its current state. Further refinement may enhance its comprehensiveness and suitability for broader applications. Thus, we propose this instrument for assessing peritraumatic experiences, with potential for future enhancement by continued research.

O artigo investiga o paradoxo da empatia em pacientes com transtorno de personalidade borderline. A hipótese central é que a hipersensibilidade reativa desses pacientes ao inconsciente do outro reflete uma modalidade específica de empatia. O objetivo é explorar as implicações dessa empatia peculiar, sua relação com dinâmicas arcaicas e seu impacto nas relações interpessoais. O método consiste em uma revisão narrativa da literatura e análise de casos clínicos ilustrativos. Os resultados indicam que essa sensibilidade busca estabilizar relações de objeto internalizadas, mas, aliada à desconfiança no comportamento consciente, compromete vínculos interpessoais e contribui para a disfunção social. Compreender essa dinâmica é essencial para reduzir o estigma e aprimorar o manejo clínico.

To estimate the prevalence of one month psychotropic drug use in São Paulo, Brazil, and to assess the gap treatment between the presence of mental disorders and psychotropic drug users. A probabilistic sample of non-institutionalized individuals from the general population of São Paulo (n = 2336; turnout: 84.5%) who were 15 years or older were interviewed by a trained research staff, applying the Composite International Diagnostic Interview 2.1 (CIDI WHO) (depression, anxiety-phobia, OCD\PTSD, alcoholism sections), and an inventory investigating psychotropic drug use during the 12-month and one-month periods immediately preceding the interview. Logistic models were fitted to investigate associations between psychotropic drug use as well as socio-demographic and clinical variables. The one month prevalence of psychotropic drug use in São Paulo was 5.89%, the most commonly used drugs were antidepressants (3.15%) and tranquilizers (2.67%). A higher consumption of psychotropic drugs (overall, antidepressants and tranquilizers) was observed among women (OR:2.42), older individuals (OR:1.04), individuals with higher levels of formal education (1.06), and individuals with a family (OR:2.29) or personal history of mental illness (OR:3.27). The main psychotropic drug prescribers were psychiatrists (41%), followed by general practitioners (30%); 60% of psychotropic drugs were obtained through a government-run dispensing program. Most individuals who obtained a positive diagnosis on the CIDI 2.1 during the previous month were not using psychotropic medication (85%). Among individuals with a diagnosis of moderate to severe depression, 67.5% were not on any pharmacological treatment. There is a change in the type of psychotropic more often used in São Paulo, from benzodiazepines to antidepressants, this event is observed in different cultures. The prevalence of use is similar to other developing countries. Most of the patients presenting a psychiatric illness in the month prior to testing were not receiving any sort of psychiatric medication. This may be explained by a failure to identify cases in primary care, which could be improved (and access to treatment could be facilitated) if professionals received more specialized training in managing cases with mental health problems.

To analyze the association between drug (DAD) and alcohol (AAD) abuse and dependency and criminal and clinical background by gender of prisoners in São Paulo, Brazil. Cross-sectional study, random sample stratified by administrative district, from which prisons and prisoners were selected via random, multistage sampling. Psychiatric diagnoses were made with the CIDI 2.1. Lifetime prevalence and 95% CI were calculated and adjusted via analysis of complex samples. Multinomial logistic regression analysis was carried out with four categories of dependent variables: presence AAD; presence DAD; presence of another mental disorder; no mental disorders. For female alcohol and drug abuse and dependency (ADAD) were combined into a single category. The sample was composed by 1809 interviewed prisoners (1192 men and 617 women). Prevalence of DAD and AAD was 25.2% and 15.6%, respectively, among female prisoners, and 26.5% and 18.5% among males. Male prisoners with DAD were more likely to have a criminal record as an adolescent (OR 2.17), to be a repeat offender (OR 2.85), and to have committed a property crime (OR 2.18). Prisoners with AAD were repeat offenders (OR 2.18). Among female prisoners, ADAD was associated with repeat offenses (OR 3.39), a criminal record as an adolescent (OR 9.24), a clinical or infectious condition (OR 5.09), another health problem (OR 3.04), and violent crime (OR 2.5). The study confirmed an association between drug-use disorders and the criminal and clinical background in the study population. Prisoners with such disorders were more likely to be repeat offenders and to have a criminal record as adolescents. Among female prisoners disorders were also associated with violent crime and health problems, while among males they were associated with property crime. These patterns in clinical and criminal backgrounds illustrate the need for social rehabilitation programs and specific medical treatment for prison populations.

Resilience is a dynamic process involving the interaction between intrapsychic and social factors of risk and protection. For resilience to be recognized there must be a significant threat to the individual, such as a traumatic event, and a good quality of adjustment. The aim of this study was to identify predisposing factors and possible mechanisms associated with resilience to traumatic events in the general population. We conducted a cross-sectional study with a random sample, aged 15-75 years, living in the two largest cities in Brazil, who were exposed to trauma (N = 3,231). Positive adaptation to trauma was defined as the lifetime absence of anxiety (including posttraumatic stress disorder), depression and alcohol related disorders in the presence of at least one traumatic event. Logistic regression models predicting resilience were used to estimate the incidence density ratio. This measure expresses the extent to which the rate of resilience differs from the exposed group to the non-exposed group. Moreover, we explored the relationship between positive/negative affect and resilience, using linear regression models. Male gender was a predisposing factor to positive adaptation (incidence density ratio [IDR] = 1.34; p < 0.001). There was an inverse linear relationship between childhood violence and resilience (IDR = 0.67; 0.53; 0.19; p < 0.001). Our findings suggest that the absence of parental mental disease (IDR = 1.35; p = 0.07) also predisposes individuals to positive adaptation. This study provides results that help to identify vulnerable groups and protective factors that may lead to a positive adaptation following traumatic experiences.

Tonic Immobility is a temporary state of motor inhibition in situations involving extreme fear. The first scale developed for its assessment was the 10-item Tonic Immobility Scale (TIS). However, there are still few studies on its structural (dimensional) validity. The objective of this study was to reassess the factor structure of the TIS applied to representative samples exposed to general trauma of two Brazilian mega-cities. The sample comprised 3,223 participants reporting at least one traumatic experience. In São Paulo (n = 2,148), a Confirmatory Factor Analysis (CFA) first tested the originally proposed two-dimensional structure. This was followed by sequential Exploratory Structural Equation Models to identify the best fitting model, and subsequently tested in Rio de Janeiro (n = 1,075) via CFA. Alternative reduced versions were further explored using the aggregate sample. Model-based Item Response Theory (IRT) location parameters were also investigated. An absence of factor-based convergent and discriminant validity rejected the original proposition. However, the one-dimensional structure still held several residual correlations. Further exploration indicated the sustainability of reduced versions with seven (alternative A) and six (alternative B) items. Both presented excellent fit and no relevant residual item correlation. According to the IRT location parameters, items in alternative B covered a wider range of the latent trait. The Loevinger's H scalability coefficients underscored this pattern. The original model did not hold. A one-factor solution was the most tenable in both large samples, but with significant item residual correlations, indicating that content redundancies persisted. Further reduced and simplified versions of the TIS proved promising. Although studies are yet to be carried out in other settings, it is the authors' impression that the restricted versions of the TIS are already apt for use in epidemiologic studies since the pros tend to outweigh the cons (as outlined in the Discussion section).

To determine the prevalence of psychiatric disorders in the prison population in the State of São Paulo, Brazil. Through stratified random sampling, 1.192 men and 617 women prisoners were evaluated for the presence of psychiatric disorders by the Composite International Diagnostic Interview, 2.1 version, according to definitions and criteria of International Classification of Diseases (ICD-10). The prevalence estimates of mental disorders and their respective 95% confidence intervals were calculated and adjusted for sample design through complex sample analysis. Lifetime and 12-month prevalence rates differed between genders. Lifetime and 12-month prevalence of any mental disorder was, respectively, 68.9% and 39.2% among women, and 56.1% and 22.1% among men. Lifetime and 12-month prevalence of anxious-phobic disorders was, respectively, 50% and 27.7% among women and 35.3% and 13.6% among men, of affective disorders was 40% and 21% among women and 20.8% and 9.9% among men, and of drug-related disorders was 25.2% and 1.6% among women and 26.5% and 1.3% among men. For severe mental disorders (psychotic, bipolar disorders, and severe depression), the lifetime and 12-month prevalence rates were, respectively, 25.8% and 14.7% among women, and 12.3% and 6.3% among men. This is the first large-scale epidemiological study performed with the prison population in Brazil, revealed high rates of psychiatric disorders among men and women. Many similarities, as well as some differences, were found between our results and those of studies conducted in other countries. The differences observed are more likely due to the peculiarities of the prison systems in each country than to the diagnostic criteria adopted in the studies. This fact reinforces the importance of conducting such studies as part of planning and development of appropriate policies for the particular mental health needs of specific prison populations.
