Objective: This study aimed to evaluate whether progression from first drug use to crack-cocaine use differs according to gender, and whether the report of sexual or physical violence impacts the time of progression. Methods: We interviewed 896 crack-cocaine users (548 men; 348 women) from addiction treatment units. Cox regression models evaluated the time of progression from first drug use to crack use. We analyzed gender differences according to the absence or presence of sexual or physical violence, also considering whether violence, when present, had occurred before or after the onset of crack use. Results: Women presented a faster progression to crack use regardless of exposure to sexual or physical violence (p < 0.05). Compared to unexposed men, there was a similar progression for men exposed to sexual or physical violence before the first use of crack (p = 0.167 and p = 0.393, respectively). In both genders, we observed a faster progression among individuals exposed to these types of violence after the onset of crack use (p < 0.01). Conclusions: We found a faster progression to crack use among women and among individuals exposed to sexual and physical violence after the onset of crack use. These results encourage differentiated treatment strategies, focused on gender and individual characteristics.

Abstract Introduction Delinquent behaviors are risky behaviors that increase during puberty and reach their highest peak in late adolescence. It has been proposed that poor decision-making and theory of mind (ToM) are key cognitive processes implicated with delinquency during adolescence, affecting evaluation of risks and impairing appreciation of social norms. Nevertheless, it is not yet clear whether adolescent offenders who are subjected to provisional deprivation of liberty due to conflict with the law (adolescents in conflict with the law [ACL]) might, in fact, present a specific profile with regard to these cognitive processes. Objectives To assess deliberative decision-making and ToM among adolescents in conflict with the law and adolescents not in conflict with the law. Methods The sample comprised 62 participants: ACL (n = 29) and a control group (CG) (n = 33). ToM was assessed with the Reading the Mind in the Eyes Test (RMET) and decision-making was assessed with the Columbia Card Task (CCT). Substance use, callous-unemotional traits, childhood maltreatment, and intelligence quotient (IQ) were also assessed. Results ACL had more ToM errors for negative mental states in comparison to CG, but not for error rates concerning neutral and positive mental states. With regards to decision-making, our results suggest that ACL group members did not vary their behavior based on the available information and that the risk information had an opposite effect on the number of cards chosen (risk-taking behavior) when compared to CG. Conclusion These findings have important implications for development of interventions for these adolescents, suggesting that they tend to learn little from negative outcomes and have reduced capacity to process negative emotions.

Objective: To compare the working memory (WM) performance of young adult crack-cocaine dependent users, healthy older adults, and a control group of healthy young adults. Methods: A total of 77 female participants took part in this study: 26 young adult crack-cocaine dependent users (CRK), 19 healthy older adults (HO), and 32 healthy younger adults (HC). All participants completed the N-back verbal task. Results: A multivariate analysis of covariance was performed. The model included education, income, and medication use as covariates. A group effect (F6,140 = 7.192, p < 0.001) was found. Post-hoc analyses showed that the performance of the CRK and HO groups was reduced compared to the HC group in two N-back conditions. No differences between the HO and CRK groups on WM performance were found. Conclusions: CRK participants perform similar to HO participants on a WM task, despite the well-known effects of age on WM and the young age of CRK. These data point to a possible parallel between cognitive declines associated with crack use and developmental aging.

Objetivo Este estudo teve como objetivo adaptar a Cocaine Selective Severity Assessment (CSSA) para o português do Brasil e verificar as propriedades psicométricas do instrumento em uma amostra de usuárias de crack. Métodos Após as etapas de tradução e adaptação, 125 mulheres usuárias de crack, internadas em uma unidade pública de desintoxicação, foram avaliadas. Para caracterização da amostra e análise das validades concorrente, de construto e preditiva, foram utilizados os seguintes instrumentos: SCID-I, ASI-6, BDI-II e CCQ-B. Resultados A análise fatorial exploratória identificou cinco fatores, com níveis adequados de consistência interna tanto para os fatores quanto para o escore geral da CSSA. Quanto à validade concorrente, a CSSA vai ao encontro de instrumentos já utilizados na clínica e em pesquisas. Em relação à validade de construto e preditiva, a CSSA pode ser sensível ao declínio dos sintomas de abstinência durante o processo de desintoxicação do crack. Conclusões Nossos achados foram além da tradução e adaptação da CSSA, proporcionando testes de validade e sugerindo que a CSSA é um instrumento confiável na avaliação dos sintomas de abstinência do crack.

Objective This study aimed to describe the translation and adaptation of Cocaine Selective Severity Assessment (CSSA) into Brazilian Portuguese and verify the psychometric properties in a sample of crack cocaine users. Methods After the translation and adaptation steps, 125 female crack cocaine-dependent inpatients who were enrolled in an inpatient detoxification unit were evaluated. To characterize the sample and realize the analysis of concurrent validity, construct validity and predictive validity the following instruments were used: SCID-I, ASI-6, BDI-II e CCQ-B. Results The exploratory factorial analysis identified five factors and revealed appropriate levels of internal consistency, as well as the total score of the CSSA. The concurrent validity showed that CSSA was in line with instruments used in clinical practice and in researches. Further, both construct and predictive validity indicated adequate sensitivity to decline of withdrawal symptoms during the detoxification processes. Conclusions Our findings were beyond the translation and adaptation, providing the reliability and validity of CSSA regarding the evaluation of withdrawal symptoms in crack cocaine abstinence.

Contexto : O transtorno de humor bipolar (THB) é marcado por estratégias de enfrentamento, ou coping, que determinam comportamentos que podem influenciar negativamente o curso da doença. Traços de personalidade são altamente associados com estratégias de coping, portanto se faz a hipótese de que traços de personalidade influenciem as estratégias de coping de portadores de THB. Objetivo : Este estudo buscou investigar associações entre traços de personalidade e estratégias de coping em pacientes com THB. Métodos : Trinta e cinco participantes eutímicos diagnosticados com THB e 40 controles saudáveis participaram deste estudo. Estratégias de coping foram avaliadas com a Ways of Coping Checklist Revised and Brief – COPE – e traços de personalidade foram avaliados com o Neo Personality Inventory. Resultados : Participantes com THB possuíram padrão de estratégias de coping significativamente mais baseados na emoção. Em termos de traços de personalidade, participantes com THB tiveram significativamente mais características de neuroticismo e reduzidas características de extroversão e consciência. Foram encontradas associações positivas entre índices de neuroticismo e estratégias de coping baseadas em emoções e associações negativas com estratégias baseadas no problema. Conclusão : Traços de personalidade são fundamentais para as estratégias de coping de pacientes com THB, portanto traços de personalidade devem ser considerados alvos terapêuticos para a psicopatologia.

Background : Bipolar disorder is marked by alterations in coping skills which in turn impacts the disease course. Personality traits are associated with coping skills and for this reason it has been suggested that personality traits of patients with BD may have influence over their coping skills. Objective : To investigate possible associations between coping skills and personality in individuals with bipolar disorder (BD). Methods : Thirty-five euthymic subjects with BD were compared with 40 healthy controls. Coping skills were evaluated using Ways of Coping Checklist Revised and Brief-COPE. Personality traits were assessed by Neo Personality Inventory. MANCOVA was used for between groups comparison. Results : Regarding coping, individuals with BD reported more frequent use of emotion-focused strategies than problem-focused strategies, and high levels of neuroticism and low levels of extroversion and conscientiousness on personality measures. Neuroticism influenced negatively the use of problem-focused strategies, and positively emotion-focused coping. Conscientiousness influenced the use of problem-focused strategies in both groups. There was a significant difference between emotion focused coping and personality traits between BD and control groups. Discussion : Personality traits seem to modulate coping skills and strategies in BD which may be took into account for further interventions.

Objective: To translate and adapt to Brazilian Portuguese the Revised Reading the Mind in the Eyes Test (RMET), in both paper-and-pencil and computerized versions. The RMET is a well-accepted instrument for assessment of Theory of Mind (ToM), an important component of social cognition. Methods: Following a guideline for translation of material for clinical populations, this study had three main phases: 1) formal translation and semantic adaptation to Brazilian Portuguese; 2) an acceptability trial with health professionals as judges evaluating picture-word matching; and 3) a trial using the paper-and-pencil and computerized versions (experiments built in E-Prime 2.0.10 software) with healthy participants to test whether the instrument has similar outputs to those expected in versions in other languages. Results: RMET was adequately adapted to Brazilian Portuguese. This version showed acceptability and outputs similar to versions of the instrument in other languages, including the original one. We kept the same number of images as the original English version. Conclusions: Considering the scarcity of cognitive assessment instruments adequately adapted to Portuguese and the importance of social cognition in many psychiatric disorders, this work adds an important resource to Brazilian research and is administrable in both paper-and-pencil and computerized versions.

A depressão em idosos é associada com prejuízos cognitivos, entretanto a extensão destes à Memória de Trabalho (MT) ainda não é consensual. Portanto, o objetivo deste estudo é revisar sistematicamente as associações encontradas entre MT e depressão em idosos. Para tanto conduzimos uma revisão sistemática dos artigos publicados entre 2000 e 2011 nas principais bases de dados internacionais. Posteriormente a aplicação dos critérios de exclusão, 17 artigos foram revisados integralmente. Os resultados apresentam evidências da associação entre depressão geriátrica e prejuízos da MT, que em alguns trabalhos ainda foram mantidos mesmo após a remissão da sintomatologia de humor.

Geriatric depression is related with cognitive impairments, but how this is connected to specific Working Memory deficits is still unknown. Hence, the aim of this study is to systematically review the literature about the associations between Working Memory impairments and major depression in the elderly. Thus we performed a systematic review, considering published articles in major international databases between 2000 and 2011. After exclusion criteria, 17 articles were fully reviewed. There is evidence that there is indeed an association between depression in elderly and Working Memory impairments. In addition, some articles found that such deficits are sustained even after mood symptoms remission.

Las funciones ejecutivas constituyen un conjunto de habilidades que incluye la resolución de problemas, la planificación, la iniciación, el autocontrol, la conciencia ante situaciones nuevas y la capacidad de modificar los planes si es necesario. Se trata de funciones de alto nivel cognitivo, que son cruciales para que una persona mantenga sus actividades diarias y para la promoción de una buena calidad de vida. El déficit en estas funciones se conoce como síndrome disejecutivo (SD). Hay muchos modelos teóricos sobre SD; sin embargo, la literatura no es muy clara en relación con los componentes involucrados ni con la forma de investigar y resolver este problema. Varios estudios muestran que la edad, el consumo de sustancias y la psicopatología pueden afectar a algunas de estas funciones a través de daños en los circuitos frontales asociados a ellos. El efecto de este daño puede poner en peligro las actividades rutinarias del día a día, imponer dificultades en la socialización y afectar su vida laboral. Hay un cuerpo creciente de estudios que tratan de determinar las causas, consecuencias y modelos que son capaces de dar cuenta de estos efectos y promover estrategias de tratamiento más eficaces. Este artículo pretende hacer una revisión de la SD, centrándose en los aspectos relacionados más importantes, tales como las comorbilidades, la reserva cerebral, la reserva cognitiva y los programas de rehabilitación.

Executive Functions (EF) concern a range of abilities including problem-solving, planning, initiation, selfmonitoring, conscious attention, cope with new situations and the ability to modify plans if necessary. It's a high cognitive function that is crucial for a person to get engaged and maintain daily activities whilst keeping a good quality of life. Problems in the EF were formerly known as Dysexecutive Syndrome (DS). There are many models concerning DS, although the literature on the subject still remains unclear. Several works appoint the effects brought by elderly life, as well as abuse of drugs and some psychopathologies. These factors are known to increase the distress of the frontal circuits and that could be associated to executive deficits. The effects of DS would compromise individuals in day-to-day routine, academic, social and labor fields. There is a growing body of studies trying to determine the causes, implications, associations and the best way to take care of these effects. This work intends to review DS, focusing on the most important fields related to this area, such as psychopathology associations, cognitive reserve, assessment and cognitive rehabilitation programs.

As funções executivas constituem um conjunto de habilidades que envolvem o planejamento e a resolução de problemas, desde a iniciação, consciência e auto controle de comportamentos frente a novas situações, além da capacidade de modificar tais planos quando necessário. As funções executivas envolvem um alto grau de controle cognitivo e são cruciais para atender as atividades diárias e manter uma qualidade de vida. Os déficits associados a estas funções é denominado Síndrome Disexecutiva (SD). Existem muitos modelos teóricos que procuram elucidar a SD, no entanto, a literatura não é muito clara quanto os componentes envolvidos, formas de investigar e estratégias para resolver estes déficits. Vários estudos apontam que os efeitos da idade, do consumo de substâncias e de psicopatologias podem contribuir para a deterioração de circuitos frontais associados aos déficits executivos, comprometendo ainda mais o funcionamento diário, acadêmico, social e laboral. Existe um vasto campo de estudos visando determinar as causas, implicações, fatores associados e a melhor forma de lidar com estes efeitos. O presente artigo busca revisar estudos acerca da SD, focando em aspectos centrais como psicopatologias, reserva cognitiva e programas de reabilitação cognitiva.

Um dos instrumentos mais utilizados internacionalmente para avaliação da Memória de Trabalho (MT) é a Tarefa N-back Auditiva. Recursos para avaliação desse sistema são escassos no Brasil. O presente estudo objetiva observar o desempenho da Tarefa N-back Auditiva em indivíduos de diferentes faixas etárias: 27 crianças, 22 pré-adolescentes, 26 adultos e 27 idosos. Os resultados mostram que o grupo etário influencia no desempenho da Tarefa N-back Auditiva. A acurácia foi aumentando na transição da infância para a pré-adolescência e seguiu em crescimento até a adultez. Observou-se um declínio no desempenho de idosos. Os dados da Tarefa N-back Auditiva corrobora a trajetória desenvolvimental, sugerindo que essa tarefa possa ser utilizada no contexto experimental. Pesquisas de normatização contribuirão para melhor compreensão dessa tarefa.

One of the most internationally used instruments for evaluation of Working Memory (WM) is the Auditory N-Back Task. In Brazil, resources to evaluate this system are scarce. The aim of this study is to investigate the performance of different age subjects in auditory n-back tasks. We divided the 102 subjects in four groups: 27 children, 22 adolescents, 26 young adults and 27 older adults. The results demonstrate an age-related difference in the n-back task performance. The accuracy increased in the transition from childhood to adolescence and kept growing from adolescence to adulthood. We also found a decrease in the performance of aged subjects. The Auditory N-Back Task results are in agreement with WM development trajectory, and so, it demonstrates to be an adjusted instrument to evaluate this system in experimental setting.

INTRODUÇÃO: A teoria da mente (theory of mind, ToM) é um domínio da cognição social que se refere à habilidade cognitiva de interpretar ou inferir estados mentais de outras pessoas através de conhecimentos prévios. Recentemente, pesquisas têm mostrado que essa capacidade está comprometida em algumas psicopatologias, como esquizofrenia e autismo. Além disso, pesquisadores têm mostrado que déficits na ToM impactam a funcionalidade social e, consequentemente, a qualidade de vida. Apesar do aumento recente de estudos na área, alguns problemas (por exemplo a dificuldade de instrumentos estandardizados para avaliar essa habilidade em diferentes idiomas). OBJETIVOS: Descrever a tradução e a adaptação para o português brasileiro de duas das mais importantes e amplamente utilizadas tarefas de ToM - o Theory of Mind Stories e o Hinting Task. MÉTODO: O processo incluiu as seguintes etapas: 1) tradução; 2) produção de uma versão unificada e avaliada por especialistas; 3) retrotradução para o inglês; 4) revisão da versão em inglês por especialista; 5) adaptação das correções indicadas; e 6) aplicação de estudo piloto em um grupo representativo da população para qual as tarefas foram originalmente desenvolvidas (portadores de esquizofrenia). RESULTADOS: Uma versão final em português foi obtida para cada uma das tarefas. Ambos os instrumentos demonstraram boa compreensão por parte dos participantes e podem agora ser utilizados no contexto experimental brasileiro. CONCLUSÕES: A disponibilização de duas das mais consagradas tarefas de ToM em português brasileiro favorece o desenvolvimento de pesquisas sobre o assunto no Brasil. No futuro, isso pode auxiliar no planejamento de intervenções clínicas direcionadas a indivíduos com dificuldades sociocognitivas.

BACKGROUND: Theory of mind (ToM) is a field of social cognition that deals with the individual’s cognitive ability to interpret or infer the mental states of others based on previous knowledge. Recently, research has shown that this ability is compromised in patients with some psychopathologies, e.g., schizophrenia and autistic disorder. Investigators have also shown that deficits in ToM have impacts on social functioning and, consequently, on quality of life. Even though ToM studies have recently grown in number, some problems still remain (e.g., the difficulty of standardized tools to assess ToM in different languages). OBJECTIVES: To describe the translation and adaptation into Brazilian Portuguese of two of the most important and widely used ToM tasks, namely, the Theory of Mind Stories and the Hinting Task. METHOD: The process included the following steps: 1) translation; 2) production of a single translated version and review by specialists; 3) back-translation into English; 4) review by an English-speaking specialist; 5) adaptation of marked corrections; and 6) pilot application in a group representative of the target population (people with schizophrenia). RESULTS: A final translated version was obtained for each of the tasks. Both instruments were well understood by participants and can now be used in the Brazilian experimental setting. CONCLUSION: The availability of two major ToM tasks in Brazilian Portuguese facilitates the conduction of research on the topic in Brazil. In the future, this could help design clinical interventions aimed at people with social and cognitive difficulties.

The term "social cognition" generally refers to the mental operations that underlie social interactions including the perception and interpretation of the intentions, dispositions, and behaviors of others and the generation of a response to these behaviors. Social cognition has been considered a valuable and promising field that strives to understand the nature and outcome of major mental disorders. This article discusses the concept of social cognition and its relationship to Theory of Mind (ToM). Theory of Mind in autistic spectrum disorders has been studied since the 1980s, and cognitive impairments in these disorders may be restricted to ToM deficits because other cognitive domains and nonsocial intelligence are preserved. This article addresses the issues of human ontogeny, reviews the main findings from research on schizophrenia and bipolar disorder, and summarizes the tools commonly used in the assessment of these illnesses.
