Social cognition in individuals with schizophrenia, autism spectrum disorder and controls / Cognição social em indivíduos saudáveis, com esquizofrenia e com transtorno do espectro do autismo

ABSTRACT Objective: The aim of this study was to compare the social cognition profiles of male adults with ASD (n = 15), SCHZ (n = 16) and controls (n = 20). Change the second sentence of the abstract. Methods: A cross-sectional assessment of social cognition domains with emotional face perception with eye tracking was performed, and two IQ measures (Verbal IQ and Performance IQ) (Wechsler Adult Intelligence Scale), and the DSM-IV Structured Clinical Interview were applied. Results: There were no significant differences in terms of average performance in social cognition tests or eye tracking tasks between the ASD and SCHZ groups. However, both had lower performances in most cases when compared to the control group. In the social cognition tasks, individuals in the control group performed better than both clinical groups. Conclusion: Although differences were identified between individuals with ASD and SCHZ, it was not possible to determine patterns or to differentiate the clinical groups.

RESUMO Objetivo: O objetivo deste estudo foi comparar os perfis de cognição social de adultos do sexo masculino com TEA (n = 15), SCHZ (n = 16) e controles (n = 20). Métodos: Foram aplicadas uma avaliação transversal dos domínios de cognição social com percepção emocional com rastreamento ocular, duas medidas de QI (QI verbal e QI de desempenho) (Escala de Inteligência Adulta de Wechsler) e a Entrevista Clínica Estruturada DSM-IV. Resultados: Não houve diferenças significativas em termos de desempenho médio em testes de cognição social ou tarefas de rastreamento ocular entre os grupos ASD e SCHZ. No entanto, ambos tiveram desempenhos mais baixos na maioria dos casos, quando comparados ao grupo controle. Nas tarefas de cognição social, os indivíduos do grupo controle tiveram melhor desempenho do que ambos os grupos clínicos. Conclusão: Embora tenham sido identificadas diferenças entre indivíduos com TEA e SCHZ, não foi possível determinar padrões ou diferenciar os grupos clínicos.

Effects of socioeconomic status in cognition of people with schizophrenia: results from a Latin American collaboration network with 1175 subjects.

BACKGROUND: Cognition heavily relies on social determinants and genetic background. Latin America comprises approximately 8% of the global population and faces unique challenges, many derived from specific demographic and socioeconomic variables, such as violence and inequality. While such factors have been described to influence mental health outcomes, no large-scale studies with Latin American population have been carried out. Therefore, we aim to describe the cognitive performance of a representative sample of Latin American individuals with schizophrenia and its relationship to clinical factors. Additionally, we aim to investigate how socioeconomic status (SES) relates to cognitive performance in patients and controls. METHODS: We included 1175 participants from five Latin American countries (Argentina, Brazil, Chile, Colombia, and Mexico): 864 individuals with schizophrenia and 311 unaffected subjects. All participants were part of projects that included cognitive evaluation with MATRICS Consensus Cognitive Battery and clinical assessments. RESULTS: Patients showed worse cognitive performance than controls across all domains. Age and diagnosis were independent predictors, indicating similar trajectories of cognitive aging for both patients and controls. The SES factors of education, parental education, and income were more related to cognition in patients than in controls. Cognition was also influenced by symptomatology. CONCLUSIONS: Patients did not show evidence of accelerated cognitive aging; however, they were most impacted by a lower SES suggestive of deprived environment than controls. These findings highlight the vulnerability of cognitive capacity in individuals with psychosis in face of demographic and socioeconomic factors in low- and middle-income countries.

Experiência laboral e inclusão social de indivíduos com esquizofrenia / Work experience and social inclusion of individuals with schizophrenia

Resumo Objetivos: compreender os aspectos positivos e negativos das experiências relacionadas ao trabalho relatadas por indivíduos com esquizofrenia, usuários de um ambulatório de especialidades envolvido em um programa de inclusão laboral. Métodos: estudo com abordagem qualitativa e observacional. Onze participantes responderam a uma pergunta norteadora aberta: "o que você percebe como aspectos positivos e negativos na sua experiência de trabalho?". Os dados foram categorizados por meio de análise temática. Resultados: foram identificadas 4 categorias: sobrecarga e falta de informação/orientação no trabalho; a importância da remuneração; assumindo responsabilidades, esperança e superação; a vivência da doença, o cuidado com a saúde e o trabalho. O estudo mostrou a importância de buscar estratégias eficazes de inclusão laboral para indivíduos com esquizofrenia, que considerem as especificidades da doença e os fatores estressantes relacionados ao trabalho como potenciais desencadeadores de sofrimento físico e emocional. Conclusão: é fundamental investir em ações que possibilitem efetiva inclusão laboral de pessoas com esquizofrenia. Tais medidas devem contemplar os portadores de esquizofrenia, suas famílias, as empresas e os profissionais dos serviços de saúde mental. As especificidades da doença, as necessidades, os interesses e o potencial da pessoa devem ser considerados.

Abstract Objectives: to understand the positive and negative aspects of work-related experiences reported by individuals with schizophrenia who use a specialty outpatient clinic involved in a work inclusion program. Methods: observational qualitative approach study. Eleven participants answered an open guiding question: "what do you see as positive and negative in your work experience?". Data were categorized by thematic analysis. Results: four categories were identified: overload and lack of information/guidance at work; the importance of remuneration; assuming responsibility, hope and overcoming; disease experience, health and work care. The study showed the importance of seeking effective labor inclusion strategies for individuals with schizophrenia. These strategies have to consider the disease specificities and work-related stressors as potential triggers of physical and emotional distress. Conclusion: it is essential to invest in actions that enable effective labor inclusion of people with schizophrenia. Such measures should include individuals with schizophrenia, their families, the companies and mental health professionals, taking into accountthe disease specificities, the person's needs, interests and potential.

The Brazilian standardization of the MATRICS consensus cognitive battery (MCCB): Psychometric study.

OBJECTIVE: Translate, adapt, and validate the MATRICS Consensus Cognitive Battery (MCCB) in Brazil. METHOD: The present study followed three steps: 1) translation to Portuguese, cultural adaptation, and back translation to English; 2) completion of a pilot study (N=30) conducted with the purpose of assessing whether the general comprehension of the items was clear and all participants adequately responded to the battery; 3) completion of a Reliability and Validation Study of the Brazilian version of the MCCB with 99 individuals with schizophrenia and 99 healthy subjects. All participants were administered the Structured Clinical Interview for DSM-IV (Diagnostic and Statistical Manual of Mental Disorders) and patients were also rated on the Global Assessment of Functioning (GAF) Scale and the Positive and Negative Symptoms Scale (PANSS). RESULTS: The results showed adequate to high levels of baseline and 4-week retest reliability, except the MSCEIT-ME; adequate internal consistency for the MSCEIT-ME for the total sample and patients group, and moderate Alpha for the health control sample; as well as evidence of convergent validity and sensitivity to differentiate performance between the groups. All the 10 MCCB measures showed the lowest learning effects. CONCLUSION: Overall the Brazilian version of the MCCB showed similar results to the original North American version. Our findings provides reassurance that the MCCB is a reliable and valid measure of cognition across different countries and cultures, which is especially important to the ongoing work in attempting to discover cognition-enhancing drugs and the effects of cognitive interventions for the treatment of schizophrenia.
