Psychometric properties of the Brazilian version of the Cognitive Emotion Regulation Questionnaire / Propriedades psicométricas da versão brasileira do Questionário de Regulação Emocional Cognitiva

Abstract Introduction: The Cognitive Emotion Regulation Questionnaire (CERQ) was developed to measure nine cognitive strategies referring to what someone thinks after the experience of threatening or stressful events. The main purpose of this study was to evaluate the validity of the Brazilian version of the CERQ. Methods: The adaptation process included translation, backtranslation, expert committee evaluation, and test on 30 participants from the target population. A sample of 445 university students completed the Portuguese version of the CERQ, a sociodemographic questionnaire, the Life Events Checklist (LEC-5), and the Positive and Negative Affect Schedule (PANAS) on an on-line research platform. Validity was assessed through confirmatory factor analysis of two models - a nine-factor model and a second-order model. Internal consistency was assessed through Cronbach's alpha analysis and correlations with affective variables measured by the PANAS. Results: The analyses showed that the nine-factor model of the CERQ has good factorial validity and high reliability, with Cronbach's alpha values ranging between 0.71 and 0.88. The second-order model did not have a good fit to the data. Conclusion: The results obtained in this study are similar to the ones found previously, indicating that the Brazilian version of the CERQ is a valid and reliable tool for assessing cognitive emotion regulation strategies, but that grouping them according to their adaptability is not recommended.

Resumo Introdução: O Questionário de Regulação Emocional Cognitiva (Cognitive Emotion Regulation Questionnaire [CERQ]) foi desenvolvido para medir nove estratégias cognitivas que se referem à forma como as pessoas pensam sobre a experiência de eventos ameaçadores ou estressantes. O objetivo principal deste estudo foi desenvolver e avaliar a validade da versão brasileira do CERQ. Métodos: O processo de adaptação incluiu tradução, retrotradução, avaliação de comitê de especialistas e teste em 30 participantes da população-alvo. Uma amostra de 445 universitários completou a versão em português do CERQ, um questionário sociodemográfico, a Lista de Verificação de Eventos de Vida (Life Events Checklist [LEC-5]) e a Escala de Afeto Positivo e Negativo (Positive and Negative Affect Schedule [PANAS]) em uma plataforma de pesquisa online. A validade do instrumento foi avaliada através da análise fatorial confirmatória de dois modelos: um modelo de nove fatores e um modelo de segunda ordem. A consistência interna foi avaliada por meio da análise de alfa de Cronbach e correlações com variáveis afetivas medidas pela PANAS. Resultados: As análises mostraram que o modelo de nove fatores do CERQ possui boa validade fatorial e alta confiabilidade, com valores de alfa de Cronbach variando entre 0,71 e 0,88. O modelo de segunda ordem não se ajustou bem aos dados. Conclusão: Os resultados obtidos neste estudo são semelhantes aos encontrados em estudos anteriores, indicando que o CERQ é uma ferramenta válida e confiável para avaliar as estratégias de regulação cognitiva das emoções, mas que agrupá-las de acordo com sua adaptabilidade não é recomendado.

Influence of family socioeconomic status on IQ, language, memory and executive functions of Brazilian children

Abstract The aim of this study was to assess the effect of family socioeconomic status (SES) and parental education on non-verbal IQ and on the processing of oral and written language, working memory, verbal memory and executive functions in children from different age ranges. A total of 419 Brazilian children aged 6­12 years old, attending public and private schools from Porto Alegre, RS participated in the study. Structural equation analyzes revealed that in the general model (for all ages), the SES contributed to cognitive performance ­ IQ, verbal memory, working memory, oral and written language and executive functions (28, 19, 36, 28 and 25 %, respectively). SES had stronger effects on younger children (up to nine years old), in most cognitive tasks examined. Probably, after this age, a combination of factors such as schooling, living in other social environments, among others, may mitigate the effects of family socioeconomic status.

Propriedades psicométricas da Cocaine Selective Severity Assessment (CSSA) em mulheres usuárias de crack / Psychometric properties of Cocaine Selective Severity Assessment (CSSA) in crack users

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. .

Montreal-Toulouse language assessment battery for aphasia: validity and reliability evidence.

BACKGROUND: In Brazil, no standardized instruments are available to assess language in patients with aphasia. OBJECTIVE: The aim of the current study was to search for reliability and validity evidence for the Montreal-Toulouse Language Assessment Battery (MTL-BR). METHODS: The sample was composed of 537 adults, of whom 463 were healthy individuals and 74 had neurological lesions (25 participants had right hemisphere brain damage, 21 had left hemisphere damage (LHD) with aphasia and 28 had LHD without aphasia). Reliability was assessed by internal consistency (Cronbach's alpha) and test-retest analyses. Test-retest reliability was calculated using the Pearson correlation coefficient, and a repeated measures analysis of variance, with years of education as a covariate. Construct validity was verified by correlations between scores in MTL-BR subtest and similar tasks from other language assessment instruments. RESULTS: Internal consistency was satisfactory (Cronbach's alpha between 0.79 and 0.90), as were correlations between test and retest scores (mean 0.52), and between the MTL-BR and scores in similar instruments. CONCLUSIONS: The present results suggested that the MTL-BR battery had adequate reliability and validity as a method for diagnosing and monitoring aphasia.
