Abstract

Abstract Introduction: Emotion regulation can be defined as the process by which individuals manage their emotional experience. It has been demonstrated that deficits in this ability are associated with various psychiatric disorders. In this direction, the Difficulties in Emotion Regulation Scale (DERS) was developed to measure difficulties in emotion regulation. Objective: To examine the psychometric properties of the Brazilian Portuguese version of the DERS. Method: A total of 377 individuals from the general population, selected by convenience, completed a sociodemographic form, the adapted Brazilian Portuguese DERS and the Depression Anxiety Stress Scale (DASS-21). Factor structure, reliability, and concurrent validity of the adapted version of the instrument were investigated. Results: The confirmatory factor analysis replicated the six-factor structure originally proposed for the instrument and confirmed the acceptability of a hierarchical model where all DERS subscales loaded on a general emotion dysregulation factor. Internal consistency indicators had adequate values for the general factor and subscales. The positive association between DERS and DASS-21 scores supports the instrument's concurrent validity. Conclusion: These results suggest that the Brazilian version of the DERS is reliable both as a general measure of difficulties in emotion regulation and as a measure of the constituents of this construct. Future research should investigate the psychometric properties of the scale in clinical and nonclinical populations, with equal gender proportions and diverse backgrounds, and preferably employing longitudinal designs.

Resumo

Resumo Introdução: Regulação emocional pode ser definida como o processo pelo qual os indivíduos regulam sua experiência emocional. Tem sido demonstrado que déficits na regulação emocional podem estar associados a vários transtornos psiquiátricos. Nesta linha, a Difficulties in Emotion Regulation Scale (DERS) é um instrumento que foi desenvolvido para acessar dificuldades na regulação emocional. Objetivo: Examinar as propriedades psicométricas de uma versão da DERS adaptada ao português brasileiro. Método: Um total de 377 indivíduos da população geral foram selecionados por conveniência para completar um questionário sociodemográfico, a versão adaptada ao português brasileiro da DERS e a Depression Anxiety Stress Scale (DASS-21). Foram investigadas a estrutura fatorial, confiabilidade e validade concorrente da versão adaptada da DERS. Resultados: A análise fatorial confirmatória replicou a estrutura de seis fatores originalmente proposta para o instrumento e confirmou a aceitabilidade de um modelo hierárquico em que todas as subescalas são carregadas em um fator de desregulação emocional geral. Os indicadores de consistência interna apresentaram valores adequados para o fator geral e subescalas. A associação positiva entre os escores obtidos na DERS e na DASS-21 dá suporte à validade concorrente do instrumento. Conclusão: Esses resultados sugerem que a versão brasileira da DERS é confiável como medida geral de dificuldades na regulação emocional e como medida dos constituintes desta construção. Pesquisas futuras devem investigar as propriedades psicométricas da escala em populações clínicas e não clínicas, com igual proporção de gênero e diversas origens e, de preferência, empregando desenhos longitudinais.
