Abstract

BACKGROUND: Posttraumatic stress disorder (PTSD) contemplates the impact of acute traumatic events, but the literature indicates that this is not true for chronic exposure to stress. In this sense, the category disorders of extreme stress not otherwise specified (DESNOS) has been proposed to characterize the behavior and cognitive alterations derived from exposure to continuous early life stress. The Structured Interview for Disorders of Extreme Stress - Revised (SIDES-R) was developed to investigate and measure DESNOS. Considering the lack of instruments designed to assess DESNOS, especially in Brazil, the aim of this study was to translate, adapt, and validate the contents of SIDES-R to Brazilian Portuguese (SIDES-R-BR). METHOD: The original interview was subjected to translation, back-translation, semantic equivalence and conceptual correspondence analyses by naive and specialized judges, respectively, an acceptability trial, and inter-rater validity analysis. RESULTS: The interview underwent semantic and structural adaptations considering the Brazilian culture. The final version, SIDES-R-BR, showed a mean understanding score of 4.98 on a 5-point verbal rating scale, in addition to a kappa coefficient of 0.853. CONCLUSION: SIDES-R-BR may be a useful tool in the investigation of DESNOS and contributes a valuable input to clinical research in Brazil. The availability of the instrument allows to test symptoms with adequate reliability, as verified by the kappa coefficient and translation steps.

Resumo

INTRODUÇÃO: O transtorno do estresse pós-traumático (posttraumatic stress disorder, PTSD) contempla o impacto de eventos traumáticos agudos, mas a literatura indica que o mesmo não se aplica a exposição crônica ao estresse. Nesse sentido, foi proposta a categoria transtornos de estresse extremo não especificados (disorders of extreme stress not otherwise specified, DESNOS). Com o objetivo de investigar e medir as alterações comportamentais e cognitivas relacionadas ao diagnóstico de DESNOS, foi desenvolvida a Structured Interview for Disorders of Extreme Stress - Revised (SIDES-R). Considerando a falta de instrumentos construídos para avaliar DESNOS, especialmente no Brasil, o objetivo deste estudo foi traduzir, adaptar e validar os conteúdos da SIDES-R para português brasileiro (SIDES-R-BR). MÉTODO: A entrevista original foi submetida a tradução, retrotradução, análise de equivalência semântica e correspondência conceitual por avaliadores leigos e especializados, respectivamente. Foi realizado teste de aceitabilidade e análise de validade interavaliadores. RESULTADOS: A entrevista passou por adaptações semânticas e estruturais considerando a cultura brasileira. A versão final, SIDES-R-BR, demonstrou um escore médio de compreensão de 4,98 em uma escala de avaliação verbal de 5 pontos, além de um coeficiente de kappa de 0,853. CONCLUSÃO: O SIDES-R-BR pode ser uma ferramenta útil na investigação de DESNOS e contribui com um input valioso para a pesquisa clínica no Brasil. A disponibilidade do instrumento permite testar sintomas com confiabilidade adequada, conforme verificado por meio do coeficiente de kappa e etapas de tradução.
