Brazilian version of the Structured Interview for Disorders of Extreme Stress – Revised (SIDES-R): adaptation and validation process

Résumé 0

"Background: Posttraumatic stress disorder (PTSD) contem- plates 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 charac- terize the behavior and cognitive alterations derived from ex- posure to continuous early life stress. The Structured Inter- view for Disorders of Extreme Stress – Revised (SIDES-R) was developed to investigate and measure DESNOS. Considering the lack of instruments designed to assess DESNOS, espe- cially 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 corres- pondence 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 ver- sion, 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 investi- gation 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."
