Adaptação e validação do Alcohol Use Disorder Identification Test (AUDIT) para população ribeirinha do interior da Amazônia, Brasil

Abstract

The objective of this study was to validate the Alcohol Use Disorders Identification Test (AUDIT) for a river population in the Brazilian Amazon. The original English version of AUDIT was translated into Portuguese, using the procedure recommended by the World Health Organization. The text was then back-translated and submitted to a native English translator, who approved the translation. AUDIT was administered to 361 inhabitants for a total of three times in two weeks. Data were analyzed for test/retest reliability and internal consistency. Cronbach's alpha was 0.87 at the first interview, 0.87 at the second, and 0.86 at the third. Test/retest reliability assessed via the intra-class correlation coefficient for the total AUDIT scale was 0.93. Area under ROC was 0.805 for a cutoff of seven (sensitivity 76.4%; specificity 75%). The validated AUDIT proved to be internally consistent and stable over time, but requires further investigation of its psychometric properties.
