[Adaptation and validation of the Alcohol Use Disorders Identification Test (AUDIT) for a river population in the Brazilian Amazon].

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.
