The Spanish alcohol use disorder and associated disabilities interview schedule (AUDADIS):: Reliability and concordance with clinical diagnoses in a Hispanic population

Objective: The study reports the process of translation into Spanish and adaptation to the Hispanic culture of the Alcohol Use Disorder and Associated Disabilities Schedule (AUDADIS). This instrument is a structured diagnostic interview schedule specifically developed for the assessment of substance-related disorders and their comorbid disorders and disabilities, Method: A random sample (N = 169) of adults from a primary health care clinic in Puerto Rico was selected. The test-retest reliability of the instrument was examined across time and across interviewers, and the validity was assessed by comparing computer-derived diagnoses obtained through the administration of lay interviewers with best estimate diagnoses given by board-certified psychiatrists. Results: For most diagnoses and symptoms studied, as well as for most of the alcohol consumption measures, the test-retest reliability of the Spanish AUDADIS was consistent with results reported in other national and international studies using this instrument. Good to excellent test-retest reliability was obtained for the diagnoses of alcohol dependence and major depression. Similarly, good to excellent agreement was obtained between the lay administered AUDADIS and best estimate diagnoses for most diagnostic categories, with the exception of dysthymia. As in other studies, the reliability and validity of the substance abuse category was poor. When agreement for this category was estimated independent of lifetime dependence, both the reliability and validity coefficients were considerably improved. Conclusions: The Spanish AUDADIS generally demonstrates good to excellent levels of reliability and validity that are comparable to findings reported for this instrument in other national and international studies.
