“…However, there is a clear necessity for test-retest and interrater reliability studies and further validation studies in order to define the best cutoff points for each population and in different countries, languages and cultures. In particular, it is important to measure the instrument's sensitivity, specificity, and positive and negative predictive validity having adequate diagnostic instruments as comparative measures (Hodgson et al, 2002), as is the case of the structured clinical interview for diagnosis -clinical version (SCID-CV) or the composite international diagnostic interview (CIDI), which has not been done so far.Thus, this study aimed at evaluating the FAST psychometric qualities and at comparing them with those of the AUDIT in the screening of alcohol abuse and dependence in three clinical and nonclinical samples of Brazilian adults, using the Brazilian version of the SCID-IV (Del-Ben, Vilela, Crippa, Labate, and Zuardi, 2001) as the comparative diagnostic measure.
