Measuring alcohol consumption: confirmatory factor analysis of The Alcohol Use Disorder Identification Test (AUDIT)

This study aims to evaluate the adequacy of uni and multi-factorial models of AUDIT, as well as to verify its convergent and criterion validity. Participants consisted in 386 people from the general population with average age of 27.7 years (SD=10.5). In addition to AUDIT , the participants responded to two others correlated instruments - CAGE and EAFUA - and to biosocialdemographic questions. The confirmatory factor analysis indicated the adequacy of the model of three factors, with goodness of fit indexes (χ²/gl=63,29, CFI=0,98, AGFI=0,98 e RMSEA=0,05) statistically higher than the structure of one and two factors. Finally, resorting to Pearson's r correlations and the comparison of means, both convergent and criterion validity of AUDIT were confirmed, attesting its proposal of measuring alcohol consumption and demonstrating its applicability in the screening of problem drinkers.
