Alcohol Use Disorder Identification Test (AUDIT): explorando seus parametros psicométricos

objective: this study aimed to know evidences of validity and reliability of the alcohol use disorder identification test (audit). methods: for this purpose, we considered 547 college students from fortaleza (ce) with a mean age of 21.6 years (sd = 4.86, varying from 18 to 53), mostly male (51.5%), single (91.4%) and catholic (62.5%). the participants answered the audit and demographic questions. looking to know audit's factorial structure, we carried out a principal component analysis. additionally, in order to evaluate its reliability, we calculated cronbach's alpha (internal consistency), pearson correlation r and intraclass coefficient correlation - icc (test-retest). also, descriptive statistics were evaluated. results: according to the principal component analysis using oblimin rotation, the bifactorial structure of the audit proved to be consistent, once all items showed satisfactory saturations exceeding |0.40|, with the first factor explaining 47.5% of the total variance with alpha of 0.84 and factor 2 explaining 11.6% of the total variance with alpha of 0.69. the results of the test-retest showed strong correlation between data obtained in the first (t1) and in the second (t2) applications (rtt = 0.94, p < 0.01), with no significant difference between the means in both applications (mt1 = 0.37, sd = 0.49, = 0.34 mt2, dp2 = 0.47, p > 0.05) with satisfactory icc (0.96). conclusions: the findings support the psychometric adequacy of the audit, with the exploratory factor analysis pointing as more satisfactory the structure with two factors, and also showing its good temporal stability.
