The aim of this work is to present the adaptation and study of the psychometric properties of the Brief Young Adult Alcohol Consequences Questionnaire (B-YAACQ) in a sample of 323 Spanish Psychology students, of which 74.3% are women. The items were back-translated following the International Test Commission (ITC) standards, and a confirmatory factor analysis (CFA) was conducted by means of the Mplus program, using the Weighted Least Squares Means and Variances adjusted (WLSMV) extraction method and the polychoric correlation matrix. Goodness of fit of the CFA showed satisfactory results on the one-dimensional model, and all the factor loadings were adequate and statistically significant. The internal consistency and the homogeneity indices of the instrument are good. The questionnaire also presents good evidence of criterion validity and differential validity. With this instrument, the consequences derived from alcohol consumption in Spanish young people could be evaluated with precision, which will allow to propose more adjusted interventions to the real needs to prevent alcohol consumption.
