Factor Structure and Predictive Validity of the Obsessive Compulsive Drinking Scale

Abstract

The three OCDS factors are easily estimated with the summated scoring approach, and the resulting subscales appear to be internally consistent and distinctive. Moreover, the group differentiation capability and predictive utility of the subscale scores suggest that they might be useful as either predictor or outcome variables in alcoholism treatment trials. The duration of time for which a given OCDS assessment maintains its predictive utility awaits further confirmation.
