Abstract

Background: Obsessive thoughts and compulsive drinking behaviors have been proposed as key factors associated with the loss of control over alcohol consumption experienced by alcohol-dependent patients. The self-report 14-item Obsessive Compulsive Drinking Scale (OCDS; Anton et al., 1995) was designed in order to rate these features. Methods: A Spanish-translated version of the OCDS was applied to a group of 159 alcohol-dependent subjects while in abstinence, and data were analyzed in order to evaluate the factor structure and concurrent validity of the scale. Results: Several solutions were explored after applying the principal factor analysis to the data. The most plausible result was obtained after excluding the items on quantity and frequency of drinking. This model explaining 56.9% of the variance included 2 factors: obsessive thoughts related to drinking and interference/behaviors related to drinking. Additionally, OCDS scores were significantly correlated with measures for the Alcohol Dependence Scale, number of DSM-IV criteria met for alcohol dependence as well as the number of days in a week engaged in heavy drinking, indicating concurrent validity. Conclusions: Our results support the use of OCDS as a valid self-rated instrument that can be broadly applied in research and treatment settings. However, its current version includes questions that may not represent the core concept of craving. The abridged 12-item version of the scale (excluding the items on drinking habits) maintains good psychometrics features and seems to be adequate when different cognitive and behavioral dimensions are explored.
