The Obsessive Compulsive Drinking Scale (OCDS) measures alcohol craving but shows limited predictive validity for future drinking. Only the alcohol consumption factor effectively predicted drinking behavior post-treatment.

Area of Science:

  • Psychiatry
  • Addiction Medicine
  • Psychometrics

Background:

  • The Obsessive Compulsive Drinking Scale (OCDS) is a self-report measure designed to assess alcohol-related craving.
  • It was hypothesized that the OCDS could indicate the severity of alcohol dependence and predict future drinking patterns.

Purpose of the Study:

  • To evaluate the factor structure of the OCDS.
  • To assess the concurrent, construct, and predictive validity of the OCDS in individuals with alcohol dependence.

Main Methods:

  • 127 alcohol-dependent subjects participated in a 12-week outpatient pharmacotherapy trial.
  • Data on drinking desire and behavior were collected during treatment and a 3-month follow-up.

Main Results:

Related Experiment Videos

  • Principal components analysis revealed a three-factor structure for the OCDS: obsessions, drinking control/consequences, and alcohol consumption.
  • The OCDS demonstrated concurrent and discriminant validity.
  • The total OCDS score had limited predictive validity for post-treatment drinking; only the alcohol consumption factor was a significant predictor.

    • Conclusions:

    • The OCDS effectively captures aspects of drinking behavior but does not appear to be a comprehensive measure of overall alcohol-related illness.
    • The OCDS's utility in alcoholism treatment outcome studies needs further clarification, particularly regarding its predictive capabilities beyond specific behavioral components.
