The Obsessive Compulsive Drinking Scale (OCDS), a 14-item, self-report questionnaire, was developed to measure alcohol-related craving. The OCDS may provide a measure of the state of illness among alcohol-dependent individuals and may have value in predicting subsequent drinking behavior. The present study was conducted to evaluate the factor structure and the concurrent, construct, and predictive validity of the OCDS.
Data on desire to drink and on drinking behavior were obtained from 127 alcohol-dependent subjects who participated in a 12-week outpatient pharmacotherapy trial and a 3-month posttreatment follow-up.
Principal components analysis of the OCDS indicated that three factors best described its structure: obsessions, drinking control and consequences, and alcohol consumption. Data also supported the concurrent and discriminant validity of the OCDS. However, the OCDS total score showed limited validity in predicting drinking during a posttreatment follow-up period. Furthermore, the only empirically derived factor that predicted drinking during this period was the alcohol consumption factor.
As might be expected, the OCDS questions on drinking behavior predict subsequent drinking behavior. However, the instrument does not appear to provide a general measure of alcohol-related illness. The utility of the OCDS in studies of alcoholism treatment outcome requires clearer definition.
强迫性饮酒量表（OCDS）是一份包含14个条目的自陈式问卷，旨在测量与酒精相关的渴望程度。OCDS可能为酒精依赖个体的疾病状态提供一种衡量方式，并且在预测后续饮酒行为方面可能具有价值。本研究旨在评估OCDS的因子结构以及同时效度、结构效度和预测效度。
关于饮酒欲望和饮酒行为的数据来自127名酒精依赖受试者，他们参与了一项为期12周的门诊药物治疗试验以及为期3个月的治疗后随访。
对OCDS进行主成分分析表明，三个因子最能描述其结构：强迫观念、饮酒控制与后果以及酒精摄入量。数据还支持了OCDS的同时效度和区分效度。然而，OCDS总分在预测治疗后随访期间的饮酒情况时效度有限。此外，在此期间唯一经实证得出的能够预测饮酒的因子是酒精摄入量因子。
正如预期的那样，OCDS中关于饮酒行为的问题能够预测后续饮酒行为。然而，该工具似乎并不能提供一种对酒精相关疾病的综合衡量方式。OCDS在酒精中毒治疗结果研究中的效用需要更明确的界定。
