The Obsessive Compulsive Drinking Scale [OCDS; Anton et al., Alcohol Clin Exp Res 19 (1995), 92] is the most widely used measure of alcohol craving. There are no studies which comprehensively investigate the construct and concurrent validity of the OCDS in a severe alcohol dependent population.
Three hundred and seventy alcohol-dependent patients were referred to a hospital-based alcohol treatment program. All participants completed the OCDS, the Alcohol Use Disorders Identification Test [AUDIT; Saunders et al., Addiction 88 (1993), 791] and provided demographic and alcohol consumption data.
The sample was randomly split into 2. Exploratory factor analysis and confirmatory factor analysis were conducted on these subsamples. Both analyses identified a 4-factor solution (compulsions, interference, obsessions and resisting obsessions). All factors showed sound internal consistency. Neither the factor scores nor the total OCDS score was related to baseline alcohol problems (AUDIT) or consumption.
There was some support for the construct validity of the OCDS in this clinical group. Concurrent validity of the scale was not supported by these cross-sectional data. Future research should examine the predictive utility of the OCDS over time.
强迫性饮酒量表[OCDS；Anton等人，《酒精临床与实验研究》19（1995），92]是使用最广泛的酒精渴望测量工具。尚无研究全面调查OCDS在重度酒精依赖人群中的结构效度和同时效度。
370名酒精依赖患者被转介至一家基于医院的酒精治疗项目。所有参与者均完成了OCDS、酒精使用障碍识别测试[AUDIT；Saunders等人，《成瘾》88（1993），791]，并提供了人口统计学和酒精消费数据。
样本被随机分为两组。对这些子样本进行了探索性因素分析和验证性因素分析。两项分析均确定了一个四因素解决方案（强迫行为、干扰、强迫观念和抵抗强迫观念）。所有因素均显示出良好的内部一致性。因素得分和OCDS总分均与基线酒精问题（AUDIT）或消费量无关。
该临床组对OCDS的结构效度有一定支持。这些横断面数据不支持该量表的同时效度。未来的研究应考察OCDS随时间的预测效用。
