目的：本研究的主要目的是提供一个综合评估的基础因素结构的酒精依赖量表（ADS）。次要目标包括评估并发的总ADS和分量表的有效性，从因素分析与酒精依赖相关的变量，并进一步评估两个建议的二分法评分，减少项目ADS措施的有效性。方法：对ADS的反应来自两项大型随机临床试验中符合精神障碍诊断和统计手册第四版酒精依赖标准的参与者：联合收割机（联合药物和行为干预研究; n = 1，335; 69%男性）和Project MATCH（将酒精中毒治疗与客户异质性匹配; n = 1，666; 75%男性）。进行探索性和验证性因素分析，并获得效度系数。结果如下：在样本中，分析支持一个相关的，三因素的解决方案，代表行为控制和酗酒，强迫性饮酒方式，心理知觉和心理物理退缩的损失。ADS与依赖严重程度、饮酒渴望和全神贯注、饮酒诱惑和在高风险复发情况下不饮酒的能力的信心、重度和持续饮酒模式、对酒精相关负面后果的担忧以及对问题饮酒的认识等其他指标显著相关。结论：这些研究结果支持ADS的三因素解决方案及其以可靠和有效的方式评估酒精依赖结构的能力。12项减少的ADS措施（主要反映依赖相关的项目），而不是9项减少的ADS措施（一般过度饮酒项目），提供的有效性系数可比的总，25项ADS。(J.酒精药物研究70：689-699，2009）
Objective: The primary purpose of this study was to provide a comprehensive assessment of the underlying factor structure of the Alcohol Dependence Scale (ADS). Secondary goals included assessing concurrent validity of the total ADS and subscales derived from the factor analyses with variables related to alcohol dependence and further evaluating the validity of two proposed dichotomously scored, reduced-item ADS measures. Method: Responses to the ADS were obtained from participants who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for alcohol dependence in two large randomized clinical trials: COMBINE (Combining Medications and Behavioral Interventions Study; n = 1,335; 69% male) and Project MATCH (Matching Alcoholism Treatments to Client Heterogeneity; n = 1,666; 75% male). Both exploratory and confirmatory factor analyses were conducted, and validity coefficients were obtained. Results: Across samples, analyses Supported a correlated, three-factor solution representing loss of behavioral control and heavy drinking, obsessive-compulsive drinking style, and psychoperceptual and psychophysical withdrawal. The ADS was significantly related to other measures of severity of dependence, craving for and preoccupation with drinking, temptation to drink and confidence in the ability to not drink in high-risk relapse situations, heavy and sustained drinking patterns, concerns about negative alcohol-related consequences, and awareness of problematic drinking. Conclusions: These findings support a three-factor solution for the ADS and its ability to assess the construct of alcohol dependence in a reliable and valid manner. The 12-item reduced ADS measure (reflecting mostly dependence-related items), as opposed to the 9-item reduced ADS measure (generally excessive drinking items), provided validity coefficients comparable to the total, 25-item ADS.
