背景资料：这项研究介绍了宾夕法尼亚大学酒精渴求量表（PACS），该量表已在宾夕法尼亚大学治疗研究中心的几项临床试验中使用。PACS是一项五项自我报告措施，包括有关渴望的频率，强度和持续时间的问题，抵抗饮酒的能力，并要求对前一周的酒精渴望进行总体评级。每个问题的范围从0到6。方法：为了检查问卷的心理测量学特性，我们从147名参与9个月的联合纳曲酮（100 mg/天）/心理治疗试验的个体中取样。心理治疗包括每周一次的护士管理的药物依从性和支持性治疗。通过对试验第3-12周酒精复发研究第2周期间的渴望进行逻辑回归分析，证明了预测有效性。PACS的结构效度通过其与两种常用的评估渴望的措施，强迫性饮酒量表和酒精冲动问卷的收敛性得到证明。PACS评分与其他几种非渴求性自我报告指标之间缺乏相关性，表明PACS也具有良好的判别效度。进一步分析显示，在3- 12周内复发和未复发的受试者在最初3周内的渴求评分差异有统计学意义。结论：PACS是一种可靠有效的酒精渴求测量方法，可以预测哪些个体有随后复发的风险。
Background: This study introduces the Penn Alcohol Craving Scale (PACS), which has been used in several clinical trials at the University of Pennsylvania's Treatment Research Center. The PACS is a five-item, self-report measure that includes questions about the frequency, intensity, and duration of craving, the ability to resist drinking, and asks for an overall rating of craving for alcohol for the previous week. Each question is scaled from 0 to 6.Methods: To examine the questionnaire's psychometric properties, we sampled responses from 147 individuals participating in a 9-month combined natrexone (100 mg/day)/psychotherapy trial. The psychotherapy consisted of weekly sessions of nurse-administered medication compliance and supportive treatment.Results: The PACS proved to have excellent internal consistency. Predictive validity was demonstrated via a logistic regression analysis of craving during the 2nd week of the study on alcohol relapse during weeks 3-12 of the trial. Construct validity of the PACS was demonstrated via its convergence with two commonly used measures for assessing craving, the Obsessive Compulsive Drinking Scale and the Alcohol Urge Questionnaire. Lack of correlation between PACS scores and several other noncraving, self-report measures indicates that the PACS also had good discriminant validity. Additional analyses revealed that there were significant differences in craving scores during the initial 3 weeks of the trial among those who did and those who did not relapse during weeks 3-12.Conclusion: The PACS is a reliable and valid measure of alcohol craving and can predict which individuals are at risk for subsequent relapse.
