Although the expectancies component of the Comprehensive Effects of Alcohol Questionnaire has previously been shown to be factorially valid, the factor structure of its valuations component has not previously been examined. The aims of this paper were: (i) to replicate the factor structure of the expectancies items; (ii) to explore the factor structure of the valuations items; and (iii) to investigate the utility of using the Comprehensive Effects of Alcohol Questionnaire to predict drinking behavior. The questionnaire was administered to 1004 university students along with measures of quantity and frequency of alcohol consumption. Fromme, Stroot, and Kaplan's (1993) factor structure of the expectancies scales was replicated. The factor structures of the negative valuations scales were characterized by 2 rather than 3 factors. Negative expectancies improved upon the prediction of drinking quantity and frequency over-and-above positive expectancies, and valuations further improved prediction over-and-above expectancies. Theoretical and clinical implications are discussed.
尽管先前已证明酒精问卷综合效应的预期成分具有因子效度，但此前尚未对其评价成分的因子结构进行检验。本文的目的是：（i）复制预期项目的因子结构；（ii）探索评价项目的因子结构；（iii）研究使用酒精问卷综合效应来预测饮酒行为的效用。该问卷被施用于1004名大学生，并同时测量了酒精消费的量和频率。弗罗梅、斯特鲁特和卡普兰（1993年）预期量表的因子结构得到了复制。负面评价量表的因子结构由2个而非3个因子表征。负面预期在预测饮酒量和频率方面比正面预期有改进，而评价在预期之上进一步提高了预测效果。文中讨论了理论和临床意义。
