College student drinkers (N = 314) participated in a health survey in which they (a) completed an alcohol-related memory association task (expectancy accessibility measure), (b) rated their positive expectancies about alcohol use (expectancy strength measure), and (c) reported their level of alcohol involvement. Hierarchical regression analyses showed that both expectancy accessibility and expectancy strength predicted frequency of alcohol use and alcohol-related problems. Moreover, moderational analyses showed that the association between expectancy strength and frequency of alcohol use was greater for those who generated more alcohol responses on the expectancy association task. These findings suggest that the outcome association measure and Likert scale ratings of expectancies may assess distinct properties of expectancy representations, which may have independent and interactive effects on different aspects of drinking behavior.
大学生饮酒者（N = 314）参与了一项健康调查，在该调查中，他们（a）完成了一项与酒精相关的记忆联想任务（预期可及性测量），（b）对饮酒的积极预期进行评分（预期强度测量），以及（c）报告他们的酒精参与程度。分层回归分析表明，预期可及性和预期强度都能预测饮酒频率和与酒精相关的问题。此外，调节分析表明，对于那些在预期联想任务中产生更多酒精相关反应的人来说，预期强度与饮酒频率之间的关联更大。这些发现表明，结果联想测量和预期的李克特量表评分可能评估了预期表征的不同属性，这些属性可能对饮酒行为的不同方面产生独立和交互作用。
