目的：本研究的目的是检验酒精预期与酒精使用（饮酒频率、通常数量、五次以上饮酒）之间的联系是否由饮酒动机介导。方法：基于瑞士全国代表性的5,616名八、九、十年级学生（51%为女生，平均[SD]年龄= 15.1[1.0]岁）的线性结构方程模型进行估计。结果：在大多数情况下，出现了完美的调解。尽管在多变量模型中，所有的期望和动机维度都与所有的酒精使用措施相关，但在多变量模型中，期望联系减少到零，而动机联系基本保持不变。一个例外是紧张缓解预期量表，它包括了与饮酒有关的问题应对之外的其他方面，即使在应对动机受到控制的情况下。结论：鉴于不同酒精预期、饮酒动机和酒精使用措施的结果的一致性，本研究为支持酒精使用动机模型的一个基本假设提供了证据：饮酒动机是导致酒精使用的最直接因素。它们是更多远端影响（如酒精预期）被介导的门户。
Objective: The purpose of this study was to test whether the link between alcohol expectancies and alcohol use (drinking frequency, usual quantity, five-plus drinking) is mediated by drinking motives.Method: Linear structural equation models were estimated based on a nationally representative sample of 5,616 8th, 9th, and 10th graders in Switzerland (51% female; mean [SD] age = 15.1 [1.0] years).Results: In most cases, a perfect mediation occurred. Although all expectancy and motive dimensions were related to all alcohol-use measures in multivariate models, the expectancy link in multiple multivariate models was reduced to zero, whereas the motive link remained basically the same. One exception was the Tension Reduction Expectancy scale, which included aspects other than problem coping that were still related to alcohol consumption, even when coping motives were controlled for.Conclusions: Given the consistency of the results across different alcohol expectancies, drinking motives, and alcohol-use measures, the present study provides evidence to Support one basic assumption of the motivational model of alcohol use: Drinking motives are the most proximate factor that precedes alcohol use. They are the gateway through which more distal influences (e.g., alcohol expectancies) are mediated.
