Drinking motives are robustly related to alcohol use behavior from adolescence through young adulthood. Yet, examination of changes in motives during the first year of college, a transitional time associated with both onset of and increases in heavy drinking has been understudied. We examined (a) whether drinking motives change, (b) time-varying effects of motives on alcohol use and consequences, and (c) change in the strength of the association between motives and use and motives and consequences over the first year of college. A sample of 121 heavy drinking first-year students (50% female, 58% Caucasian) completed three assessments (baseline, 3 months, 6 months). Endorsement of social motives declined from 0 to 3 months, while endorsement of coping, enhancement, and conformity motives declined from 3 to 6 months. Social motives were positively associated with alcohol use and consequences across assessments. When motive × time interactions were tested in separate models, the strength of effects of coping motives on drinks per week increased from 0 to 3 months. The strength of the effect of coping and conformity motives on consequences increased from 0 to 3 months and then decreased from 3 to 6 months. Identifying how drinking motives evolve and relate to trajectories of alcohol use may help to understand the development of risky drinking behavior and inform intervention efforts.
饮酒动机与从青春期到青年期的酒精使用行为密切相关。然而，大学第一年这一与大量饮酒的开始和增加都相关的过渡时期内动机变化的研究却很少。我们研究了：（a）饮酒动机是否会改变；（b）动机对酒精使用及后果的随时间变化的影响；（c）在大学第一年中动机与使用之间以及动机与后果之间关联强度的变化。121名大量饮酒的大学一年级学生样本（50%为女性，58%为白种人）完成了三次评估（基线、3个月、6个月）。社交动机的认可度从0到3个月下降，而应对、增强和从众动机的认可度从3到6个月下降。在各次评估中，社交动机与酒精使用及后果呈正相关。当在单独模型中检验动机×时间的交互作用时，应对动机对每周饮酒量的影响强度从0到3个月增加。应对和从众动机对后果的影响强度从0到3个月增加，然后从3到6个月下降。确定饮酒动机如何演变以及与酒精使用轨迹的关系，可能有助于理解危险饮酒行为的发展并为干预措施提供依据。
