Analyses focus on whether self-reported reasons for drinking alcohol change in their associations with high-intensity drinking across the transition to adulthood.
Self-report data on high-intensity drinking (10+ drinks) collected from the national Monitoring the Future study in 2005 to 2014 from those ages 18-26 were used (N = 2,664 [60% women] for all drinkers and 1,377 for heavy episodic [5+] drinkers; up to 6,541 person-waves). Time-varying effect modeling examined changes in the direction and magnitude of associations between eight reasons for drinking and high-intensity alcohol use across continuous age.
Four reasons to drink showed quite stable associations with high-intensity drinking across age: drinking to get away from problems, to get high, to relax, and to sleep. Associations between two reasons and high-intensity drinking decreased with age: anger/frustration and to have a good time. The association between drinking because of boredom and high-intensity drinking increased with age. Drinking because it tastes good had a weak association with high-intensity drinking. Among heavy episodic drinkers, reasons for use also differentiated high-intensity drinking, with two exceptions: drinking to have a good time and to relax did not distinguish drinking 10+ drinks from drinking 5-9 drinks.
Reasons for drinking are differentially associated with high-intensity drinking, compared with any other drinking and compared with lower intensity heavy drinking, across age during the transition to adulthood. Intervention programs seeking to mitigate alcohol-related harms should focus on reasons for use when they are the most developmentally salient.
分析重点在于，在向成年期过渡的过程中，自我报告的饮酒原因与高强度饮酒之间的关联是否会发生变化。
使用从2005年至2014年全国性的“未来监测”研究中收集的18至26岁人群关于高强度饮酒（10杯及以上）的自我报告数据（所有饮酒者N = 2664人[60%为女性]，重度偶发性[5杯及以上]饮酒者1377人；多达6541人次）。时变效应模型研究了八个饮酒原因与连续年龄阶段的高强度酒精使用之间关联的方向和强度变化。
四个饮酒原因在各年龄段与高强度饮酒的关联相当稳定：借酒消愁、寻求刺激、放松和助眠。两个原因与高强度饮酒的关联随年龄增长而减弱：愤怒/沮丧以及享受时光。因无聊而饮酒与高强度饮酒的关联随年龄增长而增强。因味道好而饮酒与高强度饮酒的关联较弱。在重度偶发性饮酒者中，饮酒原因也能区分高强度饮酒情况，但有两个例外：为了享受时光和放松而饮酒并不能区分饮用10杯及以上与饮用5 - 9杯的情况。
在向成年期过渡的过程中，与其他任何饮酒情况以及较低强度的重度饮酒相比，饮酒原因与高强度饮酒的关联存在差异。旨在减轻与酒精相关危害的干预项目应在饮酒原因最具发展显著性时予以关注。
