The present study sought to identify motivational profiles for responsible drinking from a self-determination theory (SDT) perspective among college students. We used data from 507 students who reported drinking alcohol at least once in the past 3 months that were recruited from a random sample of undergraduate students at a Southwestern university. Participants completed an online survey that included measures assessing amotivation, external regulation, introjected regulation, and autonomous motivation for responsible drinking as well as other SDT constructs, alcohol protective behavioral strategies (PBS), and alcohol use/problems. A latent profile analysis suggested that a 3-class solution was optimal: a “High Quality” class (i.e., relatively high on introjected regulation and autonomous motivation but relatively low on all other types of motivation), a “High Quantity” class (i.e., relatively high on all types of motivation), and a “Low Quantity” class (i.e., relatively low on all types of motivation). The High Quality class reported the highest level of psychological need satisfaction and dispositional autonomy, followed by the High Quantity class, with the Low Quantity class reporting the lowest levels. The High Quality class reported more frequent use of serious harm reduction PBS than the High Quantity class. Generally, both the High Quality and High Quantity classes reported more frequent use of all types of PBS and less alcohol use/problems than the Low Quantity class. These results provide initial support for different profiles of motivations based on SDT for responsible drinking. Potential implications for alcohol interventions among college students are discussed.

本研究试图从大学生的自我决定理论 (SDT) 的角度确定负责任饮酒的动机特征。我们使用了 507 名报告在过去 3 个月内至少饮酒一次的学生的数据，这些学生是从西南大学的本科生随机样本中招募的。参与者完成了一项在线调查，其中包括评估动机、外部调节、内摄调节和负责任饮酒的自主动机以及其他 SDT 结构、酒精保护行为策略 (PBS) 和酒精使用/问题的措施。潜在剖面分析表明 3 类解决方案是最佳的：“高质量”类（即，内射调节和自主动机相对较高，但在所有其他类型的动机上相对较低），“高数量”类别（即在所有类型的动机上相对较高）和“低数量”类别（即，在所有其他类型的动机上相对较低）所有类型的动机）。高质量类报告了最高水平的心理需求满足和处置自主性，其次是高数量类，低数量类报告了最低水平。高质量类报告更频繁地使用 低数量类报告最低水平。高质量类报告更频繁地使用 低数量类报告最低水平。高质量类报告更频繁地使用PBS 比 High Quantity 类的严重危害减少。一般而言，与低数量类别相比，高质量和高数量类别都报告更频繁地使用所有类型的 PBS 以及更少的酒精使用/问题。这些结果为基于 SDT 的负责任饮酒的不同动机提供了初步支持。讨论了大学生酒精干预的潜在影响。
