This study examined protective behavioral strategies (PBS) as a potential mediator and moderator of the relationship between self-regulation and alcohol-related consequences. Participants were 249 first-year undergraduate men and women. The use of PBS partially mediated the relationship between self-regulation and alcohol-related problems (i.e., supporting the "self-control equals drinking control" hypothesis). However, use of PBS appeared more important for those with poorer self-regulation abilities (supporting the "PBS protect the impaired" hypothesis). Because both mediation and moderation were supported, a moderated mediation model was tested. The moderated mediation model demonstrated that the negative relationship between self-regulation and alcohol-related consequences could be explained by use of PBS for individuals with poor-to-average self-regulation but not for individuals with above-average, self-regulation abilities. Implications of the study's findings are discussed.
本研究考察了保护性行为策略 (PBS) 作为自我调节与酒精相关后果之间关系的潜在中介和调节因素。参与者为 249 名一年级本科男女学生。PBS 的使用部分中介了自我调节与酒精相关问题之间的关系（即支持“自我控制等于饮酒控制”假设）。然而，对于自我调节能力较差的人来说，使用 PBS 似乎更为重要（支持“PBS 保护受损者”假设）。由于同时支持中介和调节，因此测试了一个调节中介模型。该调节中介模型表明，对于自我调节能力差到中等的个体，自我调节与酒精相关后果之间的负相关关系可以通过使用 PBS 来解释，但对于自我调节能力高于平均水平的个体则不能。讨论了研究结果的意义。
