The use of protective behavioral strategies (PBS) has been found to attenuate the relationship between alcohol use and related consequences.
The current study examined PBS use as a moderator of the association between alcohol use and consequences in multiple samples (N = 9) of college students with different sample sizes (e.g., ns 125-736). We also examined sex as a moderator of the PBS moderation analyses. Across all samples, we predicted that the use of more PBS would attenuate the use-consequences relation.
In total, 3,524 college students completed online measures of alcohol use, consequences, and PBS use (i.e., PBSS) across two sites. Conclusions/importance: In the analyses, 3 two-way interactions were consistent with the literature (i.e., use-consequences relation weakest among those with high PBS use), 6 were opposite of what was reported in the literature (i.e., use-consequences relation strongest among those with high PBS use), and 39 were not statistically significant. These results corroborate, contradict, and extend the current body of knowledge in the extant alcohol PBS literature. In the examination of three-way interactions in the combined sample, serious harm reduction (SHR) PBS was found to moderate the use-consequences relation among female, but not among male students. Specifically, the use-consequences relation was weakest among female students who used more SHR PBS indicating that SHR PBS may be an important intervention target for female college students. Additional experimental and longitudinal studies are needed to examine the effects of PBS use on the use-consequences relation.
使用保护性行为策略 (PBS) 已被发现可以减轻饮酒与相关后果之间的关系。
本研究在多个样本（N = 125-736）中检验了 PBS 使用作为饮酒与后果之间关联的调节作用，这些样本来自不同的大学生群体。我们还检验了性别作为 PBS 调节分析的调节因素。在所有样本中，我们预测使用更多的 PBS 将减轻使用-后果关系。
共有 3524 名大学生在两个地点通过在线方式完成了饮酒、后果和 PBS 使用（即 PBSS）的测量。
结论/重要性：在分析中，有 3 个双向交互作用与文献一致（即，高 PBS 使用组的使用-后果关系最弱），6 个与文献报告相反（即，高 PBS 使用组的使用-后果关系最强），39 个不具有统计学意义。这些结果与现有的酒精 PBS 文献中的知识相符、相悖和扩展。在对合并样本中的三向交互作用进行检验时，发现严重危害降低 (SHR) PBS 调节了女性学生的使用-后果关系，但对男性学生没有影响。具体来说，在使用 SHR PBS 较多的女性学生中，使用-后果关系最弱，这表明 SHR PBS 可能是女性大学生的一个重要干预目标。需要进行更多的实验和纵向研究来检验 PBS 使用对使用-后果关系的影响。
