Risky sexual behaviors (RSB) frequently occur in the context of alcohol use and are associated with distinct drinking motives among college students. Use of alcohol protective behavioral strategies (PBS) is associated with reductions in alcohol use and related problems, which may extend to alcohol-related RSB. Moreover, as PBS use mediates the relationship between positive reinforcement drinking motives and alcohol-related problems, the same may be true for alcohol-related RSB, specifically. The current study examined whether PBS mediates the relationship between drinking motives and RSB among college students. Participants (N = 2039, 72.8% female, M = 19.79) from ten universities across ten U.S. states completed an online survey assessing past-month drinking motivation, alcohol PBS, alcohol consumption, and RSB. To test study aims, a saturated path model in which drinking motives were modeled as predictors of RSB via PBS use subscales and alcohol consumption was conducted. Several double mediation effects were found, such that stronger endorsement of motives (i.e., social, enhancement, conformity, coping for depression) were associated with lower PBS (particularly manner of drinking and serious harm reduction), which was associated with higher alcohol use, which was associated with higher RSB. Multi-group models found the mediation effects to be gender invariant, although several differences in direct associations were found across genders. For college students high in positive reinforcement motives (i.e., social or enhancement) for drinking, interventions that aim to increase PBS use, specifically related to modifying the manner in which one drinks and avoiding very dangerous consequences, may be effective in reducing alcohol-related RSB.
风险性行为（RSB）常发生在饮酒的背景下，与大学生的不同饮酒动机有关。使用酒精保护性行为策略（PBS）与减少饮酒和相关问题有关，这可能会扩展到与酒精相关的 RSB。此外，由于 PBS 使用在积极强化饮酒动机与酒精相关问题之间起中介作用，同样的情况也可能适用于与酒精相关的 RSB。本研究检验了 PBS 是否在大学生饮酒动机与 RSB 之间起中介作用。参与者（N=2039，72.8%女性，M=19.79）来自美国十个州的十所大学，完成了一项在线调查，评估过去一个月的饮酒动机、酒精 PBS、饮酒量和 RSB。为了检验研究目的，进行了一个饱和路径模型，其中饮酒动机通过 PBS 使用子量表和饮酒量来预测 RSB。发现了几种双重中介效应，例如，更强的动机（即社交、增强、从众、应对抑郁）与更低的 PBS（特别是饮酒方式和严重减少伤害）相关，这与更高的饮酒量相关，而更高的饮酒量与更高的 RSB 相关。多组模型发现，这些中介效应在性别上是不变的，尽管在性别之间发现了一些直接关联的差异。对于那些因社交或增强而饮酒动机较强的大学生来说，旨在增加 PBS 使用的干预措施，特别是与改变饮酒方式和避免非常危险的后果有关的干预措施，可能有助于减少与酒精相关的 RSB。
