BACKGROUND
College-related alcohol beliefs, or beliefs that drinking alcohol is central to the college experience, have been shown to robustly predict alcohol-related outcomes among college students. Given the strength of these associations, it is imperative to understand more proximal factors (i.e., closer in a causal chain leading to alcohol-related outcomes) that can explain these associations.
OBJECTIVES
The current research examined alcohol protective behavioral strategies (PBS) as a potential mediator of the association between college-related alcohol beliefs and alcohol outcomes among college student drinkers.
METHOD
Participants were undergraduate students from a large southeastern university (Sample 1; n = 561) and a large southwestern university (Sample 2; n = 563) in the United States that consumed alcohol at least once in the previous month.
RESULTS
Path analysis was conducted examining the concurrent associations between college-related alcohol beliefs, PBS use (both as a single facet and multidimensionally), alcohol consumption, and alcohol-related consequences (i.e., double mediation). In both samples, there was a significant double-mediated association that suggested that higher college-related alcohol beliefs is associated with lower PBS use (single facet), which is associated with higher alcohol consumption and alcohol-related consequences. Multidimensionally, only one double-mediation effect (in Sample 2 only) was significant (i.e., college-related alcohol beliefs → manner of drinking PBS → alcohol consumption → alcohol-related consequences). Conclusions/Importance: These results suggest that targeting these college-related alcohol beliefs as well as PBS use are promising targets for college alcohol interventions. Limitations and future directions are discussed.
背景
与大学相关的饮酒观念，即认为饮酒是大学生活的核心，已被证明能有力地预测大学生与酒精相关的行为结果。鉴于这些关联的强度，有必要了解更多能解释这些关联的近端因素（即在导致与酒精相关结果的因果链中更接近的因素）。
目的
当前研究考察了酒精保护行为策略（PBS）作为大学生饮酒者中与大学相关的饮酒观念和酒精行为结果之间关联的潜在中介因素。
方法
参与者是来自美国东南部一所大型大学（样本1；n = 561）和西南部一所大型大学（样本2；n = 563）的本科生，他们在前一个月至少饮酒一次。
结果
进行了路径分析，以检验与大学相关的饮酒观念、PBS使用（单一方面和多维度）、酒精消费以及与酒精相关后果（即双重中介）之间的同时关联。在两个样本中，均存在显著的双重中介关联，表明较高的与大学相关的饮酒观念与较低的PBS使用（单一方面）相关，而较低的PBS使用又与较高的酒精消费和与酒精相关的后果相关。从多维度来看，只有一个双重中介效应（仅在样本2中）显著（即与大学相关的饮酒观念→饮酒方式的PBS→酒精消费→与酒精相关的后果）。结论/重要性：这些结果表明，针对这些与大学相关的饮酒观念以及PBS使用是大学酒精干预的有前景的目标。讨论了研究的局限性和未来方向。
