The co-occurence of posttraumatic stress (PTS) and risky drinking has been demonstrated in diverse populations, including college students. However, the mechanisms underlying this co-occurrence, as well as the protective factors that may reduce risky drinking among trauma-exposed college students have yet to be fully understood in the literature.
The present study builds upon self-regulation theories and previous empirical work to determine whether the effects of PTS and coping flexibility on risky drinking were mediated by delay of gratification among trauma-exposed college students. In addition, the potential moderating effect of gender on these relationships was examined.
Participants included 624 trauma-exposed college students (68.4% female) attending a public university in the southeast region of the United States. Data were collected through an online survey. The hypothesized model was examined using a multigroup structural equation modeling approach.
As hypothesized, PTS had a significant, positive indirect effect on risky drinking through delay of gratification; however, the effect of PTS on delay of gratification was stronger for males than for females. Results also indicated that the indirect effect of coping flexibility on risky drinking through delay of gratification was significant and negative for males and females. Conclusions/Importance: The findings of this study suggest that delay of gratification might be an important mechanism underlying the co-occurrence of PTS and risky drinking. In addition, our results highlight the potential benefits of coping flexibility for college students coping with PTS.
创伤后应激（PTS）与危险饮酒的共同出现已在包括大学生在内的不同人群中得到证实。然而，这种共同出现的潜在机制，以及可能降低遭受创伤的大学生危险饮酒行为的保护因素，在文献中尚未得到充分理解。
本研究基于自我调节理论和先前的实证研究，以确定在遭受创伤的大学生中，PTS和应对灵活性对危险饮酒的影响是否通过延迟满足来介导。此外，还考察了性别对这些关系的潜在调节作用。
参与者包括624名在美国东南部一所公立大学就读的遭受创伤的大学生（68.4%为女性）。数据通过在线调查收集。使用多组结构方程建模方法检验假设模型。
正如假设的那样，PTS通过延迟满足对危险饮酒有显著的正向间接影响；然而，PTS对延迟满足的影响对男性比对女性更强。结果还表明，应对灵活性通过延迟满足对危险饮酒的间接影响对男性和女性均显著且为负向。结论/重要性：本研究结果表明，延迟满足可能是PTS与危险饮酒共同出现的重要潜在机制。此外，我们的结果突出了应对灵活性对遭受PTS的大学生的潜在益处。
