Objective: Sexual minority women (SMW) evidence elevated rates of trauma exposure, posttraumatic stress (PTS), and alcohol consumption. Self-medication models of drinking suggest that individuals may drink to cope with symptoms of PTS, but this possibility remains untested among SMW. Method: The current study used data from drinking days collected via daily diary assessments from 81 trauma-exposed SMW. Participants were mostly White (72.8%) and ranged in age from 18 to 25 (M = 23.8). Participants were followed over 2 14-consecutive-day measurement bursts (720 person-days reported). Analyses were conducted to examine whether coping drinking motives (vs. social, enhancement, and conformity drinking motives), as assessed by an adapted Drinking Motives Questionnaire, mediated the daily level relationship between PTS symptoms (assessed by the PTSD Checklist) and the number of standard drinks per drinking day. Results: Results from multilevel structural equation models indicated that day-to-day fluctuations in PTS symptoms, as well as average levels of PTS symptoms, were associated with increased coping drinking motives. Coping drinking motives, but not other drinking motives, mediated within-person associations between PTS and drinking, such that daily fluctuations in PTS symptoms were associated with stronger-than-normal coping drinking motives, which in turn predicted more drinks per drinking day. Conclusions: Results highlight the importance of coping drinking motives and suggest that alternative coping strategies may help trauma-exposed SMW to manage heightened PTS symptoms without increasing their alcohol consumption.

遭受创伤的性少数女性的创伤后应激症状、饮酒动机和饮酒之间的日常关系。

目的：性少数女性 (SMW) 的证据表明，创伤暴露、创伤后压力 (PTS) 和饮酒率升高。饮酒的自我药疗模型表明，个人可能会饮酒以应对 PTS 的症状，但这种可能性在 SMW 中仍未得到检验。方法：目前的研究使用了从 81 名受过创伤的 SMW 中通过日常日记评估收集的饮酒天数数据。参与者大多是白人（72.8%），年龄从 18 岁到 25 岁不等（M = 23.8）。参与者被跟踪超过 2 个连续 14 天的测量突发（报告为 720 人天）。进行分析以检查是否应对饮酒动机（与社交、增强和顺从性饮酒动机相比），如通过改编的饮酒动机问卷评估的那样，介导了 PTS 症状（由 PTSD 检查表评估）与每天饮用标准饮料数量之间的每日水平关系。结果：多层次结构方程模型的结果表明，PTS 症状的日常波动以及 PTS 症状的平均水平与应对饮酒动机的增加有关。应对饮酒动机，而不是其他饮酒动机，介导了 PTS 和饮酒之间的人内关联，因此 PTS 症状的每日波动与比正常情况更强烈的应对饮酒动机有关，这反过来又预示着每天饮酒会更多。结论：结果强调了应对饮酒动机的重要性，并表明替代应对策略可能有助于遭受创伤的 SMW 在不增加饮酒量的情况下控制加重的 PTS 症状。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
