Trauma exposure and drinking motives (e.g., social, enhancement, coping) are both associated with increased alcohol use and related problems. Studies have frequently investigated this relationship by examining drinking motives, such as drinking to cope with negative affect, in isolation, yet few studies have examined motives simultaneously in trauma-exposed populations. It is also unclear whether the relationship between drinking motives and alcohol use outcomes differs as a function of population characteristics (e.g., gender, trauma type). Using latent profile analysis (LPA), we aimed to 1) identify latent profiles characterized by drinking motives, assessed with the Drinking Motives Questionnaire (DMQ), in two samples: primarily male veterans with combat trauma (=174) and civilians with interpersonal trauma (=152), and 2) determine whether associations with alcohol use outcomes of consumption and binge drinking would differ by sample. A 3-class solution was replicated across both samples: profiles characterized by moderate Social scores and low Enhancement and Coping scores (Low ENH/COP), moderate scores across all domains (Medium DMQ), and elevated scores across all domains (High DMQ). In both samples, profile membership was differentially associated with consumption and binge drinking. Findings suggest patterns of drinking motives may be similar across different trauma-exposed populations, but associations with alcohol outcomes likely differ in meaningful ways. Results can help inform targeted interventions at different treatment settings, such as community health centers or VA hospitals.
创伤暴露和饮酒动机（如社交、强化、应对）都与酒精使用增加及相关问题有关。研究经常通过单独考察饮酒动机（如为应对负面影响而饮酒）来研究这种关系，但很少有研究在经历创伤的人群中同时考察多种动机。饮酒动机与酒精使用结果之间的关系是否因人群特征（如性别、创伤类型）而异也尚不清楚。我们使用潜在剖面分析（LPA）旨在：1）在两个样本中识别以饮酒动机为特征的潜在剖面，这些动机通过饮酒动机问卷（DMQ）进行评估，这两个样本分别是主要为经历战斗创伤的男性退伍军人（=174）和经历人际创伤的平民（=152）；2）确定与饮酒消费和暴饮的酒精使用结果的关联在不同样本中是否存在差异。在两个样本中都重复得到了一个三类解决方案：以中等社交得分以及低强化和应对得分（低ENH/COP）为特征的剖面、所有领域得分中等（中等DMQ）的剖面以及所有领域得分较高（高DMQ）的剖面。在两个样本中，剖面归属与饮酒消费和暴饮存在不同程度的关联。研究结果表明，不同经历创伤的人群中饮酒动机模式可能相似，但与酒精使用结果的关联可能在有意义的方面存在差异。这些结果有助于为不同治疗环境（如社区健康中心或退伍军人事务部医院）的针对性干预提供信息。
