People often report drinking to cope with negative affect (NA) or to enhance positive affect (PA). However, findings from daily life studies examining the interaction of motives and affect to predict alcohol use are mixed. Individuals with borderline personality disorder (BPD) may be particularly susceptible to drinking for the purpose of changing affective states, representing a population in which these patterns may be more readily identifiable in daily life. We tested whether drinking motives moderate daily life associations between affect and drinking in individuals with BPD. Regular drinkers with BPD (N = 54; 81.5% female) completed ecological momentary assessments approximately 6-10 times daily for 21 days. We tested whether the interactions between (a) person-level coping motives and NA so far that day (i.e., cumulative-average NA), and (b) person-level enhancement and cumulative-average PA were associated with subsequent drinking. We also tested whether effects differed for the initiation versus continuation of a drinking episode. Using generalized estimating equations, the interaction between coping and cumulative-average NA was positively associated with momentary drinking, with some evidence for a stronger relation during the continuation of drinking. The interaction between enhancement motives and cumulative-average PA was positively associated with initiation but negatively associated with continuation of drinking. Our novel approach of using cumulative-average affect and distinguishing initiation and continuation of drinking allowed us to examine differential momentary patterns across the drinking episode, and results suggest that awareness of motives as well as affect leading up to and during drinking may be a useful intervention target.

饮酒动机调节边缘型人格障碍患者的情感与饮酒之间的日常生活关联。


人们经常报告说喝酒是为了应对负面情绪（NA）或增强正面情绪（PA）。然而，日常生活研究中检查动机和影响之间的相互作用以预测饮酒情况的结果好坏参半。患有边缘性人格障碍（BPD）的人可能特别容易为了改变情感状态而饮酒，这代表了在日常生活中更容易识别这些模式的人群。我们测试了饮酒动机是否会调节 BPD 患者日常生活中情感与饮酒之间的关联。患有 BPD 的经常饮酒者（N = 54；81.5% 女性）每天完成大约 6-10 次生态瞬时评估，持续 21 天。我们测试了（a）个人层面的应对动机和当天迄今为止的NA（即累积平均NA）和（b）个人层面的增强和累积平均PA之间的相互作用是否与随后的饮酒有关。我们还测试了饮酒开始与持续的影响是否不同。使用广义估计方程，应对和累积平均NA之间的相互作用与短暂饮酒呈正相关，一些证据表明在持续饮酒期间这种关系更强。增强动机和累积平均 PA 之间的相互作用与开始饮酒呈正相关，但与继续饮酒呈负相关。我们使用累积平均情感并区分饮酒的开始和持续的新方法使我们能够检查整个饮酒过程中不同的瞬时模式，结果表明，对动机以及饮酒前和饮酒期间的情感的认识可能是一种有用的干预措施目标。 （PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
