Affect regulation models of drinking state that affect motivates and reinforces drinking. Few studies have been able to elucidate the timing of these associations in natural settings. We tested positive affect (PA) and negative affect (NA) as predictors of drinking behavior, both prior to and during drinking episodes, and whether drinking predicted changes in affect during episodes.
Two hundred twenty-two regularly drinking young adults (21-29 years, 84% undergraduates), completed an ecological momentary assessment (EMA) protocol for five consecutive 24-hr periods stretching across 6 days (Wednesday-Monday). Participants provided PA and NA reports three times daily and every half hour during drinking episodes. Alcohol consumption reports were provided each morning and every half hour during drinking episodes.
Multi-level models showed that greater pre-drinking PA predicted higher odds of drinking, but not number of drinks consumed. Pre-drinking NA did not predict same day odds of drinking or drinks consumed. Episode-level results revealed different associations for PA and NA with drinking. Current PA did not predict drinks consumed over the next half hour; however, increased drinking was associated with greater increases in PA over the next half hour. Higher NA predicted fewer drinks consumed in the next half hour and higher odds of the end of a drinking episode; however, increased drinking was not associated with changes in NA.
PA increased following drinking during episodes. Our results suggest that a focus on PA prior to episodes and a focus on NA during episodes may interrupt processes leading to heavy drinking, and may therefore aid prevention efforts. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
饮酒状态的情绪调节模型表明情绪会激发并强化饮酒行为。很少有研究能够阐明这些关联在自然环境中的发生时间。我们测试了积极情绪（PA）和消极情绪（NA）作为饮酒行为的预测因素，包括在饮酒发作之前和期间，以及饮酒是否预测发作期间情绪的变化。
222名经常饮酒的年轻人（21 - 29岁，84%为本科生），在连续6天（周三至周一）的五个连续24小时内完成了一项生态瞬时评估（EMA）方案。参与者每天提供三次PA和NA报告，在饮酒发作期间每半小时提供一次。每天早晨以及饮酒发作期间每半小时提供饮酒量报告。
多层次模型显示，饮酒前较高的PA预测饮酒几率更高，但不预测饮酒量。饮酒前的NA不能预测当天的饮酒几率或饮酒量。发作水平的结果揭示了PA和NA与饮酒的不同关联。当前的PA不能预测接下来半小时内的饮酒量；然而，饮酒量增加与接下来半小时内PA的更大增加相关。较高的NA预测接下来半小时内饮酒量较少以及饮酒发作结束的几率较高；然而，饮酒量增加与NA的变化无关。
发作期间饮酒后PA会增加。我们的结果表明，关注发作前的PA以及发作期间的NA可能会中断导致大量饮酒的过程，因此可能有助于预防工作。（PsycInfo数据库记录（c）2021美国心理学会，保留所有权利）
