Subjective response to alcohol is a robust predictor of alcohol outcomes. It is possible that the perceived subjective response of others may influence concurrent experiences of one's own subjective response. However, no studies have examined how the perceived subjective response of others might interact with personal subjective response and how such interactions may influence levels of craving and subsequent drinking.
Emerging adults (ages 18-25, N = 131, 53.4 % female) completed 21 days of ecological momentary assessments. During drinking events (N = 1335) both personal and perceived peer subjective response (four domains encompassing high- and low-arousal positive & negative effects) were assessed at drink initiation and two subsequent surveys 60 and 120min later. Current craving and drinking quantity since last report were also collected. Three-level multilevel structural equation models with Bayesian estimation tested indirect relations between subjective response and drinking continuation via craving and whether perceived subjective response moderated such relations.
Levels of both personal (b=0.029,95 %BCI:[0.012,0.053]) and perceived (b=0.027,95 %BCI:[0.012,0.051]) experiences of alcohol's rewarding, stimulating effects indirectly predicted drinking continuation via increased craving, and relations were potentiated when perceptions of peer reward were highest (b=0.015,95 %BCI:[0.008,0.020]). Personal experiences of alcohol's relaxing, calming effects indirectly predicted a lower likelihood of drinking continuation via decreased craving (b=-0.017,95 %BCI:[-0.036,-0.003]) whereas perceived effects directly predicted lower likelihoods of drinking (b=-0.133,95 %CI:[-0.239, -0.031]).
Results suggest both personal and perceived peer subjective response independently influence drinking behavior even when controlling for one another. Targeted interventions focused on altering interpretations of peer subjective effects may be effective at reducing momentary risk.
对酒精的主观反应是酒精相关结果的有力预测指标。他人的感知主观反应可能会影响自身主观反应的同时体验。然而，尚无研究探讨他人的感知主观反应如何与个人主观反应相互作用，以及这种相互作用如何影响渴望程度和后续饮酒行为。
新兴成年人（年龄18 - 25岁，N = 131，53.4%为女性）完成了21天的生态瞬时评估。在饮酒事件中（N = 1335），在饮酒开始时以及随后60分钟和120分钟的两次调查中，评估个人和感知到的同伴主观反应（包括高唤醒和低唤醒的积极与消极影响的四个领域）。还收集了自上次报告以来的当前渴望程度和饮酒量。采用贝叶斯估计的三级多水平结构方程模型检验主观反应与通过渴望程度的饮酒持续之间的间接关系，以及感知主观反应是否调节这种关系。
酒精的奖励、刺激作用的个人体验（b = 0.029，95%BCI：[0.012，0.053]）和感知体验（b = 0.027，95%BCI：[0.012，0.051]）均通过增加渴望程度间接预测饮酒持续，当同伴奖励感知最高时，这种关系会增强（b = 0.015，95%BCI：[0.008，0.020]）。酒精的放松、平静作用的个人体验通过降低渴望程度间接预测饮酒持续的可能性较低（b = -0.017，95%BCI：[-0.036，-0.003]），而感知到的作用直接预测饮酒可能性较低（b = -0.133，95%CI：[-0.239，-0.031]）。
结果表明，即使相互控制，个人和感知到的同伴主观反应也会独立影响饮酒行为。针对改变对同伴主观影响的解读的有针对性干预措施可能有效降低瞬时风险。
