Abstract

Objective: Perception of others' approval of alcohol use (i.e., injunctive drinking norms) is strongly predictive of alcohol use, particularly among young adults. Although between-person injunctive norms predict alcohol use, there is evidence of within-person fluctuations in the relationship between norms and drinking. The current study used ecological momentary assessment (EMA) to test within-person, day-level associations between injunctive norms and alcohol use and to test whether social context moderated this association.

Method: Participants (n = 83, M age = 24.0 years, 50.9% female) completed a 2-week EMA protocol using a smartphone application. Injunctive norms, social context (type and gender of companions), and number of drinks consumed were assessed each morning following a drinking event. Multilevel models with repeated measures nested within participants tested main effects and interactions of between- and within-person injunctive norms, type of drinking companions, and gender of drinking companions on the number of drinks consumed.

Results: Day-level injunctive norms were positively associated with drinking quantity over and above baseline norms. The effect of norms differed by social context, such that norms were only positively related to drinking quantity when drinking with a friend or romantic partner (vs. drinking alone). The gender of friends with whom participants drank did not moderate the effect of norms on quantity.

Conclusions: This study provides one of the first examinations of daily fluctuations in injunctive drinking norms. Because norms represent a malleable target for intervention, results offer new information regarding possible intervention targets.

强制饮酒规范与酒精消费之间的日常关联。
目的:感知他人对饮酒的认可(即强制性饮酒规范)对饮酒有很强的预测作用,尤其是在年轻人中(Krieger 等人,2016 年)。虽然人与人之间的强制规范可以预测饮酒(Neighbors 等人,2008 年),但也有证据表明人与人之间的规范与饮酒之间的关系存在波动(Graupensperger 等人,2021 年)。本研究使用生态瞬间评估(EMA)来测试人内、日水平的强制规范与饮酒之间的关系,并测试社会环境是否调节了这种关系:参与者(83 人,平均年龄 24.0 岁,50.9% 为女性)使用智能手机应用程序完成了为期两周的 EMA 方案。在饮酒事件发生后的每天早晨,对戒酒规范、社会环境(同伴的类型和性别)以及饮酒数量进行评估。在参与者中嵌套重复测量的多层次模型检验了人与人之间和人与人之间的强制规范、饮酒同伴的类型和饮酒同伴的性别对饮酒数量的主效应和交互作用:结果:在基线标准之上,日强制标准与饮酒量呈正相关。不同的社会环境对规范的影响也不同,只有在与朋友或恋人一起饮酒(与独自饮酒相比)时,规范才与饮酒量呈正相关。与参与者一起喝酒的朋友的性别并不影响规范对饮酒量的影响:本研究首次对强制饮酒规范的日常波动进行了研究。由于饮酒规范是一个可塑的干预目标(White 等人,2019 年),研究结果为可能的干预目标提供了新的信息。

期刊介绍: The Journal of Studies on Alcohol and Drugs began in 1940 as the Quarterly Journal of Studies on Alcohol. It was founded by Howard W. Haggard, M.D., director of Yale University’s Laboratory of Applied Physiology. Dr. Haggard was a physiologist studying the effects of alcohol on the body, and he started the Journal as a way to publish the increasing amount of research on alcohol use, abuse, and treatment that emerged from Yale and other institutions in the years following the repeal of Prohibition in 1933. In addition to original research, the Journal also published abstracts summarizing other published documents dealing with alcohol. At Yale, Dr. Haggard built a large team of alcohol researchers within the Laboratory of Applied Physiology—including E.M. Jellinek, who became managing editor of the Journal in 1941. In 1943, to bring together the various alcohol research projects conducted by the Laboratory, Dr. Haggard formed the Section of Studies on Alcohol, which also became home to the Journal and its editorial staff. In 1950, the Section was renamed the Center of Alcohol Studies.
