导言每日评估研究调查了一天中的特定因素，如情感、社会背景和饮酒动机，以及性格饮酒动机是如何预测年轻人饮酒的。然而，这些研究没有研究饮酒动机(性格和特定日期)和饮酒情况的多种特征之间的相互作用如何预测饮酒的最初决定或饮酒量。通过智能手机技术的生态瞬时评估(EMA)，使我们能够通过评估倾向饮酒动机和特定天的因素在多大程度上与：a)饮酒事件的开始和b)饮酒量相关。方法：参与者是83名年龄在18到30岁(男=21.42，SD=3.09)的年轻人，他们居住在澳大利亚，通过他们的智能手机参与了为期21天的EMA研究。参与者每天都会收到三个随机间隔的提示，分别测量瞬时情感、饮酒动机、社会环境(例如，社会环境中的人以及这些人是否正在饮酒)和酒精使用。结果：多水平障碍分析发现，如果年轻人周围有其他正在饮酒并有饮酒动机的人，他们更有可能发起饮酒事件，并喝下更多的酒精，以符合参照组。结论：这项研究首次证明不同的饮酒行为(即饮酒开始和饮酒量)与一组相似的预测因素有关。针对这些风险因素的以饮酒为基础的干预措施可以有效地减少危险饮酒，因为它将对开始饮酒的决定和继续饮酒的决定进行干预。
Introduction Daily assessment studies have examined how day specific factors, such as affect, social context, and drinking motives, alongside dispositional drinking motives, predict young adult's drinking. However, these studies did not examine how the interplay between drinking motives (dispositional and day specific) and multiple features of the drinking situation predict drinking with respect to either the initial decision to drink or the quantity of alcohol consumed. Ecological momentary assessment (EMA) via smartphone technology, enables us to address this gap by evaluating to what extent dispositional drinking motives and day specific factors are associated with: a) the initiation of drinking episodes and; b) the quantity of alcohol consumed.Methods: Participants were 83 young adults (63 female) aged 18 to 30 (M = 21.42, SD = 3.09) who resided in Australia and participated in an EMA study for 21 days via their smartphone. On a daily basis, participants received three random-interval prompts that measured momentary affect, drinking motives, social context (e.g., people present in the social context and if these individuals are drinking), and alcohol use.Results: A multilevel hurdle analysis found that young adults were more likely to both initiate a drinking episode and consume a higher quantity of alcohol if they were surrounded by other people who were drinking and were motivated to drink to conform to the reference group.Conclusions: This study is the first of its kind to demonstrate that different drinking behaviors (i.e., initiation and quantity of alcohol consumed) are associated with a similar set of predictors. Drinking-based interventions that address these risk factors could effectively reduce risky drinking as it would intervene on both the decision to initiate alcohol use, and the decision to continue drinking.
