OBJECTIVE
Types of college drinkers have been identified using traditional measures (e.g., 12-month drinking frequency). We used an alternative multidimensional approach based on daily reports of alcohol behaviors to identify college drinker statuses, each with a unique behavioral profile. The current study aimed to (a) identify drinker statuses at the week level across four semesters, (b) examine the predictive utility of drinker status by testing associations with senior-year hazardous drinking and dependence symptoms, and (c) identify concurrent predictors (gender, drinking motivations, hazardous drinking, any dependence symptoms) of senior-year drinker status. We also compared the week-level drinker statuses with drinker statuses identified using traditional measures.
METHOD
A multi-ethnic sample of U.S. college students completed 14-day bursts of daily web surveys across college (91%-96% completed ≥6 daily reports of the sampled week). Analyses focus on nine alcohol-related behaviors (including estimated blood alcohol concentration, pregaming, and drinking games) assessed daily in spring/sophomore year to fall/senior year and drinking motivations, hazardous drinking, and dependence symptoms assessed fall/senior year (n = 569; 56% women).
RESULTS
Four week-level drinker statuses were replicated across semesters: Nondrinker, Light Weekend, Heavy Weekend, and Heavy Frequent. Across semesters, drinker status was associated with senior-year hazardous drinking and any dependence symptoms. Senior-year fun/social motivations were also associated with senior-year drinker status. Differences in behavioral profiles between week-level drinker statuses and those identified using traditional measures were found.
CONCLUSIONS
Replicable week-level drinker statuses were identified, suggesting consistency in possible types of drinking weeks. Drinker statuses were predictive of senior-year hazardous drinking and dependence symptoms.
目的
已使用传统测量方法（如12个月饮酒频率）确定了大学生饮酒者的类型。我们采用了一种基于酒精行为每日报告的替代多维方法来确定大学生饮酒者状态，每种状态都有独特的行为特征。本研究旨在：（a）确定四个学期中每周的饮酒者状态；（b）通过测试与高年级危险饮酒和依赖症状的关联来检验饮酒者状态的预测效用；（c）确定高年级饮酒者状态的并发预测因素（性别、饮酒动机、危险饮酒、任何依赖症状）。我们还将每周的饮酒者状态与使用传统测量方法确定的饮酒者状态进行了比较。
方法
一个多民族的美国大学生样本在大学期间完成了为期14天的每日网络调查（91%-96%的人完成了抽样周中≥6天的每日报告）。分析重点关注从春季/大二学年到秋季/大四学年每天评估的九种与酒精相关的行为（包括估计血液酒精浓度、预饮和饮酒游戏），以及在秋季/大四学年评估的饮酒动机、危险饮酒和依赖症状（n = 569；56%为女性）。
结果
四个每周饮酒者状态在各学期中得到了重复：不饮酒者、轻度周末饮酒者、重度周末饮酒者和重度频繁饮酒者。在各学期中，饮酒者状态与高年级危险饮酒和任何依赖症状相关。高年级的娱乐/社交动机也与高年级饮酒者状态相关。发现了每周饮酒者状态与使用传统测量方法确定的状态之间行为特征的差异。
结论
确定了可重复的每周饮酒者状态，表明可能的饮酒周类型具有一致性。饮酒者状态可预测高年级危险饮酒和依赖症状。
