Students living in off-campus housing consume more alcohol and experience more alcohol-related consequences than those living on campus, yet prevention efforts have not targeted this high-risk group specifically. The present study evaluated the efficacy of a brief, computer-delivered, alcohol intervention (the College Drinkers Check-Up [CDCU]) in reducing alcohol use and related consequences in a sample of college students living off campus.
Students who lived off campus and reported at least one heavy drinking episode (4+/5+ drinks for females/males in one occasion) in the past 30 days completed the CDCU or assessment only during the first month of the school year (n = 326; 61% female). Participants in both conditions completed follow-up assessments at 1, 3, and 6 months. We hypothesized that participants who completed the CDCU would report fewer drinks per week and heavy drinking episodes, lower peak drinking quantities, and fewer alcohol-related consequences than those in the control group.
Hierarchical linear modeling was used to examine changes in drinking outcomes across groups from baseline to 1-, 3-, and 6-month follow-ups. Significant effects of time indicated less drinking and fewer consequences at each follow-up relative to baseline. Compared with those in the control group, participants who received the CDCU reported significantly fewer heavy drinking episodes at 1 month, lower peak drinking quantities at 3 months, and fewer alcohol-related consequences at 1 and 3 months. Neither sex nor baseline drinking severity moderated intervention effects.
The brief, online CDCU reduces heavy drinking and alcohol consequences in the short term among atrisk college students living off campus.
与住在校内的学生相比，住在校外的学生饮酒量更大，且经历更多与酒精相关的不良后果，但预防措施尚未专门针对这一高风险群体。本研究评估了一种简短的、通过计算机提供的酒精干预措施（大学生饮酒检查[CDCU]）在减少校外居住大学生样本中的酒精使用及相关不良后果方面的效果。
在学年的第一个月，那些住在校外且报告在过去30天内至少有一次酗酒事件（女性/男性一次饮用4杯以上/5杯以上）的学生完成了CDCU或仅进行了评估（n = 326；61%为女性）。两种情况下的参与者均在1、3和6个月时完成了随访评估。我们假设，完成CDCU的参与者每周饮酒量和酗酒事件会比对照组更少，饮酒峰值量更低，与酒精相关的不良后果也更少。
采用分层线性模型来检验从基线到1个月、3个月和6个月随访期间各组饮酒结果的变化。时间的显著影响表明，每次随访时相对于基线饮酒量减少，不良后果也减少。与对照组相比，接受CDCU的参与者在1个月时报告的酗酒事件显著减少，在3个月时饮酒峰值量更低，在1个月和3个月时与酒精相关的不良后果更少。性别和基线饮酒严重程度均未调节干预效果。
简短的在线CDCU在短期内可减少校外居住的高危大学生的酗酒行为及酒精相关不良后果。
