A common pattern of problematic alcohol consumption among emerging adults consists of little to no drinking during the week, with heavy drinking episodes on the weekend. However, little is known about whether brief alcohol interventions exert impact on decreasing weekend drinking escalations or simply overall consumption throughout the week. A recent randomized controlled trial of heavy drinking emerging adult nonstudents (N = 164) demonstrated the efficacy of a personalized feedback intervention (PFI). Specifically, the PFI was associated with reduced overall alcohol consumption relative to assessment-only controls. However, it is not clear if patterns of weekend drinking escalation may have been disrupted by the intervention. The current study was a follow-up analysis of the parent trial. Using retrospective daily drinking data provided at each timepoint (up to 9-months), data were coded to reflect condition, time (coded to capture initial changes post-intervention as well as long-term maintenance), and day of the week (coded to capture weekend versus weekday). A multilevel negative binomial hurdle analysis was conducted, yielding two sets of results: 1) predicting the probability of a non-drinking day, and 2) predicting number of drinks consumed. Although the three-way interaction was not significant, 2 two-way interactions indicated that weekend increases in drinking were less steep over time for both groups, and less steep for PFI participants. In addition, the higher weekend likelihood of drinking was decreased over time for both groups. Steep weekend increases in drinking were disrupted over time, particularly among PFI recipients. Personalized feedback may be effective at helping nonstudent emerging adults avoid high risk drinking situations.
在新兴成年人中，一种常见的问题性饮酒模式是在一周内几乎不饮酒，而在周末则大量饮酒。然而，人们对短期的酒精干预是否能减少周末饮酒的增加或仅仅是整个一周的总饮酒量的影响知之甚少。最近一项针对非学生的重度饮酒新兴成年人的随机对照试验（N=164）证明了个性化反馈干预（PFI）的有效性。具体来说，与仅评估对照组相比，PFI 与总体饮酒量减少有关。然而，目前尚不清楚干预是否可能破坏了周末饮酒增加的模式。本研究是对母试验的后续分析。使用在每个时间点（最多 9 个月）提供的回顾性每日饮酒数据，根据条件、时间（编码以捕捉干预后的初始变化以及长期维持）和星期几（编码以捕捉周末与工作日）对数据进行编码。进行了多层次负二项式障碍分析，得出了两组结果：1）预测非饮酒日的概率，2）预测饮酒量。尽管三因素交互作用不显著，但两个双因素交互作用表明，随着时间的推移，两组的周末饮酒量增加都不那么陡峭，PFI 参与者的周末饮酒量增加也不那么陡峭。此外，随着时间的推移，两组的周末饮酒可能性都降低了。周末饮酒量的急剧增加随着时间的推移而中断，尤其是在 PFI 接受者中。个性化反馈可能有助于非学生新兴成年人避免高风险的饮酒情况。
