Problematic alcohol involvement in college students remains a public health concern and identifying factors that promote this consequential behavior as it occurs in daily life is critical. Recent work has found that whether a drinking event is unplanned vs. planned has implications for the risk of negative consequences, though less work has identified fine-grained predictors of these two types of drinking occasions.
The present study examined drinking motives and positive and negative affect as predictors of unplanned vs. planned drinking in a sample of college students who completed 28 days of ecological momentary assessment (N = 96; 72% White; 52% female). We examined drinking motives reported at two points: (1) in real-time upon initiating drinking and (2) after one day of retrospection (collected at the daily diary report assessing the prior day). Positive and negative affect were both assessed in real-time. Generalized linear mixed-effects models disentangling within- and between-person effects were leveraged.
Drinking "to get high, buzzed, or drunk" - when retrospectively reported for prior-day drinking - exhibited within-person associations with planned drinking, relative to unplanned drinking. This same effect was marginally significant when ascertained in real-time. Individuals with more frequent retrospective endorsement of the motive "to make the day/night more fun" reported more planned drinking. Higher real-time positive affect, but not negative affect, was marginally associated with planned drinking.
Our findings provide preliminary support that enhancement motives and higher positive affect are related to planned drinking, which may inform the development of momentary interventions.
大学生中存在问题的酒精摄入仍然是一个公共卫生关注点，识别日常生活中促进这种后果性行为的因素至关重要。最近的研究发现，饮酒活动是计划的还是非计划的，这对负面后果的风险有影响，但对于这两种饮酒情况的精细预测因素，研究较少。
本研究在一个完成了 28 天生态瞬间评估的大学生样本中，考察了饮酒动机以及积极和消极情绪对非计划与计划饮酒的预测作用（N=96；72%为白人；52%为女性）。我们在两个时间点报告了饮酒动机：（1）在开始饮酒时实时报告，（2）在一天的反思后（在每日日记报告中评估前一天）报告。积极和消极情绪都是实时评估的。利用广义线性混合效应模型来区分个体内和个体间的效应。
当回顾前一天的饮酒情况时，“为了兴奋、陶醉或醉酒”的饮酒动机与计划饮酒有关，而与非计划饮酒无关。当实时确定时，这种效应具有边缘显著意义。更频繁地回顾性认可“使白天/夜晚更有趣”的动机的个体报告了更多的计划饮酒。更高的实时积极情绪，而不是消极情绪，与计划饮酒略有相关。
我们的研究结果初步支持了增强动机和更高的积极情绪与计划饮酒有关，这可能为即时干预的发展提供信息。
