The global outbreak of coronavirus disease 2019 (COVID-19) and the resulting lockdown measures have raised concerns regarding their effect on alcohol consumption. We investigated alcohol use during lockdown in a population of college students, usually characterized by social and heavy drinking. We also tested the predictive role of pre-lockdown drinking motives on alcohol consumption during lockdown. We collected data from 1951 French-speaking Belgian students during the lockdown period (April 1st – May 3rd, 2020) through a cross-sectional online survey. Participants self-reported their daily alcohol consumption (1) during a typical week in normal circumstances (i.e., before lockdown), and (2) since lockdown onset. We also assessed drinking motives and severity of alcohol use before lockdown. Our findings showed that 68.2% of the sample reported a lower alcohol consumption during lockdown compared to before lockdown, 17.2% conversely reporting a higher consumption. Enhancement, social and coping motives were all associated with heavy drinking before lockdown. Enhancement and social motives predicted lower alcohol consumption during lockdown among heavy drinkers. Conversely, coping motives, as well as social motives among low drinkers, predicted higher consumption during lockdown. Conformity motives, as well as enhancement motives among low and moderate drinkers, did not predict alcohol consumption before or during lockdown. Overall, several pre-lockdown drinking motives reliably predicted alcohol consumption during lockdown and could thus be used to identify at-risk populations and to tailor intervention programs on alcohol misuse during sanitary crises.

全球冠状病毒病2019（COVID-19）的爆发以及随之而来的封锁措施引起了人们对其对饮酒影响的担忧。我们调查了一些大学生在锁定期间的饮酒习惯，通常以社交和大量饮酒为特征。我们还测试了锁定前饮酒动机对锁定期间饮酒的预测作用。我们通过跨部门在线调查收集了在锁定期间（2020年4月1日至2020年5月3日）来自1951年讲法语的比利时学生的数据。参与者自我报告自己的每日饮酒量（1）在正常情况下（即，在锁定之前）的一个典型星期内，以及（2）自锁定开始以来的每日饮酒量。在锁定之前，我们还评估了饮酒动机和酒精使用的严重程度。我们的调查结果显示68。与锁定之前相比，有2％的样本报告了锁定期间的酒精消耗较低，相反，有17.2％的样本报告了较高的酒精消耗。增强，社交和应对动机都与禁酒前大量饮酒有关。增强和社会动机预测，在酗酒者锁定期间，酒精消耗会降低。相反，低饮酒者的应对动机以及社会动机预示着锁定期间的消费量会增加。适中动机以及中低度饮酒者的增强动机并未预测锁定之前或锁定期间的酒精消耗。总体而言，锁定前的几种饮酒动机可以可靠地预测锁定期间的饮酒量，因此可用于识别高危人群并制定卫生危机期间滥用酒精的干预计划。
