Background: The COVID-19 pandemic and lockdowns are known to affect alcohol consumption. This study examines drinking expectancies and contexts upon alcohol consumption of Argentinean students. Objectives: To assess within-person changes in alcohol consumption in Argentinean college students (aged 18–24), from August 2019 with a one-year follow-up during the COVID-19 lockdown, considering alcohol expectancies, drinking contexts, and main socio-demographic variables. To validate the stability of these predictors, we discuss the effects on the alcohol consumption across dependent and independent measures. Methods: We assessed one longitudinal (N = 300, 70% female) and one cross-sectional (N = 165, 78% female) sample via online surveys and applied multilevel analysis and regressions, respectively. Results: Alcohol consumption significantly increased during lockdown compared to one-year before (mean: 6.91 and 8.26 alcohol units, correspondingly). In the longitudinal sample, social facilitation (medium effect sizes [ES]: 0.21, 0.22) and parental presence (medium ES: 0.12, 0.21) significantly and stable (through time) predicted increasing effects on consumption. In the cross-sectional sample, stress control (high ES: 0.78) and parental presence (high ES: 0.42) were associated with higher consumption during lockdown. Conclusion: College students increased their alcohol consumption during lockdown, suggesting that restrictive sanitary measures may negatively affect consumption. Literature is not conclusive as both decreases and increases in alcohol consumption in students from developed countries were reported. Before and during COVID-19 lockdown, parental presence is a stable predictor of increased alcohol consumption, though unusual according to the literature. Health policies aimed at modifying the behavior of parents who promote/share alcohol consumption with their offspring may help reduce drinking in college students.
