BACKGROUND: Black college students experience elevated minority stress, particularly racial discrimination, which has been linked to greater alcohol use and related harms. Yet, research on this disparity overwhelmingly relies on cross-sectional or retrospective designs that fail to capture the dynamic nature of racial discrimination and its real-time influence on alcohol use risk. This study used ecological momentary assessment (EMA) to examine daily associations between racial discrimination and alcohol use in this population.
METHODS: Black undergraduate and graduate students (N = 97;76% women) attending four predominantly White institutions completed 14 days of EMAs (five random daily prompts plus a morning survey capturing overnight experiences). Daily racial discrimination (any vs. none) and alcohol use (any use, quantity) were aggregated and modeled with multilevel generalized linear models testing between-person, within-person concurrent, and lagged effects, controlling for demographic covariates.
RESULTS: Participants reported an average of 6.77 racial discrimination incidents across 14 days. After accounting for between-person differences in discrimination frequency, within-person analyses showed that on days when students experienced racial discrimination, they consumed more alcohol that same day (p = .020). Experiencing racial discrimination on one day was also associated with greater alcohol consumption the following day (p < .001) and 1.69 × higher odds of next-day drinking initiation (p = .015). Notably, higher average racial discrimination (between-person) was not associated with alcohol use once lagged effects were considered.
CONCLUSIONS: Findings underscore the need for culturally responsive, real-time interventions addressing the episodic and temporally persistent nature of discrimination-related alcohol risk among Black college students, including both drinking initiation and escalation.
