Moreno MA, D'Angelo J, Hendriks H, et al. - This 5-year study sought to present alcohol and abstinence display patterns on Facebook. Researchers conducted a prospective longitudinal cohort study including incoming 17- to 19-year-old college students from two universities upon entering college. Trained coders investigated Facebook profiles monthly over five years to distinguish alcohol and abstinence displays. A total of 338 individuals were included (mean age = 18.4, SD = .6), 56.1% were female, 74.8% were Caucasian, and 58.8% were from Midwest college. This 5-year study demonstrates patterns of alcohol and abstinence displays throughout the undergraduate experience. The study illustrates that observations may inform planning targeted interventions by time point, or longitudinal studies of other substances or on different platforms.
