Note. CSA = Campus Structured Activities. “Concurrent” refers to analyses that assessed the association between leisure activities and substance use in the same year (wave 8); “Longitudinal” refers to analyses examining the association of leisure activities in wave 8 with substance use in wave 9. Participants chose one of the following responses for past month substance use: 0=0 days, 1=1 day, 2=2 days, 3=3–5 days, 4=6–9 days, 5=10–19 days, and 6=20–30 days. These response options were rescaled to the mid-point of number of days (e.g., 3–5 days = 4).
