Notes: PDA = percentage of days abstained from marijuana, last 30 days, as measured by the Timeline Followback Interview; RMPI = Rutgers Marijuana Problem Index; DSMS = total count of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, marijuana abuse + dependence symptoms; a square root transformation was applied to the RMPI data; ns for the analyses ranged from 121 to 149.
