First-year students in college are generally considered to be at risk for excessive alcohol use. Although evidence of the efficacy of PFIs exists for first-year college students (see Larimer & Cronce, 2007), PFIs may be less beneficial for first-year students according to Carey, Scott-Sheldon et al. (2007). However, it is unclear whether the efficacy of PFIs works differently for first-year students, compared to non first-year students, when their different patterns of alcohol use are controlled. In addition, many mandated students get caught for drug use. The current study also investigates whether other drug use at baseline moderates PFI efficacy among mandated students.
