In our analysis of the moderated PFI efficacy, we found that experiencing a serious incident prior to the PFI and reporting high levels of AP at baseline were statistically significant moderators of the PFI efficacy favoring the BMI over the WF. These findings indicate that there is an additional benefit of an in-person, face-to-face motivational interview for students who experienced a serious incident or who reported higher levels of AP at baseline. Other individual and situational factors - gender, first-year in college, other drug use, readiness to change, and positive alcohol expectancies – did not moderate the efficacy of the BMI. In addition, the BMI efficacy did not differ across different levels of HED; that is, no interaction effect was found between BMI and baseline HED.
