Objective: The current study tested the efficacy of a brief intervention de
signed to reduce drinking and drinking-related consequences among first-yea
r fraternity members. Method: Twelve fraternities were randomly assigned to
receive either a motivational enhancement intervention with individual and
housewide feedback components (n = 6 houses) or a treatment-as-usual contr
ol condition (n = 6 houses). Individual feedback was delivered either by pe
er interviewers or professional research staff. Participants were assessed
during their pledge (first) year of house membership and during a follow-up
period 1 year later. Results: Of the participants who completed follow-up
(N = 120), fraternity members who received the brief intervention reported
significant reductions in alcohol use (total average consumption) and typic
al peak blood alcohol concentrations when compared with fraternity members
in the control condition. No differences in drinking-related consequences w
ere observed. Fraternity members who received their individualized feedback
from peer interviewers and professional members of the research staff repo
rted similar outcomes. Conclusions: Results provide support for the efficac
y of a brief motivational enhancement intervention in reducing drinking wit
hin this high-risk population. The cost-effective use of peer interviewers
appears to be a promising strategy for delivering individualized prevention
programming in college populations.
