In praise of feedback: an effective intervention for college students who are heavy drinkers.

The efficacy of brief motivational feedback to reduce drinking among college students has been reported by several researchers. As an extension of this theoretical and applied framework, the author tested the use of mailed feedback to influence the drinking behavior of students self-identified as moderate-to-heavy drinkers in two randomized trials. A 6-week follow-up of the efforts suggested the efficacy of the feedback intervention at reducing alcohol consumption. The feedback mechanism used in the studies is described in detail and possible reasons for its efficacy are explored. In light of the cost-effective nature of this intervention, it may warrant a place in larger campus prevention programs.
