In this study, the authors evaluated the feasibility and efficacy of a binge drinking prevention intervention for college students delivered via the Internet versus a parallel print-based intervention delivered via postal mail. A total of 116 college students completed the baseline survey. The authors then randomized the students into the Web or print group and sent them intervention materials. One hundred and six students completed the posttest survey. The intervention consisted of a series of 4 weekly "newsletters" in electronic or print format. The authors collected data using a standardized online 42-item survey. They found that an Internet-based binge drinking prevention intervention for college students was feasible. Results supported the efficacy of this intervention for those students already binge drinking, regardless of delivery mode. The authors found no significant differences on outcome measures when delivered via the Internet or postal mail. Results lend support to the use of the Internet as a viable alternative to more traditional health intervention delivery methods. (Contains 1 note.)
