Objective: The purpose of this study was to determine which type of prevention message (abstinence, social norms, or responsible drinking) was most effective at reducing alcohol consumption. Participants: The subjects from this study included 194 college students from a public university. Methods: Researchers employed a quasi-experimental design, collecting pre/post-test data to evaluate the messages. Results: Post-hoc procedures revealed the following significant effects from the MANOVA: (a) abstinence message F(1,191) = 4.36, p = 0.038, (b) social norms message, F(1,191) = 4.27, p = 0.040; and (c) drink responsibly message F(1,191) = 4.09, p = 0.045. Conclusions: Each of the messages resulted in decreased alcohol consumption among at least one of the indicators, although the abstinence message was the most effective overall.
