Communication of Alcohol Facts and Hazards by a Warning Poster

Two experiments were conducted to determine whether a warning poster would effectively convey alcohol-related information to college students. In experiment 1, a warning poster containing alcohol facts was posted at several social fraternities. Students’ knowledge of alcohol hazards increased after exposure to the warning, though much of the information was already known. In experiment 2, the poster was refined and included less-well-known facts. Students knowledge increased after exposure to the poster. These results show that posted warnings can effectively communicate important information to one “at-risk” group, college students. Suggestions for improvement and potential utility for other groups at risk are discussed.
