Pi Kappa Phi fraternities pilot tested a shortened version of Prime for Life with its members from 2001 to 2004. Among other findings, members showed a significantly increased perception of risk of drinking a six-pack every Friday or Saturday night. This occurred for all three categories of drinkers, but was greatest among the heaviest drinkers. The 2003-2004 report can be downloaded by clicking below.
