To account for the effect of prevention-message exposure on binge drinking among college students, I hypothesized a conceptual model outlining potential mechanisms including perceived probability of negative consequences (PPNC), perceived severity of negative consequences (PSNC), perceived probability of positive consequences (PPPC), and perceived beneficiality of positive consequences (PBPC) from binge drinking, based on the two-step process model. I conducted an online survey at a public university in the US (N = 278). Findings suggested only PBPC was significantly related to binge drinking and the relationship was positive; prevention-message exposure was not directly associated with binge drinking, but was positively associated with PPNC, PSNC, PPPC, and PBPC; none of the mediational paths was significant; higher risk perception (interaction between PPNC and PSNC) was significantly related to less binge drinking, while benefit perception (interaction between PPPC and PBPC) was not predictive of binge drinking. Implications of findings were discussed.
