Abstract: The present study experimentally investigated the interplay between interpersonal communication and health message exposure in relation to alcohol consumption intentions. One hundred and seventy-four students participated in a study on the effects of an anti-alcohol message. At baseline, intention to refrain from binge drinking was assessed, whilst at the second wave (two weeks later) participants were assigned to the conditions of a 2 (anti-alcohol message or no alcohol message) x 2 (alcohol conversation or control conversation) between-subjects design, after which intention was again assessed. Results showed that when participants talked about alcohol (instead of the control topic) and were not exposed to an anti-alcohol message they were less inclined to refrain from binge drinking, an effect that was not visible when participants talked about alcohol after viewing an anti-alcohol message. These findings suggest that health campaign exposure moderates the influence of interpersonal communication on health variables.
