OBJECTIVE: A debate remains regarding whether parents should teach their children harm-reduction tips for using alcohol while in college or whether they should maintain a zero-tolerance policy. Which type of alcohol-related communication parents should endorse is not empirically clear. The current study made use of a longitudinal measurement-burst design to examine this issue. METHOD: The sample consisted of 585 second-year students from a large university in the northeastern United States. Participants completed a baseline survey and 14 daily web-based surveys. Students were assessed for perceptions of parental alcohol-related messages and their own alcohol use. Multilevel models were estimated using HLM 6.04. RESULTS: The data indicate that zero-tolerance messages appeared most protective against alcohol use and consequences. Harm-reduction messages were most risky, even when compared with mixed messages or the absence of a message. CONCLUSIONS: Findings indicate that a zero-tolerance approach was associated with safer outcomes than other messages, even if students were already using alcohol.
