Randomized Controlled Trial of a Web-Delivered Personalized Normative Feedback Intervention to Reduce Alcohol-Related Risky Sexual Behavior Among College Students

摘要

Objective: The purpose of this study was to evaluate the efficacy of'personalized normative feedback (PNF) on college student alcohol-related risky sexual behavior (RSB). Method: In a randomized controlled trial, 480 (57.6% female) sexually active college students were stratified by gender and level of drinking and randomly assigned to an alcohol-only intervention, an alcohol-related RSB-only intervention, a combined alcohol and alcohol-related RSB intervention, or control. All assessment and intervention procedures were Web-based. Results: Results indicated a significant reduction in drinking outcomes for the alcohol only and the combined alcohol and alcohol-related RSB interventions relative to control. Findings further demonstrated a significant reduction in alcohol-related RSB outcomes for the alcohol-related RSB only and the combined alcohol and alcohol-related RSB interventions relative to control. There were no significant intervention effects on alcohol-related negative consequences. These findings demonstrate that the combined alcohol and alcohol-related RSB intervention was the only intervention successful at reducing both drinking and alcohol-related RSB outcomes relative to control. There were no significant differences when comparing the combined alcohol and alcohol-related RSB intervention to the alcohol-only intervention or the alcohol-related RSB-only intervention. Finally, results suggested that the intervention effects on high-risk behaviors were mediated by reductions in descriptive normative perceptions. Conclusions: These findings demonstrate that PNF specific to drinking in sexual situations was needed to reduce alcohol-related RSB. Furthermore, this study highlights the potential utility of a brief intervention that can be delivered via the Internet to reduce high-risk drinking and alcohol-related RSB among college students.
