Evaluating Personalized Information and Choices

Summary

This research examines a theoretically informed web-based personalized feedback intervention to reduce alcohol-related risky sexual behavior among young adult drinkers. To accomplish this objective the study has enrolled a national sample of 1200 young adults aged 18-20 and is in the process of assessing them at 3-, 6-, 9-, and 12-months. The investigators will evaluate the overall efficacy of the interventions based on the Prototype Willingness Model by comparing underage young adult drinkers randomly assigned to receive the reason-based pathway intervention (n=300), the social-based pathway intervention (n=300), or the integrated intervention based on the full Prototype Willingness Model (both pathways, n=300) to an attention control group (n=300). The investigators will examine whether changes in components of both the reasoned and social pathways and drinking mediate intervention efficacy on reducing alcohol-related risky sexual behavior. Past behavior and college student status will be evaluated as moderators of intervention efficacy. The proposed study is both significant and innovative in that it will evaluate brief interventions among a national sample of young adults attending and not attending college, will utilize social networking sites for participant recruitment, and will test the efficacy of interventions based on individual and integrated pathways of the Prototype Willingness Model.
