Informing Alcohol-Related Risk Intervention with the Prototype Willingness Model

描述（由申请人提供）：本研究将研究基于网络的个性化反馈干预，以减少18-20岁未成年青年饮酒者与酒精相关的性风险行为，该干预在理论上由原型意愿模型提供信息。基于关注青少年和年轻人发育适宜健康模型的文献，原型意愿模型假设了风险行为的两条途径：一条是理性的途径，另一条是基于社会的途径。先前的研究表明，与原型意愿模型相一致的干预措施，或基于原型意愿模型组成部分的干预措施，在减少酒精使用和危险性行为方面是有效的。尽管这一模式具有实用性，但它尚未得到应用

DESCRIPTION (provided by applicant): The proposed research will examine a web-based personalized feedback intervention to reduce alcohol-related risky sexual behavior among underage young adult drinkers aged 18-20, which is theoretically informed by the Prototype Willingness Model. Based on literature focusing on developmentally appropriate health models for adolescents and young adults, the Prototype Willingness Model assumes two pathways to risk behavior: one pathway that is reasoned and one pathway that is socially based. Prior research has shown that interventions consistent with the Prototype Willingness Model, or interventions based on components of the Prototype Willingness Model, are efficacious at reducing alcohol use and risky sexual behavior. Despite the utility of this model, it has yet to be applied to examining whether interventions comprised of components from both pathways of the PW Model are efficacious at reducing alcohol-related risky sexual behavior in underage young adult drinkers. Moreover, no research has examined the active components (reasoned pathway vs. social pathway) of this model. The research proposed in this application is designed to evaluate a personalized feedback intervention, based on the Prototype Willingness Model, focused on alcohol-related risky sexual behavior through a longitudinal study in a national sample of young adults (college and non-college) recruited via social networking sites. To accomplish this objective the study will enroll a national sample of 1,200 young adults aged 18-20 and assess them at 3-, 6, 9-, and 12-months. We 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 reasoned-based pathway intervention (n=300), the social-based pathway intervention (n=300), or the integrated intervention based on the full PW Model (both pathways; n=300) to an attention control group (n=300). We 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.
