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.

描述（由申请人提供）：拟议的研究将检验基于网络的个性化反馈干预措施，以减少 18-20 岁未成年饮酒者中与酒精相关的危险性行为，理论上这是由原型意愿模型提供的。基于针对青少年和年轻人的适合发育的健康模型的文献，原型意愿模型假设了两种危险行为途径：一种是理性途径，另一种是基于社会的途径。先前的研究表明，与原型意愿模型一致的干预措施，或基于原型意愿模型组成部分的干预措施，可以有效减少饮酒和危险性行为。尽管该模型很实用，但仍有待完善 应用于检查由 PW 模型两种途径组成的干预措施是否能有效减少未成年饮酒者与酒精相关的危险性行为。此外，还没有研究检验过该模型的活性成分（理性途径与社会途径）。本申请中提出的研究旨在评估基于原型意愿模型的个性化反馈干预措施，通过对通过社交网站招募的全国年轻人（大学和非大学）样本进行纵向研究，重点关注与酒精相关的危险性行为。为了实现这一目标，该研究将在全国范围内招募 1,200 名 18-20 岁的年轻人样本，并对他们进行 3 个月、6 个月、9 个月和 12 个月的评估。我们将通过比较随机分配接受基于推理的途径干预（n=300）、基于社会的途径干预（n=300）或基于完整 PW 模型（两种途径；n=300）的综合干预的未成年饮酒者与注意力对照组（n=300），评估基于原型意愿模型的干预措施的总体效果。我们将研究理性途径和社会途径组成部分的变化以及饮酒是否介导干预措施对减少酒精相关危险性行为的功效。过去的行为和大学生状况将被评估为干预效果的调节因素。拟议的研究既重要又具有创新性，因为它将评估全国上大学和未上大学的年轻人样本中的简短干预措施，将利用社交网站招募参与者，并将测试基于原型意愿模型的个人和综合路径的干预措施的有效性。
