Informing Alcohol-Related Risk Intervention with the Prototype Willingness Model

该研究将研究一种基于网络的个性化反馈干预，以减少18-20岁未成年饮酒者中与酒精相关的危险性行为，这在理论上是由原型意愿模型提供的。基于关注青少年和年轻人发展适当的健康模型的文献，原型意愿模型假设风险行为有两条途径：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，在减少饮酒和危险性行为方面是有效的。尽管这种模式的实用性，它还没有被 应用于检查是否干预措施组成的组件从两个途径的PW模型是有效的，在减少酒精相关的危险性行为的未成年人饮酒。此外，没有研究已经检查了这个模型的积极成分（推理途径与社会途径）。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，通过对通过社交网站招募的年轻人（大学和非大学）的全国样本进行纵向研究，重点关注与酒精相关的危险性行为。为了实现这一目标，该研究将招募1,200名年龄在18-20岁之间的年轻人，并在3个月、6个月、9个月和12个月时对他们进行评估。我们将评估基于原型意愿模型的干预措施的总体疗效，方法是将随机分配接受基于理性的途径干预（n=300）、基于社会的途径干预（n =300）或基于完整PW模型的综合干预（两种途径; n=300）的未成年年轻成年饮酒者与注意力控制组（n=300）进行比较。我们将研究理性途径和社会途径的组成部分以及饮酒是否对减少酒精相关的危险性行为的干预效果起中介作用。过去的行为和大学生身份将被评估为干预效果的调节因子。拟议的研究是既重要又创新的，因为它将在全国样本的年轻人参加和不参加大学评估简短的干预措施，将利用社交网站的参与者招募，并将测试干预措施的有效性的基础上个人和综合途径的原型意愿模型。

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.
