Brief Alcohol and HIV Prevention for Homeless Adolescents Who Exited Foster Care

描述（由申请人提供）：本R21申请提出了一加一（OPO）的发展和试点可行性试验，这是一个创新的，理论驱动的，两节，个人层面的干预，旨在减少酒精使用，艾滋病毒性风险行为，以及在经历住房不稳定或从寄养过渡到独立生活后无家可归的大龄青少年在性活动中使用酒精。OPO将整合简短的动机和认知行为战略，以解决青少年酗酒和艾滋病毒风险行为问题，并根据个人风险因素、环境背景和准备改变的阶段，纳入减少风险的详细反馈。干预所需资源最少，易于转移到其他环境，并且不太可能遇到与较长时间、多期干预相关的损耗问题。此外，即使这种短暂的干预措施不如长期的、更密集的方法有效，但由于易于传播而增加的覆盖范围最终可能导致更大的总体公共卫生影响。

DESCRIPTION (provided by applicant): This R21 application proposes the development and pilot feasibility trial of One Plus One (OPO), an innovative, theory-driven, two-session, individual-level intervention designed to reduce alcohol use, HIV sexual risk behaviors, and the use of alcohol during sexual activities among older adolescents who experienced housing instability or became homeless after transitioning from foster care to independent living. OPO will integrate brief motivational and cognitive-behavioral strategies to address adolescent alcohol and HIV risk behaviors and incorporate detailed feedback for risk reduction that are tailored to individual risk factors, environmental context, and stage of readiness to change. The intervention requires minimal resources, is readily transferable to other settings, and should be less likely to encounter attrition problems associated with longer, multi-session interventions. Moreover, even if this brief intervention is somewhat less effective than lengthy, more intensive approaches, the increased coverage from ease of dissemination may eventually result in a larger overall public health effect. PUBLIC HEALTH RELEVANCE The proposed research aims to develop and pilot an innovative, theory-driven, two-session, individual-level intervention designed to reduce alcohol use, HIV sexual risk behaviors, and the use of alcohol during sexual activities among older adolescents who became homeless after transitioning from foster care to independent living. This is one of few studies to integrate brief motivational and cognitive-behavioral strategies to address older adolescent alcohol and HIV risk behaviors and incorporate detailed feedback for risk reduction that are tailored to individual risk factors, environmental context, and stage of readiness to change. The intervention requires minimal resources, is readily transferable to other settings, should be less likely to encounter attrition problems associated with longer, multi-session interventions, and may, therefore, eventually result in a larger overall public health effect than more intensive approaches.
