Web-based Family Prevention of Alcohol and Risky Sex for Older Teens

描述（由申请人提供）：有必要对从事酒精和/或性危险行为的年龄较大的青少年（16-17岁）进行干预。年龄较大的青少年变得更加自主，父母的角色变得更加困难，因为他们在提供指导的同时放弃控制。家长们在监督和指导的正确组合中挣扎。如果以家庭为基础的解决这些青少年行为的方法是有效的，这个新项目可能会为改善年长青少年的健康和安全提供一个低成本和重要的策略。本研究将针对16-17岁青少年及其父母开发一种基于网络的干预方法。具体目标1：调整两种以家长为基础的预防策略（家庭事务和家长手册），以提供一种以家庭为基础的方法，以解决年龄较大的青少年与酒精有关的风险行为和性风险行为以及与酒精结合的性行为（以下称为酒精和/或性风险行为）。具体目标2：测试接触该项目是否会导致目标青少年的信仰和行为发生预期的变化，包括减少酒精和/或性风险行为。具体目标3：研究项目对青少年酒精和/或性风险行为的影响是否通过中间项目目标信念（父母和青少年）和行为（父母-青少年-沟通）的改变来调节。程序保真度和过程度量也可能调解这些结果。第一阶段整合和调整两种基于家长的方法，并创建基于网络的交互式材料交付。专家小组、焦点小组和可用性评估将为整个过程提供信息。第二阶段是对500个家庭进行基于网络干预的随机对照试验。调查将在基线进行，并进行三个随访期（6、12和18个月）。分析将检查与酒精和/或性危险行为有关的青少年结果。对青少年和家长直接影响的调解人的变化将被检查。过程和保真度信息将被收集和评估。

DESCRIPTION (provided by applicant): There is a need for interventions for older teens (16-17) who are engaging in alcohol and/or sexual risk behaviors. Older teens become more autonomous and the role of the parent becomes more difficult as they balance providing guidance while relinquishing control. Parents struggle with the right mix of monitoring and guidance. If a family-based approach to address these teen behaviors is effective, this new program could potentially provide a low cost and important strategy for improving the health and safety of older teens. This study will develop a web-based intervention for 16-17 year old youth and their parents. The aims are as follows: Specific Aim 1: To adapt two parent-based prevention strategies (Family Matters and Parent Handbook) to provide a family-based approach for addressing older teen alcohol related risk behaviors and sexual risk behaviors and sex in combination with alcohol use (hereafter called alcohol and/or sexual risk behaviors) using the web as the program delivery mode. Specific Aim 2: To test whether exposure to the program leads to expected changes in targeted teen beliefs and behaviors, including reductions in alcohol and/or sexual risk behaviors. Specific Aim 3: To examine whether program effects on teen alcohol and/or sexual risk behaviors are mediated through changes in intermediate program targeted beliefs (parents and teen) and behaviors (parent-teen--communication). Program fidelity and process measures may also mediate these outcomes. Phase I integrate and adapt the two parent-based approaches and creates a web-based interactive delivery of materials. Expert panels, focus groups, and usability assessments will inform the process. Phase II is an RCT with 500 families with the web-based intervention. Surveys will be conducted at baseline, and for three follow-up periods (6, 12, & 18 months). Analyses will examine teen outcomes related to alcohol and/or sexual risk behaviors. Changes in mediators directly impacted by the program for both teens and parents will be examined. Process and fidelity information will be collected and assessed.
