Marijuana and alcohol use are associated with increased sexual risk behavior among justice-involved youth. A multi-behavior intervention may reduce all three risk behaviors.
To examine the relationships among multiple risk behaviors and the Theory of Planned Behavior (TPB) constructs guiding the development of the MARS (Motivating Adolescents to Reduce Sexual risk) intervention. We describe the MARS study design to inform the process through which a multi-behavior intervention trial can be implemented and evaluated.
Participants completed questionnaires prior to randomization to one of three interventions.
Relationships were found between TPB constructs and risk behavior. A single latent variable was inadequate to capture all three risk behaviors.
Interventions to reduce sexual risk behavior can include content related to the role of substance use in influencing sexual risk behavior with only minimal modifications to the curriculum, and preliminary data suggest a common theory can apply across risk behaviors.
大麻和酒精的使用与涉司法青少年性风险行为的增加有关。多行为干预可能会减少所有这三种风险行为。
研究多种风险行为与指导“激励青少年降低性风险”（MARS）干预措施制定的计划行为理论（TPB）结构之间的关系。我们描述了MARS研究设计，以为多行为干预试验的实施和评估过程提供信息。
参与者在随机分配到三种干预措施之一之前完成问卷调查。
发现TPB结构与风险行为之间存在关联。单一潜在变量不足以涵盖所有三种风险行为。
减少性风险行为的干预措施可以包括与物质使用在影响性风险行为中的作用相关的内容，只需对课程进行最小程度的修改，并且初步数据表明一种通用理论可以适用于多种风险行为。
