Project MARS: Design of a Multi-Behavior Intervention Trial for Justice-Involved Youth.

ABSTRACT:

Background

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.

Purpose

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.

Methods

Participants completed questionnaires prior to randomization to one of three interventions.

Results

Relationships were found between TPB constructs and risk behavior. A single latent variable was inadequate to capture all
