A Brief Intervention for Young Adult Substance Users With Interpersonal Trauma

This proposal seeks to improve a mobile-based brief intervention for young adults who engage in heavy alcohol use and have experienced interpersonal trauma. The enhancement involves incorporating adaptive coping strategies to address trauma-related distress and engaging peer coaches following the intervention to support sustained treatment effects. Participants will be randomly assigned to receive either the enhanced intervention with peer coaching or a standard version of the brief intervention. Follow-up assessments will be conducted at 3 and 6 months after the intervention. The research team expects that the trauma-informed and peer-supported brief intervention (TIPS-BI) will have low dropout rates, be well-received by participants, and lead to greater reductions in alcohol use than the standard brief intervention.
