Developing and Testing an Online Intervention for Alcohol and Cannabis Misuse and Healthy Relationship Skills Among Young Adult Couples

During Phase 1 of the present study, the intervention will be iteratively developed using a rigorous, user-centered design approach through integration of knowledge gained from Phase 1 dyadic analyses and qualitative interviews, and existing gold-standard treatments for substance use among couples, including Integrative Behavioral Couples Therapy (IBCT; Christensen \& Doss, 2016) and Behavioral Couples Therapy for Alcohol (ABCT; McCrady et al, 1995) and substance use brief interventions for young adults (Halladay, et al., 2019; Tanner-Smith et al., 2015).
