The goal of this clinical trial is to develop and test a brief online intervention to reduce alcohol and cannabis misuse and improve healthy relationship skills among young adult couples. The main questions it aims to answer are:
* Will the intervention be feasible and acceptable to young adult couples? * Will the intervention demonstrate initial efficacy in reducing risky substance use and increasing relationship functioning?
Eligible couples will complete a virtual baseline session and be randomized to intervention condition (online intervention with 3-5 weeks of self-paced modules) or control condition (no intervention). Couples will complete two follow-up surveys (post-assessment - approximately 5 weeks after baseline, 3-month). Couples in the control condition will be offered the intervention after 3-month follow-up.
Researchers will compare intervention and control groups to see if there there is a difference between the groups on substance misuse and relationship functioning at post-assessment and 3-month follow-up.
Both partners in the couple are 18-29 years old
In a committed romantic relationship (e.g., dating seriously, cohabiting, married) with each other for at least 3 months
Face-to-face contact their partner at least 5 days per week
Live in Washington State
Couples who endorse any perpetration or receipt of severe interpersonal aggression during screening will be excluded and provided with resources
Parallel
Online, couples-based intervention
BehavioralDuring 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).
Heavy episodic and high intensity drinking
Alcohol use - number of days in the past month participant engaged in heavy episodic drinking (4+/5+ drinks in one occasion for women/men) and high intensity drinking (8+/10+ drinks in one occasion for women/men)
Daily Drinking Questionnaire (DDQ)
Alcohol use - Average total drinks per week will be calculated as the sum of the total number of drinks reported.
Daily Marijuana Questionnaire (DMQ)
Cannabis use - Average total hours high from cannabis per week will be calculated as the sum of the total hours high reported
Intensity of Marijuana Use
Cannabis use intensity - Average number of times used cannabis per day will be calculated as the mean number of times participant reports using cannabis per each day of a typical week in the past month
