The main questions it aims to answer are:\n\n* Will the intervention be feasible and acceptable to young adult couples?\n* Will the intervention demonstrate initial efficacy in reducing risky substance use and increasing relationship functioning?\n\nEligible 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.\n\nResearchers 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.",[62,63,64],"Alcohol Drinking","Cannabis Use","Couples",[66],"alcohol use, cannabis use, couples, healthy relationships, young adults","NOT_YET_RECRUITING","2026-05-04",{"date":70,"type":71},"2026-05-06","ACTUAL",{"date":73,"type":56},"2026-09-15",{"date":75,"type":56},"2027-08-01",{"name":5,"class":6}]
