简要总结
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.

结局指标
主要结局
Perceived Program Effects on Healthy Relationship Self-Efficacy items
时间窗: Screening, baseline, approximately 5 weeks after baseline, 3-month followup
Healthy relationship self-efficacy - 3 items assessing perceived intervention impacts on healthy relationship self-efficacy scored 0=strongly disagree to 5=strongly agree. Scores will be summed, total scores will range from 0 to 15, with higher scores indicating greater healthy relationship self-efficacy
Couples Satisfaction Index
时间窗: Screening, baseline, approximately 5 weeks after baseline, 3-month followup
Relationship satisfaction - sum of 4 items ranges from 0 to 21, higher scores indicate greater relationship satisfaction
Intensity of Marijuana Use
时间窗: Screening, baseline, approximately 5 weeks after baseline, 3-month followup
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
Heavy episodic and high intensity drinking
时间窗: Screening, baseline, approximately 5 weeks after baseline, 3-month followup
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)
时间窗: Screening, baseline, approximately 5 weeks after baseline, 3-month followup
Alcohol use - Average total drinks per week will be calculated as the sum of the total number of drinks reported.
Daily Marijuana Questionnaire (DMQ)
时间窗: Screening, baseline, approximately 5 weeks after baseline, 3-month followup
Cannabis use - Average total hours high from cannabis per week will be calculated as the sum of the total hours high reported
