Computerized Interventions for Stress in Cannabis Users
This study is evaluating two brief, computerized interventions for stress in young adults (ages 18-30) who use cannabis regularly and have Cannabis Use Disorder (CUD). One intervention, called Emotional Engagement Distress Tolerance Intervention, helps you build tolerance to difficult emotions. The other, Health Education Intervention, focuses on healthy habits for managing stress. Researchers want to see if these interventions can reduce how much distress you feel and improve your cannabis use. To join, you must have a CUD diagnosis, use cannabis almost daily, and have high levels of distress intolerance (difficulty handling upsetting feelings). Your urine will be tested for THC. The study aims to enroll 80 participants, but its current status is unclear.
- Study design
- This is an interventional study comparing two behavioral interventions. It plans to enroll 80 participants.
- What's involved
- You will participate in a 2.5-hour computerized intervention with smartphone support. You will also complete questionnaires immediately after the intervention, and then 10 days, 20 days, one month, and four months later.
- Compensation
- Not stated in the trial record.
- Follow-up
- Participants will be followed for four months after the intervention session.

What this trial measures
- Therapy Evaluation QuestionnaireImmediately after intervention session
acceptability/feasibility (credibility subscale range 3-27; expectancy item range 0%-100%; higher scores indicate better outcome)
- Treatment Satisfaction QuestionnairePost-Intervention (20 days after intervention session)
acceptability/feasibility (range 0-84; higher scores indicate better outcome)
- Change in perceived distress intolerance from baseline through follow-upBaseline, Mid-Intervention (10 days after intervention session), Post-Intervention (20 days after intervention session), One-Month Follow-up, Four-Month Follow-up
Distress Intolerance Index (range 0-40; higher scores indicate worse outcome) to assess perceived distress intolerance via self-report
- Change in behavioral distress intolerance from baseline through follow-upBaseline, Mid-Intervention (10 days after intervention session), Post-Intervention (20 days after intervention session), One-Month Follow-up, Four-Month Follow-up
Mirror-Tracing Persistence Task to assess behavioral distress intolerance via computerized task
- Change in laboratory stress-induced cannabis craving from baseline through post-interventionBaseline, Post-Intervention (20 days after intervention session)
Change in Marijuana Craving Questionnaire (range 11-77; higher scores indicate worse outcome) after Mannheim Multicomponent Stress Test at post-intervention compared to baseline
- Change in laboratory stress-induced neural reactivity to cannabis cues (assessed via the electroencephalography [EEG]-recorded late positive potential) from baseline through post-interventionBaseline, Post-Intervention (20 days after intervention session)
Change in Late Positive Potential to Cannabis Cues after Mannheim Multicomponent Stress Test at post-intervention compared to baseline

- Change in self-reported cannabis use problems from baseline through follow-upBaseline, Post-Intervention (20 days after intervention session), One-Month Follow-up, Four-Month Follow-up
Change in Marijuana Problems Scale (range 0-38; higher scores indicate worse outcome) from baseline through follow-up
- Change in Cannabis Use Disorder symptoms from baseline through follow-upBaseline, Four-Month Follow-up
Change in interviewer-assessed Cannabis Use Disorder criteria (range 0-11; higher scores indicate worse outcome) from baseline to four-month follow-up
- Change in Cannabis Demand from baseline to post-interventionBaseline, Post-Intervention (20 days after intervention session)
Change in Omax, Breakpoint, and Elasticity derived from Marijuana Purchase Task (higher OMax/Breakpoint and lower Elasticity indicate worse outcome) at post-intervention compared to baseline
