Evaluation of a Brief Computerized and Smart Phone-based Intervention for Stress in Regular Cannabis Users

The prevalence of daily cannabis use and Cannabis Use Disorder (CUD) has increased in the United States over the past two decades. Brief, computerized harm reduction interventions that target specific high-risk CUD populations could be an efficient approach to reducing CUD. Distress intolerance , which refers to the tendency to negatively appraise and escape aversive emotional states, is a risk factor associated with stress-related cannabis use motivation and CUD severity/chronicity. Thus, a brief, accessible, low-cost intervention that reduces distress intolerance in those with CUD and elevated distress intolerance could have a significant public health impact. This proposed project aims to optimize an existing two-session computerized distress tolerance intervention and test its impact on distress intolerance and cannabis use outcomes in a randomized controlled trial. Specifically, the intervention will be condensed to one-session, its active ingredient bolstered, and augmented with smart phone-delivered therapy reminders. After obtaining feedback on the modified Emotional Engagement Distress Tolerance Intervention in a small sample, the intervention's efficacy compared to a stringent, credible, time-matched health education control intervention will be tested in a randomized controlled trial in 80 cannabis users with CUD and high distress intolerance. Distress intolerance, cannabis use, and psychosocial functioning outcomes will be evaluated. As an exploratory aim, a wrist…
