Summary
This randomized controlled trial (RCT) will evaluate the feasibility and efficacy of Pink Cloud, a mobile health application designed to support recovery from substance and alcohol use disorders (SUD/AUD). The app provides access to over 245,000 in-person and virtual 12-Step meetings, along with features such as a sobriety counter, daily planner, and personal inventory tools. In this study, 1,410 participants in various stages of recovery will be randomly assigned to receive either access to the Pink Cloud app or to a control condition. Participants will complete follow-up assessments at 1, 3, and 6 months. Primary outcomes include number of days sober and frequency of drug and alcohol problems. Secondary outcomes include meeting attendance, proportion of sober individuals in one's social network, and engagement in recovery-related activities. The investigators hypothesize that participants in the Pink Cloud group will report more days sober and fewer substance use problems than those in the control group, and that they will also report attending more meetings, having a greater proportion of sober peers, and engaging more frequently in recovery activities.
