This Project Grant award from the National Institute on Drug Abuse (NIDA), under the Drug Use and Addiction Research Programs (CFDA 93.279), aims to comprehensively validate the PINK CLOUD digital platform, a mobile health application that provides substance use disorder (SUD) and alcohol use disorder (AUD) recovery support. The $980,000 award to PINK CLOUD, Inc. will fund a two-phase initiative. The first phase will enhance the app with new features to improve user experience and marketability, including automated meeting attendance tracking, provider search functionality, and a 12-step AI chatbot. The second phase will conduct a randomized controlled trial with 1,410 participants to evaluate whether access to the PINK CLOUD app can influence the duration of sobriety and reduce substance use problems over a 6-month period. The study will also analyze user engagement factors that may predict participant interactions with the app's features.
