Behavioral ApproachSmartphone Services for Stimulant Use Disorder

The main thing participants will do is use an app on their smartphone that might help with recovery. The most important feature of the app is that it allows participants to take a video selfie of themselves taking saliva (spit) drug tests. Then, the app will send these videos to the investigators in a way that is secure and protected. The app also has self-assessments \& reading materials that may be of interest to participants. The intervention group will have an appointment and call tracking module and self-guided CBT therapy modules. The DynamiCare group will be able to report the data collected to their providers and will be able to share the app with people who support them.

This intervention is composed of a smartphone app (Apple iOS or Android type) that prompts patients with Stimulant Use Disorder to (1) complete self-assessment questionnaires in the app about their health, health care needs and the services they receive and other health-related functions in life, (2) read educational modules about health and wellness and answer questions about these readings, (3) speak periodically with a Guide about their use of the app, and (4) take periodic saliva substance tests using video-selfies with their smartphone camera. The intervention includes testing and interviews with the study staff over a 12 month period. There is a follow-up period to measure the longer-term results at 15 months, as well.
