Smartphone Services for Stimulant Use Disorder

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.
