Contingency Management Using Smartphone App in Patients With SUD

Study procedures related to the DynamiCare Rewards intervention were conducted via smartphone. Research visits included collection of urine samples and medical exams. Participants assigned to the DynamiCare Rewards group received: 1) the app on their smartphone, 2) drug testing devices when indicated (pocket-sized breathalyzer), and a reloadable debit card for receiving the financial incentives (the PEX debit card). Global Positioning System (GPS) tracking was used to track whether patients had attended their scheduled appointments but was not used at any other times. All information was uploaded from the app onto the DynamiCare Analytics website, which treatment providers could view. The information reported was: attendance status of appointments, the status of all alcohol and drug testing, and incentives earned. Each patient's intervention period (period of time when they used the app) lasted four months from the date of their enrollment.
