Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
mHealth App
Participants will receive the gambling disorder mHealth app.
mHealth App
The app uses smartphones' global positioning software (GPS) that recognizes a user's location to within 15 feet. The app will construct a customizable geofence (e.g., 3 miles) around a gambler's favored gambling venue (e.g., casino, gas station). If the individual crosses the fence boundary his or her phone will raise the alarm with a personalized motivational message.
Wait List Control
Participant will be placed on a wait list for 12 weeks, after which they will be offered the gambling disorder mHealth app.
