Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this project is to develop and to test the efficacy of a novel mHealth app for gambling disorder. The app capitalizes on smartphones' global positioning software (GPS) that recognizes a user's location to within 15 feet. Users will receive an alert of this go near a gambling venue. The project will conduct a 12-week pilot randomized clinical trial to test the short-term efficacy of the app with gambling disorder individuals.

mHealth App

Participants will receive the gambling disorder mHealth app.

Group Type EXPERIMENTAL

mHealth App

Intervention Type BEHAVIORAL

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.

Group Type NO_INTERVENTION

No interventions assigned to this group
