Clinical Trial Summary

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.

Intervention

Behavioral:
• 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	App usage (feasibility)	Number of days the app is active on a user's smartphone. Days can range from 0 to 84.	From baseline to post-treatment (12 weeks)
Primary	Patient satisfaction with the gambling app	Investigator derived patient satisfaction self-report questionnaire. Five items, using a 7-point Likert scale from very dissatisfied (1) to very satisfied (7). Higher scores indicate a better outcome.	From baseline to post-treatment (12 weeks)
Secondary	Gambling behavior via Timeline Followback (Weinstock, Whelan, & Meyers, 2004)	Self-report gambling frequency and intensity as assessed by the Gambling Timeline Followback - a retrospective self-report calendar. Gambling frequency can range from 0 to 84; gambling intensity is measured in $ and time (hours). Dollars wagered can range from $0 to unlimited $. Time is measured in hours and can range from 0 to >1,000 hours. Higher scores indicate a worse outcome.	From baseline to post-treatment (12 weeks)
Secondary	Gambling-related harms (Browne et al., 2018)	Self-reported gambling harms as assessed by the 72-item Gambling-Related Harms Questionnaire (yes/no responses). Scores range from 0 to 72. Higher scores indicate a worse outcome.	From baseline to post-treatment (12 weeks)
Secondary	Quality of Life Inventory (Frisch et al., 1994). A self-reported quality of life measure assessing 17 domains of life for importance and satisfaction.	Self-report quality of life questionnaire. Participants rate 17 domains on importance (range not at all important [0] to extremely important [2]). The 17 domains are then rated on how satisfied the individual is regards to his or her life (-3 [very dissatisfied] to 3 [very dissatisfied]). A total score is then generated by summing the product of importance multiplied by satisfaction. Scores range from 0 to 102. Higher scores indicate a better outcome.	From baseline to post-treatment (12 weeks)
