Overview

The purpose of this research study is to determine the effectiveness of the Change4Better (C4B) mobile app at reducing the severity of problem gambling as compared to standard treatment as usual (TAU).

Description

This study is a 6-month randomized clinical trial for individuals with a gambling disorder enrolled in or seeking treatment for problem gambling at an outpatient treatment facilities affiliated with the Bettor Choice Gambling Treatment Programs in Connecticut. The purpose is to evaluate the feasibility and efficacy of a cognitive behavioral therapy-based mobile app (Change4Better; C4B), as an adjunct to treatment as usual (TAU) in community-based outpatient treatment programs. Eligible participants will be randomly assigned to receive either: (1) standard treatment as usual (TAU) or (2) TAU plus access to the Change4Better (C4B) mobile app. TAU will consist of standard services provided at outpatient clinics within the Bettor Choice Programs. Clinicians providing TAU within the Bettor Choice Program will not be participants in the research trial, and they will not be asked to perform any additional duties outside of their typical services. Participants assigned to C4B will receive TAU plus access to the C4B mobile app, which they can access as often as desired using their own device. The C4B mobile app will be managed by the Yale research team.
