Online Interventions for Gamblers With and Without Co-occurring Mental Health Concerns

Online Interventions for Problem Gamblers With and Without Co-occurring Mental Health Concerns: Randomized Controlled Trial

Comorbidity between problem gambling and mental health concerns such as anxiety and depression is common. Further, the treatment needs of people with co-occurring gambling and mental health concerns may be different from those of problem gamblers who do not have a co-occurring mental health concern. The present study is a two-arm, double blinded, parallel group randomized controlled trial (RCT) that will evaluate whether there is a benefit to providing access to mental health Internet interventions (G+MH intervention) in addition to an Internet intervention for problem gambling (G-only intervention) in participants with gambling problems who do or do not have co-occurring mental health concerns.

Study Overview

• Status: Completed
• Conditions: Depression; Anxiety; Gambling
• Intervention / Treatment: Behavioral: Gambling Internet intervention; Behavioral: MoodGYM

Detailed Description

People with gambling concerns will be recruited using targeted advertisements. Potential participants will be screened using an online survey to identify participants meeting criteria for problem gambling. As part of the baseline screening process, measures of current depression and anxiety will be assessed. Eligible participants agreeing to take part in the study will be randomized to one of two versions of an online intervention for gamblers - an intervention that just targets gambling issues (G-only) versus one that contains interventions for anxiety and depression in addition to an intervention for gamblers (G+MH). It is predicted that problem gamblers who do not have co-occurring mental health concerns will display no significant difference between intervention conditions at a six-month follow-up. However, for those with co-occurring mental health concerns, it is predicted that participants receiving access to G+MH website will display significantly reduced gambling outcomes at six-month follow-up as compared to those provided with G-only website.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Gambling Internet intervention; The gambling only Internet intervention (G-only) will consist of a new online version of self-change tools that have previously been translated successfully into an online form and shown to have a significant impact on gambling in three trials. A major focus of this intervention is to provide individuals with clear and concise behavioral and cognitive strategies for meeting the goal of reducing or quitting gambling.

Experimental: Gambling Internet intervention + MoodGYM; The G+MH intervention condition will consist of the G-only intervention and an online intervention for depression and anxiety. The mental health intervention chosen is MoodGYM, an extensively evaluated intervention found to be effective in a variety of different settings.
