Not Applicable

• Conditions: Gambling, Pathological; Anger

• Registration Number: NCT00345527
• Lead Sponsor: Centre for Addiction and Mental Health

Brief Summary

Despite evidence of high rates of concurrent substance use and anger problems among problem gamblers, until recently there have been no empirically evaluated treatments for these co-morbid problems. A recent study (Korman, Collins, McMain, \& Skinner, 2005) found that an emotion and behaviour regulation treatment (EBRT) was more effective than a gambling-only treatment-as-usual in engaging clients in treatment and in reducing gambling, anger, and substance use. This study is a replication of Korman et al's study and will compare an emotion and behaviour regulation treatment (EBRT) for problem gambling, anger and substance use to a manualized cognitive behavioural treatment (CBT) for problem gambling.

Detailed Description

80 participants will be randomly assigned to either an emotion and behaviour regulation treatment (EBRT) or to a cognitive behavioural treatment (CBT). Randomization will be stratified by the presence of substance dependence disorder. Both treatment conditions will consist of 12 one-hour weekly outpatient individual sessions. Participants will be assessed at baseline, end of treatment, and 3-months, 6-months and 12-months follow-up.
