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.
