 Problem gambling and problem drinking frequently co-occur. Further, the treatment needs of people with co-occurring gambling and drinking problems may be different from those of problem gamblers who do not drink alcohol in a hazardous fashion. The current project will evaluate whether there is a benefit to providing access to a problem drinking Internet intervention GA 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 problem drinking.
