Detailed Description:

Pathological gambling has become an increasingly problematic condition in the United States, often causing serious financial, psychological, and public health consequences. In an effort to treat this growing problem, researchers have evaluated numerous therapies; one such therapy is CBT. CBT has been shown to improve pathological gambling outcomes. However, evidence suggests that adding CM to CBT could result in even more improved outcomes. This study will compare the effectiveness of CBT and CM with that of CBT alone in reducing pathological gambling.

This study will last 12 months. Participants will be randomly assigned to receive either CBT and CM or CBT alone for 8 weeks. CBT will focus on reducing gambling urges and helping patients develop alternative behaviors to gambling. CM will focus on encouraging patients to avoid gambling. Participants in the CBT and CM group will receive voucher incentives for completing homework assignments and engaging in non-gambling social activities. The vouchers will allow participants to take part in non-gambling activities of their choice. Changes in gambling activities and problems will be assessed with self-report scales and interviews at study start and at Weeks 10, 24, and 52.

Participants will be asked to identify at least one person who knows about their gambling and will have regular contact with them over the 12 months of the study. This person will be interviewed at study start and at Months 2, 6, and 12. Contact persons will be asked about participants' gambling behaviors, personal relationships, legal problems, use of health care and mental health services, and how the participant can be contacted if he or she moves.
