People with problem gambling who are in the criminal justice system would benefit from treatment for their gambling. However, little is known about how to best treat this population. Sixteen experts were interviewed to gain knowledge about gambling treatment in correctional settings. Three key issues were examined: 1) barriers to treatment, 2) gender differences in treatment, 3) how to best implement treatment. Several themes were identified for each issue and discussed in detail. One key finding was that there is a lack of awareness of problem gambling within correctional settings. Several recommendations were made to improve treatment in these environments.
