This current project investigates the applicability and effectiveness of the CRAFT model as a tool for supporting the CSOs of problem gamblers. A comparative analysis will be completed with random assignment of 60 CSOs to either of Group A (CRAFT) or Group B (treatment as usual). Twelve individual treatment sessions will be offered to each of the CSOs. It is predicted the outcomes of from Group A (CRAFT) will significantly surpass those from Group B (treatment as usual). The predicted outcomes are: improvement in quality of life for the CSOs; engagement of the IPGs in treatment; and decreased gambling by the IPGs. All therapists in the CRAFT experimental group have been certified in the CRAFT model. A comparative analysis will be conducted with the CRAFT approach (Group A) and the traditional treatment approach (Group B). Model adherence will be supervised and tested.
