The usefulness and feasibility of contingency management (CM) for treating gambling disorder has not been a topic of much research. CM works by rewarding target behaviours, such as abstaining from gambling. The aim of this study was to investigate what treatment providers thought of using CM to treat gambling disorder. 30 treatment providers in the UK learned about CM and were asked what they thought the benefits and limitations of this approach were. The authors identified four themes from the interviews. The first theme was that CM did not align with personal treatment philosophies, but participants were open about it. The second theme was concern about CM’s perceived similarity to gambling. The third theme was the concern that CM could be manipulated and rupture the therapeutic alliance. The fourth theme was about how CM might be implemented and delivered.
