This rapid evidence review was commissioned by Great Britain's Gambling Commission to provide an updated evidence base on treatment and support for problem gambling, to inform future growth, improvement, and evaluation of problem gambling treatment services. The review summarizes recent evidence on the overall effectiveness of several treatment modalities. Where available, it identifies which key populations may benefit from specific treatment modalities and how modalities can be structured to meet the needs of specific patient groups. It also aims to identify major gaps in the evidence and what considerations should be taken into account when evaluating and improving provision of treatment services.

The report covers ten key treatment topics:

• Cognitive behavioural therapy
• Motivational interventions
• Remote and self-help interventions
• Helplines
• Treatment involving concerned significant others
• Residential treatment
• Pharmacological treatments
• Brain stimulation
• Gamblers anonymous
• Emerging treatment modalities
