In England, there are almost 1.6 million adults who participate in harmful gambling who may benefit from some type of treatment or support for harmful gambling.

Of these, the majority (970,000) might benefit from a ‘level 2 intensity’ treatment, which typically involves 2 or 3 sessions of motivational interviewing delivered by gambling-specialist practitioners. Around 243,000 adults might benefit from a ‘level 4 intensity’ treatment, which typically involves 8 to 14 sessions of psychologist-led cognitive behavioural therapy (CBT) for gambling disorder.
