About this course
Behavioural addiction shares similarities with substance-related addiction but it concerns a rewarding activity, such as gambling or gaming. This webinar presents an overview of the growing field of behavioural addiction and discusses why certain behaviours are considered addictions. It summarises influential models and theories, shedding light on the psychology of addictive behaviour, and warning against the danger of pathologizing common behaviours. As the treatment for behavioural addiction is evolving, the webinar focuses on the evidence-based treatment for gambling harms, the first officially recognised form of behavioural addiction.
The National Gambling Clinic (NGC) and Central and North West London (CNWL) NHS Foundation Trust have offered evidence-based treatment for gambling harms since 2008. With the need for a public health approach to gambling harms being increasingly recognised (Goyder, Blank, Baxter, & van Schalkwyk, 2020), the NHS now funds treatment for those experiencing such harms across England. This webinar presents the service model developed at the NGC, the first NHS clinic treating gambling harms.
It also presents the CBT treatment protocol adapted and refined by the clinic over the years. The CBT protocol, published in a self-help book (Bowden-Jones & Leonidaki, 2022), is at the heart of the treatment programme. Delivered by a leading clinical psychologist, this training event also explains the role of integrating systemic and relational factors in the treatment of gambling harms. The treatment principles presented here may be relevant, at least to some extent, to other forms of behavioural addiction.
This course is free to CNWL staff. Please contact us on cnwl.step-up@nhs.net before booking for more details.
