What is the role of psychology in bariatric surgery? A survey of the differing views of psychologists, the multidisciplinary team, and patients in the UK

Although psychologists are a key member of the bariatric multidisciplinary team (MDT), there is a lack of clarity about the specific remit of their role. This exploratory study was conducted to identify differences, priorities and clarify how the role of psychology is perceived in the United Kingdom. We conducted surveys of three major stakeholder groups (psychologists, patients, and the bariatric multidisciplinary team) which focused on their perception of psychology in bariatric surgery. The results showed that in UK bariatric services, psychologists are spending the majority of their clinical time providing pre-operative assessments. Differences emerged between psychologists and MDT in how they viewed the purpose of these assessments, with the MDT viewing them as identifying contraindications to surgery whereas psychologists viewed them as identifying readiness for surgery. A total of 51% of patients reported they had not been able to access psychology services when needed and viewed provision of post-operative psychological support to be a key priority. Key themes and tensions emerged around (a) high demand for services yet limited psychology resource, (b) the purpose of the pre-operative assessment and (c) the provision of pre-operative versus post-operative support. These themes combine and interact in a way that currently makes it extremely challenging to provide coherent psychology services. There is clearly a need for education, consensus and adequate resourcing of the psychology role within bariatric surgery services in the United Kingdom.
