## Arms

- **Psychological preparation** (ACTIVE_COMPARATOR) — Patients undergo 3 seminar sessions with the bariatric psychologist prior to their surgery. These will aim to prepare them for the lifestyle changes that will occur / they will have to make after surgery
- **Surgery as usual** (NO_INTERVENTION) — Patients will proceed to surgery as usual. They will complete psychological assessment forms at their follow up clinic sessions.

Give information about lifestyle changes after surgery. Presents the model of 'stress' and how it influences 'overeating', to develop a more balanced lifestyle and better QoL.

Session 2: 'Intervention' using Compassion Focussed Therapy model to understand relationship to food from their diary. Help develop a 'minimising overeating plan' (a 'relapse prevention' plan). Help learn to meet needs in other ways than food.

Session 3: Focus on physical body. Current body image, explore hopes and expectations for after surgery. Consider how to manage changes to social reactions and sexual relationships that may occur.

## Primary Outcomes
