This study will develop and assess acceptability and feasibility of a multifaceted behaviour change intervention. The intervention will be designed to train healthcare professionals to use behavioural strategies to target key lifestyle behaviours in the context of liver transplantation, and to equip patients with behavioural skills to make positive changes to a range of lifestyle behaviours. In reality, this could be the most cost effective model to be able to enable lifestyle change for transplant patients. These healthcare professionals are front line staff and work with high volumes of transplant patients.
