Intervention: Understanding Behaviour Change (UBC) training. UBC training is structured on the Prevention and Lifestyle Behaviour Change: Competency Framework (National Institute for Health and Clinical Excellence 2007). The training is accredited by the Royal Society for Public Health (RSPB). The training aims to enable learners to understand behaviours associated with active listening, effective hearing, reflecting, checking understanding and their use in effective communication. UBC training also identifies enabling approaches to building relationships, knowledge of behaviour change models and how to explore an individual's motivation to adopt positive health behaviours. The training will enhance the trainees' skills in supporting individuals to develop strategies to enable them to plan and implement changes in their lifestyle or health behaviour. The training is supported with role play to develop communication skills.
