This study aims to develop and test a theory-based motivation communication training programme for healthcare professionals working with diabetic foot ulcer patients. The investigators will explore the acceptability of the training programme and examine whether the training leads to changes in healthcare professionals' communication style, and results in greater adherence to treatment recommendations (i.e., reduced weight-bearing) in patients.

This is a proof of concept, two-arm non-randomised, controlled before-and-after study. Patient outcomes (perceptions of healthcare professional communication style, treatment self-regulation and adherence to activity reduction) will be collected first during a control/usual care period. Healthcare professionals will then receive the theory-based motivation communication training programme. Subsequently a new group of patients will be recruited as the intervention group and the same outcome measures collected. Control group outcomes will be compared to intervention group outcomes. Interviews will be conducted with healthcare professionals and patients to assess acceptability of the intervention.
