Behaviour change for type 2 diabetes: perspectives of general practitioners, primary care academics, and behaviour change experts on the use of the 5As framework

Lay Summary General practitioners (GPs) are usually involved in helping patients with diabetes to improve their diet, physical activity, and other lifestyle behaviours. The 5As are a framework designed to be used to structure behaviour change conversations-5As stand for Ask, Assess, Advise, Assist, and Arrange. We interviewed 20 people who were either GPs or experts in behaviour change. They had different ways of explaining the intent and usage of the 5As but consistently saw them as a framework for new practitioners. No one used the 5As consciously in their consultations with patients. The participants had multiple suggestions for how the 5As could be enhanced to support better care for patients living with diabetes. These included: more focus on motivational interviewing techniques, changing the number or order of the 5As steps, more focus on teamwork as well as the individual cultural needs of the patients. This work can inform further research on how patients can be better supported by GPs through evidence-based behaviour change care. Background The 5As framework is a recognized underpinning of behaviour change guidelines, teaching, and research in primary care. Supporting patients to improve their lifestyle behaviours, including diet and physical activity, is a common aspect of type 2 diabetes mellitus (T2DM) management. The 5As framework often informs behaviour change for patients with T2DM. Objective To explore the experience and perspectives of general practitioners (GPs) and primary care academics and behaviour change experts regarding using the 5As framework when caring for patients with T2DM to better understand how and why the 5As are effective in practice. Methods We recruited 20 practising GPs, primary care academics, and behaviour change experts for an individual semistructured interview and analysed the data using a realist evaluation approach. Results There were diverse accounts of how GPs use the 5As in practice and few of the participants could name each "A." The 5As were commonly regarded as a framework best suited to beginners and although GPs expressed they followed the broad direction of the 5As, they did not consciously follow the framework in an instructive manner. Elements that could enhance the 5As included more emphasis on motivational interviewing, changing how "Ask" is included in the consultation, and increased person-centredness. Conclusion Although it is a ubiquitous framework in primary care, the 5As are understood in diverse ways and applied variably in practice. There is room to enhance how the 5As support behaviour change consultations to optimize outcomes in primary care.
