Abstract

AIMS: Self-management programmes for type 1 diabetes, such as the UK's Dose Adjustment for Normal Eating (DAFNE), improve short-term clinical outcomes but difficulties maintaining behavioural changes attenuate long-term impact. This study used the Behaviour Change Wheel (BCW) framework to revise the DAFNE intervention to support sustained behaviour change. METHODS: A four-step method was based on the BCW intervention development approach: 1) Identifying self-management behaviours and barriers/enablers to maintaining them via stakeholder consultation and evidence synthesis, and mapping barriers/enablers to the Capability, Opportunity, Motivation-Behaviour (COM-B) model. 2) Specifying behaviour change techniques (BCTs) in the existing DAFNE intervention using the Behaviour Change Techniques Taxonomy (BCTTv1). 3) Identifying additional BCTs to target the barriers/enablers using the BCW and BCTTv1. 4) Parallel stakeholder consultation to generate recommendations for intervention revision. Revised materials were co-designed by stakeholders (diabetologists, psychologists, specialist nurses and dietitians). RESULTS: Thirty-four barriers and five enablers to sustaining self-management post-DAFNE, were identified. The existing DAFNE intervention contained 24 BCTs, which partially addressed the enablers. Twenty-seven BCTs were added, including 'Habit formation', 'Credible source' and 'Conserving mental resources'. Fifteen stakeholder-agreed recommendations for content and delivery were incorporated into the final DAFNEplus intervention, comprising three co-designed components: (1) face-to-face group learning course, (2) individual structured follow-up sessions, (3) technological support, including blood glucose data management. CONCLUSIONS: This method provided a systematic approach to specifying and revising a behaviour change intervention incorporating stakeholder input. The revised DAFNEplus intervention aims to support the maintenance of behavioural changes by targeting barriers and enablers to sustaining self-management behaviours.
