Behaviour Change Wheel (BCW)

The Behaviour Change Wheel (BCW) is a systematic, evidence-based framework for designing behavior change interventions. Developed by Michie et al. (2011) and built on the COM-B model (Capability, Opportunity, Motivation→Behavior), the BCW guides practitioners through a structured process: diagnose behavior change barriers (using the Theoretical Domains Framework), identify relevant intervention functions (education, persuasion, incentivization, coercion, training, restriction, environmental restructuring, modelling, enablement), and design specific behavior change techniques matched to policy categories. It has become the international standard for systematically designing behavior change interventions in healthcare, public health, and other domains.
