概要	Normalization Process Theory (NPT) is a sociological framework developed by Carl May and colleagues to explain how new interventions become routinely embedded ('normalized') in organizational and clinical practice. Unlike efficiency-focused frameworks that measure adoption and fidelity, NPT explains the social processes through which interventions transition from external innovations to normal practice. NPT identifies four key mechanisms (Coherence, Cognitive Participation, Collective Action, Reflexive Monitoring) that collectively determine whether an intervention becomes 'the way we do things here' or remains a temporary project.	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.
