ABSTRACT
Designing interventions to change behaviour and improve implementation first requires understanding the influences on current and desired behaviours in the context in which they occur. This can be facilitated through the application of evidence-based theories and frameworks from behavioural science. The Theoretical Domains Framework (TDF) has been applied to explore barriers and enablers to implementing change in behaviours from antibiotic prescribing to vaccination uptake. The TDF is linked to the Behaviour Change Wheel and Behaviour Change Technique Taxonomy, which specify different types of behaviour change strategies. This facilitates decision-making during intervention design and supports more systematic, transparent, and theory-based development of implementation interventions. However, the TDF does not specify relationships between construct domains, and some argue that the TDF focuses predominantly on individual rather than organizational behaviour change. This has led the TDF to often be used alongside other implementation frameworks, such as the Consolidated Framework for Implementation Research (CFIR).
