Summary
This chapter presents the Theory of Planned Behavior as a structured framework for designing and evaluating behaviour change interventions. The authors outline a sequential methodology encompassing belief research, questionnaire construction and validation, structural model confirmation, and intervention testing and evaluation. The framework has demonstrated predictive validity in behaviour modification research, though the authors note that future work is needed to identify additional effective strategies for changing TPB determinants.
Regional applicability
The Theory of Planned Behavior is a general psychological framework applicable across geographies and contexts. Its utility for designing behaviour change interventions (including those relevant to food, agriculture, and health behaviours) is internationally transferable, though specific application to UK policy or practice would depend on context-specific belief research and validation.
Key measures
Behavioral, normative, and control beliefs; attitudes; subjective norms; perceived behavioral control; behavioral intention; volitional control; behaviour change outcomes
