Abstract:
The paper critically analyses the capacity of the Theory of Planned Behaviour(TPB) to predict health behaviours. However, rather than focusing on specific healthbehaviours, the paper employs them as a framework for exploring the underlyingmethodological and theoretical issues that can interfere with both the reliability and thevalidity of the findings based on the TPB. It is argued that although the TPB can be regardedas an effective and parsimonious model for predicting health behaviours, there are seriousconceptual problems that call for further research. Also, the final section of the paperoutlines general difficulties in explaining human behaviour that will probably cause the TPBto be incorporated into a larger integrative model of human action.
