The theory of planned behaviour and health behaviours
Bojan BilićThe paper critically analyses the capacity of the Theory of Planned Behaviour (TPB) to predict health behaviours. However, rather than focusing on specific health behaviours, the paper employs them as a framework for exploring the underlying methodological and theoretical issues that can interfere with both the reliability and the validity of the findings based on the TPB. It is argued that although the TPB can be regarded as an effective and parsimonious model for predicting health behaviours, there are serious conceptual problems that call for further research. Also, the final section of the paper outlines general difficulties in explaining human behaviour that will probably cause the TPB to be incorporated into a larger integrative model of human action.
