The 'scientific' approach for the physical activity behaviour change

Interventions promoting various health enhancing behaviours such as physical activity and exercise have tended to lack the rigorous use of theory in both their design and implementation. The purpose of this review paper is to outline the stages involved in the development of a theory-based intervention. The paper highlights how the field has evolved to meet its ultimate goal; a solid scientific base. Steps including theory use, intervention techniques and technique taxonomies are outlined. The paper also addresses various considerations that have to be taken into account for valid interventions to be achieved.
