A new theoretical framework for modelling and analysing complex tobacco control systems

This paper presents a new theoretical framework for modelling and analysing complex tobacco control systems. First, we propose an interaction model that identifies the key components of a tobacco control system, and how these components interact with each other to affect the outcomes of tobacco control policy planning and development. Second, we provide a conceptual model that articulates a cycle of tobacco control policy planning/making, enactment, monitoring and refinement. Finally, we outline the major challenges of applying this approach to real life. This framework provides a useful way of studying the relationship between science, policy and the outcomes of policy for tobacco control. It has potential to become a good framework for other complex social issues, such as nutrition and its links to various issues including cancer, cardio-vascular disease and ageing.
