Scott J. Leischow, PhD, Tobacco Control Research Branch, National Cancer Institute, Executive Plaza North, Room 4038, 6130 Executive Boulevard, MSC 7337, Bethesda, MD 20892-7337, 301-496-8584, sleischow@azcc.arizona.edu
Tobacco researchers operate in a paradigm in which processes are studied in isolation, and factors external to a process are treated as unrelated or unimportant. Further, hypotheses often specify unidirectional relationships under the presumption that causes are not influenced by effects. Systems thinking evolved in response to this oversimplified view of the world. It involves moving away from the analysis of isolated events and their causes toward focusing on the relationships that exist within a system as a whole. The objective of this symposium is to provide a primer on systems thinking and its application to the study and evaluation of tobacco control systems. First, Dr. Levy will discuss the role of dynamic simulation models in evaluating tobacco control policies, smoking rates, and health outcomes. Next, using data from the Health and Retirement Study, Dr. Shaw will demonstrate how econometric methods may be used to generate and test models of complex systems. Dr. Luke will then discuss the use of network analysis as a tool for describing the complexity of tobacco control systems. Dr. Mendez will present the results of a dynamic simulation conducted to examine the relative impact of different types of smoking control policies on mortality and medical costs. Finally, Dr. Valente will discuss a study of a network approach for selecting peer leaders to assist in implementing school-based tobacco prevention programs. Dr. Leischow will moderate questions from the audience and discuss how federal agencies, including the National Cancer Institute, are currently promoting systems thinking in tobacco research.
Learning Objectives: At the conclusion of this session, participants will be able to
