This article reviewed the transtheoretical model which has been frequently applying to explain physical activity in exercise and health-related areas, and discussed a series of validation study of measurement tools, cross-sectional study, and intervention study which are divided as the characteristics of research methods applied in the previous studies Finally, the paper suggests several considerations when preparing transthereotical model based on the previous studies. Most studies have focused on White, middle-class, female populations, limiting the generalizability of their findings. valid and reliable measures exist for stage of change, decision balance, processes of change, and self-efficacy; however, more research is needed to refine these measures. When designing and implementing stage-matched physical activity interventions based on the transtheoretical model, researchers are encouraged to clearly define the term physical activity, choose valid and reliable staging scale, and employ all transtheoretical model constructs.
