The Differences Between The Theory Of Planned Behavior (TBP) And The Trans Theoretical Model (TTM)’s Predictive Power Of Physical Activity

This study is to explore and discover the differences between theory of planned behavior(TPB) and Trans theoretical Model (TTM) to predict the behavior of an individual’s exercisebehavior.This research method is questionnaire survey. The measurement tools of this studyinclude these scales such as TPB scale, the scale of exercise activity’s level, the questionnaireof college students’physical activity which include the subscales of college students’stages ofchange in physical activity, the subscales of college students’ process of change in physicalactivity, the subscales of college students’ self-efficacy in physical activity and the subscalesof college students’decisional balance in physical activity.This study selected college students as subjects in Wuhan. We extract327non-sportsprofessional sports college students in Wuhan University, Central China normal universityand Wuhan institute of physical education. This study used statistical software SPSS17.0,AMOS6.0to sort and analyze the data.Results:(1) The attitude, subjective norms and behavior control of the individual candirectly predict the behavioral intention of the individual; the behavioral intention ofindividual can predict behavior directly; the attitude of the individual can not only predict thebehavior of the individual directly, but also can predict the behavior of the individualdirectly; the perceived behavior control of individual can predict the behavior of theindividual only through the behavioral intention of individual indirectly;(2) self-efficacy canpredict the Stage of Change directly, and can also predict the Stage of Change through theintermediary role of the Process of Change indirectly; the Decisional Balance can predict theProcess of Change directly; the Process of Change can predict the Stage of Change directly.(3)The model of TPB and TTM both reached the standard of a good model. But the model ofTPB is more simple than the model of TTM. However, the model of TTM still cannot berefused.
