| Summary: | 博士 === 國立臺灣師範大學 === 衛生教育學系 === 99 === The main purpose of this study was to analyze the effects of a physical activity education program on the stages of change, physical activity, knowledge of physical activity, perceived barriers and perceived benefits, self-efficacy, processes of change, and attitudes toward physical activity among the Taipei Municipal junior high school students.
This study adopted the quasi-experiment design and the samples filled out three wave questionnaire, including pre-test, post-test, and post post-test (3 month later). Two Taipei Municipal junior high schools were purposively selected as the study schools. The total effective number of the experimental group was 113, with the control group being 128. The experimental group participated eight-week, eight sessions physical activity education program, while the control group didn’t take any course.
The study used the processes of change and stages of change to design the physical activity education intervention. The teaching strategy included narrating, group discussion, value clarification, individual sharing, role play, video, exercise, worksheet and group contest. Besides, the experimental group received physical activity teaching materials as well.
GEE analysis was used to estimate the effects of physical activity education intervention. This study found that the intervention had a positive effect of physical activity behavior among the junior high school students. The main findings were as follows : (1)After interactions with groups over time, the two groups showed statistically significant difference (p<.05) on post-test on physical activity, knowledge of physical activity, perceived barriers of physical activity, processes of change, and attitudes toward physical activity. (2)After interactions with groups over time, the two groups showed statistically significant difference (p< .05) on post post-test of stages of change, physical activity, knowledge of physical activity, perceived barriers of physical activity, self-efficacy, and processes of change. (3)the two groups didn’t show statistically significant difference (p＞.05) on post-test and post post-test on perceived benefits of physical activity. Totally, the experimental group was significantly better than control group on variables mentioned above.
According to the study findings, it is suggested that the Transtheoretical Model could be used to design the physical activity education program for the junior high school students. Schools should provide proper physical activity environment and get parents and teachers involved in physical activity program.
