In the 2nd year of ths project, the study investigates the physical activity distribution of Korea adults, examines the differences in the TTM constructs by the stage of physical activity, and identify the relationship between physical activity and the TTM constructs. A total of 799 adults (male: 326, female: 473, Mage = 46.8 years) randomly recruited from S district in Seoul, Korea. Four Korean-version questionnaires were used to identify the stages of physical activity and its related psychological variables: stage of physical activity change scale, decision balance scale for physical activity, exercise self-efficacy scale, and processes of change scale for physical activity. Results indicated that a significant difference among male and female adults for physical activity stage distribution emerged (2 = 67.2, df = 4, p<.001). Data were analyzed by frequency analysis, 2 test, MANOVA, and regression analysis. Self-efficacy, pros, cons, cognitive processes of change, and behavioral processes of change differentiated across the stages of physical activity. Furthermore, the findings revealed that adults’ physical activity was significantly correlated with the TTM constructs, and that the TTM constructs had a statistically significant impact on the physical activity. The current study provides starting points for interventions aimed at increasing physical activity levels based on the TTM.
In the 3rd year of this project, the study examined the effect of a weight control intervention on BMI, physical activity levels, and psychological variables toward physical activity. Thirty-three middle-aged obese women participated in the 16-week weight control intervention. Results indicated that the participants’ BMI significantly decreased and physical activity levels significantly increased over the intervention. Moreover, Exercise self-efficacy and perceived benefits toward physical activity significantly increased, but perceived barriers of physical activity gradually decreased over the intervention. The study suggests that it is important to consider not only physical activity itself, but also the various psychological variables when planning and implementing the weight control program.
