Purpose: The aim of this study was to develop a physical activity self-management agency scale that includes cognitive selfmanagement skills, and to examine the usefulness of the scale.
Method: The subjects were 193 students at University A. Scale development involved several phases, including item development, reliability testing, construct validity testing, and criterion-related validity testing. Furthermore, we examined the usefulness of the scale based on the relevancy of universal self-management agency and physical activity self-management agency.
Results: Confirmatory factor analysis was conducted to assess the extent to which the physical activity self-management agency scale structure fit the present data. The fit indices were approximately satisfactory (GFI = .955, AGFI = .926, RMSEA = .038). The scale comprises four factors with 11 items. Cronbach's alpha for the total scale score was .865. A significant difference in the scale score was observed with the continuance of exercise. It was also shown that physical activity self-management agency had a greater effect on continuing to exercise than universal self-management agency (β = .319, p < .01).
Conclusion: We developed a physical activity self-management agency scale and confirmed its construct validity, validity by external standards, and reliability. The usefulness of the scale was suggested.
