Abstract
The purpose of this study was to reveal the characteristics of sources of exercise self-efficacy in each stage of change for exercise among older adults. The subjects were 365 people aged 60 or above (166 males, 199 females, with a mean age of 74.21) who completed a set of measurements including sources of exercise self-efficacy, exercise self-efficacy, and stages of change for exercise. Results revealed that more than half of the subjects (52.6%) were in action or maintenance stage, and that the total scores of sources of exercise self-efficacy and the total exercise self-efficacy score increased gradually as the stage progressed. Moreover, the score of each sources of exercise self-efficacy had a similar tendency. Results of this study suggest a new effective strategy to increase the amount of exercise among older adults.
