The first objective of this study was to develop a Japanese version scale of the Stages of Exercise Behavior Change and Exercise Self-Efficacy. Data for study 1 were obtained from 282 walking event participants. The validity of criteria for the scale of Stages of Exercise Behavior Change and factorial validity and reliability for the scale of Exercise Self-Efficacy were examined. The results of study 1 were as follows : 1) The higher the Stages of Exercise Behavior Change, the higher the frequency and the more practice time for exercise. 2) It became clear as a result of a confirmatory factor analysis that GFI and AGFI of 1 factor model in Exercise Self-Efficacy were at an acceptable level (GFI.976 and AGFI.927). Moreover, the Cronbach α coefficient was. 806. The second objective of this study was to examine the application of two scales developed in Study 1 for older adults. Data for Study 2 were obtained from 226 visitors over 60 years of age to an interchangeable facility for older adults. The results of Study 2 were as follows : 1) There was the similar tendency as study 1 in two scales. 2) There was no linear relationship between the Stages of Exercise Behavior Change and Exercise Self-Efficacy, as indicated in the previous study
