Aim: The purpose of this study is to further develop the newly-developed measure, The Scale of Social Activities among Community-dwelling Elderly People（SSAC）.
Method: The Subjects were 2,928 persons over 65 years old, randomly extracted from A City in Japan. First, a pool of items was developed by literature reviews and qualitative data from our previous studies. Second, the construct validity was determined by a confirmatory factor analysis（CFA）and the criterion-related validity was evaluated with the Philadelphia Geriatric Center Morale Scale（PGC）, and going-out frequency. And lastly, the internal consistency was calculated by Cronbach’s α of the SSAC.
Results: The number of responses was 906（valid response rate: 87.1 %）, of whom 53.5% were male and 46.5% were female. The mean age ±SD was 72.3 ± 5.9 years old. The CFA showed two main factors; Factor Ⅰ : ‘self-enlightenment activities’ and Factor Ⅱ : ‘community contributive activities’ with six items in the SSAC（GFI=0.992, AGFI=0.987, CFI=0.988, RMSEA=0.026）. The scores of the SSAC had a significant correlation with PGC and going-out frequency respectively. The Cronbach’s alpha coefficient of total items of the SSAC was 0.78.
Conclusion: It was concluded that the SSAC demonstrated adequate psychometric properties to measure social activities among community-dwelling elderly people.
