The purpose of this study is to examine a cross-validity and a reliability of a measurement of "SEKENTEI" for factor analysis of social welfare services. "SEKENTEI" is the level of a person's self-consciousness of others observing one's behavior and endeavoring to meet the perceived norms of behavior. Data used in this study were obtained from 3 types of the populations, the first one was elderly people who participate in educational services, the second one was person attending a class of home-helper, the third one was primary family caregiver. The "SEKENTEI" Index was examined on an immutability of the factor structure and a test-retest reliability. A factor analysis, coefficient Al fa and correlation coefficient was used in this analysis. The results were as follows : 1) On this study, there were 3 cases of the factor structure in the "SEKENTEI" Index. That was 3 factor structure, 4 factor structure and 5 factor structure (eigin value>1.0). 2) The "SEKENTEI" Index of This study was similar to previous studies on the character concerning factor loading of the 12 items. 3) The coefficient Al fa of the "SEKENTEI" Index were approving level (.71〜.77) on this study. 4) On test-retest reliability, the reliability coefficient of the "SEKENTEI" Index were not high level one. By these result, it was suggested that the "SEKENTEI" Index did not have a high level cross-validity and a high level a reliability. Based on these results, it appears that the "SEKENTEI" Index will be a sound measurement of "SEKENTEI", if it is partly revised.
