Development and validation of the Japanese version of the Personal Attitude Stability Scale (PASS-J)

Abstract

The purpose of this study was to develop the Japanese version of the Personal Attitude Stability Scale (PASS-J) and examine its reliability and validity. Personal attitude stability refers to individual differences in people’s perceived attitude stability that predict the actual stability of their attitudes over time. Three web surveys were conducted to examine the reliability and validity of the scale. The results of confirmatory factor analysis of data from the three surveys showed that the PASS-J had the same factor structure as the original scale. Additionally, survey 1 and 2 established test-retest reliability over a two-week period. Furthermore, the results of the multilevel modeling indicated that in the case of people with high scores on the PASS-J, their Time 1 attitudes were more predictive of their Time 2 attitudes. This confirmed the scale’s predictive validity. Lastly, in survey 3, the correlation analyses between the PASS-J and existing scales confirmed its convergent validity. Thus, the PASS-J was confirmed as a useful measure of personal attitude stability.
