Abstract

<p>  The purpose of this study was to create a modified version of the Japanese Gerotranscendence Scale (Masui et al., 2010), and to determine the validity and reliability of the Japanese Gerotranscendence Scale Revised: JGS-R). JGS-R consists of eight factors based on the original items of JGS. A questionnaire survey was administered to 1,973 community-dwelling older adults in Japan using the JGS-R. After excluding missing values, we analyzed the data (n=1831; 52.3% women; aged 69-81) utilizing a confirmatory factor analysis. The results showed that with the hypothesized eight-factor structure, the model of the 27 items, after deletion of items with low factor loadings, demonstrated a high goodness of fit (GFI=.95 AGFI=.93 RMSEA=.044). Furthermore, we found the same factor structures as the original scale. We also collected data (n=344, 50.0% women; aged 49-71) via an online survey tool to examine the test-retest reliability of JGS-R. The test-retest reliability of the eight subordinate factors of JGS-R with a one-month interval was adequate at r= .55〜.83 but internal consistency of a few of the 34subordinate factors of JGS-R were low. It is concluded that JGS-R has validity and reliability at a certain level, but that there should be further improvement for items of subordinate scales.</p>
