日本版老年的超越質問紙の改訂版(Japanese Gerotranscendence Scale Revised;JGS-R)を作成し,その妥当性と信頼性を検討した.JGS-Rを地域在住高齢者1,973人に実施し,欠損のないデータ(n=1,831,女性52.3%,年齢範囲69~81歳)を用いて確認的因子分析を行った.その結果,最終的なモデルの適合度(GFI=.95;AGFI=.93;RMSEA=.044)は十分に高く,JGSと同様の因子構造が確認された.再検査信頼性は,インターネット調査モニター(n=344,女性50%,年齢範囲49~79歳)のデータを用いて検討した.調査間隔1か月のJGS-Rの8つの下位尺度の再検査信頼性はr=.55~.83であった.一方,内的一貫性の低い下位因子もあった.これらの結果から,JGS-Rには一定の妥当性および信頼性が確認されたが,尺度のさらなる検討の必要性も示唆された.
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 34 subordinate 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.
