A Validation Study of the Korean Version of the CASP-16

Abstract

The aim of this study is to validate and test the psychometric properties of the Korean version of the Quality of Life in Old Age (CASP-19) developed by Hyde, Wiggins, Higgs, and Blane (2003). A total of 345 respondents aged 55 years and older were selected by an online survey and the sample was divided in half at random to perform exploratory and confirmatory factor analysis. Results from the exploratory factor analysis revealed that the Korean version of the CASP-16 (K-CASP-16) were divided into four domains (‘control’, ‘autonomy’, ‘pleasure’ and ‘self-relization’), which was consistent with the original version. In the confirmatory factor analysis, a second-order four domains model showed a good overall fit of K-CASP-16. The K-CASP-16 correlated with Satisfaction With Life Scale (r=.735) and showed an adequate internal consistency (α=.882). The results of this current study indicate that the K-CASP-16 is a reliable and valid scale. Finally, the significance, clinical implications, limitations of this study were discussed in relation with future studies.
