An examination of the validity and reliability of the Caregiver Reaction Assessment Scale among Japanese family caregivers for older members


  • Ogura, Seiritsu


Objectives: Recent studies suggest the need to adjust the construct of the Caregiver Reaction Assessment Scale among the family caregivers according to different social norms and differential public services. The aim of this study is to examine the reliability of the original five-subscale CRA and to evaluate the four-subscale CRA proposed by Malhotra, Chan, Malhotra, and Ostbye (2012) among the Japanese family caregivers of old people. Method: I conducted confirmatory factor analysis of the original Given’s Caregiver Reaction Assessment scale among Japanese family caregivers for older persons and found its fit to be less than satisfactory. I then conducted exploratory factor analysis and modified CRA scale for a better fit. Results: The second confirmatory factor analysis of a modified four-factor CRA model, similar to the one developed by Manhotra et al., (2012), showed an acceptable fit. Furthermore, I checked group invariance between the two important groups of family caregivers in Japan-married women caring for parents-in-law and women caring for own parents-and confirmed configural and metric invariance of the modified (18-item four-factor) scale. Conclusion: Thus I believe my 18-item four-factor CRA is a good empirical instrument for evaluating both positive and negative effects of informal caregiving in Japan, and possibly in some other countries in Asia.
