Korean version of the Revised Caregiving Appraisal Scale: a translation and validation study

Abstract

AIM: This paper is a report of a study to examine the reliability and validity of a Korean version of the Revised Caregiving Appraisal Scale with Korean caregivers of older stroke survivors. BACKGROUND: The Revised Caregiving Appraisal Scale was developed in the United States of America for an American English-speaking population to measure primary caregivers' appraisals of potential stressors and the efficacy of their coping efforts related to caregiving experiences. METHODS: Using the back-translation method, the instrument was translated into Korean. The Korean version of the Revised Caregiving Appraisal Scale was self-administered by 147 primary family caregivers recruited from three outpatient clinics and two home health agencies in Korea. The study was conducted in 2005. RESULTS: In this sample, Cronbach's alpha for the total scale was 0.86. Reliability coefficients for each of the five subscales ranged from 0.40 to 0.85. Two subscales, burden and satisfaction, showed good reliability; one subscale, impact, showed marginally acceptable reliability; two subscales, mastery and demand, had low reliability. Principal components factor analysis of the Korean version of the Revised Caregiving Appraisal Scale yielded six factors. Except for the mastery domain, which was divided into two factors, the other factors were similar to those in the original scale. CONCLUSION: The Korean version of the Revised Caregiving Appraisal Scale had adequate reliability and validity in a sample of Korean caregivers of stroke survivors. It can be used to assess the impact of caregiving and interventions on Korean caregiver attitudes. Further studies are needed with different categories of caregiver.
