Assessing cross-cultural equivalence through confirmatory factor analysis

This article presents a study in which Picot's caregiver rewards scale (PCRS), originally developed in English, was cross-culturally validated with 137 Chinese adult children family caregivers in the United States using confirmatory factor analysis. A one-factor structure of the 2 1 item revised Chinese PCRS was supported as indicated by goodness-of-fit index = .94, adjusted goodness-of-fit index = .93, standardized root mean square residual = .09, and chi-square to df ratio = 2.7. Chi-square for this model was (x(2) [189, n = 137] = 514, p < . 05). The standardized alpha was .90. All factor loadings were significant (p < .00) and above .30. Construct validity was supported by significant associations with caregivers' filial beliefs (r = .32, p < .01) and caregivers' filial affection toward parents (r = .23, p < .05). Results suggest that the Chinese PCRS is a summative measure of perceived caregiver rewards with potential for evaluating interventions to reduce perceived burden among adult children family caregivers.
