Abstract
Background: The Family Crisis Oriented Personal Evaluation Scales (F-COPES) is a widely used instrument to evaluate family coping behaviours. However, no Chinese version of this scale have been developed and validated in China. This study aimed to develop a Chinese version of the F-COPES and evaluate its psychometric properties in the families of patients with dementia who have heavy stress and care burdens.Methods: A cross-sectional study in the specialist memory and geriatric psychiatric clinics of four hospitals in Beijing, China. The English version of the F-COPES was translated into Chinese according to the standard translation guideline. An expert panel was invited to evaluate the content validity index of the Chinese version of this scale. This study included 215 families of patients with dementia. The item homogeneity analysis was conducted by using corrected item-total correlation, corrected item-subscale correlation, and changes of Cronbach’s alpha coefficient of subscales after deleting each item. The factor structure was analysed by using a confirmatory factor analysis. The convergent validity was tested by correlating the F-COPES to the Multidimensional Scale of Perceived Social Support (MSPSS). The internal consistency was assessed by using Cronbach's alpha coefficients of the whole scale and subscales.Results: The content validity index of the Chinese version of the F-COPES was 0.98, with that of each item ranging from 0.83 to 1.00. The result of item homogeneity analysis was satisfactory except for the items in the subscale of passive appraisal. The confirmatory factor analysis identified six subscales; namely, acquiring relatives’ support, acquiring friends’ support, acquiring neighbours’ or others’ support, reframing, seeking spiritual support, and passive appraisal, with acceptable model fit indices (χ2/df = 1.65, CFI = 0.91, GFI = 0.85, TLI = 0.90, PGFI = 0.69, RMSEA = 0.06). The convergent correlation between the F-COPES and the MSPSS was strong (r = 0.50, P < 0.01). The Cronbach's alpha coefficients of the whole scale was 0.86.Conclusion: The Chinese version of the F-COPES showed satisfactory psychometric properties. It may serve as a useful scale for assessing the coping behaviours in families of patients with dementia in China.
