The Farsi version of Caregiver Preparedness Scale in Iranian family caregivers of the older adults undergoing hemodialysis: a psychometric study

Abstract

Abstract Background Enhancing preparedness of family caregivers and support for caregiving is essential for the mutual benefit of both caregivers and the well-being of those under their care. This study aimed to translate and evaluate psychometric properties of the Caregiver Preparedness Scale among family caregivers of older adults undergoing hemodialysis. Methods In this methodological study, 400 family caregivers of older adult patients undergoing hemodialysis enrolled to the study via convenience sampling method. The study was conducted in two stages: translation and psychometric evaluation. At first, the translation of the scale was done using Beaton et al. method. In the psychometric evaluation stage, quantitative face validity, content validity, item analysis and construct validity of the scale were evaluated. The internal consistency of the scale was assessed through the calculation of Cronbach’s alpha, McDonald’s omega, and average inter-item correlation coefficients. Results All items had an impact score greater than 1.5. The content validity ratio and the kappa coefficient for all items were above 0.75. In the item analysis, item 2, which had a correlation with the total score of less than 0.3, was removed. Following exploratory factor analysis, only one factor composed of all items (7 items) was extracted, explaining 75.7% of the total variance. This model had acceptable fit indices in confirmatory factor analysis. Cronbach’s alpha and omega of 0.95 and an average inter-item correlation of 0.75 were obtained. Conclusions The study results demonstrated that the Caregiver Preparedness Scale exhibits appropriate psychometric properties. Geriatric nurses can utilize this Scale for assessment of caregivers. This assessment can aid in decision-making regarding educational programs aimed at enhancing family caregiver preparedness.
