Caregiver Difficulties Scale (CDS): Translation and Psychometric Evaluation Among Iranian Mothers of Cerebral Palsy Children

ABSTRACTThe aim of this study was to investigate of psychometric properties of the Caregiver Difficulties Scale (CDS) for Iranian caregivers of children with cerebral palsy (CP). After a forward-backward translation, the Persian version of CDS (P-CDS) was administered to 151 Iranian mothers of CP children. The confirmatory factor analysis (CFA) was applied to measure the factor structure of P-CDS. The reliability was evaluated by examining internal consistency and test-retest method over a 2-week period using Cronbach's alpha and the intraclass correlation coefficient (ICC), respectively. The construct validity was assessed by measuring the association between the scores of the P-CDS and Caregiver Burden Scale (CBS), World Health Organization Quality of Life (WHOQOL-BREF), the Beck Depression Index (BDI II), and the Fatigue Severity Scale (FSS). The fit indices showed that the original model of CDS was relatively adequate (χ2/df = 2.03, CFI = 0.90, TLI = 0.88 and RMSEA = 0.08). All domains of P-CDS met th...
