Özet
This study adapted the Care Challenge Scale (CCS) into Turkish and evaluated its validity and reliability for Turkish caregivers of Alzheimer’s patients. The CCS was translated and validated through exploratory and confirmatory factor analyses with a sample of 100 caregivers. The Cronbach alpha coefficient was 0.915 overall, and 0.835 and 0.905 for the subscales. Test-retest reliability was r=0.700. The content validity index (CVI) was 0.80. Exploratory factor analysis explained 68.446% of variance across two subscales (lack of social-financial support, effective roleplay challenge). Confirmatory factor analysis supported the two-dimensional structure (χ²/df = 1.676, RMSEA=0.083). The CCS was found to be a valid and reliable instrument for assessing care challenge levels among caregivers of Alzheimer’s patients.
