Functional disability in Alzheimer disease: a validation study of the Turkish version of the disability assessment for dementia scale.
This study aimed to determine the reliability and validity of the Turkish version of Disability Assessment for Dementia (DAD) scale in the Turkish elderly population with Alzheimer disease (AD). The DAD scale was administered to the primary caregivers of 157 patients (age 77.7 ± 6.8 years) with AD. The Turkish version of the DAD scale showed high internal consistency (Cronbach α = .942), excellent test-retest, and interrater reliability (intraclass correlation coefficient [ICC] = 0.996 and ICC = 0.994, respectively). ⋯ The DAD total score was affected mostly by GDS, MMSE, and duration of the disease. Turkish version of the DAD scale was found to be a reliable and valid instrument to assess functional disability in Turkish elderly patients with AD. This scale assists caregivers and physicians to decide for proper interventions.
