Abstract
- The purpose of this study is to examine the reliability and validity of the ADRQL instrument among older adults with cognitive impairment in mainland China. Three hundred older adults with cognitive impairment and their primary family caregivers from Wuhan participated in structured interviews. Cronbach's α and Kuder–Richardson Formula 20 were used to examine internal consistency reliability. Confirmatory factor analysis, Heterotrait-Monotrait ratios, and ordinary least square regression were used to assess the factorial validity, discriminant validity, and criterion validity. The ADRQL had acceptable reliability and validity, which can be used to assess overall quality of life for this population. [ABSTRACT FROM AUTHOR]
