      (K-IADL): Clinical Usefulness for Various Neurodegenerative Diseases.

AB  - BACKGROUND AND PURPOSE: Evaluating instrumental activities of daily living (IADL) 
      is an important part of procedure to diagnose dementia. The Korean-Instrumental 
      Activities of Daily Living (K-IADL) has been used extensively in Korea. However, 
      its cut-off score has not been reformulated since 2002. The purpose of this study 
      was to yield a new optimal cut-off score for the K-IADL and confirm the validity 
      of this new cut-off score with various dementia groups. METHODS: We 
      retrospectively collected a total of 2,347 patients' K-IADL data from 6 general 
      hospitals in Korea. These patients had mild cognitive impairment (MCI) or 
      dementia with various etiologies for cognitive impairment. We also recruited a 
      normal control group (n=254) from the community. Korean-Mini Mental State 
      Examination, Short version of the Geriatric Depression Scale, Clinical Dementia 
      Rating, and Global Deterioration Scale were administered to all participants. 
      Caregivers completed K-IADL and Barthel Index. RESULTS: K-IADL scores were 
      significantly different among dementia subgroups, but not significantly different 
      among MCI subgroups. Based on internal consistency, correlations with other 
      scales, and factor analysis, K-IADL showed excellent reliability and validity. 
      The new optimal cut-off score to diagnose dementia was 0.40, which gave a 
      sensitivity of 0.901 and a specificity of 0.916. Positive predictive value for 
      dementia using the new cut-off score was 94.2% for Alzheimer's disease, 100% for 
      vascular dementia, and 84% for Parkinson's disease. CONCLUSIONS: Our results 
      illustrate that the new K-IADL cut-off score of 0.40 is reliable and valid for 
      screening impairments of daily functioning resulting from various etiologies.
