AB  - BACKGROUND: Evaluating the activities of daily living (ADL) is an important 
      factor for diagnosing dementia. The Everyday Cognition (ECog) scale was developed 
      to measure ADL changes that were correlated with specific neuropsychological 
      impairments. A short form of the ECog (ECog-12) was also developed, consisting of 
      12 items, two from each of the six cognitive domains of the ECog. The Korean full 
      version of ECog (K-ECog) has recently been standardized, but the need for a 
      shortened version has been raised in clinical practice. The purpose of this study 
      was to develop a Korean version of ECog-12 (K-ECog-12) and to verify its 
      reliability and validity by comparing those to the full version of K-ECog. 
      METHODS: The participants were 267 cognitively normal older adults (CN), 183 
      patients with mild cognitive impairment (MCI), and 89 patients with dementia. The 
      Korean-Mini Mental State Examination (K-MMSE), Korean-Montreal Cognitive 
      Assessment (K-MoCA), and Short form of Geriatric Depression Scale (SGDS) were 
      administered to all participants. The K-ECog and Korean-Instrumental Activities 
      of Daily Living (K-IADL) were rated by the informants of patients. RESULTS: 
      K-ECog-12 was newly constructed by replacing one item for the visuospatial 
      function in the original ECog-12 with another one through an item response theory 
      analysis on Korean data. The internal consistencies (Cronbach's alpha) of K-ECog-12 
      and K-ECog were 0.95 and 0.99, respectively. The test-retest reliabilities 
      (Pearson's r) were 0.67 for K-ECog-12 and 0.73 for K-ECog. The K-ECog-12 was 
      significantly correlated with K-ECog as well as K-IADL, K-MMSE, and K-MoCA. The 
      K-ECog-12 scores differed significantly between the CN, MCI, and dementia groups, 
      as did the K-ECog scores. Receiver operating characteristic curve analyses showed 
      that K-ECog-12, like K-ECog, could differentiate MCI and dementia patients from 
      CN as well. CONCLUSION: The K-ECog-12 is as reliable and valid as the K-ECog in 
      assessing ADL. Therefore, K-ECog-12 can be used as an alternative to the K-ECog 
      in clinical and community settings in Korea.
