AB  - BACKGROUND: In the early diagnosis of dementia, an important factor is the 
      evaluation of activities of daily living. The Everyday Cognition (ECog) scale was 
      developed to measure functional changes that are the everyday correlates of 
      specific neuropsychological impairments. This study aimed to examine the validity 
      of the Korean version of Everyday Cognition (K-ECog). METHODS: The participants 
      were 268 cognitively normal older adults (NA), 151 amnestic mild cognitive 
      impairment (aMCI), and 77 dementia of the Alzheimer's type (DAT). The Korean-Mini 
      Mental State Examination (K-MMSE), Korean-Montreal Cognitive Assessment (K-MoCA), 
      and Short form of the Geriatric Depression Scale (SGDS) were administered to all 
      the participants. The K-ECog and Korean-Instrumental Activities of Daily Living 
      (K-IADL) were rated by their informants. RESULTS: Internal consistency 
      (Cronbach's alpha) of K-ECog global function was 0.93, and its test-retest 
      reliability (Pearson's r) was 0.73. K-ECog was significantly correlated with 
      K-IADL (0.66), K-MMSE (-0.38), and K-MoCA (-0.26). Confirmatory factor analysis 
      of K-ECog yielded seven factor model that the original ECog proposed. K-ECog 
      global score and six domain scores were significantly different across the NA, 
      aMCI, and DAT groups. Receiver operating characteristic curve analyses showed 
      that K-ECog effectively differentiated aMCI and DAT patients from NA, suggesting 
      that K-ECog is as sensitive for detecting functional impairments as K-IADL. The 
      proposed optimal cut-off score to differentiate aMCI from NA was 1.41. 
      CONCLUSION: K-ECog is proven reliable and valid for clinical use. K-ECog can be 
      used to distinguish very early stages of impaired ADL and cognitive impairment in 
      the community.
