摘要: Objective: The Montreal Cognitive Assessment (MoCA) is a cognitive screening instrument growing in popularity, but few studies have conducted psychometric item analyses or attempted to develop abbreviated forms. We sought derive and validate short-form MoCA (SF-MoCA) compare its classification accuracy the standard Mini-Mental State Examination (MMSE) mild impairment (MCI), Alzheimer disease (AD), normal aging. Methods: 408 subjects (MCI n = 169, AD n = 87, n = 152) were randomly divided into derivation validation samples. Item analysis sample identified most sensitive items. Receiver Operating Characteristic (ROC) used cut-off scores evaluate of SF-MoCA, MoCA, MMSE. Net Reclassification Improvement (NRI) comparison ROC curves three measures. Results: Serial subtraction (Cramer’s V = .408), ...
