[Spanish adaptation of the Alzheimer's disease assessment scale (ADAS)]

The Alzheimer's Disease Assessment Scale, was designed specifically to evaluate the severity of cognitive and noncognitive behavioral dysfunctions characteristic of persons with Alzheimer's disease. Twenty-one items with significant intraclass correlation coefficients for interrater reliability (0.975 for cognitive subscale, 0.933 for noncognitive subscale and 0.973 for total score), significant Spearman correlation coefficients for test-reliability (0.901 for cognitive subscale 0.574 for noncognitive subscale and 0.824 for total score) and significant correlation coefficients for concurrent validity (0.872 for subscale cognitive, 0,584 for noncognitive subscale), constitute the scale.
