A new rating scale for Alzheimer's disease
Wilma G. Rosen, Richard C. Mohs, Kenneth L. Davis. American Journal of Psychiatry, 1984-11-01
Topic: Amyloid, tau and blood-test diagnosis
A new rating instrument, 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. Item descriptions, administration procedures, and scoring are outlined. Twenty-seven subjects with Alzheimer's disease and 28 normal elderly subjects were rated on 40 items. Twenty-one items with significant intraclass correlation coefficients for interrater reliability (range, .650-.989) and significant Spearman rank-order correlation coefficients for test-retest reliability (range, .514-1) constitute the final scale. Subjects with Alzheimer's disease had significantly more cognitive and noncognitive dysfunction than the normal elderly subjects.
Key findings
- Twenty-one items with significant intraclass correlation coefficients for interrater reliability (range, .650-.989) and significant Spearman rank-order correlation coefficients for test-retest reliability (range, .514-1) constitute the final scale.
- Subjects with Alzheimer's disease had significantly more cognitive and noncognitive dysfunction than the normal elderly subjects.
Why it matters
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. In testing with 27 Alzheimer's disease subjects and 28 normal elderly subjects, those with Alzheimer's disease had significantly more cognitive and noncognitive dysfunction than the normal elderly subjects.
