SKT short cognitive performance test and activities of daily living in Dementia

Using data from two randomized, placebo-controlled trials involving 806 outpatients, we performed linear regression analyses to evaluate how cognitive abilities in patients with dementia assessed by the SKT (Syndrom-Kurztest-Short Cognitive Performance Test) correlate with activities of daily living rated by means of the Activities of Daily Living International Scale (ADL-IS). There were significant correlations between SKT total score and ADL-IS total mean score at baseline (r = 0.52, p .001) as well as between change in SKT total score and change in ADL-IS total mean score during the 24-week treatment period (r = 0.48, p .001). Significant correlations with ADL-IS total mean scores were also found for both memory and attention/concentration subscores of the SKT.
