Correlation of Mini-Mental-State-Examination (MMSE), Syndrom-Kurztest (SKT) and Clock test (CT) scores in patients with cognitive impairment assessed by means of multiple regression and response surface analysis

Testing Older Adults for Signs of Age-Related Cognitive Decline: Clock Drawing Test vs.Mini-Mental State Examination

“…Scores lower than 25 indicate cognitive impairment. Its test-retest reliability and the inter-rater reliability are 0.89 and 0.82, respectively (Koch, Gürtler, & Szecsey, 2005). The psychometric properties of MMSE evaluated in Iran, represent the reliability and validity of MMSE as 0.78; and at the cut point of 21, it showed 90% sensitivity and 84% specificity (Foroughan, Jafari, Shirin Bayan, Ghaem Magham Faraahani, & Rahgozar, 2008).…”

“…Test-retest correlation using these categories was 0.89 and inter-rater correlation achieved 0.81. Its specificity and sensitivity appear to be slightly lower compared to the MMSE (Koch et al, 2005). The psychometric properties of CDT were evaluated in Iran, and would result in the test-retest reliability of 0.554 and ICC for inter-rater reliability was 0.96 (Sadeghipour Roodsari et al, 2013).…”

Prevalence and Persistence of Mild Cognitive Impairment among Elderly Patients in General Hospitals

“…In the follow-up after discharge from the hospital, a battery of tests was used which consisted of the syndrome short test (Syndrom-Kurztest, SKT) [29,30] , the MMSE, a verbal fl uency test (the number of animals named within 60 s) and a clock drawing test in the version of Manos and Wu [31] .…”

The DONPAD-study — Treatment of dementia in patients with Parkinson’s disease with donepezil

“…There were standardised visits via phone with the patients respectively their caregivers one week after I and II in order to check compliance of the patients, onset of side effects, change of concomitant medication and tolerability of the drug. The Clinical Global Impression Scale of severity respectively improvement (CGI), MMSE (Koch et al, 2005), Unified Parkinson's Disease Rating Scale (UPDRS) (Goetz et al, 2003) and Nurses Observation scale for geriatric patients, Version II (NOS) (Wahle et al, 1996) were performed at visits I, II, III, the Short Syndrome Test (SKT) (Overall and Schaltenbrand, 1992) only at visits I and III. Investigators were trained for diagnostic and rating procedures under standardized conditions.…”
