The Saint Louis University Mental Status Examination Is Better than the Mini-Mental State Examination to Determine the Cognitive Impairment in Turkish Elderly People

Abstract

IntroductionPresence of detailed screening instruments to detect cognitive impairment in the older adults' culture and language is very essential. The Saint Louis University Mental Status Examination (SLUMS) is one of cognitive screening scales used. The aim of the study was to establish the validity and reliability of the Turkish version of SLUMS (SLUMS-T). MethodsTwo hundred seventy-four participants aged 60 years and older admitted to our geriatric clinic were screened for cognitive impairment using SLUMS-T and Mini-Mental State Examination. Internal consistency was analyzed with Cronbach α test. Area under curves of receiver operating characteristic analyses were used to test the predictive accuracy of the SLUMS-T for detecting amnestic mild cognitive impairment (aMCI) and Alzheimer disease (AD) to set an appropriate cut-off point. ResultsThe SLUMS-T scores were positively correlated with the Mini-Mental State Examination scores of the patients with aMCI and patients with AD and controls (r = 0.687, P < .001; r = 0.880, P < .001; respectively). Internal consistency of the SLUMS-T was Cronbach α = 0.85. It was found that SLUMS-T with a cut-off point of 23 had a sensitivity of 66.6% and a specificity of 72.3% for the diagnosis of aMCI, and with a cut-off point of 20 had a sensitivity of 83.8% and a specificity of 87.3% for the diagnosis of AD. ConclusionsSLUMS-T was demonstrated to have sufficient validity and reliability to evaluate cognitive impairment including MCI among Turkish elderly people.
