Abstract
Methods. We analyzed new cognitive screening method concurrent validity by comparing it in two groups formed on the basis of a comprehensive neuropsychological examination for 77 stroke patients. We identified the best balance of sensitivity and specificity by using receiver operating characteristic curve analysis and investigated the impact of the sociodemographic variables to the screening method total score variation.
Results. We found a significant correlation between the method’s total score and performance in neuropsychological examination. The cognitive method’s internal consistency was strong; Cronbach’s alpha for all items was .818. The best balance of sensitivity (88%) and specificity (50%) was found at a total score cut point of 138. Subjects’ age and length of education were each responsible for 10% of total score variation.
Conclusions. This study shows promising results for this new cognitive screening tool’s ability to identify poststroke cognitive decline and patients’ need for further detailed neuropsychological examination.
