Zammitti Taylor Maynard Kunal Mankodiya Nicholas Constant Charles Denby Alyssa N. De Vito George D. Papandonatos Brian R. Ott Geoffrey Tremont Alzheimer's & Dementia: Diagnosis, Assessment & Disease Monitoring Abstract INTRODUCTION This study evaluated the reliability and validity of the Rhode Island Mobile Cognitive Assessment Tool (RIMCAT), a proctored digital cognitive screening test. METHODS One hundred older adult participants (healthy controls [HC] n = 50; cognitively impaired [CI], n = 50) completed the RIMCAT. RESULTS Test–retest reliability across 4 weeks was excellent. Internal consistency was high. RIMCAT total scores were significantly correlated with the Mini‐Mental State Examination and the Mattis Dementia Rating Scale. RIMCAT component scores were significantly correlated with corresponding in‐office neuropsychological measures. Logistic regression analysis of RIMCAT total scores correctly classified 77.9% of individuals as cognitively impaired or cognitively healthy. Receiver operating characteristic analysis revealed an optimal sensitivity of 84.8% and specificity of 79.6%. A second model, including total reaction time, correctly classified 83.2% of cases and resulted in sensitivity and specificity of 84.8% and 83.7%, respectively. DISCUSSION Results supported RIMCAT as an effective digital tool for cognitive screening of older adults in supervised settings. 10.1002/dad2.70113 http://creativecommons.org/licenses/by-nc-nd/4.0/ |
