The sensitivity, specificity, positive and negative likelihood ratios, and positive and negative predictive values of MoCA are 87.18%, 74.03%, 3.35, 0.17, 63%, and 91.9%, respectively. The optimal cutoff value was ≤ 21, and Montreal Cognitive Assessment has an area under curve value of 0.89. The inter-rater reliability value was 0.96, and Cronbach’s alpha was 0.79. The mean age of the study participants was 69.87 ± 7.8. Results: The study had a 100% response rate. Statistically significance was declared at a p-value of < 0.05. Receiver operating curve analysis was performed, and inter-rater, internal consistency reliabilities, content, criterion and construct validities were determined. Data were analyzed using STATA v16 statistical software.

Purpose: This study was designed to assess the reliability and validity of the Montreal Cognitive Assessment (MoCA) tool to detect major neurocognitive disorders among older people in Ethiopia. Screening for major neurocognitive disorders can be helpful in designing and implementing early interventions.
