Montreal Cognitive Assessment alternate-form reliability cognitive screener test–retest reliability. Comparisons of the domain-specific scores should be interpreted with caution.Key pointsThe MoCA total score is a reliable cognitive measure.All three MoCA versions are largely equivalent.Age, education and intelligence are predictors of MoCA performance in healthy participants.Future studies should focus on collecting normative data for age, education and intelligence for use in clinical practice. All three MoCA versions are largely equivalent based on MoCA-TS and the test-retest reliabilities show that this score is suitable to monitor cognitive change over time. Conclusion: Adequate norms are needed that take the effects of age, education and intelligence on MoCA performance into account. MoCA has been subsequently adopted in clinical settings around the world and is widely used as a scale in academic and non-academic research. For the MoCA-MIS, coefficients were poor (ICC: 0.32) to fair (ICC: 0.48), respectively. MoCAalso known as Montreal Cognitive Assessment or The MoCA Testwas validated as a highly sensitive tool for early detection of mild cognitive impairment (MCI) in 2000. Test-retest reliability of the MoCA-TS was good between 7.1 and 7.2 (ICC: 0.64) and excellent between 7.1 and 7.3 (ICC: 0.82). Systematic differences between MoCA version 7.1 and alternate versions 7.2 and 7.3 were only found for the items animal naming, abstract reasoning and sentence repetition. Results: Age, education and estimated premorbid intelligence correlated significantly with the total score (MoCA-TS) and the Memory Index Score (MoCA-MIS). Method: In 210 participants, two MoCA versions and an estimator for premorbid intelligence were administered at two time points. Aims of the current study were to examine the effects of age, education and intelligence on MoCA performance and to determine the alternate-form equivalence and test-retest reliability of the MoCA, in a group of healthy participants. Mini Mental State Examination.Objectives: The Montreal Cognitive Assessment (MoCA) is a cognitive screen, available in three alternate versions. We conclude that both tests have adequate psychometric properties as a screening instrument for the detection of KS, but the MoCA is superior to the MMSE for this specific patient population.Īlcoholism Amnesia Cognitive screening Korsakoff’s syndrome. As a screening instrument with the most optimal cut-offs, the MoCA (optimal cutoff point 22/23, 98.3% correctly diagnosed) was superior to the MMSE (optimal cutoff point 26/27, 83.3% correctly diagnosed). When applying a cut-off value as suggested in the manuals of both instruments, the MMSE (< 24) misdiagnosed 46.7% of the patients, while the MoCA (< 26) diagnosed all patients correctly. Compared with the MMSE, the MoCA demonstrated consistently superior psychometric properties and discriminant validity-AUC: MoCA (1.00 SE. The area under the receiver operating characteristic curve (AUC) was calculated in addition to the sensitivity, specificity, positive predictive value, and negative predictive value for various cut-off points on the MoCA and MMSE. A representative sample of 30 patients with KS and 30 age-, education-, gender- and premorbid-IQ-matched controls was administered the MoCA and MMSE. KS is a chronic neuropsychiatric disorder associated with profound declarative amnesia after thiamine deficiency. Although these instruments have frequently been used in the detection of dementia, there is currently little knowledge on the validity to detect Korsakoff's syndrome (KS) with both screening instruments. The Montreal Cognitive Assessment (MoCA) and Mini Mental State Examination (MMSE) are brief screening instruments for cognitive disorders.
