Domain: Psychological

Assessment Tool Category: Dementia/Alzheimer’s

Variations/Translations: Translated into a number of languages including Canadian French.

Setting: Clinical setting

Availability: The MoCA test and instructions are available through the website listed below (www.mocatest.org) in a number of different languages. For clinical and educational use, the MoCA may be reproduced without permission, by universities, foundations, health professionals, clinics, and public health institutes. Written permission and Licensing Agreement is required if funded by commercial entity or pharmaceutical company. Written permission is required for universities, foundations, health professionals, clinics, and public health institutes, commercial entities, and pharmaceutical companies if MoCA is being used for research purposes. In all cases, MoCA is available free of charge.

Quantitative/Qualitative: Quantitative

Validity (Quantitative): In a study by the original test authors, the MoCA was administered to three groups: Alzheimer’s disease (AD) patients, mild cognitive impairment (MCI) patients, and normal elderly controls. Results showed that all test items were capable of discriminating between at least two of the groups, in the expected direction (p < 0.001). Content validity was assessed by comparing scores from MoCA and the Mini-Mental State Exam (MMSE) and correlation was found to be high (r = 0.87). Sensitivity was found to be high for identifying both AD and MCI patients (100% and 90%, respectively). The specificity of the MoCA (defined as the ability to identify non-cognitively impaired subjects) was 87%. Positive and negative predictive values were also high for both AD patients (89% and 100%, respsectively) and MCI patients (89% and 91%, respectively). The MoCA was determined to be useful for screening for mild stages of cognitive impairment (including MCI and mild AD), while not as useful as the MMSE for assessing more advanced stages of AD. The MoCA was developed simultaneously in English and French (Canadian) and the two language forms were found to be equivalent (scores did not differ significantly, p = 0.91) (Nasreddine, Phillips, Bédirian, Charbonneau, Whitehead, Collin, et al, 2005).

Reliability (Quantitative): Test-retest reliability (patients tested 35 days apart) was high, with an intraclass correlation coefficient of 0.92. The internal consistency was also found to be high (Cronbach alpha on standardized items = 0.83) (Nasreddine et al., 2005).
