Conférence MoCA #23 :
De JAMA à GUIDE : 20 ans de parcours pour faire progresser les soins aux personnes atteintes de démence (Malaz Boustani, MD, MPH) - jeudi 5 juin 2025, 12 h 00 HAE
The MoCA-Basic is a version of the MoCA designed for individuals with low education levels or limited literacy. Education-dependent and literacy-reliant tasks have been replaced with suitable alternatives, while preserving the assessment of all major cognitive domains.
Purpose: It is designed to screen for mild cognitive impairment in individuals with limited literacy or educational background, ensuring that test results reflect cognitive abilities rather than educational factors, with the original validation study conducted in participants who had fewer than five years of formal education.
Administration time
Approximately 15 minutes.
Setting
The MoCA-Basic should be administered in a clinical setting or other calm, controlled, distraction-free environment.
Form
Paper-based; the examiner presents standardized stimuli and records the examinee’s responses directly on the test sheet.
Cost
Freely available for clinical and educational use; a license is required for commercial use.
The MoCA-B is scored manually, in accordance with the guidelines provided in the instructional PDF. The total score ranges from 0 to 30 points, with higher scores indicating better cognitive functioning. Scores of 25 or higher are generally considered within normal limits.

| Property | Summary of Findings Across Studies | Typical Values / Ranges | Interpretation |
|---|---|---|---|
Sensitivity to Cognitive Impairment | Detects MCI and dementia effectively in individuals with low literacy or limited education. | 80–90%+ | Strong ability to identify cognitive impairment in populations where traditional tests underperform. |
Specificity | Moderate to high specificity across studies. | 70–85% | Acceptable rate of false positives; reliable for ruling out impairment. |
Diagnostic Accuracy (AUC) | Demonstrates strong discriminative validity across cultures. | 0.80–0.93 | High overall accuracy in distinguishing impaired from non-impaired individuals. |
Education Independence | Minimal influence of literacy or educational level on test performance. | - | Appropriate for low-educated or illiterate examinees without risk of underestimation. |
Reliability | Good internal consistency and test–retest stability. | ICC 0.80–0.90; α ≥ 0.75 | Scores are consistent and reproducible across administrations. |
Cross-Cultural Validity | Validated across multiple countries with stable psychometric properties. | - | Suitable for diverse linguistic and cultural settings. |
Comparative Performance | More sensitive than MMSE; avoids floor effects of MoCA Full in low-education groups. | - | Superior option for screening cognitive impairment in low-literacy populations. |
