| MoCA Version | Internal Consistency | Test-Retest Reliability | Sensitivity | Specificity | Administration Time | Notes / Key Points |
|---|---|---|---|---|---|---|
High (α ≈ 0.83–0.90) | Good over 1–3 months | High for MCI and dementia | Moderate to high | ~10–15 min | Validated across multiple populations and languages; cutoff scores vary by population. | |
Moderate to high | Moderate to high | Adequate for MCI and dementia | Adequate | ~10–15 min (+2–3 min setup) | Administered remotely via videoconference; responses verbal or shown on paper; suitable for neurological and older adult populations. | |
Good (α ≈ 0.80) | Good | Moderate to high | Moderate | ~5 min | Telephone-based screening; validated in diverse populations; suitable for telemedicine. | |
Good | Preliminary evidence supports stability | High for cognitive prescreenin g | High | ~5 min | Self-administered digital pre-screening; suitable for telehealth; ongoing validation studies. | |
Good | Good | High in low-education/ illiterate populations | Moderate to high | ~10–15 min | Simplified instructions, literacy-independent tasks; validated in low-educated, illiterate, and culturally diverse populations. | |
High | Good | Adequate for MCI and dementia | High | ~10–15 min | Adapted for hearing-impaired; ensures assessment reflects cognition rather than hearing; available in multiple languages. | |
High | Good | Adequate | Adequate | ~10–15 min | Uses auditory or tactile stimuli; preserves all cognitive domains; suitable for visually impaired individuals. | |
High | Good to excellent | Adequate to high for cognitive impairment | Adequate to high | ~10–15 min | Uses only auditory items; designed for blind individuals; validated with normative data across multiple countries; reliable change indices available; preserves assessment of all cognitive domains |
