Background: Occupational therapists often assess clients’ cognitive skills. It is important for therapists to make informed decisions and choose the most appropriate and robust cognitive assessment.Aim: To explore the association between performance on the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) among patients in a subacute inpatient setting.Methods: A total of 20 participants (11 men, 9 women; mean age, 82 years; SD = 6.93) were recruited from a geriatric evaluation and management ward in an Australian hospital. Cognitive ability was assessed with the MMSE and MoCA. Spearman’s rho correlation analysis with bootstrapping was completed. Results: Statistically significant associations were found between MMSE and MoCA total scores (rs = .63, p < .01),orientation subscale scores (rs = .65, p < .01), and attention subscale scores (rs = .76, p < .01). Other statistically significant correlations were found between MMSE and MoCA subscale scores.Conclusion: The MoCA appears to be a valid measure that can be used to evaluate cognitive status in a subacute geriatric evaluation and management setting. A small sample size and the use of convenience sampling were the main limitations of the study. Further studies with a larger sample are recommended to confirm these findings.
