We created a modified version of the Mini-Mental State Examination (MMSE) for persons with hearing loss (HL) and tested its reliability, validity and effectiveness among 40 elderly participants. We extracted the MMSE items `registration', `recall', `repetition' and `comprehension' and in the HL condition, these four items were only presented with simultaneous spoken and written instructions. The results were as follows: (1) The HL test-retest coefficient of correlation was r = 0.74; Cronbach's α was 0.64. (2) In the non-hearing loss group, the HL test results showed a correlation with the MMSE, the Oldest-Old version of the Cognitive Assessment Questionnaire and the Clinical Dementia Rating(CDR-J). (3) A 2-way ANOVA was conducted with cognitive function as the within-subjects factor and hearing loss as the between-subjects factor; for total score, `registration' and `repetition', the effect of cognitive function test was significant only in the hearing loss group. The retest reliability of HL, its concurrent validity and its effectiveness were confirmed. It is desirable to administer the standard MMSE to persons with hearing loss if they can use hearing aids or adjustments can be made to the volume. However, if such modifications are not possible, HL may be useful in cases where it is necessary to repeat questions.
