A cross‐cultural study of the Montreal Cognitive Assessment for people with hearing impairment

Abstract

AbstractBackgroundCognitive screening tools enable the detection of cognitive impairment, facilitate timely intervention, inform clinical care, and allow long‐term planning. The Montreal Cognitive Assessment for people with hearing impairment (MoCA‐H) was developed as a reliable cognitive screening tool for people with hearing loss. Using the same methodology across four languages, this study examined whether cultural or linguistic factors affect the performance of the MoCA‐H.MethodsThe current study investigated the performance of the MoCA‐H across English, German, French, and Greek language groups (n = 385) controlling for demographic factors known to affect the performance of the MoCA‐H.ResultsIn a multiple regression model accounting for age, sex, and education, cultural–linguistic group accounted for 6.89% of variance in the total MoCA‐H score. Differences between languages in mean score of up to 2.6 points were observed.ConclusionsCultural or linguistic factors have a clinically significant impact on the performance of the MoCA‐H such that optimal performance cut points for identification of cognitive impairment derived in English‐speaking populations are likely inappropriate for use in non‐English speaking populations. To ensure reliable identification of cognitive impairment, it is essential that locally appropriate performance cut points are established for each translation of the MoCA‐H.
