The Indonesian Boston Naming Test: Normative Data among Healthy Adults and Effects of Age and Education on Naming Ability

The purpose of the current study was to introduce the Indonesian Boston Naming Test (I-BNT) and to present normative data for the BNT based on a sample of Indonesian adults. Two hundred healthy adults, ages range from 16 89 years old, participated in the current study. Relationships between BNT variable and demographic characteristics i. e. age, education, and gender were calculated using Pearsons correlation coefficient and t-test analysis for dichotomous variable. Both age and education were significantly associated with the BNT, and no gender differences were found. The inclusion of typical Indonesian target words and correct response analysis of items were also investigated. The obtained norms were shown to be relatively lower than published norms for comparable North-American adults, but slightly higher when compared to obtained BNT norms of other countries. Comparing the USA-BNT and I-BNT resulted in conclusion that the adapted I-BNT is appropriate for use in Indonesia, and the reordering of items reflecting difficulty-order of the items for Indonesian sample is presented for clinical use.
