ObjectiveEducation is expected to have an effect on differential item functioning (DIF) on the 15-item Modified Boston Naming Test in the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet (BNT-KC). However, no study has examined DIF in the BNT-KC. MethodsWe used the item response theory to investigate the impact of education on the DIF in the BNT-KC among elderly individuals with or without dementia (n=720). A two-parameter item response model was used to determine the difficulty and discrimination parameters of each item. The Benjamini-Hochberg procedure was used to address the risk of Type I errors on multiple testing. ResultsFour items, “mermaid,” “acorn,” “compass,” and “pomegranate” continued to demonstrate DIF after controlling for multiple comparisons. Those with low education levels were more likely to error on “mermaid” and “compass,” while those with high education levels were more likely to error on “acorn” and “pomegranate.” “Hand” and “red pepper” were too easily identified to be used for detecting dementia patients. “Monk's hat” and “pomegranate” were less discriminating than other items, limiting their usefulness in clinical setting. ConclusionThese findings may provide useful information for the development of a revised version of the BNT-KC to help clinicians make diagnostic decisions more accurately.
