All participants underwent a comprehensive neuropsychological assessment that included the CP-BNT. Factor analysis and item response theory were conducted.</p><p><strong>Results: </strong>The CP-BNT exhibits a multidimensional structure with three factors: Factor 1, consisting of nine items with moderate difficulty levels, demonstrated peak measurement function for mild anomia (the highest information value = 33.7, ability estimated value = -0.8, reliability = 0.97); Factor 2, comprising eleven items with lower difficulty levels, performed well in cases of mild to moderate anomia (the highest information value = 34.1, ability estimated value = -1.2, reliability = 0.97); and Factor 3, including ten items with higher difficulty levels, provided the most measurement information for normal naming (the highest information value = 9.9, ability estimated value = 0, reliability = 0.90). All items, except item <i>igloo</i>, showed good discrimination (discrimination parameter ranged from 5.46 to 1.15). Most items had a different difficulty position versus the original version, thereby generating a novel item sequence with an ascending difficulty hierarchy for Chinese samples.</p><p><strong>Conclusions: </strong>These findings support that the CP-BNT has good validity, reliability, and cultural appropriateness in the Chinese context, improving its utility in clinical assessments and interventions.</p>","PeriodicalId":14929,"journal":{"name":"Journal of Alzheimer's Disease","volume":" ","pages":"13872877241305820"},"PeriodicalIF":3.4,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142836553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
