ABSTRACT
BACKGROUND:
The Boston Naming Test (BNT) is the most widely used measure to assess anomia. However, it has been criticized for failing to differentiate the underlying cognitive process of anomia.OBJECTIVE:
We validated the color-picture version of BNT (CP-BNT) in a sample with diverse neurodegenerative dementia diseases (NDDs). We also verified the differential ability of the composite indices of CP-BNT across NDDs groups.METHODS:
The present study included Alzheimer's disease (nâ=â132), semantic variant primary progressive aphasia (svPPA, nâ=â53), non-svPPA (nâ=â33), posterior cortical atrophy (PCA, nâ=â35), and normal controls (nâ=â110). We evaluated psychometric properties of CP-BNT for the spontaneous naming (SN), the percentage of correct responses on semantic cuing and word recognition cuing (% SC, % WR). Receiver operating characteristic analysis was used to examine the discriminatory power of SN alone and the composite indices (SN, % SC, and % WR).RESULTS:
The CP-BNT had sufficient internal consistency, good convergent, divergent validity, and criterion validity. Different indices of CP-BNT demonstrated distinct cognitive underpinnings. Category fluency was the strongest predictor of SN (ß=â0.46, pâ<â0.001). Auditory comprehension tests highly associated with % WR (Sentence comprehension ß=â0.22, pâ=â0.001; Word comprehension ß=â0.20, pâ=â0.001), whereas a lower visuospatial score predicted % SC (ß=â-0.2, pâ=â0.001). Composite indices had better predictability than the SN alone when differentiating between NDDs, especially for PCA versus non-svPPA (area under the curve increased from 63.9% to 81.2%).CONCLUSION:
The CP-BNT is a highly linguistically relevant test with sufficient reliability and validity. Composite indices could provide more differential information beyond SN and should be used in clinical practice.Palavras-chave
