Abstract
Background: Naming impairment is mostly found in patients with stroke, epilepsy and neurodegenerative diseases. The Battery of Naming Tests, which includes the Visual Naming Test of the Multilingual Aphasia Examination and the Object Naming Test of the Neurosensory Center Comprehensive Examination for Aphasia, is a good task for measuring both oral expression performance and core linguistic functions. In addition, this battery has several advantages, such as a short administration time, simple instructions, and items of different categories and levels. However, there is currently a lack of normative data for the Battery of Naming Tests in the Taiwanese population. Objective: The present study aimed to obtain normative data for the Battery of Naming Tests. The specific objectives were as follows: (1) to assess the influence of demographic variables on test performance, (2) to establish psychometric properties, and (3) to determine norm appropriacy. Methods: Participants (N = 322) were recruited through stratified sampling by current age (ranging from 16 to 90 years old), education (ranging from 0 to 18 years), and area of residence. Thirty participants also completed the Vocabulary and Similarities subtests of the WAIS-III for investigation of the validity, and a clinical patient group was also recruited for verification of the validity. Test-retest reliability was derived from a subgroup of thirty participants. Results: Education significantly influenced performance of naming tests. The results also showed that the Battery of Naming Tests had sound construct validity and moderate test-retest reliability. The normative data showed good representativeness, recency, and relevance. Conclusion: The present study determined the influence of demographic effects on performance on the Battery of Naming Tests, established appropriate normative data, and developed a reference table for percentile ranks and a cut-off point. Despite the moderate test-retest reliability, this study verified the adequate validity of the Battery of Naming Tests. Further investigations on the test-retest reliability and the qualitative scoring system appear necessary in order to detect changes in oral expression and aphasic symptoms, and monitor the outcome of neurocognitive rehabilitation.
