Abstract
Background: The Benton Visual Retention Test (BVRT) is increasingly utilized within research and clinical settings to assess visual perception, visual memory, and visuoconstructive ability due to its convenience to use, short administration time, and the availability of multiple parallel forms. However, the current available norms with questionable representativeness of samples, lack of examination of relations between the demographic variables and the test, and lack of examination of psychometric properties limits the utility. Objective: The present study was aimed to establish a norm for the BVRT. The specific objectives were to investigate: (1) the influences of demographic variables on the test, (2) the issue of psychometric properties, and (3) the issue of norm appropriacy. Methods: 308 participants 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. Some participants were additionally administered the Visual Reproduction subtest of WMS-III and the Visual Form Discrimination Test to investigate the validity. Clinical Patient group was also recruited for verifying the validity. The test-retest and the alternate-forms reliability were also derived from a subgroup of participants. Result: The effects of age and education rather than gender were significant on the BVRT performance. The results also showed sound test-retest reliability, criterion-related validity, and the construct validity of the BVRT, with the exception of moderate alternate-forms reliability. The normative data have good representativeness, recency, and relevance. Conclusion: The present study identified the influences of demographic effects on the BVRT performances, established an appropriate normative data for evaluating the visual memory, and provided the referential table for percentile ranks. Despite the fact that the alternate-forms reliability was not as high as expected from Taiwanese samples, this study also verified the adequate reliability and the validity of the BVRT. It is useful for early detection, differential diagnosis, treatment evaluation, and prognosis. Further investigation on the issue of the alternate-forms reliability and the normative data of the Forms D and E are necessary.
