| Abstract: | This study was designed to examine the construct validity of the Wechsler Memory Scale–Fourth Edition (WMS–IV) in individuals with traumatic brain injury (TBI). One hundred individuals with TBI (n= 35 complicated mild/moderate TBI;n= 65 severe TBI) and 100 matched controls from the WMS–IV normative dataset completed the WMS–IV. Multivariate analyses indicated that severe TBI participants had poorer performance than matched controls on all index scores and subtests. Individuals with complicated mild/moderate TBI performed more poorly than controls on all index scores, as well as on tests of visual memory (Designs I and II; Visual Reproduction I and II) and visual working memory (Spatial Addition; Symbol Span), but not on auditory verbal memory tests (Logical Memory I and II; Verbal Paired Associates I and II). After controlling for time since injury, severe TBI participants had significantly lower scores than the complicated mild/moderate TBI on 4 of the 5 WMS–IV index scores (Auditory Memory, Visual Memory, Immediate Memory, Delayed Memory) and 4 of the 10 WMS–IV subtests (Designs I and II, Verbal Pairs II, Logical Memory II). Effect sizes for index and subtest scores were generally moderate for the complicated mild/moderate group and moderate-to-large for the severe TBI group. Findings provide support for the construct validity of the WMS–IV in individuals with TBI. [ABSTRACT FROM PUBLISHER] |
