title: WMS-III findings in litigants following moderate to extremely severe brain trauma.
abstract: Published information pertaining to the clinical utility of the WMS-III in assessing memory impairment in traumatic brain injury (TBI) remains inadequate. WMS-III findings are reported for 180 litigants with post-acute moderate to extremely severe TBI, classified into three groups according to injury severity, and a healthy control group. A significant "dose-response" relationship was found between memory impairment and TBI severity for most of the WMS-III indexes and subtests. Effect sizes were large for the Immediate and General Memory Indexes and medium for the Working Memory Index. In general, TBI had a greater effect on the Visual than Auditory Indexes. Effect sizes were greatest for Family Pictures and least for the auditory recognition and working memory tasks. Group findings indicate the immediate memory tasks to be clinically useful in relation to a severe or extremely severe TBI, but not for less severe trauma. Delayed memory tasks do not provide information additional to that obtained from immediate memory measures. The revised Tulsky indexes are no more sensitive to the effects of TBI than the original ones. Differences between WMS-III memory indexes are unlikely to be of diagnostic utility although memory-intelligence discrepancies may be.
