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.

On the DP IQ, average scores were in keeping with the general population mean across all groups but range was severely restricted. OPIE-3 IQ scores were not subject to severe range restriction and were comparable with the general population mean in the control and least severely brain injured group.

The base rate for probable MND in the population studied was 27%. Overall, malingerers showed globally depressed memory function.

There was a significant "dose response" relationship between TBI severity and all Index/IQ scores. Effect size was greatest for the Processing Speed Index (PSI).
