Children with severe TBI easily pass but adults with mild TBI fail: How can that be?

Carone, D. Children with moderate/severe brain damage/dysfunction outperform adults with mild to no brain damage on the Medical Symptom Validity Test. Brain Injury, 2008; 22, 12, 960-971. 

WMT failures in mild TBI are not false positives:

Brain Injury, August 2009; 23(9): 741750

TOMM, MSVT, Rey-15-Item Test and Reliable Digit Span in children with good effort versus simulators.

MSVT has very few false positives for poor effort in dementia, as long as the dementia profile is included in the analysis of results. Also, the MSVT can be used as an aid to diagnosis in dementia.

Effects of effort dwarf the effects of brain injury on neuropsychological tests.

Response Bias Scale:A new scale for the MMPI-2 measures exaggeration of cognitive complaints:

Extensive data show that it is external incentive and not ability that accounts for WMT failure in non-demented people:

Flaro, L., Green, P. & Robertson, E. (2007) Word Memory Test failure 23 times higher in mild brain injury than parents seeking custody: The power of external incentives. Brain Injury, 21, 4, 373-383.

Effort testing by physicians:

Bowden and Shores data show more Word Memory Test failures in mild than in severe brain injury

This conclusion, drawn directly from their raw data, is contrary to the claims in their published paper in TCN.

Seizures versus pseudoseizures: Important new work by Dr. Daniel Drane, D.J. Williamson et al. at the Seattle Brain Surgery Program. This study involves effort testing with WMT in patients with seizure disorders versus psychogenic nonepileptic seizures (formerly pseudo-seizures).

Effort versus brain injury: This paper contains numerous tables showing how effort on the WMT predicts neuropsychological test scores better than brain injury severity.

Authors of the latter paper were presented with the Nelson Butters Award at the National Academy of Neuropsychology annual conference in Dallas, USA, October, 2003. It was based on Dr. Green's testing of 680 consecutive outpatients and the finding that, after removing cases showing "response bias", depression had no effect on any of 43 neuropsychological test scores.
