Davis, Ramos, Sherer, Bertram and Wall looked at the sensitivity of the TOMM and WMT to malingering in two groups

On page 456 of the Archives of Clinical Neuropsychology conference abstracts (vol 24, issue 5, August 2009), there is a study by Davis, Ramos, Sherer, Bertram and Wall (2009).

They looked at the sensitivity of the TOMM and WMT to malingering in two groups, who were naive or coached simulators.

  • Sensitivity for the TOMM was a mean of 48% (59% for naive and 38% for coached simulators).
  • Sensitivity for the WMT was 71%< for both naive and coached simulators
  • Both the TOMM and WMT had 100% specificity in a control group making a good effort (using only pass/fail easy subtests).

Conclusion: The WMT was more sensitive to poor effort than the TOMM, especially in simulators who had been coached. They were equally specific in controls.
