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.
