Abstract

Objective

Determining the effort level allocated during a neuropsychological evaluation is essential, as effort has been shown to predict performance.

Method

One hundred and thirty-seven former NFL players were given the Test of Memory Malingering (TOMM) and Green’s Medical Symptoms Validity Test (MSVT) as part of a comprehensive neuropsychological evaluation.

Results

Based on established “cutoff” scores, 42 of the 137 individuals failed the TOMM (Trial 2, raw score < 45). Using the recommended “cutoff” scores, (Immediate recall, Delayed recall, Consistency <=85%, Paired Associated <=70%, Free recall<=50%), 74 individuals failed the MSVT. Together, the TOMM and the MSVT identified 81 individuals with sub-optimal effort and likely invalid neuropsychological test data, as both the TOMM and MSVT are passed by groups with known traumatic brain injury and other impairments.

Conclusions

We conclude that 59.1% of the Former NFL players put forth inadequate effort during testing. While the reasons for PVT failure are known only by the test-takers themselves, the validity of the results is highly questionable regardless and must be interpreted in this context.
