Abstract

Objective: This study explored using the FIT as a measure of performance validity among veterans undergoing neuropsychological evaluation for mild traumatic brain injury (mTBI).

Background: The Rey Fifteen-Item Memory Test (FIT) is a performance validity measure criticized for poor sensitivity.

Methods: Two hundred and fifty-seven veterans completed the FIT and Wechsler Adult Intelligence Scale, Fourth Edition, Digit Span (DS); 109 of whom completed the Test of Memory Malingering (TOMM). FIT cut-offs of <9, <8 and stricter cut-offs were examined using DS and/or TOMM as criterion performance validity measures.

Results: Only four participants scored below the standard cut score of 9 on the FIT. Among the 13 veterans failing both criterion tests, only two scored below 9 on the FIT. Regardless of which FIT cut-off was used, the FIT had poor diagnostic accuracy.

Conclusion: Despite its popularity, the FIT is not supported as an appropriate measure of performance validity in veterans undergoing evaluation for possible mTBI. Therefore, inferences regarding neuropsychological data reliability with adequate statistical certainty require use of other measures of performance validity with greater sensitivity.
