Rates of Performance Validity Test Failure for ADHD Evaluations in a Military Population: An Exploratory Study.

OBJECTIVE: Investigate rates of Performance Validity Test (PVT) failures in a group of active duty (AD) military participants referred for ADHD evaluations and other characteristics of those referred for evaluation.

METHOD: AD service members referred for ADHD evaluations were given PVTs as part of assessment. PVT pass/fail groups were compared on age, estimated premorbid intelligence, history of ADHD, other mental health problems, and functional impairment.

RESULTS: PVT failure rate was consistent with other studies. Fail group was younger and lower estimated premorbid intelligence than those that passed. Groups based on other variables did not significantly differ. Failure group also performed worse on a measure of attention. Many individuals were referred with no childhood history of ADHD or objective evidence of impaired function.

CONCLUSION: Rates of PVT failures were similar to those found in civilian university and veteran military settings. Screening candidates for specific Diagnostic and Statistical Manual of Mental Disorders (5th ed.) criteria for ADHD was only minimally followed.
