A comprehensive evaluation, including the assessment of neurobehavioral symptoms,
has been instituted at the Department of Veterans Affairs (VA) healthcare system
to address the large number of Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) Veterans returning with mild traumatic brain injuries (mTBIs). The
Validity-10 is measure of symptom overreporting embedded within the
Neurobehavioral Symptom Inventory, a component of the comprehensive evaluation
that assesses postconcussive symptom severity. The Validity-10 is composed of 10
unlikely/low-frequency items and a validated cutoff score to identify
postconcussive symptom overreporting. We examined the items and cutoff used in
the initial development and validation study of the Validity-10 through
retrospective chart reviews of 331 treatment-seeking Veterans who sustained an
mTBI. The Validity-10 exhibited significant relationships with psychiatric
variables, VA service connection, and neuropsychological performance validity
(all p < 0.01), but nonsignificant relationships with demographic and injury
variables (all p > 0.05). Furthermore, the Validity-10 modestly predicted
neuropsychological performance validity test failure over and above psychiatric
comorbidities and VA service connection. The present study supports the use of
the Validity-10 to assess symptom validity in treatment-seeking OIF/OEF Veterans
with a history of mTBI.
