Abstract — This study examined the relation between neuropsychological test performance and self-reported cognitive complaints following traumatic brain injury (TBI). Participants were 109 servicemembers from the U.S. military who completed a neuropsychological evaluation within the first 2 yr following mild–severe TBI. Measures included the Personality Assessment Inventory (PAI), Posttraumatic Stress Disorder Symptom Checklist-Civilian version (PCL-C), Neurobehavioral Symptom Inventory (NSI), and 17 select measures from a larger neurocognitive test battery that corresponded to three self-reported cognitive complaints from the NSI (i.e., memory, attention/concentration, and processing speed/organization). Self-reported cognitive complaints were significantly correlated with psychological distress (PCL-C total: r = 0.50–0.58; half the PAI clinical scales: r = 0.40–0.58). In contrast, self-reported cognitive complaints were not significantly correlated with overall neurocognitive functioning (with the exception of five measures). There was a low rate of agreement between neurocognitive test scores and self-reported cognitive complaints. For the large minority of the sample (38.5%–45.9%), self-reported cognitive complaints were reported in the presence of neurocognitive test scores that fell within normal limits. In sum, self-reported cognitive complaints were not associated with neurocognitive test performance, but rather were associated with psychological distress. These results provide information to contextualize cognitive complaints following TBI.
Key words: cognitive complaints, military, Neurobehavioral Symptom Inventory, neurocognitive measures, Personality Assessment Inventory, psychological distress, PTSD Checklist, self-reported symptoms, servicemembers, traumatic brain injury.
