Examining Cognitive Complaints vs. Neuropsychological Test Performance After Military-Related TBI

This study investigates the relationship between self-reported cognitive complaints and neuropsychological test performance in U.S. servicemembers following military-related traumatic brain injury (TBI). Analyzing 109 participants, we found significant correlations between cognitive complaints and psychological distress, but not with overall neurocognitive functioning. Notably, many participants reported cognitive issues despite having normal neurocognitive test scores. These findings highlight the importance of understanding psychological factors in cognitive assessments post-TBI, suggesting that clinicians should consider both self-reports and objective measures in TBI care.

  2. Aim • Examine relation between neuropsychological test performance and self-reported cognitive complaints following traumatic brain injury (TBI). • Relevance • TBI care focuses on ameliorating self-reported symptoms, modifying environmental factors, and improving clinician-observed deficits. • However, limitations of self-reported symptoms could reduce reliability of this information.

  3. Method • Participants • 109 U.S. servicemembers. • Completed neuropsychological evaluation within first 2 yr following mild–severe TBI. • Measures • Personality Assessment Inventory. • Posttraumatic Stress Disorder Symptom Checklist-Civilian version. • Neurobehavioral Symptom Inventory. • 17 measures corresponding to memory, attention/ concentration, and processing speed/organization.

  4. Results • Self-reported cognitive complaints: • Significantly correlated with psychological distress. • Not significantly correlated with overall neurocognitive functioning. • Low agreement between neurocognitive test scores and self-reported cognitive complaints. • For large minority of sample, self-reported cognitive complaints were reported in presence of neurocognitive test scores within normal limits.

  5. Conclusion • While self-reported cognitive complaints were not associated with neurocognitive test performance, they were associated with psychological distress. • These results provide information to contextualize cognitive complaints following TBI.
