This work used a large test battery to identify measures that explained the most variability across participants with and without a history of head injury, to determine relationships between measures, and to explore patterns of performance across participants, with the aim of identifying measures that should be considered in future research on developing clinical assessment protocols for this unique patient population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method:<\/jats:title>\n                    <jats:p>A principal component analysis was conducted on data from 22 self-report, central auditory processing, and cognitive processing measures completed by a sample of 95 participants.

However, analyses revealed that performance on the behavioral auditory processing tests was not predictive of self-reported auditory and non-auditory symptom severity. A cluster analysis further revealed spread in performance across participants with a history of blast exposure or nonblast mTBI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Results from the current study underscore the need for a comprehensive, individualized approach to patient care for those with a history of head injury.
