Signs and symptoms of sport-related concussion can include cognitive dysfunction and are frequently treated by speech-language pathologist (SLPs). SLPs provide most cognitive rehabilitation in the United States, but report marked challenges in concussion assessment, lacking an adequate evidence-base for measurement tools. Speech-pathologists and researchers use the Woodcock-Johnson (WJ) to assess neurocognitive and linguistic function in concussion, though there is no literature using WJ pre- and post-concussion. This dissertation had the following aims: 1) Establish WJIII/WJIV normative samples for club-level collegiate athletes playing high-contact sports; 2) Evaluate influence of collegiate year on WJ performance; 3) Measure change in neurocognitive-linguistic functioning after sport-related concussion; 4) Explore the relationship between WJ and self-reported symptoms post-injury. The baseline cohort had 814 athletes, and 91 met post-injury criteria. There were no statistical differences for adjusted mean performance compared to published norms, although speeded test performances were above norms. WJIV performance was superior to WJIII for parallel subtests. There was no performance growth by academic year, though subsequent information revealed the WJ scoring algorithm modifies scores based on collegiate year, flattening possible improvement. Sex-based differences emerged with women consistently outperforming men, including on categorical naming and reading comprehension. Post-injury performance was analyzed with regression for WJIII and descriptive statistics for WJIV. Post-concussion, the symptomatic group had negative mean performance on all WJIII subtests, including word finding, reading comprehension, and verbal memory. Negative predictors of clearance status, male sex, and baseline performance emerged. There was a similar descriptive pattern for WJIV. Kappa correlations for WJIII performance and self-reported symptoms were poor, indicating that WJII performance and symptom self-report are measuring somewhat disparate elements. The sensitivity and specificity of the combined WJIII-symptom battery was strong (0.98, 95%CI=0.89-0.99; 0.92, 95%CI=0.62-0.99) as were likelihood ratios (PLR = 14.71; NPR 0.02). This study is the first publication documenting pre-post sport-related concussion performance changes, using an existing clinical battery, readily available to SLPs. Gold standard symptom scales inadequately assess potential cognitive-communication changes after sport-related concussion. The strong clinical relevance of these findings in the context of concussion care is discussed, and additional future clinical research is needed to expand study findings.
