CBEMS could promote a culture conducive to increased reporting behavior, which makes the campus safer. Similar BAC levels suggest that the degree of intoxication was similar for the 2 reporting periods, but students sought emergency assistance more frequently following the inception of CBEMS.

Objective Understanding sex and sport-related differences in baseline neurocognitive scores may aid in interpreting post-injury performance. Sex and sport-related differences in neurocognitive performance for collegiate athletes have not been examined on the NIH Toolbox® Cognition Battery (NIHTB-CB). Therefore, this study sought to determine if baseline scores on the NIHTB-CB differ between sex or sport in collegiate athletes. It was hypothesized that sex, but not sport-related differences would exist in CB baseline performance. Method 107 Division-I athletes (47 females, 60 males) that participated in soccer (n = 45), football (n = 30), or cheerleading (n = 32) volunteered to participate. Participants completed tablet-based NIHTB-CB assessments including the Flanker Inhibitory Control & Attention (FICA), Dimensional Change Card Sort (DCCS), Picture Sequence Memory (PSM), and Pattern Comparison Processing Speed (PCPS) tests. These assessments measured visual attention, cognitive flexibility, memory recall, and processing speed, respectively. Fully corrected t-scores were used for analyses. Parametric and non-parametric tests compared scores based on sex and sport. Results Females demonstrated greater performance on the PCPS (Females: 64.72 ± 9.84, Males: 61.08 ± 8.85; p = 0.006). Males exhibited better performance on the FICA (Females: 45.72 ± 10.12, Males: 51.03 ± 10.70; p = 0.009). After controlling for sex, a significant difference across sports was identified in the FICA (p = 0.007) with cheerleading (43.81 ± 9.28) exhibiting poorer performance than football (54.33 ± 10.44; p = 0.002) and soccer (48.42 ± 10.28; p = 0.047). No sex or sport differences were identified for the DCCS or PSM. Conclusions Baseline differences in neurocognitive performance exist on the NIHTB-CB based on sex and sport suggesting these variables be taken into consideration when interpreting post-concussion scores in collegiate athletes.
