Objective:
Recent studies have begun to explore the role of psychological resilience in pediatric mTBI recovery, with findings associating higher levels of resilience with shorter recovery and lower levels of resilience mediated by pre-injury anxiety and depression associated with persistent symptoms. The purpose of this study is to extend the current literature by further exploring the relationship between resilience, post-injury emotional changes, and length of recovery from pediatric mTBI. Based upon previous literature, we predicted that resilience would explain a unique portion of the variance in length of recovery above and beyond acute post-injury emotional symptoms in adolescents recovering from mTBI compared with orthopedic injured (OI) controls.
Participants and Methods:The current study pulled data from a larger project utilizing a prospective cohort design in two cohorts of high school student-athletes aged 14-18 (N = 32). Participants with mTBI (n = 17) or OI (n = 15) sustained during sport were recruited within 10 days of injury from a quaternary care setting. Participants completed a neuropsychological screening evaluation within one week of enrollment, including self-report rating scales of resilience (Connor-Davidson Resilience Scale-10; CD-RISC) and self- and parent-reported post-concussion symptoms (Post-Concussion Symptom Inventory, Second Edition; PCSI-2). Hierarchical regression analysis was performed with days from injury to recovery as the dependent variable. Predictors were entered in three steps: (1) group (mTBI/OI) and sex, (2) PCSI self- and parent-reported post-injury change in emotional symptoms, and (3) CD-RISC raw score. Bonferroni correction was utilized to control for multiple comparisons.
Results:Group and sex did not provide significant prediction when entered into the first block of the model (p= .61). Introducing PCSI emotional ratings in the second block showed statistically significant improvement, F (2,26) = 5.12, p< .01), accounting for 31% of the variance in recovery length. Addition of the CD-RISC in the third block was not statistically significant (p=.59). Post hoc testing indicated parent ratings on the PCSI were significantly associated with recovery length t(32) = 3.16, p < .01, while self-reported ratings were not (p=.54).
Conclusions:Findings indicated that psychological resilience did not explain a unique portion of the variance in length of recovery above and beyond acute parent report of postinjury emotional symptoms in adolescents recovering from mTBI compared with orthopedic injured (OI) controls. Interestingly, sex, group (mTBI vs. OI), and self-reported acute postinjury emotional symptoms were not significant predictors of recovery length in this sample. Results highlight the significant role of acute changes in emotional symptoms in adolescents recovering from mTBI and OI in predicting length of recovery, as well as the importance of obtaining separate caregiver report. A more robust understanding of factors contributing to recovery from injury can help inform and improve preventive measures and treatment plants for those at risk or impacted; however, psychological resilience may not uniquely contribute to predicting length of recovery in acutely injured adolescents, limiting value added to the clinical exam. Future studies should explore the relationship between type of injury and recovery time in larger samples.

Objective:
Evidence-based consensus in children and adolescents following uncomplicated mTBI indicates acute cognitive symptoms resolve over time with minimal long-term impact. However, traditional paper-and-pencil neuropsychological measures used in many studies have been criticized for lacking sensitivity to subtle changes in attention and executive functions. The National Institutes of Health Toolbox Cognition Battery (NIHTB-CB) is a computerized tool assessing overall cognition, fluid cognition, and crystallized cognition with few studies in pediatric mTBI. The aim of this study is to continue to explore the utility of the NIHTB-CB in adolescents recovering from mTBI compared to orthopedic injuries (OI) and healthy controls (HC).
Participants and Methods:The current pilot study utilized a prospective cohort design with longitudinal follow-up in three cohorts of high school student-athletes aged 14-18 (N= 52). Participants with mTBI (n= 17) or OI (n= 15) sustained during sport were recruited within 10 days of injury from a quaternary care setting. An age- and gender-matched cohort of healthy controls (HC) in an active sport season was included for community comparison (n= 20). The NIHTB-CB was administered as part of a neuropsychological screening battery at enrollment and one month after medical clearance (mTBI and OI) or eight weeks after enrollment (HC).
Results:Results of a 3(group) x 2(time) ANOVA revealed a main effect of time (p < .001), but not group (p = .06), on the overall Fluid Cognition Composite. The mTBI group showed significantly lower performance on a measure of attention/inhibitory control (Flanker) compared to healthy controls acutely post-injury (p = .04; d = 0.72) and following clinical recovery (p < .01; d = 0.98), with no decline observed in the magnitude of group differences over time. The mTBI and OI groups exhibited deficits in performance on a measure of cognitive flexibility (Dimensional Change Card Sort) compared to the HC group acutely post-injury (both p < .01; d = 1.09-0.93). The magnitude of group differences between the OI and HC groups declined over time (p > .05; d = 0.68), whereas the mTBI group continued to show significantly lower performance following clinical recovery compared to the HC group (p = .02; d = 0.81). The mTBI, OI, and HC groups did not exhibit significant differences in working memory, explicit memory, or processing speed acutely post-injury and following clinical recovery (all p > .05; all d = 0.52 - 0.05). No significant effects of group (p = .16), time (p = .67), or the interaction (p = .45) were found on the Crystalized Cognition Composite.
Conclusions:Adolescents with mTBI demonstrated deficits on the NIHTB-CB measures of attention and executive functions acutely post-injury and extending beyond clinical recovery compared with healthy controls in this study. These subtle yet persistent deficits in cognitive performance lend support to the growing body of literature suggesting that alterations in neurotransmission may persist beyond resolution of clinical symptoms of mTBI. Further work is needed in larger samples to better understand trends in cognitive deficits and to identify clinical correlates persisting beyond clinical recovery from mTBI.

Objectives: The aim of this study was to demonstrate the utility of an evidence-based assessment (EBA) model to establish a multimodal set of tools for identifying students at risk for perceived post-injury academic problems. Methods: Participants included 142 students diagnosed with concussion (age: M=14.95; SD=1.80; 59% male), evaluated within 4 weeks of injury (median=16 days). Demographics, pre-injury history, self- and parent-report measures assessing symptom severity and executive functions, and cognitive test performance were examined as predictors of self-reported post-injury academic problems. Results: Latent class analysis categorized participants into “high” (44%) and “low” (56%) levels of self-reported academic problems. Receiver operating characteristic analyses revealed significant discriminative validity for self- and parent-reported symptom severity and executive dysfunction and self-reported exertional response for identifying students reporting low versus high academic problems. Parent-reported symptom ratings [area under the receiver operating characteristic curve (AUC)=.79] and executive dysfunction (AUC=.74), and self-reported ratings of executive dysfunction (AUC=.84), symptoms (AUC=.80), and exertional response (AUC=.70) each classified students significantly better than chance (ps<.001). Hierarchical logistic regression indicated that, of the above, self-reported symptoms and executive dysfunction accounted for the most variance in the prediction of self-reported academic problems. Conclusions: Post-concussion symptom severity and executive dysfunction significantly predict perceived post-injury academic problems. EBA modeling identified the strongest set of predictors of academic challenges, offering an important perspective in the management of concussion by applying traditional strengths of neuropsychological assessment to clinical decision making.
