Objectives: Examine the mediating effects of anxiety and depressive symptoms on the relationship between psychological resilience and post-concussive symptoms (PCS) in children with poor recovery following concussion. Participants and Methods: Adolescents (N=93), ages 13 to 18 years, were assessed at a neuropsychology screening clinic at a children’s hospital. They sustained concussions more than 1 month before the clinic visit (median time since injury=5.1 months; range=42–473 days) and were seen on the basis of poor recovery (i.e., presence of persistent PCS and complaints of cognitive problems). Self-reported psychological resilience was measured using the 10-item version of the Connor-Davidson Resilience Scale; self- and parent-reported anxiety and depressive symptoms were measured using the Behaviour Assessment System for Children – Second Edition; and self- and parent-reported PCS were measured using the Post-Concussion Symptom Inventory. All variables were measured concurrently. Regression-based mediation analyses were conducted to examine anxiety and depressive symptoms as mediators of the relationship between psychological resilience and PCS. Results: Psychological resilience significantly predicted self-reported PCS. Self-reported anxiety and depressive symptoms significantly mediated the relationship between resilience and self-reported PCS, and parent-reported child depressive symptoms significantly mediated the relationship between resilience and self- and parent-reported PCS. Conclusions: Psychological resilience plays an important role in recovery from concussion, and this relationship may be mediated by anxiety and depressive symptoms. These results help shed light on the mechanisms of the role of psychological resilience in predicting PCS in children with prolonged symptom recovery. (JINS, 2019, 25, 346–354)

Objective: Concussion in children and adolescents is a prevalent problem with implications for subsequent physical, cognitive, behavioral, and psychological functioning, as well as quality of life. While these consequences warrant attention, most concussed children recover well. This study aimed to determine what pre-injury, demographic, and injury-related factors are associated with optimal outcome (“wellness”) after pediatric concussion. Method: A total of 311 children 6–18 years of age with concussion participated in a longitudinal, prospective cohort study. Pre-morbid conditions and acute injury variables, including post-concussive symptoms (PCS) and cognitive screening (Standardized Assessment of Concussion, SAC), were collected in the emergency department, and a neuropsychological assessment was performed at 4 and 12 weeks post-injury. Wellness, defined by the absence of PCS and cognitive inefficiency and the presence of good quality of life, was the main outcome. Stepwise logistic regression was performed using 19 predictor variables. Results: 41.5% and 52.2% of participants were classified as being well at 4 and 12 weeks post-injury, respectively. The final model indicated that children who were younger, who sustained sports/recreational injuries (vs. other types), who did not have a history of developmental problems, and who had better acute working memory (SAC concentration score) were significantly more likely to be well. Conclusions: Determining the variables associated with wellness after pediatric concussion has the potential to clarify which children are likely to show optimal recovery. Future work focusing on wellness and concussion should include appropriate control groups and document more extensively pre-injury and injury-related factors that could additionally contribute to wellness.

This study examined whether children's coping strategies are related to post-concussive symptoms following mild traumatic brain injury (TBI) versus orthopedic injury (OI). Participants were 8- to 15-year-old children with mild TBI (n = 167) or OI (n = 84). They rated their current preferred coping strategies and post-injury symptoms at 2 weeks (baseline) and 1, 3, and 12 months post-injury. Children's reported use of coping strategies did not vary significantly over time, so their baseline coping ratings were examined as predictors of post-concussive symptoms across time. Self-ratings of symptoms were positively related to emotion-focused strategies and negatively related to problem-focused engagement after both mild TBI and OI. Higher problem-focused disengagement predicted larger group differences in children's ratings of symptoms, suggesting that problem-focused disengagement moderates the effects of mild TBI. Coping strategies collectively accounted for approximately 10–15% of the variance in children's post-concussive symptoms over time. The findings suggest that coping may play an important role in accounting for children's perceptions of post-concussive symptoms after mild TBI. (JINS, 2011, 17, 317–326)
