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.
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.
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.
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).
探讨心理弹性与脑震荡后症状（PCS）之间的关系，以及焦虑和抑郁症状在其中的中介作用，研究对象为脑震荡后恢复不良的儿童。
在一家儿童医院的神经心理学筛查诊所，评估了 93 名年龄在 13 至 18 岁之间的青少年。他们在就诊前 1 个月以上发生脑震荡（中位数受伤时间=5.1 个月；范围=42-473 天），且存在持续的 PCS 和认知问题的抱怨，被认为是恢复不良。使用 Connor-Davidson 韧性量表的 10 项版本测量自我报告的心理韧性；使用行为评估系统儿童版-第二版测量自我和父母报告的焦虑和抑郁症状；使用脑震荡后症状问卷测量自我和父母报告的 PCS。所有变量均同时测量。基于回归的中介分析用于检查焦虑和抑郁症状作为心理韧性与 PCS 之间关系的中介。
心理韧性显著预测了自我报告的 PCS。自我报告的焦虑和抑郁症状显著中介了韧性与自我报告的 PCS 之间的关系，父母报告的儿童抑郁症状显著中介了韧性与自我和父母报告的 PCS 之间的关系。
心理韧性在脑震荡恢复中起着重要作用，这种关系可能是通过焦虑和抑郁症状来介导的。这些结果有助于阐明心理韧性在预测有长时间症状恢复的儿童 PCS 中的作用机制。
