Pediatric mild traumatic brain injury (pmTBI) has received increased public scrutiny over the past decade, especially regarding children who experience persistent post-concussive symptoms (PPCS). However, several methods for defining PPCS exist in clinical and scientific literature, and even healthy children frequently exhibit non-specific, concussive-like symptoms. Inter-method agreement (six PPCS methods), observed misclassification rates, and other psychometric properties were examined in large cohorts of consecutively recruited adolescent patients with pmTBI (n = 162) 1 week and 4 months post-injury and in age/sex-matched healthy controls (HC; n = 117) at equivalent time intervals. Six published PPCS methods were stratified into Simple Change (e.g., International Statistical Classification of Diseases and Related Health Problems, 10th revision [ICD-10]) and Standardized Change (e.g., reliable change indices) algorithms.

儿童持续性脑震荡后症状分类方法的比较。


在过去的十年里，小儿轻度创伤性脑损伤 (pmTBI) 受到了越来越多的公众关注，特别是对于经历持续性脑震荡后症状 (PPCS) 的儿童。然而，临床和科学文献中存在多种定义 PPCS 的方法，甚至健康儿童也经常表现出非特异性的脑震荡样症状。在损伤后 1 周和 4 个月且年龄/性别匹配的连续招募的 PMTBI 青少年患者 ( n = 162) 的大队列中，检查了方法间一致性（六种 PPCS 方法）、观察到的错误分类率和其他心理测量特性以相同的时间间隔进行健康对照（HC； n = 117）。六种已发表的 PPCS 方法被分为简单变化（例如，国际疾病和相关健康问题统计分类，第 10 次修订版 [ICD-10]）和标准变化（例如，可靠变化指数）算法。
