Verbal fluency is a neuropsychological measure commonly used to examine cognitive-linguistic performance as reported in pediatric TBI literature. We synthesized the scholarly literature of verbal fluency performance in pediatric TBI and estimated the effects of TBI according to: (i) type of verbal fluency task (phonemic or semantic), (ii) severity of TBI, and (iii) time post-injury. Meta-analysis revealed that childhood TBI negatively impacted phonemic fluency and semantic fluency and that effect sizes were larger for children with more severe TBI. The negative effect of TBI was evident across time post injury within each level of severity. Verbal fluency tasks are efficient indicators of potential underlying impairments in lexical knowledge and executive functioning in children with TBI regardless of severity of injury or time post injury. Future research employing verbal fluency tasks are encouraged to explore if age at injury differentiates semantic versus phonemic fluency outcomes across severity levels.
言语流畅性是一种神经心理学测量方法，常用于检查儿科创伤性脑损伤文献中报告的认知语言表现。我们综合了儿科创伤性脑损伤言语流畅性表现的学术文献，并根据以下因素估计创伤性脑损伤的影响：（i）言语流畅性任务的类型（语音或语义），（ii）创伤性脑损伤的严重程度，以及（iii）损伤后时间。荟萃分析表明，儿童创伤性脑损伤对语音流畅性和语义流畅性产生负面影响，且严重程度较高的儿童的效应大小更大。在每个严重程度水平内，损伤后时间的推移都显示出创伤性脑损伤的负面影响。言语流畅性任务是儿童创伤性脑损伤者词汇知识和执行功能潜在损伤的有效指标，无论损伤严重程度或损伤后时间如何。鼓励未来使用言语流畅性任务的研究，以探索损伤时的年龄是否会在严重程度水平上区分语义流畅性和语音流畅性的结果。
