目的：本研究旨在确定19项脑震荡后症状量表的因子结构，并研究因子评分与性别、既往脑震荡史和受伤时间长短之间的关系。研究方法：这是一项对2008年4月至2012年9月在运动医学诊所就诊的脑震荡儿科患者的回顾性病历审查。我们进行了探索性因素分析（EFA），然后进行验证性因素分析（CFA）。方差分析和回归分析被用来检查因素得分和性别之间的关联，以前的历史，脑震荡，情绪障碍，焦虑症或注意力缺陷障碍，以及受伤后的时间长度。结果：EFA支持采用18个原始的19个量表项目的脑震荡后症状的三因素解决方案。因子1包括8个认知相关的项目，因子2包括6个躯体相关的项目，因子3包括4个情感相关的项目。CFA结果证实了因素1（神经认知），2（躯体）和3（情感）的单维度，与因素3被认为是边界。女性和焦虑症患者在所有三个因素上的得分都显着更差（更高）。脑震荡损伤后>14天的患者比脑震荡损伤后14天的患者有更差（更高）的因子3（情绪）评分，情绪症状评分更高，这表明长时间的脑震荡症状可能会影响情绪健康。
Purpose: This study aimed to determine the factor structure of a 19-item Postconcussion Symptom Scale and to examine associations between factor scores and sex, previous history of concussion, and length of time since injury. Methods: This is a retrospective medical record review of pediatric patients with concussion seen in a sports medicine clinic from April 2008 to September 2012. We performed an exploratory factor analysis (EFA) followed by a confirmatory factor analysis (CFA). ANOVA and regression analysis were used to examine associations between factor scores and sex, previous history of concussion, mood disorder, anxiety disorder or attention-deficit disorder, and length of time since injury. Results: EFA supported a three-factor solution for postconcussive symptoms employing 18 of the original 19 scale items. Factor 1 consisted of eight cognition-related items, factor 2 consisted of six somatic-related items, and factor 3 consisted of four emotional-related items. CFA results confirmed the unidimensionality of factors 1 (neurocognitive), 2 (somatic) and 3 (emotional), with factor 3 being considered borderline. Females and patients with anxiety disorders had significantly worse (higher) scores on all three factors. Patients seen >14 d after the concussive injury had worse (higher) factor 3 (emotional) scores than those seen 14 d after concussive injury had higher scores for emotional symptoms, suggesting that prolonged concussion symptoms may affect emotional health.
