对186例8~15岁轻度颅脑损伤(TBI)儿童进行了前瞻性纵向研究，考察了脑震荡后症状(PCS)的维度。父母和孩子在受伤后2周内完成50个项目的问卷调查，并在受伤后3个月再次完成问卷调查，对PCS的频率进行4分制的评分。使用目标轮换的公共因素分析将评分旋转到代表认知、躯体、情绪和行为症状的四个假设维度。基准家长评分的旋转因子矩阵与目标矩阵一致。儿童基线评分的旋转矩阵与认知和躯体症状的目标矩阵一致，但情绪和行为症状的目标矩阵不一致。损伤后3个月获得的旋转评分矩阵与基线评分分析得出的目标矩阵基本一致，只是行为症状的父母评分没有像以前那样聚集在一起。轻度脑损伤后的父母和孩子对PCS的评级产生了反映认知和躯体症状维度的一致因素，但情绪和行为症状的维度在时间和评分者之间不那么稳健。
The dimensions of postconcussive symptoms (PCS) were examined in a prospective, longitudinal study of 186 8 to 15 year old children with mild traumatic brain injuries (TBI). Parents and children completed a 50-item questionnaire within 2 weeks of injury and again at 3 months after injury, rating the frequency of PCS on a 4-point scale. Common factor analysis with target rotation was used to rotate the ratings to four hypothesized dimensions, representing cognitive, somatic, emotional, and behavioral symptoms. The rotated factor matrix for baseline parent ratings was consistent with the target matrix. The rotated matrix for baseline child ratings was consistent with the target matrix for cognitive and somatic symptoms but not for emotional and behavioral symptoms. The rotated matrices for ratings obtained 3 months after injury were largely consistent with the target matrix derived from analyses of baseline ratings, except that parent ratings of behavioral symptoms did not cluster as before. Parent and child ratings of PCS following mild TBI yield consistent factors reflecting cognitive and somatic symptom dimensions, but dimensions of emotional and behavioral symptoms are less robust across time and raters.
