Multiple factor analyses have examined the dimensionality of physical, emotional, and cognitive symptoms both before and after a sport-related concussion. The current study compared model fit and measurement invariance of five candidate factor models, including a one-factor model, original four-factor model (cognitive-sensory, vestibular-somatic, sleep-arousal, and affective), alternative four-factor model (cognitive, physical, sleep-arousal, and affective), five-factor model (cognitive-sensory separated), and bifactor model.

A-12与运动有关的脑震荡前后症状的维度

多因素分析检查了运动相关脑震荡前后身体，情绪和认知症状的程度。当前的研究比较了五种候选因子模型的模型拟合和测量不变性，包括一因子模型，原始四因子模型（认知-感觉，前庭体，睡眠-情绪和情感），替代四因子模型（认知，身体，睡眠唤醒和情感），五因素模型（认知与感觉分离）和双因素模型。
