This study examined the relationship between postconcussion-like symptoms and depressive symptoms, anxiety and stress respectively. Seventy-one university students with a negative concussion history completed the Depression Anxiety Stress Scales (DASS) and the British Columbia Postconcussion Symptom Inventory (BC-PSI). A multiple regression was conducted using the three DASS subscale scores as predictors of postconcussion-like symptoms. Depressive symptoms, anxiety and stress were significantly positively correlated with postconcussion-like symptoms at the bivariate level. When these three factors were examined together 72.9% of variance in BC-PSI total scores was explained overall. Stress and depressive symptoms emerged as significant multivariate predictors explaining 15% and 3% of unique variance, respectively. Anxiety was not a significant multivariate predictor. These results suggest that stress may be a more important predictor of postconcussion-like symptoms than previously identified. Findings are interpreted in light of Iverson (2012) conceptual model of poor outcomes from mild traumatic brain injury.
本研究考察了脑震荡后样症状与抑郁症状、焦虑和压力之间的关系。71 名无脑震荡史的大学生完成了抑郁焦虑压力量表（DASS）和不列颠哥伦比亚省脑震荡后症状清单（BC-PSI）。采用多元回归分析，以三个 DASS 分量表的分数作为脑震荡后样症状的预测因子。在双变量水平上，抑郁症状、焦虑和压力与脑震荡后样症状显著正相关。当同时考察这三个因素时，BC-PSI 总分的 72.9%的方差得到了解释。压力和抑郁症状作为显著的多变量预测因子，分别解释了 15%和 3%的独特方差。焦虑不是一个显著的多变量预测因子。这些结果表明，与之前确定的因素相比，压力可能是脑震荡后样症状的一个更重要的预测因子。研究结果根据 Iverson（2012）的轻度创伤性脑损伤不良预后的概念模型进行了解释。
