研究表明，创伤后应激障碍(PTSD)与愤怒之间存在显著关系(Olatunji，Ciesielski，&Tolin，2010；Orth&Wieland，2006)。个体可能寻求紧急应对来处理愤怒的痛苦，这是一种动员和行动导向的情绪(Novaco&Chemtob，2002)；可能是与冲动与愤怒相关联的冲动行为(Milligan&Waller，2001；Whiteside&Lynam，2001)。这可能是对创伤后应激障碍和冲动之间关系的一种解释(Kotler，Julian，eFront，&Amir，2001；Ledgerwood&Peter，2006)。本研究使用性别作为冲动的协变量，评估了愤怒在PTSD(情绪/认知方面的唤醒和消极变化的总分和分量表)和冲动之间的中介作用。采用创伤后应激障碍诊断与统计手册第五版(DSM-5)、愤怒反应维度量表(DSM-5)和UPPS冲动性量表对244名有创伤史的本科生进行测试。基于1000个自举样本的结果表明，PTSD(总量表和2个分量表)对愤怒、愤怒对冲动性、PTSD(总量表和2个分量表)对冲动性有显著的直接影响。此外，愤怒显著地中介了创伤后应激障碍(总体和2个分量表)与冲动之间的关系，与假设模型一致。结果表明，冲动旨在应对令人痛苦的愤怒，这可能解释了创伤后应激障碍患者存在药物使用和其他冲动行为。此外，愤怒可能是一种动员和行动导向的情绪，伴随着创伤后应激障碍的症状。
Research indicates a significant relationship between posttraumatic stress disorder (PTSD) and anger (Olatunji, Ciesielski, & Tolin, 2010; Orth & Wieland, 2006). Individuals may seek urgent coping to deal with the distress of anger, which is a mobilizing and action-oriented emotion (Novaco & Chemtob, 2002); possibly in the form of impulsive actions consistent with impulsivity's association with anger (Milligan & Waller, 2001; Whiteside & Lynam, 2001). This could be 1 of the explanations for the relationship between PTSD and impulsivity (Kotler, Julian, Efront, & Amir, 2001; Ledgerwood & Petry, 2006). The present study assessed the mediating role of anger between PTSD (overall scores and subscales of arousal and negative alterations in mood/cognitions) and impulsivity, using gender as a covariate of impulsivity. The PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), Dimensions of Anger Reaction scale-5, and the UPPS Impulsivity Scale were administered to a sample of 244 undergraduate students with a trauma history. Results based on 1000 bootstrapped samples indicated significant direct effects of PTSD (overall and 2 subscales) on anger, of anger on impulsivity, and of PTSD (overall and 2 subscales) on impulsivity. Further, anger significantly mediated the relationship between PTSD (overall and 2 subscales) and impulsivity, consistent with the hypothesized models. Results suggest that impulsivity aims at coping with distressing anger, possibly explaining the presence of substance usage, and other impulsive behaviors in people with PTSD. Further, anger probably serves as a mobilizing and action-oriented emotion coupled with PTSD symptoms.
