Despite an abundance of evidence linking maltreatment and violence-related trauma exposure to externalizing problems in youth, there is surprisingly little evidence to support a direct link between disaster exposure and youth aggressive behavior. This study tested the theory that there is primarily an indirect association between disaster exposure and aggression via posttraumatic stress disorder (PTSD) symptoms. The current study also examined the association between aggression and academic achievement. A sample of 191 4th- to 8th-grade minority youth who experienced Hurricane Katrina were assessed for aggressive behavior using the Peer Conflict Scale (PCS), disaster exposure, PTSD symptoms, and academic achievement. Structural equation modeling of the set of associations was consistent with the theory suggesting that there is an indirect link between disaster exposure and aggression through PTSD symptoms. Aggression was negatively associated with academic achievement, and modeling indicated that the set of associations was age and gender invariant. Findings advance the theoretical understanding of the linkage between aggression and disaster exposure. Findings also support the utility of the PCS in disaster research and the link between PCS scores and academic achievement.
尽管有大量证据表明虐待和与暴力相关的创伤暴露与青少年的外化问题有关，但令人惊讶的是，几乎没有证据支持灾难暴露与青少年攻击行为之间存在直接联系。本研究检验了这样一种理论，即灾难暴露与攻击行为之间主要是通过创伤后应激障碍（PTSD）症状存在间接关联。本研究还考察了攻击行为与学业成绩之间的关联。使用同伴冲突量表（PCS）、灾难暴露、PTSD症状和学业成绩，对191名经历过卡特里娜飓风的四至八年级少数族裔青少年样本的攻击行为进行了评估。对这组关联进行的结构方程建模与该理论一致，表明灾难暴露与攻击行为之间通过PTSD症状存在间接联系。攻击行为与学业成绩呈负相关，建模表明这组关联在年龄和性别上具有不变性。研究结果推进了对攻击行为与灾难暴露之间联系的理论理解。研究结果还支持了PCS在灾难研究中的效用以及PCS分数与学业成绩之间的联系。
