BACKGROUND AND OBJECTIVES
The degree to which a traumatic event is seen as central to one's sense of self (trauma centrality) has been associated with posttraumatic stress disorder (PTSD) symptoms. Based on cognitive models of PTSD that highlight the role that maladaptive appraisals play in generating PTSD symptoms, we hypothesized that appraising a trauma as violating one's core beliefs and goals mediates the link between trauma centrality and PTSD symptoms. Further, we reasoned that coping ability moderates the direct and indirect link as those with better coping ability will have more adaptive appraisals.
DESIGN
Hypotheses were examined in a cross-sectional sample of 367 undergraduates who have experienced a traumatic event.
METHODS
Data were collected via an online survey.
RESULTS
Overall, results of the moderated mediation analysis were consistent with the hypothesized mediating role for appraised violations and moderating role for coping ability.
CONCLUSIONS
Findings highlight the importance of considering individual differences and trauma appraisals in understanding the relationship between trauma centrality and PTSD - trauma centrality may be related to PTSD symptoms more so among people with poorer coping ability who appraise a trauma as violating their core beliefs and goals.
背景与目的
创伤事件被视为对自我认知至关重要的程度（创伤核心性）与创伤后应激障碍（PTSD）症状相关。基于强调适应不良评估在产生PTSD症状中所起作用的PTSD认知模型，我们假设将创伤评估为违反个人核心信念和目标会介导创伤核心性与PTSD症状之间的联系。此外，我们推断应对能力会调节直接和间接联系，因为应对能力较强的人会有更具适应性的评估。
设计
在367名经历过创伤事件的本科生横断面样本中检验假设。
方法
通过在线调查收集数据。
结果
总体而言，有调节的中介分析结果与评估的违规行为的假设中介作用以及应对能力的调节作用一致。
结论
研究结果凸显了在理解创伤核心性与PTSD之间的关系时考虑个体差异和创伤评估的重要性——在应对能力较差且将创伤评估为违反其核心信念和目标的人群中，创伤核心性可能与PTSD症状的关联更为密切。
