The cognitive perspective on post-traumatic stress disorder (PTSD) has been successful in explaining many PTSD-related phenomena and in developing effective treatments, yet some of its basic assumptions remain surprisingly under-examined. The present study tested two of these assumptions: (1) situational appraisals of the event as violating global meaning (i.e., beliefs and goals) is related to PTSD symptomatology, and (2) the effect of situational appraisals of violation on PTSD symptomatology is mediated by global meaning (i.e., views of self and world). We tested these assumptions in a cross-sectional study of 130 college students who had experienced a DSM-IV level trauma. Structural equation modeling showed that appraisals of the extent to which the trauma violated one's beliefs and goals related fairly strongly to PTSD. In addition, the effects of appraisals of belief and goal violations on PTSD symptoms were fully mediated through negative global beliefs about both the self and the world. These findings support the cognitive worldview perspective, highlighting the importance of the meaning individuals assign to traumatic events, particularly the role of meaning violation.
创伤后应激障碍(PTSD)的认知视角在解释许多与PTSD相关的现象以及开发有效治疗方法方面取得了成功,但它的一些基本假设仍令人惊讶地未得到充分检验。本研究对其中两个假设进行了检验:(1)将事件情境评估为违反全局意义(即信念和目标)与PTSD症状学相关,以及(2)违反情境评估对PTSD症状学的影响是由全局意义(即自我和世界的看法)介导的。我们在一项对130名经历过DSM-IV级创伤的大学生的横断面研究中检验了这些假设。结构方程模型表明,对创伤违反个人信念和目标程度的评估与PTSD有相当强的关联。此外,对信念和目标违反的评估对PTSD症状的影响完全通过对自我和世界的负面全局信念介导。这些发现支持了认知世界观视角,突出了个体赋予创伤事件的意义的重要性,特别是意义违反的作用。
