本研究旨在探讨创伤后认知量表（PTCI; E。B。Foa，A. Ehlers，D. M.克拉克，D. F. Tolin，& S. M. Orsillo，1999年）在112名经历过严重机动车事故的人的样本中。结果基本支持PTCI的三因素结构：（a）关于自我的消极认知，（B）关于世界的消极认知，（c）自我责备。反映自我和世界的消极思想的分量表显示出足够的内部一致性，以及良好的并发，判别和区分效度。然而，代表自责的分量表出现了困难，特别是并发和判别效度差。这一发现的潜在原因进行了讨论。PTCI似乎是一个很有前途的措施，创伤后的负面和功能失调的认知，值得继续关注。
This study examined the factor structure, internal consistency, concurrent validity, discriminant validity, and discriminative validity of the Posttraumatic Cognitions Inventory (PTCI; E. B. Foa, A. Ehlers, D. M. Clark, D. F. Tolin, & S. M. Orsillo, 1999) in a sample of 112 individuals who had experienced a serious motor vehicle accident. Results generally supported the 3-factor structure of the PTCI: (a) Negative Cognitions About Self, (b) Negative Cognitions About the World, and (c) Self-Blame. Subscales reflecting negative thoughts of the self and world showed adequate internal consistency, as well as good concurrent, discriminant, and discriminative validity. However, difficulties with the subscale representing self-blame emerged, specifically poor concurrent and discriminant validity. Potential reasons for this finding are discussed. The PTCI seems to be a promising measure of negative and dysfunctional posttrauma cognitions, which deserves continuing attention.
