在这项研究中，我们检查了33项创伤后认知量表（Foa，Ehlers，Clark，Tolin，& Orsillo，1999）在213名事故相关创伤和190名人际创伤患者中的心理测量学特性。在剔除4个冗余项目后，验证性因素分析基本支持量表的原始三因素结构：关于自我的消极认知（SELF）、关于世界的消极认知（WORLD）和自我责备（BLAME）。然而，与以前的研究结果一致，BLAME的结果仍然是不确定的，因为该量表在事故相关创伤的个体中表现不佳，而与人际创伤的拟合是可以接受的。责备可能与创伤类型有关。我们的研究结果表明，拟议的29项版本显示出可接受的心理测量特性和BLAME的作用，应进一步研究。
In this study, we examined the psychometric properties of the 33-item Posttraumatic Cognitions Inventory (Foa, Ehlers, Clark, Tolin, & Orsillo, 1999) in 213 individuals with accident-related trauma and 190 individuals with interpersonal trauma. Confirmatory factor analyses generally supported the scale's original three-factor structure Negative Cognitions About Self (SELF), Negative Cognitions About World (WORLD), and Self-Blame (BLAME) after four redundant items were excluded. However, in line with previous findings, results for BLAME remained inconclusive because the scale performed poorly with the individuals with accident-related trauma, whereas its fit with those with interpersonal trauma was acceptable. BLAME might possibly relate to trauma type. Our results indicate that the proposed 29-item version shows acceptable psychometric properties and that the role of BLAME should be further investigated.
