本文介绍了一种新的创伤相关思想和信念测量方法——创伤后认知量表（PTCI）的开发和验证，其项目源自临床观察和当前创伤后精神病理学理论。 PTCI 接受了 601 名志愿者的治疗，其中 392 人经历过创伤事件，其中 170 人患有中度至重度创伤后应激障碍 (PTSD)。主成分分析得出 3 个因子：关于自我的负面认知、关于世界的负面认知和自责。 3个因素表现出良好的内部一致性和良好的重测信度；与 PTSD 严重程度、抑郁和一般焦虑的测量结果存在中度至强相关性；并能很好地区分患有和不患有创伤后应激障碍 (PTSD) 的创伤个体。 PTCI 与其他创伤相关认知测量相比具有优势，特别是它区分患有和不患有 PTSD 的创伤个体的卓越能力。
This article describes the development and validation of a new measure of trauma-related thoughts and beliefs, the Posttraumatic Cognitions Inventory (PTCI), whose items were derived from clinical observations and current theories of post-trauma psychopathology. The PTCI was administered to 601 volunteers, 392 of whom had experienced a traumatic event and 170 of whom had moderate to severe posttraumatic stress disorder (PTSD). Principal-components analysis yielded 3 factors: Negative Cognitions About Self, Negative Cognitions About the World, and Self-Blame. The 3 factors showed excellent internal consistency and good test-retest reliability; correlated moderately to strongly with measures of PTSD severity, depression, and general anxiety; and discriminated well between traumatized individuals with and without PTSD. The PTCI compared favorably with other measures of trauma-related cognitions, especially in its superior ability to discriminate between traumatized individuals with and without PTSD.
