Abstract

The Posttraumatic Cognitions Inventory (PTCI) is a widely used self-report tool to assess negative posttraumatic cognitions about self, world, and self-blame, but the factor structure remains controversial. Recently, a brief version of the PTCI with nine items (PTCI-9) loading onto three factors has been developed, and an excellent model fit was obtained. In this study, we examined the psychometric properties of the PTCI and PTCI-9 in a large sample of trauma-exposed Chinese adolescents (n = 1,451; mean age = 13.67 years, SD = 1.24) and adults (n = 924; mean age = 39.6 years, SD = 5.43). Confirmatory factor analysis indicated an acceptable model fit for the original PTCI but a better model fit for the PTCI-9. Furthermore, the configural, metric, and scalar invariances of the PTCI-9 were supported across age groups (adolescent and adult), gender (male and female), trauma exposure (direct and indirect), and types of traumatic events (interpersonal and noninterpersonal). The PTCI and PTCI-9 and their subscale scores showed adequate internal consistency reliability in adolescent and adult samples. The PTCI-9 also demonstrated good convergent validity, as demonstrated by statistically significant correlations with PTSD, depression, anxiety, and life satisfaction. Overall, the present study supports the Chinese PTCI and PTCI-9 as valid measures of negative cognitions in both adolescents and adults and makes meaningful comparisons of negative cognitions across gender, trauma exposure, and types of traumatic events. Notably, as a brief and valid tool, the PTCI-9 is suggested to be used in survey and longitudinal studies for adolescents and adults. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

中国青少年和成人创伤后认知量表(PTCI)及其简明版(PTCI-9)的因子结构、测量不变性和心理测量学特性。
创伤后认知量表(PTCI)是一种广泛使用的自我报告工具,用于评估创伤后对自我、世界和自责的负面认知,但其因子结构仍存在争议。最近,一个包含九个项目的简短版 PTCI(PTCI-9)被开发出来,它包含三个因子,并获得了极佳的模型拟合效果。在本研究中,我们以大量受过创伤的中国青少年(n = 1,451;平均年龄 = 13.67 岁,SD = 1.24)和成人(n = 924;平均年龄 = 39.6 岁,SD = 5.43)为样本,检验了 PTCI 和 PTCI-9 的心理计量特性。确认性因素分析表明,原始 PTCI 的模型拟合度可以接受,但 PTCI-9 的模型拟合度更高。此外,PTCI-9 在不同年龄组(青少年和成人)、性别(男性和女性)、创伤暴露(直接和间接)以及创伤事件类型(人际和非人际)之间的构型、度量和标度不变量都得到了支持。在青少年和成人样本中,PTCI 和 PTCI-9 及其子量表得分显示出足够的内部一致性可靠性。PTCI-9 与创伤后应激障碍、抑郁、焦虑和生活满意度之间的相关性在统计学上具有显著意义,这也证明了 PTCI-9 具有良好的收敛效度。总之,本研究支持中文 PTCI 和 PTCI-9 作为青少年和成人负性认知的有效测量工具,并对不同性别、创伤暴露和创伤事件类型的负性认知进行了有意义的比较。值得注意的是,作为一种简短有效的工具,PTCI-9 建议用于青少年和成人的调查和纵向研究。(PsycInfo Database Record (c) 2024 APA,保留所有权利)。

期刊介绍: Psychological Assessment is concerned mainly with empirical research on measurement and evaluation relevant to the broad field of clinical psychology. Submissions are welcome in the areas of assessment processes and methods. Included are - clinical judgment and the application of decision-making models - paradigms derived from basic psychological research in cognition, personality–social psychology, and biological psychology - development, validation, and application of assessment instruments, observational methods, and interviews
