This paper explored the factor structure of the PCL-5 within a sample of U.K. primary and secondary care mental health service users. Much of the previous investigations into the PCL-5 have been conducted on military or emergency service personnel; therefore, it is important to understand the validity of this tool within a broader sample. In addition to this concerns have been raised over the statistical validity of much of the previous research.
An exploratory factor analysis was used to determine the factor structure of the PCL-5 within this population.
The results of this study suggest that several items of the PCL-5 should be removed, and this presents a 3-factor structure whereby the factors are Anhedonia, Intrusion and Negative alterations in Mood and Cognition.
This challenges much of the previous literature, which suggested 4, 6, and 7 factor models. The implications of this are discussed in detail in this paper. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
本文旨在英国初级和二级精神卫生服务使用者样本中探讨 PCL-5 的因素结构。先前对 PCL-5 的许多研究都集中在军事或紧急服务人员上；因此，了解该工具在更广泛的样本中的有效性很重要。此外，人们对先前许多研究的统计有效性提出了担忧。
本研究采用探索性因素分析来确定该人群中 PCL-5 的因素结构。
本研究结果表明，PCL-5 的几项条目应被删除，呈现出 3 个因素结构，分别是快感缺失、闯入和情绪与认知的负性改变。
这与之前提出的 4、6 和 7 因素模型的大部分文献相矛盾。本文详细讨论了这一结果的意义。
