Stability is thought to be one of the major distinguishing features between personality disorders (PDs) and other forms of psychopathology. The development of more reliable PD assessments and the implementation of four major longitudinal studies on PD stability have provided critical data with which to evaluate the stability of PD features. Results from these and other studies reveal significant complexity in the interpretation of PD stability because of several issues that can impact stability estimates. Such estimates will vary as a function of the type of constructs being assessed, the type of stability being considered, the modality and reliability of the assessments being used, and the impacts of sampling. In this article, longitudinal research on PD stability is reviewed in the context of these issues. It is concluded that no single answer can be given to the question, "How stable are PDs?" and that future research and classification need to consider carefully and account for the complexity of this question.
稳定性被认为是人格障碍（PD）和其他形式的精神病理学之间的主要区别特征之一。开发更可靠的 PD 评估方法和实施四项关于 PD 稳定性的主要纵向研究提供了关键数据，可用于评估 PD 特征的稳定性。这些研究和其他研究的结果揭示了 PD 稳定性解释的显著复杂性，因为有几个问题会影响稳定性估计。这些估计会因所评估的构念类型、所考虑的稳定性类型、所使用的评估方式和可靠性以及抽样的影响而有所不同。本文在这些问题的背景下回顾了 PD 稳定性的纵向研究。结论是，对于“PD 有多稳定？”这个问题，不能给出一个单一的答案，未来的研究和分类需要仔细考虑并考虑到这个问题的复杂性。
