Obsessive-compulsive personality disorder (OCPD) remains understudied despite its high community prevalence and substantial societal burden. Elucidating the factors involved in OCPD traits and behaviors could improve conceptual models of OCPD and guide treatment development. Intolerance of uncertainty (IU) has been investigated as a transdiagnostic factor linked to many conditions, including anxiety disorders and obsessive-compulsive disorder (OCD). Despite OCPD's links to OCD, very little research has investigated whether IU may also be a relevant factor in OCPD. The present study administered measures of IU and OCPD to a large community sample of adults ( = 534) as well as a group of individuals with self-identified OCPD ( = 76). The OCPD measure assessed five OCPD trait dimensions as well as overall OCPD severity. We also included measures of other symptoms (OCD, depression, anxiety, and stress) as well as quality of life. Results revealed that the OCPD group reported heightened IU compared with the community sample, even when controlling for group differences in anxiety, depression, stress, and OCD symptoms. IU was significantly correlated with OCPD trait severity, and regression analyses demonstrated that IU predicted severity of OCPD traits controlling for distress symptoms. Moreover, IU significantly mediated the relationship between OCPD traits and reduced quality of life. These results highlight the importance of considering IU in the context of OCPD, with possible implications for improving treatment. Limitations and future directions for research are discussed.

强迫型人格障碍（OCPD）尽管在社区中普遍存在且对社会造成了巨大负担，但仍研究不足。阐明与 OCPD 特征和行为相关的因素可以改进 OCPD 的概念模型，并指导治疗的发展。不能容忍不确定性（IU）已被研究为与许多疾病相关的跨诊断因素，包括焦虑症和强迫症（OCD）。尽管 OCPD 与 OCD 有关，但很少有研究调查 IU 是否也是 OCPD 的一个相关因素。本研究向一个大型社区成年人样本（n=534）以及一组自我报告患有 OCPD 的个体（n=76）发放了 IU 和 OCPD 的测量工具。OCPD 量表评估了五个 OCPD 特征维度以及整体 OCPD 严重程度。我们还包括了其他症状（OCD、抑郁、焦虑和压力）以及生活质量的测量。结果表明，即使在控制焦虑、抑郁、压力和 OCD 症状的组间差异后，OCPD 组报告的 IU 也明显高于社区样本。IU 与 OCPD 特征严重程度显著相关，回归分析表明，IU 可以预测控制痛苦症状后的 OCPD 特征严重程度。此外，IU 显著中介了 OCPD 特征与生活质量下降之间的关系。这些结果强调了在 OCPD 背景下考虑 IU 的重要性，这可能对改善治疗有影响。讨论了研究的局限性和未来方向。
