Intolerance of uncertainty (IU), which can include prospective (i.e., desire for predictability) and inhibitory (i.e., uncertainty paralysis) IU, is widely understood to be a central underlying component of obsessive-compulsive disorder (OCD). IU has several treatment implications, yet research on the differences in IU underlying OCD dimensions is limited and does not account for covarying effects of overlapping symptoms, shared variance in IU, demographic variables, and comorbid psychiatric conditions like generalized anxiety disorder (GAD) and posttraumatic stress disorder (PTSD). A sample of 974 patients with diagnosed OCD enrolled in residential, partial hospitalization, and intensive outpatient treatment programs for OCD and anxiety completed self-report measures of OCD symptoms and IU at admission. Structural equation modeling included prospective. inhibitory IU, and common IU and covariates (i.e., race, ethnicity, level of care, and comorbid GAD and PTSD) as predictors of four common OCD dimensions found that contamination and unacceptable thoughts symptoms evidenced a unique relationship with IU. Specifically, whereas a common IU factor predicted all four OCD symptom dimensions, inhibitory IU uniquely predicted contamination and unacceptable thoughts symptoms over and above covarying effects. Individuals with contamination and unacceptable thoughts symptoms may be more likely to feel “paralyzed” by uncertainty due to overreliance on overt immediate rituals, outright avoidance, rumination, or difficulties with emotion regulation, and may benefit from additional psychoeducation, problem-solving, and accountability. Broadly, individuals with OCD may benefit from explicit discussions about IU-related expectancies and disconfirmation of fears.

不确定性（IU）的不宽容性可以包括预期性（即，对可预测性的期望）和抑制性（即，不确定性麻痹）IU，它被广泛认为是强迫症（OCD）的重要基础。IU具有多种治疗意义，但有关OCD尺寸基础上的IU差异的研究是有限的，并且没有考虑重叠症状，IU的共同方差，人口统计学变量以及合并症等精神疾病（如广泛性焦虑症（GAD）和创伤后疾病）的共变效应压力障碍（PTSD）。一项针对974名被诊断为强迫症的患者参加了针对强迫症和焦虑症的住院治疗，部分住院治疗和强化门诊治疗方案的样本，在入院时完成了强迫症症状和IU的自我报告测量。结构方程建模包括前瞻性。抑制性IU和常见的IU和协变量（即种族，种族，护理水平以及GAD和PTSD合并症）作为四个常见OCD维度的预测指标，发现污染和不可接受的思想症状证明与IU有独特的关系。具体而言，尽管一个常见的IU因子可以预测所有四个OCD症状的发生，但是抑制性IU可以唯一地预测污染和不可接受的思维症状，而这些变化均超过协同作用。带有污染和不可接受的思想症状的人可能由于过度依赖公开的即刻仪式，直截了当地避免，沉思或情绪调节困难而变得不确定性“瘫痪”，并且可能会受益于额外的心理教育，解决问题和问责制。宽广地，
