Research suggests a relationship between intolerance of uncertainty (IU) and obsessive-compulsive disorder (OCD), though this has been limited to self-report measures of OCD symptoms. The current investigation examined the relationship between IU and multiple symptom domains of OCD using self-report and in vivo assessments of OC symptoms.
Five separate studies are presented in which undergraduate students (N=603) were administered a self-report measure of IU and tasks related to either ordering and arranging, checking, washing, contamination avoidance, or neutralization.
Intolerance of uncertainty was found to be significantly related to each self-report measure of the OCD symptom domains (ps < .01). Further, IU was predictive of performance on all in vivo tasks (ps < .05) except one concerning neutralizing/harm-related obsessions.
This study relied on an unselected sample and was correlational in design.
The current study demonstrates that IU is related to multiple OC symptom dimensions. Future experimental research is warranted to evaluate the causal role of IU in OCD.
研究表明，无法容忍不确定性（IU）与强迫症（OCD）之间存在关联，尽管这仅限于 OCD 症状的自我报告测量。本研究使用 OC 症状的自我报告和现场评估，考察了 IU 与 OCD 的多个症状领域之间的关系。
本研究共包括五项独立研究，其中招募了 603 名本科生，对他们进行了 IU 的自我报告测量，以及与排序和整理、检查、洗涤、避免污染或中和相关的任务。
无法容忍不确定性与 OCD 症状领域的每个自我报告测量都显著相关（p<.01）。此外，IU 可预测所有现场任务的表现（p<.05），除了一个与中和/与伤害相关的强迫观念相关的任务。
本研究依赖于非选择性样本，且设计为相关性研究。
本研究表明，IU 与多个 OC 症状维度相关。未来需要进行实验研究，以评估 IU 在 OCD 中的因果作用。
