Abstract

Objectives

Intolerance of uncertainty (IU) is a cognitive vulnerability factor that plays a role in obsessive compulsive disorder (OCD). Most research has looked at IU at an omnibus level. This paper aimed to investigate the two dimensions of IU, prospective and inhibitory IU, and their relation to overall OCD symptom severity, as well as the severity of obsessions and compulsions. Method: Fifty-nine individuals with OCD completed measures of OCD symptom severity and IU at pre- and post- group cognitive behavioral therapy (CBT).

Results

IU and OCD symptoms, and their dimensions, all reduced over the CBT treatment. At the start of treatment, only prospective IU was associated with compulsion symptom severity. In contrast, at the end of treatment, prospective and inhibitory IU were associated with compulsion symptom severity, and inhibitory IU was associated with obsession symptom severity. Baseline IU, prospective and inhibitory IU were not associated with post OCD symptom severity scores, when controlling for pre-treatment OCD severity levels. Change in prospective IU was associated with changes in OCD symptom severity, and change in compulsions, but not change in obsessions. The results cannot speak to causal or temporal predictions, or directionality of the relationship between IU and OCD.

Conclusion

These findings underscore the dynamic relationship between the IU dimensions and OCD symptoms, and highlights prospective IU as a potential important target in CBT for OCD to achieve reductions in compulsions and overall OCD symptom severity.

探讨前瞻性和抑制性不确定性耐受、强迫症症状和治疗结果之间的关系。

目的：不确定性不耐受（IU）是强迫症（OCD）的一种认知易感性因素。大多数研究都是在综合水平上研究IU的。本研究旨在探讨预期IU和抑制性IU两个维度，以及它们与强迫症整体症状严重程度、强迫和强迫严重程度的关系。方法：59例强迫症患者在组前和组后认知行为治疗（CBT）中完成强迫症症状严重程度和IU的测量。结果：与CBT治疗相比，IU和OCD症状及其维度均有所降低。在治疗开始时，只有预期IU与强迫症状严重程度相关。相比之下，治疗结束时，前瞻性IU和抑制性IU与强迫症状严重程度相关，抑制性IU与强迫症状严重程度相关。在控制治疗前强迫症严重程度水平时，基线IU、前瞻性IU和抑制性IU与强迫症后症状严重程度评分无关。预期IU的改变与强迫症症状严重程度的改变和强迫行为的改变有关，但与强迫行为的改变无关。结果不能说明因果关系或时间预测，或IU与强迫症之间关系的方向性。结论：这些发现强调了IU维度与强迫症症状之间的动态关系，并强调了未来IU是强迫症CBT治疗中实现强迫和整体强迫症症状严重程度降低的潜在重要目标。
