Background:

Researchers have examined intolerance of uncertainty (IU) and negative beliefs about worry (NBW) in emotional disorders. However, the distinct relationships of IU and NBW remain unclear. We examined IU and NBW across emotional disorders, controlling for overlapping symptoms. We also explored prospective and inhibitory IU.

Methods:

A sample of 565 undergraduates completed measures of IU and NBW, as well as measures of generalized anxiety, depression, social anxiety, panic, post-traumatic stress, obsessive-compulsive, and illness anxiety disorder symptoms. Regression analyses were used to determine which factors were uniquely associated with symptoms of each disorder.

Results:

Both IU and NBW were associated with generalized anxiety and social anxiety disorder symptoms. IU was also associated with obsessive-compulsive disorder symptoms and negatively associated with panic disorder symptoms. NBW was also associated with depression. Neither IU now NBW were associated with post-traumatic stress or illness anxiety disorders. Prospective and inhibitory IU also had differential associations with the emotional disorders.

Conclusions:

Our results indicate that IU and NBW, while transdiagnostic, are differentially associated with emotional disorder symptoms. Our results also support the discriminant validity of prospective and inhibitory IU.

区分不确定的不宽容和对情绪障碍的担忧的负面信念的作用

背景：

研究人员检查了情绪障碍中不确定性的不宽容（IU）和对忧虑的消极信念（NBW）。但是，IU和NBW的不同关系仍不清楚。我们检查了情绪障碍之间的IU和NBW，以控制重叠症状。我们还探讨了前瞻性和抑制性IU。

方法：

565名大学生的样本完成了IU和NBW的测量，以及广泛性焦虑，抑郁，社交焦虑，恐慌，创伤后压力，强迫症和疾病焦虑症症状的测量。回归分析用于确定哪些因素与每种疾病的症状独特相关。

结果：

IU和NBW均与广泛性焦虑和社交焦虑症症状相关。IU还与强迫症症状相关，而与惊恐障碍症状负相关。NBW也与抑郁有关。IU现在的NBW均与创伤后压力或疾病焦虑症无关。前瞻性和抑制性IU也与情绪障碍有不同的关联。

结论：

我们的研究结果表明，IU和NBW虽然具有诊断性，但与情绪障碍症状存在差异。我们的结果也支持前瞻性和抑制性IU的判别有效性。
