Increasing evidence suggests that intolerance of uncertainty (IU) may be a transdiagnostic factor across the anxiety disorders, and to a lesser extent, unipolar depression. Whereas anxiety inherently involves uncertainty regarding threat, depression has traditionally been associated with certainty (e.g. the hopelessness theory of depression). Some theorists posit that the observed relationship between depression and IU may be due to the relationship between depression and anxiety and the relationship between anxiety and IU. The present study sought to elucidate the unique relationships among trait anxiety, depression, and IU in undergraduate (N = 554) and clinical (generalized anxiety disorder; N = 43) samples. Findings suggest that IU may play a larger role in anxiety than depression, although some evidence indicates that inhibitory IU and depression may have a modest but independent relationship.
越来越多的证据表明，对不确定性的不耐受（IU）可能是焦虑症的一个跨诊断因素，在较小程度上也是单相抑郁症的跨诊断因素。虽然焦虑本质上涉及对威胁的不确定性，但传统上抑郁症与确定性相关（例如抑郁症的绝望理论）。一些理论家认为，观察到的抑郁症与IU之间的关系可能是由于抑郁症与焦虑症之间的关系以及焦虑症与IU之间的关系。本研究旨在阐明本科样本（N = 554）和临床样本（广泛性焦虑症；N = 43）中特质焦虑、抑郁症和IU之间的独特关系。研究结果表明，IU在焦虑症中可能比在抑郁症中起更大作用，尽管一些证据表明抑制性IU与抑郁症可能存在适度但独立的关系。
