对不确定性的不耐受（IU）已被确定为广泛性焦虑障碍的潜在维持因素;然而，越来越多的证据表明IU可能导致其他焦虑和抑郁障碍。此外，IU的某些成分（即前瞻性和抑制性IU）已被证明与情绪障碍的症状有差异。本研究的目的是确定在何种程度上个人与各种焦虑和抑郁障碍认可IU，首先作为一个特质变量（与前瞻性和抑制成分），其次在参考定期发生的，诊断相关的情况下（具体情况IU）。在高度共病的临床样本（N = 218）中检查了诊断预测IU的程度。无论具体诊断如何，合并症的程度都是前瞻性IU和特定情况IU的重要预测因素。相反，社交恐惧症、广泛性焦虑症、抑郁症和强迫症的具体诊断与抑制性IU唯一相关。这些研究结果表明，IU是一个transdiagnosis结构，并对目前的诊断特异性和transdiagnosis理论和临床实践的影响。
Intolerance of uncertainty (IU) has been identified as a potential maintaining factor for generalised anxiety disorder; however, there is a growing evidence to suggest that IU may contribute to other anxiety and depressive disorders. Moreover, certain components of IU (namely prospective and inhibitory IU) have been shown to be differentially associated with symptoms of emotional disorders. The aim of this study was to determine the extent to which individuals with various anxiety and depressive disorders endorsed IU, firstly as a trait variable (with prospective and inhibitory components) and secondly in reference to regularly occurring, diagnostically relevant situations (situation-specific IU). The degree to which diagnosis predicted IU was examined in a highly comorbid clinical sample (N = 218). Regardless of specific diagnoses, the degree of comorbidity emerged as a significant predictor of prospective IU and situation-specific IU. Conversely, specific diagnoses of social phobia, generalised anxiety disorder, depression, and obsessive compulsive disorder were uniquely related to inhibitory IU. These findings suggest that IU is a transdiagnostic construct and have implications for current diagnosis-specific and transdiagnostic theory and clinical practice.
