Distress intolerance is an important transdiagnostic variable that has long been implicated in the development and maintenance of psychological disorders. Self-report measurement strategies for distress intolerance (DI) have emerged from several different models of psychopathology and these measures have been applied inconsistently in the literature in the absence of a clear gold standard. The absence of a consistent assessment strategy has limited the ability to compare across studies and samples, thus hampering the advancement of this research agenda. This study evaluated the latent factor structure of existing measures of DI to examine the degree to which they are capturing the same construct. Results of confirmatory factor analysis in three samples totaling 400 participants provided support for a single-factor latent structure. Individual items of these four scales were then correlated with this factor to identify those that best capture the core construct. Results provided consistent support for 10 items that demonstrated the strongest concordance with this factor. The use of these 10 items as a unifying measure in the study of DI and future directions for the evaluation of its utility are discussed.
痛苦不耐受是一个重要的跨诊断变量，长期以来一直与心理障碍的发展和维持有关。痛苦不耐受 (DI) 的自我报告测量策略源于几种不同的精神病理学模型，这些测量方法在文献中应用不一致，缺乏明确的金标准。缺乏一致的评估策略限制了跨研究和样本进行比较的能力，从而阻碍了这一研究议程的推进。本研究评估了现有 DI 测量方法的潜在因素结构，以检验它们在多大程度上捕捉到相同的结构。在三个样本中进行的验证性因素分析的结果为单因素潜在结构提供了支持，这三个样本共有 400 名参与者。然后，将这四个量表的个别项目与该因素相关联，以确定最能捕捉核心结构的项目。结果一致支持 10 个项目，这些项目与该因素具有最强的一致性。讨论了在 DI 研究中使用这 10 个项目作为统一测量方法以及评估其效用的未来方向。
