The construct of discomfort intolerance (proposed as an individual difference in the ability to tolerate uncomfortable sensations) is introduced and psychometric properties of a measure of this trait are provided. The Discomfort Intolerance Scale (DIS), a self-report measure of discomfort intolerance, was evaluated using a variety of samples (total N approximately 1700), including patients with panic disorder, clinical controls, and nonclinical community members. Factor analyses suggest the DIS contains two factors, including a factor indexing the ability to tolerate discomfort and pain (Factor 1: alpha = .91), and a factor, which appears to measure avoidance of physical discomfort (Factor 2: alpha = .72). Cross-time reliability shows good stability across 12 weeks (Factor 1 = .63, Factor 2 = .66). Convergent and discriminant validity coefficients indicated that the DIS performed as expected against established measures of psychopathology. The DIS appears to be a sound measure of a broad individual difference variable tapping the ability to tolerate a variety of uncomfortable sensations and may be relevant to the pathogenesis of anxiety disorders.
引入了不适耐受度这一概念（被视为个体在耐受不适感觉能力方面的差异），并给出了该特质测量方法的心理测量特性。使用多种样本（总数N约为1700）对不适耐受度量表（DIS）进行了评估，这些样本包括惊恐障碍患者、临床对照者和非临床社区成员。因素分析表明，DIS包含两个因素，一个因素反映耐受不适和疼痛的能力（因素1：α = 0.91），另一个因素似乎测量对身体不适的回避（因素2：α = 0.72）。跨时间信度显示在12周内具有良好的稳定性（因素1 = 0.63，因素2 = 0.66）。聚合效度和区分效度系数表明，DIS在与既定精神病理学测量方法的对比中表现符合预期。DIS似乎是一种可靠的测量方法，可用于衡量个体在耐受各种不适感觉能力方面的广泛差异变量，可能与焦虑症的发病机制相关。
