OBJECTIVE Distress tolerance (DT)-willingness to face internal discomforts-has a fuzzy boundary with neuroticism (low emotional stability), raising questions about its independent role in models of personality and mental health. METHOD We investigated DT's overlap with neuroticism and other Big Five factors in a structural model of personality and personality disorder features in samples of university students (N = 1025), emotional disorder patients (N = 225), and substance-use patients (N = 210). RESULTS In exploratory factor analyses, we found that DT indicators clustered with neuroticism and were essentially unrelated to other Big Five domains. Big Five personality dimensions collectively explained approximately 40%-70% of variation in DT, across different samples and methods of quantifying shared variance. CONCLUSIONS We conclude that DT and neuroticism are near neighbors in empirical space and speculate that much of the observed correlation between DT and mental health outcomes in the literature may be carried by shared neuroticism variance. We suggest that clearer distinctions between the two constructs in empirical research could improve our understanding of DT's unique role in the development and treatment of psychopathology.

在大五人格域的结构模型中定义痛苦耐受性。


目标 痛苦耐受力（DT）——面对内心不适的意愿——与神经质（情绪稳定性低）的界限模糊，引发了对其在人格和心理健康模型中的独立作用的质疑。方法 我们在大学生（N = 1025）、情绪障碍患者（N = 225）和物质使用患者（N = 210）。结果在探索性因素分析中，我们发现DT指标与神经质聚集在一起，并且与其他大五领域本质上无关。在不同的样本和量化共享方差的方法中，大五人格维度共同解释了 DT 中大约 40%-70% 的变异。结论 我们得出结论，DT 和神经质在经验空间中是近邻，并推测文献中观察到的 DT 和心理健康结果之间的大部分相关性可能是由共同的神经质方差所带来的。我们认为，在实证研究中更清晰地区分这两种结构可以提高我们对 DT 在精神病理学发展和治疗中独特作用的理解。
