Negative urgency (NU) and distress tolerance (DT) are two similar yet distinct constructs with putative transdiagnostic relevance, particularly across psychopathology characterized by impulsivity (e.g., substance use disorders [SUD], eating disorders featuring binging and/or purging ED-B/P, and borderline personality disorder [BPD]). Yet, there remains a lack of research into NU and DT across SUD, ED-B/P, and BPD symptomatology in clinical populations. The present study sought to elucidate the transdiagnostic utility of NU and DT across impulsive-type psychology by examining the unique and interactive roles of NU and DT across SUD, ED-B/P, and BPD symptomatology within a treatment-seeking sample of young people.
Participants (N = 385; 62.3% female; aged 16-25 years) were recruited from youth health services across Melbourne, Australia. Participants completed an online survey including self-report measures of NU and DT as well as SUD, ED-B/P, and BPD symptoms. Mixed effects logistic regression was used to explore unique and interactive associations of NU and DT with symptoms.
Both NU (adjusted odds ratio [OR ] = 1.22; 95% confidence interval [CI] = [1.16, 1.28]) and global DT (OR = 0.59; 95% CI = [0.47, 0.74]) uniquely predicted symptoms. However, associations with global DT and most of its components differed across psychopathology types. No significant interactions between NU and DT in predicting symptoms were found.
These results support the transdiagnostic utility of NU across SUD, ED-B/P, and BPD, while suggesting the role of DT across these disorders is more nuanced. These findings have important implications for NU and DT as potential intervention targets.
负性冲动（NU）和痛苦耐受力（DT）是两个具有相似但又不同的结构，具有潜在的跨诊断相关性，特别是在冲动性特征的精神病理学中（例如，物质使用障碍[物质使用障碍]、暴食和/或清除 ED-B/P 的进食障碍，以及边缘性人格障碍[边缘性人格障碍]）。然而，在临床人群中，关于 NU 和 DT 在物质使用障碍、暴食和/或清除 ED-B/P、边缘性人格障碍症状中的研究仍然缺乏。本研究旨在通过研究 NU 和 DT 在物质使用障碍、暴食和/或清除 ED-B/P、边缘性人格障碍症状中的独特和交互作用，阐明 NU 和 DT 在冲动型心理学中的跨诊断效用。
参与者（N=385；62.3%为女性；年龄 16-25 岁）是从澳大利亚墨尔本的青年健康服务机构招募的。参与者完成了一项在线调查，包括 NU 和 DT 的自我报告测量，以及物质使用障碍、暴食和/或清除 ED-B/P、边缘性人格障碍的症状。混合效应逻辑回归用于探索 NU 和 DT 与症状的独特和交互关联。
NU（调整后的比值比[OR] = 1.22；95%置信区间[CI] = [1.16, 1.28]）和全球 DT（OR = 0.59；95% CI = [0.47, 0.74]）都能独特地预测症状。然而，与全球 DT 及其大多数成分的关联在不同的精神病理学类型中有所不同。NU 和 DT 在预测症状方面没有显著的相互作用。
这些结果支持了 NU 在物质使用障碍、暴食和/或清除 ED-B/P、边缘性人格障碍中的跨诊断效用，同时表明 DT 在这些障碍中的作用更为复杂。这些发现对 NU 和 DT 作为潜在的干预靶点具有重要意义。
