Abstract

High co-morbidity among mental disorders indicates that common transdiagnostic mechanisms underlie various psychopathology, yet there has been little research effort to empirically explicate transdiagnostic processes. A few existing studies are limited in the number of transdiagnostic mechanisms and mental disorder categories explored. The current study addresses these limitations by examining the relationship between three transdiagnostic processes (experiential avoidance, rumination, and emotion dysregulation) and symptom severity of five mental disorders (generalized anxiety disorder, panic disorder, social anxiety disorder, specific phobia, and depression) in a college sample (N = 266). Applying Structural Equation Modeling (SEM), three transdiagnostic models were evaluated, with the five latent variables of mental disorder regressed onto each transdiagnostic process. The results showed that all transdiagnostic models–except the emotion dysregulation model–generally fit the data well. Among the tested models, the strongest evidence was found for experiential avoidance as a transdiagnostic mechanism underlying multiple disorders, suggesting the need for further research effort to reduce experiential avoidance in diverse clinical populations.

摘要

精神障碍中的高合并症表明常见的跨诊断机制是各种精神病理学的基础，但很少有研究努力从经验上解释跨诊断过程。一些现有的研究在探索的跨诊断机制和精神障碍类别的数量方面受到限制。目前的研究通过检查三种跨诊断过程（经验性回避、反刍和情绪失调）与五种精神障碍（广泛性焦虑症、恐慌症、社交焦虑症、特定恐惧症和抑郁症）的症状严重程度之间的关系来解决这些局限性。大学样本（N = 266）。应用结构方程建模 (SEM)，评估了三个跨诊断模型，将精神障碍的五个潜在变量回归到每个跨诊断过程中。结果表明，所有的跨诊断模型——除了情绪失调模型——通常都能很好地拟合数据。在测试的模型中，最有力的证据表明经验回避是多种疾病的一种跨诊断机制，这表明需要进一步研究以减少不同临床人群的经验回避。
