本研究的目的是调查的诊断和症状特异性的广泛性焦虑症的模型，有四个主要特征：不容忍的不确定性，积极的信念担心，穷人的问题导向和认知回避。作者比较了17名非共病的广泛性焦虑障碍（GAD）患者和28名非共病的惊恐障碍伴广场恐怖症（PDA）患者，发现只有不耐受不确定性显示出诊断特异性的证据，即，GAD组的不确定性不耐受评分高于PDA组。在症状特异性方面，当两组合并时，所有模型变量均与担忧显著相关，但与身体感觉恐惧、广场恐惧认知和行为回避无关。总之，这些研究结果提供了进一步的支持不容忍的不确定性和广泛性焦虑症之间的联系，并强调了从诊断和症状的角度追求特异性的重要性。(C)2004年爱思唯尔公司All rights reserved.
The goal of this study was to investigate the diagnostic and symptom specificity of a model of GAD that has four main features: intolerance of uncertainty, positive beliefs about worry, poor problem orientation, and cognitive avoidance. The authors compared 17 patients with non-comorbid generalized anxiety disorder (GAD) to 28 patients with non-comorbid panic disorder with agoraphobia (PDA) and found that only intolerance of uncertainty showed evidence of diagnostic specificity, i.e., intolerance of uncertainty scores were higher in the GAD group relative to the PDA group. In terms of symptom specificity, when both groups were combined, all model variables were significantly related to worry but unrelated to fear of bodily sensations, agoraphobic cognitions, and behavioral avoidance. Taken together, these findings provide further support for the link between intolerance of uncertainty and GAD and underscore the importance of pursuing the issue of specificity from both a diagnostic and symptom perspective.
