One hundred eight patients complaining of anxiety were diagnosed using the Anxiety Disorders Interview Schedule and classified into the various anxiety disorder categories as well as major depression. Although patients with a primary diagnosis of generalized anxiety disorder were more chronic than were panic disorder patients, most patients in each category met the DSM-III criteria for generalized anxiety disorder with the exception of simple phobic patients. On the basis of these data, it would seem that generalized anxiety disorder is a residual category within the anxiety disorders, since generalized anxiety disorder symptoms are almost always present. But if one distinguishes anticipatory anxiety, which is often part of panic or phobic disorders, from generalized anxiety, an independent anxiety disorder category emerges. This category is characterized by apprehensive expectation or chronic worry focused on multiple life situations.
对108名主诉焦虑的患者使用焦虑症访谈量表进行诊断,并将其分为各种焦虑症类别以及重度抑郁症。虽然原发性广泛性焦虑症患者比惊恐障碍患者病程更长,但除单纯恐惧症患者外,每个类别中的大多数患者都符合DSM-III中广泛性焦虑症的标准。基于这些数据,似乎广泛性焦虑症是焦虑症中的一个残余类别,因为广泛性焦虑症症状几乎总是存在。但是,如果将通常是惊恐或恐惧症一部分的预期性焦虑与广泛性焦虑区分开来,就会出现一个独立的焦虑症类别。这个类别以对多种生活状况的担忧预期或长期担忧为特征。
