The frequency and severity of the symptoms of generalized anxiety disorder (GAD) were determined in a sample of 49 patients with the DSM-III-R diagnosis of GAD. The frequency of the symptoms was considered to meet the DSM-III-R requirement of "often" if the symptoms were present for at least 3 days in every week over a 6-month period. The severity of the symptoms was rated on a 5-point scale. Seven symptoms, all of which belong to the clusters of motor tension and vigilance and scanning, were identified as both frequent and at least moderate in terms of their intensity. They were provisionally designated as the "criterion symptoms" of GAD, in contrast to the symptoms of autonomic hyperactivity, which were found to be less frequent and, especially, less intense. A more simplified conceptualization of GAD was proposed on the basis of these findings.
在49名被诊断为符合《精神疾病诊断与统计手册》第三版修订版（DSM-III-R）标准的广泛性焦虑症（GAD）患者样本中，确定了广泛性焦虑症症状的出现频率和严重程度。如果症状在6个月期间内每周至少出现3天，则认为症状出现频率符合DSM-III-R中“经常”的要求。症状严重程度采用5分制进行评分。有7种症状，均属于运动紧张以及警觉和扫描症状群，在出现频率和强度方面均被确定为既频繁又至少为中度。与自主神经功能亢进症状相比，后者出现频率较低，尤其是强度较弱，这7种症状被暂时指定为广泛性焦虑症的“标准症状”。基于这些发现，提出了一种对广泛性焦虑症更简化的概念化认识。
