Subjects from a family study who had panic disorder and generalized anxiety disorder were compared on the pattern of their symptoms, age and type of onset, personality characteristics, course of illness, and outcome. Subjects with generalized anxiety disorder were shown to have fewer autonomic symptoms and an earlier, more gradual onset. Their illness was also observed to have a more chronic course and a more favorable outcome, although these differences were not statistically significant. The validity of generalized anxiety disorder and panic disorder as discrete diagnostic entities is supported.
对来自一项家族研究中患有惊恐障碍和广泛性焦虑障碍的受试者，在症状模式、发病年龄和类型、人格特征、病程及预后方面进行了比较。结果显示，患有广泛性焦虑障碍的受试者自主神经症状较少，起病更早且更为渐进。他们的疾病也被观察到病程更慢性且预后更良好，尽管这些差异无统计学意义。这支持了广泛性焦虑障碍和惊恐障碍作为不同诊断实体的有效性。
