一些代表性人群的研究报告了DSM-III和DSM-III- r广泛性焦虑症（GAD）的患病率；然而，没有社区研究检验更严格的DSM-IV标准对患病率估计和合并症模式的影响。此外，过去基于“终生”症状评估的研究可能导致1年和点患病率估计的上限。数据来自德国一项具有全国代表性的样本研究，4181名18-65岁的成年人接受了为期12个月的慕尼黑复合国际诊断访谈（Munich-Composite International Diagnostic Interview）。严格定义的12个月阈值DSM-IV广泛性焦虑症患病率估计为1.5%；然而，3.6%的应答者在过去12个月中至少表现出广泛性焦虑症阈下综合征。女性（担忧10%，广泛性焦虑症2.7%）和老年受访者（担忧9.3%，广泛性焦虑症2.2%）的担忧和广泛性焦虑症比例更高。考虑到比以前的研究更广泛的诊断范围，GAD病例的高度共病被证实：所有12个月GAD病例中有59.1%符合重度抑郁症的标准，55.9%符合任何其他焦虑症的标准。总之，DSM-IV版广泛性焦虑症的患病率和合并率与DSM-III-R版广泛性焦虑症的患病率并无本质差异。与以前的报告相比，我们的研究结果的微小差异更可能归因于研究方法的差异，而不是DSM-IV诊断标准的变化。(C) 2001 Wiley-Liss, Inc。
Several studies of representative populations have reported prevalence rates of DSM-III and DSM-III-R generalized anxiety disorder (GAD); however, no community study has examined the effect of the stricter DSM-IV criteria on prevalence estimates and patterns of comorbidity. Furthermore, past studies based on "lifetime" symptom assessments might have led to upper-bound 1-year and point prevalence estimates. Data is presented from a national representative sample study of 4,181 adults in Germany, 18-65 years old, who were interviewed for DSM-IV disorders with the 12-month version of the Munich-Composite International Diagnostic Interview. The prevalence rate of strictly defined, 12-month threshold DSM-IV GAD was estimated to be 1.5%; however, 3.6% of respondents presented with at least subthreshold syndromes of GAD during the past 12 months. Higher rates of worrying and GAD were found in women (worrying 10%, GAD 2.7%) and in older respondents (worrying 9.3%, TAD 2.2%). Taking into account a wider scope of diagnoses than previous studies, a high degree of comorbidity in GAD cases was confirmed: 59.1% of all 12-month GAD cases fulfilled criteria for major depression, and 55.9% fulfilled criteria for any other anxiety disorder. In conclusion, prevalence and comorbidity rates found for DSM-IV GAD are not substantially different from rates reported for DSM-III-R GAD. The minor differences in our findings compared to previous reports are more likely attributable to differences in study methodology rather than changes in diagnostic criteria for DSM-IV.
