There is a lack of data systematically describing subthreshold expressions of social anxiety disorder (SAD) with regard to prevalence, comorbidity, and impairment.
This analysis was based on data from the German Health Survey (GHS) and its Mental Health Supplement (GHS-MHS). Social anxiety disorder and its syndromes as well as other mental disorders were assessed with a standardized diagnostic interview (M-CIDI) in 4,174 adults.
The 12-month prevalence rate for threshold SAD was 2.0%, subthreshold and symptomatic social anxiety (one DSM-IV criterion missing/two or more criteria missing) was found in 3.0 and 7.5% of the participants, respectively. As expected, threshold SAD was characterized by an elevated risk for comorbid disorders and associated with impairment in diverse areas of life. However, this was also true for the two subthreshold expressions of social anxiety, which were also significantly associated with higher comorbidity and greater impairment compared to the control group.
Our results suggest that social anxiety below the diagnostic threshold is clearly associated with adverse outcomes. Prospective designs should examine the exact temporal and possible causal pathways of this burden in order to inform prevention and early intervention programs.
缺乏关于社交焦虑障碍（SAD）阈下表现的患病率、共病情况及损害程度的系统性数据。
本分析基于德国健康调查（GHS）及其心理健康补充调查（GHS - MHS）的数据。采用标准化诊断访谈（M - CIDI）对4174名成年人评估社交焦虑障碍及其综合征以及其他精神障碍。
阈上社交焦虑障碍的12个月患病率为2.0%，阈下及有症状的社交焦虑（分别缺失一项DSM - IV标准/两项或更多标准）在参与者中的比例分别为3.0%和7.5%。正如预期的那样，阈上社交焦虑障碍的特征是共病风险升高，并与生活各方面的损害相关。然而，社交焦虑的两种阈下表现也是如此，与对照组相比，它们也与更高的共病率和更大的损害显著相关。
我们的结果表明，低于诊断阈值的社交焦虑与不良后果明显相关。前瞻性研究设计应检查这种负担的确切时间和可能的因果途径，以便为预防和早期干预项目提供信息。
