This article presents epidemiological data on the prevalence of DSM-IV generalized anxiety disorder (GAD) and sub-threshold GAD (fulfilling three out of four GAD criteria) in young women together with data on co-morbidity and psychosocial functioning. The prevalence of clinically relevant worry and its predictive validity for the diagnosis of GAD were also examined.
Young women (N = 2064), aged between 18 and 25, from a representative German community sample were diagnosed with a structured clinical interview (ADIS-L, German research version). An additional interview questioned all the participants about the frequency/intensity and uncontrollability of diverse worry topics.
Thirty-seven participants (1.8%) fulfilled the criteria of current GAD (1 week point prevalence) and 56 received a lifetime diagnosis (2.7%); a further 50 participants (2.3%) were diagnosed with sub-threshold GAD. Co-morbidity between GAD and other disorders was high for current (68%) and lifetime GAD (91%). GAD, as well as sub-threshold GAD, showed clearly reduced levels of psychosocial functioning. Whereas worries of low intensity and high controllability were ubiquitous in all subsamples, clinically defined worrying was rarely present in healthy subjects (0.89%) and of adequate predictive accuracy for GAD.
Full GAD and sub-threshold GAD were moderately frequent in young women. Although DSM-IV worry criteria proved to be highly useful, the strictness of the complete GAD-criteria should not lead to absence of attention from subclinical generalized anxiety states in research and practice.
本文呈现了关于年轻女性中《精神疾病诊断与统计手册》第四版(DSM-IV)广泛性焦虑障碍(GAD)及阈下GAD(满足四项GAD标准中的三项)患病率的流行病学数据,以及共病情况和心理社会功能的数据。还对具有临床意义的担忧的患病率及其对GAD诊断的预测效度进行了研究。
从具有代表性的德国社区样本中选取年龄在18至25岁之间的年轻女性(N = 2064),通过结构化临床访谈(ADIS-L,德国研究版)进行诊断。另一次访谈询问了所有参与者关于各种担忧主题的频率/强度和不可控性。
37名参与者(1.8%)符合当前GAD的标准(1周时间患病率),56名获得终生诊断(2.7%);另有50名参与者(2.3%)被诊断为阈下GAD。GAD与其他障碍的共病在当前(68%)和终生GAD(91%)中都很高。GAD以及阈下GAD均显示出心理社会功能水平明显降低。虽然低强度和高可控性的担忧在所有子样本中普遍存在,但临床上定义的担忧在健康受试者中很少见(0.89%),且对GAD具有足够的预测准确性。
完全型GAD和阈下GAD在年轻女性中较为常见。尽管DSM-IV的担忧标准被证明非常有用,但完整GAD标准的严格性不应导致在研究和实践中忽视亚临床广泛性焦虑状态。
