背景关于社交恐惧症亚型的流行病学数据很少，其定义特征也存在争议。因此，本研究探讨的患病率和描述性特征的经验得出的社交恐惧症亚组在一般人群中。为了揭示亚型，社交困扰，功能障碍，社交恐惧和回避型人格障碍的标准，从以前发表的流行病学研究188个社交恐惧症的数据提取，并进入分层聚类分析。通过比较社交恐惧量表（SPS）和社交焦虑量表（SIAS）的聚类来评估标准效度。最后，进行了配置文件分析，其中集群进行了比较的一组社会人口和描述性特征。出现了三个集群，包括恐怖症得分高（广义亚型），中间（非广义亚型）或低（离散亚型）的所有变量。点患病率分别为2.0%、5.9%和7.7%。所有亚型在SPS和SIAS上都能区分。普遍的或严重的社交恐惧症往往是过度的教育程度和社会支持水平低的个人。总体而言，公众演讲是最常见的恐惧。虽然可以使用分类的区别，目前的数据表明，在一般人群中的社交恐怖症亚型主要是不同的尺寸沿着轻度-中度-严重的连续体，并随着严重程度的增加，案件的数量下降。
Background. Epidemiological data on subtypes of social phobia are scarce and their defining features are debated. Hence, the present study explored the prevalence and descriptive characteristics of empirically derived social phobia subgroups in the general population.Methods. To reveal subtypes, data on social distress, functional impairment, number of social fears and criteria fulfilled for avoidant personality disorder were extracted from a previously published epidemiological study of 188 social phobics and entered into an hierarchical cluster analysis. Criterion validity was evaluated by comparing clusters on the Social Phobia Scale (SPS) and the Social Interaction Anxiety Scale (SIAS). Finally, profile analyses were performed in which clusters were compared on a set of sociodemographic and descriptive characteristics.Results. Three clusters emerged, consisting of phobics scoring either high (generalized subtype), intermediate (non-generalized subtype) or low (discrete subtype) on all variables. Point prevalence rates were 2.0 %, 5.9 % and 7.7 % respectively. All subtypes were distinguished on both SPS and SIAS. Generalized or severe social phobia tended to be over-represented among individuals with low levels of educational attainment and social support. Overall, public-speaking was the most common fear.Conclusions. Although categorical distinctions may be used, the present data suggest that social phobia subtypes in the general population mainly differ dimensionally along a mild-moderate-severe continuum, and that the number of cases declines with increasing severity.
