Individuals with subthreshold social phobia (SSP) in the community are characterized relative to nonphobic, healthy controls (C), and diagnosed social phobics (SP).
Data from 1488 subjects from the Duke University Epidemiological Catchment Area Study were examined. Bivariate and multivariate methods were used to compare the SSP, SP, and C groups on 10 sets of variables.
Compared with C respondents, SSP respondents were more likely to be female and unmarried and to report less income and education. The SSP respondents were also more likely to report work attendance problems, poor grades in school, symptoms of conduct disturbance, impaired subjective social support, lack of self-confidence, lack of a close friend, use of psychotropic drugs in past year, and a greater number of life changes, chronic medical problems, and mental health visits within the past 6 months. In a multivariate logistic regression model with group membership as the dependent variable, compared with C respondents, SSP respondents were more likely to be female, to have less education, and to report more indicators of poor school performance and symptoms of adolescent conduct disturbance. In contrast, in a similar but separate multivariate model, compared with SP respondents, SSP respondents met the criteria for fewer DSM-III psychiatric disorders and were less likely to report impaired instrumental support.
Social phobia adversely affects over 10% of the population. Previous epidemiologic catchment area-based prevalence estimates have probably been unrealistically low.
社区中患有阈下社交恐惧症（SSP）的个体相对于无恐惧症的健康对照者（C）以及已确诊的社交恐惧症患者（SP）具有不同特征。
对来自杜克大学流行病学集水区研究的1488名受试者的数据进行了检查。采用双变量和多变量方法在10组变量上比较SSP组、SP组和C组。
与C组应答者相比，SSP组应答者更可能为女性且未婚，收入和受教育程度较低。SSP组应答者还更可能报告工作出勤问题、学业成绩差、品行障碍症状、主观社会支持受损、缺乏自信、没有密友、在过去一年中使用精神药物，以及在过去6个月内有更多的生活变化、慢性医疗问题和心理健康就诊情况。在以组成员身份为因变量的多变量逻辑回归模型中，与C组应答者相比，SSP组应答者更可能为女性、受教育程度较低，且报告更多学业成绩差和青少年品行障碍症状的指标。相比之下，在一个类似但独立的多变量模型中，与SP组应答者相比，SSP组应答者符合《精神疾病诊断与统计手册》第三版（DSM - III）精神障碍标准的情况更少，且报告工具性支持受损的可能性更小。
社交恐惧症对超过10%的人口产生不利影响。以前基于流行病学集水区的患病率估计可能一直低得不切实际。
