Abstract

Background: The Social Interaction Anxiety Scale-6 (SIAS-6) and Social Phobia Scale-6 (SPS-6) are self-reported measures of social anxiety. The aim of this study was to identify the best model for SIAS-6 and SPS-6 using the newly advanced method of exploratory structural equation modeling (ESEM).

Methods: Both confirmatory factor analysis (CFA) and ESEM were utilized to assess the factor structure of the SIAS-6 and SPS-6. Three hundred Korean adults (n _female = 150, aged: 39.28 ± 10.91 years) participated in an online survey and responded to the SIAS-6 and SPS-6 questionnaires.

Results: The findings showed that the bifactor ESEM and bifactor CFA models were a better fit than the other models. General factors had high loading values and reliability coefficients, whereas specific factors had moderate loading values and reliability coefficients. Additionally, measurement invariance across sexes was established.

Conclusion: This study demonstrated that bifactor models provide a unified perspective on the varying viewpoints regarding the relationship between social interaction and social performance anxiety.

社会交往焦虑量表-6和社交恐惧症量表-6在韩国社区样本中的双因素建模。

背景：社交互动焦虑量表-6 （SIAS-6）和社交恐惧量表-6 （SPS-6）是社交焦虑的自我报告测量方法。本研究的目的是利用新的先进的探索性结构方程建模（ESEM）方法来确定SIAS-6和SPS-6的最佳模型。方法：采用验证性因子分析（CFA）和ESEM对SIAS-6和SPS-6的因子结构进行评价。300名韩国成年人（女性150名，年龄39.28±10.91岁）参与了在线调查，并填写了SIAS-6和SPS-6问卷。结果：双因子ESEM和双因子CFA模型的拟合效果较好。一般因子具有较高的载荷值和可靠度系数，而特殊因子具有中等的载荷值和可靠度系数。此外，还建立了跨性别测量不变性。结论：双因素模型对社会交往与社会表现焦虑关系的不同观点提供了一个统一的视角。
