The widely used Social Interaction Anxiety Scale (SIAS; R. P. Mattick & J. C. Clarke, 1998) possesses favorable psychometric properties, but questions remain concerning its factor structure and item properties. Analyses included 445 people with social anxiety disorder and 1,689 undergraduates. Simple unifactorial models fit poorly, and models that accounted for differences due to item wording (i.e., reverse scoring) provided superior fit. It was further found that clients and undergraduates approached some items differently, and the SIAS may be somewhat overly conservative in selecting analogue participants from an undergraduate sample. Overall, this study provides support for the excellent properties of the SIAS's straightforwardly worded items, although questions remain regarding its reverse-scored items.
广泛使用的社交互动焦虑量表（SIAS；R.P.马蒂克和J.C.克拉克，1998）具有良好的心理测量特性，但关于其因子结构和项目特性仍存在疑问。分析包括445名社交焦虑障碍患者和1689名本科生。简单的单因素模型拟合效果不佳，而考虑到项目措辞差异（即反向计分）的模型拟合效果更佳。进一步发现，患者和本科生对某些项目的理解方式不同，并且在从本科样本中选择模拟参与者时，SIAS可能有些过于保守。总体而言，本研究支持了SIAS措辞直接的项目具有优异特性的观点，尽管关于其反向计分项目仍存在疑问。
