In the study of social anxiety, it is common to differentiate between social interaction versus performance anxiety. The Social Interaction Anxiety Scale was designed to assess social interaction anxiety, and the Social Phobia Scale to assess fear of scrutiny by others (Mattick and Clarke, 1989). In common use, these scales are typically administered together and treated as subscales of a larger measure. However, the joint factor structure of these instruments has never been examined; therefore, it is unclear whether or not the items on these scales actually represent distinct aspects of social anxiety. In the present study, a confirmatory factor analysis of the pooled items from the SIAS and SPS failed to adequately fit the data. An exploratory factor analysis yielded three factors: (1) interaction anxiety, (2) anxiety about being observed by others, and (3) fear that others will notice anxiety symptoms. However, hierarchical factor analysis suggested that these factors all load on a single higher-order factor, social anxiety. Relationships of the first-order factors to other measures of social and performance fear and avoidance are examined, and implications of our findings for the assessment of social phobia are discussed.
在社交焦虑的研究中，区分社交互动焦虑与表现焦虑是很常见的。社交互动焦虑量表旨在评估社交互动焦虑，社交恐怖量表则用于评估对他人审视的恐惧（马蒂克和克拉克，1989年）。在实际应用中，这些量表通常一起使用，并被视为一个更大测量工具的子量表。然而，这些工具的联合因子结构从未被研究过；因此，不清楚这些量表上的项目是否真的代表了社交焦虑的不同方面。在本研究中，对社交互动焦虑量表（SIAS）和社交恐怖量表（SPS）汇总项目进行的验证性因子分析未能充分拟合数据。探索性因子分析产生了三个因子：（1）互动焦虑，（2）担心被他人观察，以及（3）害怕他人会注意到焦虑症状。然而，层次因子分析表明，这些因子都加载在一个单一的高阶因子——社交焦虑上。研究了一阶因子与社交和表现恐惧及回避的其他测量指标之间的关系，并讨论了我们的研究结果对社交恐怖症评估的意义。
