Shortened forms of the Social Interaction Anxiety Scale (SIAS) and the Social Phobia Scale (SPS) were developed using nonparametric item response theory methods. Using data from socially phobic participants enrolled in 5 treatment trials (N = 456), 2 six-item scales (the SIAS-6 and the SPS-6) were developed. The validity of the scores on the SIAS-6 and the SPS-6 was then tested using traditional methods for their convergent validity in an independent clinical sample and a student sample, as well as for their sensitivity to change and diagnostic sensitivity in the clinical sample. The scores on the SIAS-6 and the SPS-6 correlated as well as the scores on the original SIAS and SPS, with scores on measures of related constructs, discriminated well between those with and without a diagnosis of social phobia, providing cutoffs for diagnosis and were as sensitive to measuring change associated with treatment as were the SIAS and SPS. Together, the SIAS-6 and the SPS-6 appear to be an efficient method of measuring symptoms of social phobia and provide a brief screening tool.
采用非参数项目反应理论方法，制定了社交互动焦虑量表（SIAS）和社交恐惧症量表（SPS）的简短形式。利用 5 项治疗试验中患有社交恐惧症的参与者的数据（N=456），制定了 2 个 6 项量表（SIAS-6 和 SPS-6）。然后，使用传统方法在独立的临床样本和学生样本中对 SIAS-6 和 SPS-6 评分的效标关联效度进行了测试，以及在临床样本中对其变化敏感性和诊断敏感性进行了测试。SIAS-6 和 SPS-6 的评分与原始 SIAS 和 SPS 的评分一样具有相关性，与相关结构的衡量标准的评分也有很好的区分度，能够很好地区分是否患有社交恐惧症，为诊断提供了截断值，并且与 SIAS 和 SPS 一样敏感，可以衡量与治疗相关的变化。总的来说，SIAS-6 和 SPS-6 似乎是一种测量社交恐惧症症状的有效方法，并提供了一种简短的筛查工具。
