尽管社交焦虑量表(SIAS)得到了很好的应用和经验支持，但它的因素结构存在问题，并且包括了实用性有问题的反向得分项目。在这里，使用本科生的样本和社交焦虑障碍的客户样本，我们扩展了之前的工作，打开了反向得分的项目是否属于量表的问题。首先，我们成功地确认了先前样本中获得的因素结构。其次，我们发现，反向得分的项目与各种比较指标的相关性一直较弱。第三，我们证明，去掉反向得分的问题通常有助于而不是阻碍SIAS总分的心理测量表现。第四，我们发现反向得分的项目与正常的外向人格特征有很强的相关性，这表明反向得分的项目可能主要评估外向性。鉴于上述结果，我们建议调查人员考虑仅使用SIAs中措辞直白的项目进行数据分析。
Although well-used and empirically supported, the Social Interaction Anxiety Scale (SIAS) has a questionable factor structure and includes reverse-scored items with questionable utility. Here, using samples of undergraduates and a sample of clients with social anxiety disorder, we extend previous work that opened the question of whether the reverse-scored items belong on the scale. First, we successfully confirmed the factor structure obtained in previous samples. Second, we found the reverse-scored items to show consistently weaker relationships with a variety of comparison measures. Third, we demonstrated that removing the reverse-scored questions generally helps rather than hinders the psychometric performance of the SIAS total score. Fourth, we found that the reverse-scored items show a strong relationship with the normal personality characteristic of extraversion, suggesting that the reverse-scored items may primarily assess extraversion. Given the above results, we suggest investigators consider performing data analyses using only the straightforwardly worded items of the SIAS.
