背景Liebowitz社交焦虑量表（LSAS-CA）的临床管理版本是一种常用的评估工具，用于评估社交焦虑障碍，并已被证明具有很强的心理测量学特征。由于其明显的简单的评级格式和潜在的节省时间和精力，使用LSAS作为自我报告（LSAS-SR）措施的兴趣有所增加，LSAS-SR已被用于一些研究。然而，LSAS-SR的心理测量学特性尚未得到很好的建立。本研究在99名被初步诊断为社交焦虑障碍的个体和53名无精神障碍的个体中，比较了LSAS-SR和LSAS-CA的心理测量学特性。两个版本的LSAS在任何量表或子量表得分上几乎没有差异。这两种形式是内部一致的，两种形式的分量表相互关系基本相同。各LSAS-SR指标与LSAS-CA指标的相关性均达到高度显著水平。最后，两种形式的LSAS的收敛性和判别效度都很强。本研究的结果表明，自我报告版本的LSAS相比，以及临床医生管理的版本，可有效地用于评估社交焦虑障碍。
Background. The clinician-administered version of the Liebowitz Social Anxiety Scale (LSAS-CA) is a commonly used assessment device for the evaluation of social anxiety disorder and has been shown to have strong psychometric characteristics. Because of its apparently straightforward rating format and potential savings in time and effort, interest in the use of the LSAS as a self-report (LSAS-SR) measure has increased, and the LSAS-SR has been used in a number of studies. However, the psychometric properties of the LSAS-SR have not been well established.Methods. This study examined the psychometric properties of the LSAS-SR in comparison to the LSAS-CA in a sample of 99 individuals with a primary diagnosis of social anxiety disorder and 53 individuals with no current psychiatric disorder.Results. There was little difference between the two versions of the LSAS on any scale or subscale score. Both forms were internally consistent and the subscale intercorrelations for the two forms were essentially identical. Correlations of each LSAS-SR index with its LSAS-CA counterpart were all highly significant. Finally, the convergent and discriminant validity of the two forms of the LSAS was shown to be strong.Conclusion. Results of this study Suggest that the self-report version of the LSAS compares well to the clinician-administered version and may be validly employed in the assessment of social anxiety disorder.
