Abstract：
The Social Interaction Anxiety Scale (SIAS) is a globally used scale for clinical diagnostic purposes for social anxiety disorder (SAD). This article investigates the psychometric properties of the SIAS, followed by its adaptation and validation in Urdu. The study consisted of two phases. The initial phase involved the translation of the scale, and the second phase was of a cross-sectional nature and consisted of evaluating factor structure and psychometric properties of the scale. For this purpose, the study enrolled a purposive sample of 573 adults aged between 18 to 45 years (mean [standard deviation (SD)] age: 23.68 [4.28] years) with a diagnosis of SAD. The sample was recruited from educational institutes, hospitals, and clinics in Lahore, Pakistan. The data was collected using a demographic form and the Urdu version of the SIAS, along with the Multidimensional Psychological Flexibility Inventory (MPFI). The analyses of the study were carried out using SPSS V27 and AMOS V24. Confirmatory factor analysis revealed a single factor structure of the Urdu version of the SIAS consisting of 16 items. The psychometric values of the scale shown were excellent, as Cronbach\'s alpha equaled 0.91, convergent validity r equaled 0.37 at p less than 0.01 with psychological inflexibility, and discriminant validity r equaled -0.47 at p less than 0.01 with psychological flexibility. The study concluded that the Urdu version of the SIAS was a valid and reliable measure for the assessment of social anxiety in the Pakistani population.
摘要：
社交焦虑量表（SIAS）是一种全球使用的用于社交焦虑症（SAD）临床诊断目的的量表。本文研究了SIAS的心理测量学特性，其次是它在乌尔都语中的适应和验证。该研究包括两个阶段。初始阶段涉及量表的翻译，第二阶段具有横截面性质，包括评估量表的因子结构和心理测量特性。为此,该研究纳入了573名18~45岁(平均[标准差(SD)]年龄:23.68[4.28]岁)诊断为SAD的成年人的目的性样本.样本是从教育机构招募的，医院,和拉合尔的诊所，巴基斯坦。数据是使用人口统计表格和SIAS的乌尔都语版本收集的，以及多维心理灵活性量表(MPFI)。使用SPSSV27和AMOSV24进行研究分析。验证性因素分析揭示了由16个项目组成的乌尔都语版本的SIAS的单因素结构。显示的量表的心理测量值非常出色，当Cronbach的alpha等于0.91时，收敛效度r在p小于0.01时等于0.37，具有心理僵化，在p小于0.01时，判别效度r等于-0.47，具有心理灵活性。研究得出的结论是，SIAS的乌尔都语版本是评估巴基斯坦人口社交焦虑的有效且可靠的措施。
