The Liebowitz Social Anxiety Scale for Children and Adolescents (LSAS-CA-SR) is a validated instrument for the assessment of social anxiety in youth. The three main objectives of the present study were to (a) examine the factor structure of the LSAS-CA-SR; (b) to validate the factors against relevant personality measures, and (c) to create a brief and reliable version of the questionnaire. A total of 1,362 adolescents completed self-report measures of social anxiety, temperament, character and personality traits. The factor structure was examined using a combination of confirmatory and exploratory factor analysis. The analysis was conducted on both the anxiety and avoidance sub-scales, and identical items for both sub-scales were maintained. Two factors emerged: social interaction and school performance. These factors demonstrated high internal consistency and a significant correlation with relevant self-report measures. A brief version comprised of 14 items was highly correlated (0.96) with the full version. The new factor structure represents advancement over the previous efforts, and holds promise for efficient utilization of the LSAS-CA.
儿童和青少年莱博维茨社交焦虑量表（LSAS-CA-SR）是一种经过验证的用于评估青少年社交焦虑的工具。本研究的三个主要目标是：（a）检验LSAS-CA-SR的因子结构；（b）对照相关人格测量指标验证这些因子，以及（c）编制一个简短且可靠的问卷版本。共有1362名青少年完成了社交焦虑、气质、性格和人格特质的自我报告测量。使用验证性因子分析和探索性因子分析相结合的方法检验因子结构。对焦虑和回避子量表均进行了分析，并保留了两个子量表中的相同项目。出现了两个因子：社交互动和学业表现。这些因子显示出高内部一致性，并且与相关自我报告测量指标显著相关。一个由14个项目组成的简短版本与完整版本高度相关（0.96）。新的因子结构代表了比以往研究的进步，并且有望有效利用LSAS-CA。
