To examine the psychometric properties of a newly developed clinician rating scale, the Liebowitz Social Anxiety Scale for Children and Adolescents (LSAS-CA).
A total of 154 children and adolescents participated in an assessment consisting of a diagnostic interview, the LSAS-CA, and other measures of psychopathology and impairment. Sixty-one of these children also participated in a second LSAS-CA administration, by a different rater blind to diagnosis, within 7 days of the initial assessment.
High internal consistency (alpha =.90-.97 for full sample and.83-.95 for social phobia group) and test-retest reliability (intraclass correlation coefficient = 0.89-0.94) were obtained for LSAS-CA total and subscale scores. LSAS-CA scores had stronger associations with measures of social anxiety and general impairment than with a measure of depression. Subjects with social anxiety disorder had significantly higher LSAS-CA scores than subjects with other anxiety disorders and healthy controls. A LSAS-CA cutoff score of 22.5 represented the best balance of sensitivity and specificity when distinguishing between individuals with social phobia and normal controls, whereas a cutoff of 29.5 was optimal for distinguishing social phobia from other anxiety disorders.
Initial findings suggest that the LSAS-CA is a reliable and valid instrument for the assessment of social anxiety disorder.
检验新开发的临床医生评定量表——儿童青少年莱博维茨社交焦虑量表（LSAS-CA）的心理测量特性。
共有154名儿童和青少年参与了一项评估，该评估包括诊断访谈、LSAS-CA以及其他心理病理学和损害测量。其中61名儿童还在初次评估的7天内，由另一位对诊断不知情的评估者再次进行了LSAS-CA评定。
LSAS-CA总分及分量表得分具有较高的内部一致性（全样本的α系数为0.90 - 0.97，社交恐惧症组为0.83 - 0.95）和重测信度（组内相关系数 = 0.89 - 0.94）。与抑郁测量相比，LSAS-CA得分与社交焦虑和总体损害测量的关联更强。社交焦虑障碍患者的LSAS-CA得分显著高于其他焦虑障碍患者和健康对照。在区分社交恐惧症患者与正常对照时，LSAS-CA临界值22.5代表了敏感性和特异性的最佳平衡，而区分社交恐惧症与其他焦虑障碍时，临界值29.5最为合适。
初步研究结果表明，LSAS-CA是评估社交焦虑障碍的可靠且有效的工具。
