目的:了解儿童焦虑敏感性指数(CASI)在中国青少年群体中的效度。方法:对2850名中小学生施测儿童焦虑敏感性指数、儿童焦虑相关情绪障碍筛查量表(SCARED)、加州大学创伤后应激反应指数修改版(UCLA PTSD IN-DEX)、儿童抑郁自评问卷(DSRSC)和特质焦虑问卷(TAI)。结果:①将样本随机分为两半进行探索性因素分析和验证性因素分析,探索性因素分析显示该量表包括3个因子,分别为躯体关注、精神关注和社交关注,累计贡献率为44.2%;验证性因素分析发现该模型拟合指数良好(χ2/df=3.53;GFI=0.962;NFI=0.924;CFI=0.944;RMSEA=0.042);②CASI得分与各类焦虑症状呈现出中等程度的相关(r=0.426-0.618),具有良好的汇聚效度;③CASI与特质焦虑中等相关,在考虑特质焦虑的情况下,CASI能在很大程度上增加对焦虑的预测效度(β=0.528,P=0.00,ΔR2=0.107);对抑郁的预测效度增加相对较小(β=0.119,P=0.00,ΔR2=0.011),具有良好的区分效度。结论:CASI中文版具有良好的效度,可作为我国儿童和青少年焦虑敏感性的评价工具。
Objectives: To understand the validity of Children’s Anxiety Sensitivity Index (CASI) in Chinese adolescents. Methods: A total of 2850 primary and secondary school students were enrolled in this study. The children’s anxiety sensitivity index, SCARED, UCLA PTSD IN-DEX, Questionnaire (DSRSC) and Trait Anxiety Questionnaire (TAI). Results: ①The samples were randomly divided into two halves for exploratory factor analysis and confirmatory factor analysis, exploratory factor analysis showed that the scale includes three factors, body care, mental attention and social attention, the cumulative contribution rate was 44.2 %; The confirmatory factor analysis found that the model fitting index was good (χ2 / df = 3.53; GFI = 0.962; NFI = 0.924; CFI = 0.944; RMSEA = 0.042); ②CASI score and all kinds of anxiety symptoms showed a moderate correlation (r = 0.426-0.618), and had good convergence validity. ③CASI was moderately related to trait anxiety, and CASI increased the predictive validity of anxiety to a great extent (β = 0.528, P = 0.00, ΔR2 = 0.107). The predictive validity of depression was relatively small (β = 0.119, P = 0.00, ΔR2 = 0.011), with good discriminant validity. Conclusion: The Chinese version of CASI has good validity and can be used as an evaluation tool for the anxiety sensitivity of children and adolescents in China.
