摘　　要：目的考评青少年焦虑情绪障碍筛查表(SCARED-41)在汶川地震灾区中学生焦虑评价中的信效度。方法采用多阶段整群随机抽样方法。抽取3所中学初一、初二、高一、高二年级学生共计2729人,采用SCARED-41进行问卷调查。应用信度分析、探索性因子分析和验证性因子分析方法考评其信度和效度。结果 SCARED-41的5个焦虑因子的奇偶分半信度在0.734～0.860间,总量表0.940。5个焦虑因子的Cronbach’α系数在0.646～0.862间,总量表0.937。探索性因子分析共提取7个公因子,累积贡献49.9%。其中,社交恐怖贡献最大,为11.9%,提取到了原假设的所有条目;其次是躯体化/惊恐和广泛性焦虑。验证性因子分析表明,合并躯体化/惊恐和广泛性焦虑为一个因子的修改模型比原量表模型结构进一步改善,符合心理测量学要求。结论 SCARED-41具有较好的信度和效度,适合在灾区青少年的焦虑评定中推广应用。Objective To test the reliability and validity of the Screen for Child Anxiety Related Emotional Disorders（SCARED-41） in high school students in the 5.12 Wenchuan Earthquake stricken areas.Methods A multistage cluster random sampling method was adopted to select 2729 year 10 and year 11 students from three high schools in the earthquake stricken areas for the questionnaire survey using SCARED-41.The internal consistency and construct validity of the SCARED-41 were evaluated through Cronbach＇s alpha and exploratory and confirmatory factor analyses,respectively.Results The Guttman split-half correlation for the SCARED-41 was 0.940,with the five subscales ranging from 0.734 to 0.860.The Cronbach＇s alpha for the SCARED-41 was 0.937,with the five subscales ranging from 0.646 to 0.862.Seven common factors were extracted from the exploratory factor analysis,with a percentage of cumulative explained variance of 49.9%.Social phobia contributed the most,which accounted for 11.9% of the total variance and retained all prior assigned items.Somatic/panic and general anxiety came second.The confirmatory factor analysis showed that a modified model combining the somatic/panic and general anxiety factors as one generated a better fit than the originally assumed construct.Results SCARED-41 has good psychometrics properties.With adequate reliability and validity,SCARED-41 can be widely applied for assessing anxiety of students in earthquake stricken areas.
