青少年生活事件量表在中国农村中学生中的信效度评价

Reliability and validity of Adolescent Self-rating Life Events Checklist among Chinese middle school students living in rural areas

目的重新评估青少年生活事件量表(Adolescent Self-rating Life Events Checklist, ASLEC)的信效度并加以修订,以适合中国农村地区中学生群体应用。方法采用多阶段分层整群抽样法,对中国5省(安徽、云南、广东、黑龙江、湖北)15个农村地区共15 607名中学生进行问卷调查。结果经探索性因子分析和验证性因子分析,剔除条目5,17后共包括受惩罚、人际关系、学习压力、丧失、适应5个因素的修订版(ASLEC-R),可解释55.22%的总体方差变异。各拟合指标分别为RMSEA=0.06,GFI=0.91,CFI=0.88,TLI=0.86,NFI=0.88,AGFI=0.88,HOELTER 0.05=261。ASLEC-R的Cronbachα系数为0.92,分半信度为0.87,重测信度为0.84。总量表及各分量表Cronbachα系数均较修订前有所上升。5种联合项目分析结果显示,各条目的鉴别力、关联性、贡献度、同质性和灵敏度良好。与攻击问卷和情绪管理量表的关联系数分别为0.38,-0.36(P值均<0.01)。结论 5因素结构的ASLEC-R信效度良好,适合在中国农村地区使用。

Objective To re-evaluate the reliability and validity of the Adolescent Self-rating Life Events Checklist(ASLEC), and to adapt to the further application to middle school students in rural China. Methods A stratified random cluster sampling method was applied to select 15 607 adolescents from grade 7 th to grade 12 th in 15 rural areas of 5 provinces(Anhui Province, Yunan Province, Guangdong Province, Hei Longjiang Province, Hubei Province), and they were recruited to complete our Questionnaires. Results The revised version(ASLEC-R) consisted of 5 dimensions(punishment, interpersonal relationship, academic pressure, loss and adaptation problem), 25 items after deleting items 5 and 17 through exploratory factor analysis and confirmatory factor analysis, which could accounted for 55.22% of the total variance. The fit indices were RMSEA=0.06,GFI=0.91,CFI=0.88,TLI=0.86,NFI=0.88,AGFI=0.88,HOELTER 0.05=261. The Cronbach’s α and Spearman-Brown split-half reliability coefficient of the whole scale were 0.92 and 0.87, respectively,and the test-retest reliability was 0.84. ASLEC-R had better reliability than the unrevised version. The results of five-joint item analyses showed that each item improved in terms of indiscrimination, relevance, contribution, homogeneity and sensitivity. The correlation coefficients with BWAQ and EI subscale were 0.38 and-0.36 respectively. Conclusion ASLEC-R has good reliability and validity, and it is worth being applied to the Chinese rural areas.
