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

Abstract

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 7th to grade 12th 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, H0ELTER 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.

Abstract

【摘要】 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査。 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 Cronbach α 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 Cronbach α 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。
