Abstract:
Objective:To evaluate reliability and validity of the adolescent self-rating life events checklist applied to university students, that can supply the measurement method to accurately evaluate the life events of university students.Methods:The adolescent self-rating life events checklist was carried out on 974 university students from 10 universities in Guangzhou University City by random sampling, with exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed on sample 1 and sample 2 respectively. Results:The new ASLEC includes five factors, including punishment, interpersonal relationship, family stress, loss and learning adaptation, and accumulates 54.706% of the total variance; the revised ASLEC has good structural validity, and the five-factor model fits well (2/df=3.057, 0.001; RMSEA=0.066, CFI=0.903, GFI=0.918, IFI=0.903). The Cronbach's coefficient of the scale is 0.856, and the Cronbach's coefficient of each factor is between 0.537 and 0.860, which meets the requirements of psychometrics; the correlation coefficient between the scale score and the SAS and SDS total scores is 0.538 and 0.574, respectively. There was a significant positive correlation; the test-retest reliability of the scale was 0.862, and the test-retest reliability of each factor was 0.776-0.901. Conclusion:Therefore, the new five-factor structure youth life event scale has good reliability and validity, and can be effectively used in the college students group in the future.
目的:对青少年生活事件量表在大学生群体应用中的信效度进行评价,为客观准确评价大学生的生活事件提供测量工具。方法:采用随机抽样方法对广州大学城10所高校974名大学生进行生活事件自我评定,再分别对样本一和样本二进行探索性因子分析和验证性因子分析。结果:新的ASLEC包括受惩罚、人际关系、家庭压力、丧失和学习适应5个因子,累计解释总方差的54.706%;ASLEC具有良好的结构效度,五因素模型拟合良好(2/df=3.057,0.001;RMSEA=0.066,CFI=0.903,GFI=0.918,IFI=0.903)。该量表的Cronbach’s 系数为0.856,各因子的Cronbach’s 系数在0.537~0.860之间,均符合心理测量学的要求;该量表得分与SAS和SDS总分的相关系数分别为0.538和0.574,均呈显著正相关;该量表的重测信度为0.862,各因子的重测信度为0.776~0.901。结论:新的五因子结构青少年生活事件量表具有良好的信度和效度,今后可以在大学生群体中进行有效运用。
