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.
