Gender and Longitudinal Measurement Invariance of the Avoidance and Fusion Questionnaire for Youth(AFQ-Y8)
Objective:To test the measurement invariance of the short version of the avoidance and fusion questionnaire for youth(AFQ-Y8)across gender and time.Methods:The AFQ-Y8 was administered twice to investigate the psychologi-cal flexibility of the same group of junior high school students.Results:The results of single-group confirmatory factor analysis showed that the single-factor structural model of AFQ-Y8 fitted well across gender and time points.The results of multi-group confirmatory factor analysis showed that the configural,weak,strong,and strict invariance of the questionnaire across genderand time were all acceptable.Conclusion:The single-factor structure of the AFQ-Y8 emerges as invariant across gender and time.
