Abstract:
Objective:To develop the Body Image Flexibility Questionnaire for Middle School Students(BIFQ-MS)and test its validity and reliability.Methods:Firstly,the initial questionnaire was developed based on the hexaflex model of psychological flexibility.Secondly,701 middle school students were selected to complete the initial questionnaire for item analysis and exploratory factor analysis.Thirdly,899 middle school students were ex-amined to conduct confirmatory factor analysis,criterion-related validity and internal consistency tests on the formal questionnaire.The Body Image-Acceptance and Action Questionnaire(BI-AAQ),Avoidance and Fusion Question-naire for Youth(AFQ-Y8),Body Areas Satisfaction Scale(BASS),and General Appearance subscale of the Nega-tive Physical Self Scale(NPSS-GA)were used to test criterion validity.In addition,88 middle school students were retested 4 weeks later.Results:The BIFQ-MS consisted of 26 items,including 4 factors(openness to experience,self-as-context,contact with the present moment,and valued action),which explained 65.55％of the total vari-ance.Confirmatory factor analysis showed that the four-factor structural model fitted well(x2/df=2.26,CFI=0.97,TLI=0.97,RMSEA=0.04,SRMR=0.03).The BIFQ-MS total scores and the scores of each factor were positively correlated with the scores of the BI-AAQ and the BASS(r=0.41-0.50,Ps＜0.01),whereas they were negatively correlated with the scores of the NPSS-GA and the AFQ-Y8(r=-0.28--0.58,Ps＜0.01).The Cronbach's α coefficients of the total questionnaire and the 4 factors ranged from 0.91 to 0.97,and the test-retest reliabilities(ICC)ranged from 0.70 to 0.86.Conclusion:The Body Image Flexibility Questionnaire for Middle School Students is a reliable tool for understanding body image flexibility in adolescents.
