Validity and reliability of the Chinese version of the Coparenting Inventory for Parents and Adolescents in middle school students and parents
Objective:To revise the Chinese version of the Coparenting Inventory for Parents and Adolescents(CI-PA)in middle school students and their parents to test the validity and reliability.Methods:Totally 691 middle school students were tested with the adolescent version of CI-PA,924 parents were tested with the parents'version of CI-PA.The sample was split randomly in half,and item analysis and exploratory factor analysis,confirmatory factor analysis,criterion validity analysis and convergent validity test were performed respectively.The Achenbach Youth Self-Report(YSR)and marital satisfaction subscale(MSS)of Olson Enrich Marital Inventory(ENRICH)were used to test the validity of the criterion.Totally 62 students and 70 parents were followed to complete the Chi-nese version of CI-PA 4 weeks after the first investigation.Results:Exploratory factor analysis showed that there were 37 and 25 items in the adolescent version and the parents'version respectively,3 factors were extracted,inclu-ding 3 dimensions of cooperation,triangulation and conflict.The factor loadings of each item ranged from 0.60 to 0.95,and the subscales explained the total variance ranged from 64.56%to 74.06%.Confirmatory factor analysis showed that all the 3 factors models fitted well in adolescent version(x2/df=1.32,1.30,1.41;CFI=0.99,0.99,0.99;TLI=0.99,0.99,0.98;RMSEA=0.03,0.03,0.03)and the parents'version(x2/df=1.20,1.33;CFI=0.99,0.99;TLI=0.99,0.99;RMSEA=0.02,0.03).Cooperation scores of the adolescent version were negatively correlated with the YSR scores(ICC=-0.18--0.27,Ps<0.01),triangulation and conflict scores of the adoles-cent version were positively correlated with the YSR scores(ICC=0.15-0.34,Ps<0.01).Cooperation scores of the parents'version were positively correlated with the MSS scores(ICC=0.52,0.47,Ps<0.01),triangulation and conflict scores of the parents'version were negatively correlated with the MSS scores(ICC=-0.28--0.47,Ps<0.01).The Cronbach's α of 3 dimensions were all above 0.72,the retest reliabilities(ICC)were all a-bove 0.54.Conclusion:The Chinese version of Coparenting Inventory for Parents and Adolescents(CI-PA)is valid and reliable in measuring the coparenting in Chinese adolescence families.
