Objective:To test the reliability and validity of the Chinese version of cyberbullying inventory for college students(CICS-CV)in the context of Chinese culture and make preliminary application.Methods:A total of 1 528 college students completed the CICS-CV, and 208 students completed CICS-CV after six months.Trait anger subscale of state-trait anger expression inventory-2, and Buss-Perry aggressive qusetionnaire were used as the criterion of cyberbullying aggression, and depression anxiety stress scales were used as the criterion for cyberbullying victimization to test its validity. Item analysis, exploratory factor analysis, reliability test, calibration validity test and corss-lag analysis were conducted by SPSS 24.0 software, and confirmatory factor analysis was conducted by Mplus 8.3.Results:The results of exploratory factor analysis showed that two factors were obtained named as cyberbullying aggression and cyberbullying victimization, and the factor loadings were 0.59-0.82, 0.59-0.80.Confirmatory factor analysis showed that the fitting index of the double factor model was fitting well ( χ2/ df=2.61, CFI=0.90, TLI=0.89, RMSEA=0.04, SRMR=0.05). The internal consistency coefficient of the two subscales were 0.88, 0.89, and test-retest reliability were both 0.97. There was a significant positive correlation between cyberbullying aggression(victimization) and the criterions( r=0.23-0.42, all P<0.05). Cross-lag analysis of moral disengagement and cyberbullying aggression showed that the first measurement of moral disengagement significantly predicted the second measurement of cyberbullying aggression( β=0.16, t=2.16, P<0.05). Conclusion:The CICS-CV has good reliability and validity, which can be used as an effective tool for evaluating college students' cyberbullying in China.
