Résumé
Objective:To explore the chain mediating effects of hostile cognition and anger between dark triad and college students' cyberbullying.Methods:From May to July 2022, a total of 1 316 college students from four universities completed a cross-section questionnaire survey including the dirty dozen (DD), the cyberbullying subscale of the revised cyber bullying inventory (RCBI), the hostility cognition and anger subquestionnaires of the aggression questionnaire (AQ). SPSS 26.0 and SPSS PROCESS macro program were used for descriptive analysis, Pearson correlation analysis and mediating effect test.Results:The prevalence of cyberbullying among college students in the past six months was 20.29%(267/1 316). Dark triad (34.80±12.11), hostile cognition (21.65±7.25), anger (17.58±5.44) and cyberbullying (15.19±3.98) were all significantly positively correlated with each other ( r=0.16-0.59, all P<0.01). The results of mediating effect test showed the indirect effect of dark triad on college students' cyberbullying through two pathways, one was the separate mediating effect of anger, and the effect value was 0.029 (95% CI=0.017-0.044), the other was the chain mediating effect of hostile cognition and anger, and the effect value was 0.037(95% CI=0.023-0.055). Conclusion:Dark triad can not only directly affect college students' cyberbullying, but also indirectly affect cyberbullying through the mediating role of anger and the chain mediating role of hostile cognition and anger.
