摘要目的:考察敌意认知和愤怒情绪在黑暗人格与大学生网络欺负间的链式中介作用。方法:2022年5—7月，选用黑暗人格三联征量表、网络欺负量表修订版的网络欺负分量表、攻击性问卷中的敌意认知分问卷和愤怒情绪分问卷对4所高校共1 316名大学生进行问卷调查。采用SPSS 26.0和SPSS宏程序PROCESS分别进行描述性分析、Pearson相关分析和中介效应检验等。结果:大学生在过去6个月中的网络欺负检出率为20.29%(267/1 316)。黑暗人格[(34.80±12.11)分]、敌意认知[(21.65±7.25)分]、愤怒情绪[(17.58±5.44)分]和网络欺负[(15.19±3.98)分]两两之间均呈显著正相关( r＝0.16~0.59，均 P<0.01)。中介效应分析结果显示，黑暗人格通过两条路径对大学生网络欺负产生间接影响，一是愤怒情绪的单独中介作用，效应值为0.029 (95% CI＝0.017~0.044)，二是敌意认知和愤怒情绪的链式中介作用，效应值为0.037 (95% CI＝0.023~0.055)。 结论:黑暗人格不仅直接影响大学生网络欺负，还通过愤怒情绪的中介，以及敌意认知和愤怒情绪的链式中介间接作用于大学生网络欺负。

abstractsObjective: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.
