核心自我评价对医学生无聊倾向性与攻击行为的中介作用

目的 探讨医学生无聊倾向性、核心自我评价与攻击行为的关系,为攻击行为的预防和干预提供线索与依据.方法 采用大学生无聊倾向性问卷（C-BPQ）、核心自我评价量表、Buss和Perry攻击问卷中文版（AQ-CV）,对宁夏某医科院校1667名学生进行问卷调查.结果 高、低无聊倾向组的核心自我评价、攻击总分及各因子间的差异均具有统计学意义核心自我评价：（29.67±5.10）分,（41.67±4.64）分;攻击总分：（36.43±17.18）分,（17.58±12.45）分;身体攻击性（31.62±20.46）分,（17.02±15.28）分;言语攻击性：（37.44±19.03）分,（24.68±17.14）分;愤怒：（40.93±22.32）分,（18.85±16.86）分;敌意：（37.34± 19.41）分,（14.86±13.57）分;指向自我的攻击：（35.47±21.66）分,（13.57±14.28）分;均P＜0.001];医学生无聊倾向性总分和内、外部刺激两维度与攻击总分及各因子之间存在正相关关系（均P＜0.001）,与核心自我评价之间存在负相关关系（P＜0.001）;核心自我评价与攻击总分及各因子之间存在负相关关系（均P＜0.001）;回归分析显示,无聊倾向性、核心自我评价可以在一定程度上预测医学生的攻击行为（均P＜0.01）;核心自我评价在医学生无聊倾向性与攻击行为间起部分中介作用,中介效应占总效应的比例为48.25％.结论 无聊倾向性与攻击行为密切相关,核心自我评价在二者之间起部分中介作用.

The mediating effect of self-evaluation on boredom proneness and aggression in medical students

Objective To explore the relationship among boredom proneness,core self-evaluation and aggression in medical students and to provide clues and evidence for preventing aggression and their relevant interventions.Methods The Boredom Proneness Scale for College Students（C-BPQ）,Chinese Version of Buss ＆ Perry Aggression Questionnaire （AQ-CV）and Core Self-evaluations Scale were employed to investigate 1667 medical students in one medical university in Ningxia.Results There were significant differences between high and low boredom proneness groups in core self-evaluations,total aggression score and each factors （core self-evaluations：（29.67±5.10） vs （41.67±4.64）,AQ-CV scores：（36.43±17.18） vs （17.58±12.45）,physical aggression：（31.62 ±20.46） vs （17.02 ±15.28）,verbal aggression：（37.44±19.03） vs （24.68±17.14）,anger：（40.93±22.32） vs （18.85±16.86）,hostility：（37.34± 19.41） vs （14.86± 13.57）,self-aggression：（35.47 ±21.66） vs （13.57± 14.28）,all P〈0.001）.There were positive correlation among total score of boredom proneness,internal and external stimuli dimensions,total score of AQ-CV and each factors （P〈0.001） and negative correlation between total score of boredom proneness and core self-evaluation（P〈0.001）.There were negative correlation among core self-evaluation score,AQ-CV scores and each factor（P〈0.001）.Regression analysis showed that boredom proneness and core self-evaluation could predict the aggression to a certain extent （P〈0.01）.Core self-evaluation played a mediating role between boredom proneness and aggression taking 48.25% proportion of the total effect of the mediation.Conclusion Boredom proneness is closely related to aggressive behavior.Core self-evaluation plays a mediating role between boredom proneness and aggression.
