越轨同伴交往和暴力媒体接触及攻击规范信念对青少年欺负行为的作用

Role of deviant peer affiliation,exposure to violent media,and normative beliefs about aggression in adolescent bullying behavior

目的探讨越轨同伴交往(DPA)、暴力媒体接触(EVM)及攻击规范信念(NBA)对青少年欺负行为的作用。方法选取777名中学生为研究对象,采用DPA、EVM、NBA量表及青少年欺负问卷调查中学生的DPA、EVM、NBA及青少年欺负行为情况,采用Pearson相关分析上述4个内容的相关性,结合PROCESS模型6检验DPA、EVM和NBA对青少年欺负行为的影响,并检验EVM和NBA在DPA和青少年欺负行为之间的作用。结果DPA与EVM、NBA和青少年欺负行为之间两两正相关(P<0.01);DPA对青少年欺负行为的直接效应显著(β=0.20,95%CI为0.22~0.35),EVM和NBA在DPA与青少年欺负行为之间的3条中介路径均有统计学意义(总中介效应值为0.09、占比31.36%,95%CI为0.06~0.12)。结论EVM和NBA分别在DPA和青少年欺负行为之间起中介作用,且存在DPA、EVM、NBA、欺负行为的链式效应。

Objective To explore the effects of deviant peer affiliation(DPA),exposure to violent media(EVM)and normative beliefs about aggression(NBA)on adolescent bullying behavior.Methods A total of 777 middle school students were selected as the research subjects.DPA scale,EVM Questionnaire,NBA scale and adolescent bullying questionnaire were used to investigate DPA,EVM,NBA,and adolescent bullying behavior of middle school students.Pearson correlation analysis was used to analyze the correlation between above four items.PROCESS Model6 was applied to examine the impact of DPA,EVM,and NBA on adolescent bullying behavior,as well as the role of EVM and NBA in DPA and adolescent bullying behavior.Results DPA,EVM,NBA,and adolescent bullying behavior positively correlated with each other(P<0.01).The direct effect of DPA on adolescent bullying behavior was significant(β=0.20,95%CI was 0.22-0.35).EVM and NBA had three statistically significant mediating paths between DPA and adolescent bullying behavior(total mediating effect value=0.09,accounting for 31.36%,95%CI was 0.06-0.12).Conclusion EVM and NBA play a mediating role between DPA and adolescent bullying behavior,respectively.There is a chain mediating effect of DPA,EVM,NBA,bullying behavior.
