Abstract

Objective: Although prior research has demonstrated that peers influence both physical aggression and exposure to violence during adolescence, few studies have investigated the extent to which peers play a role in relations between physical aggression and violence exposure. This longitudinal study examined peer pressure for fighting, friends' delinquent behavior, and friends' support for fighting as mediators of relations between exposure to violence through witnessing and victimization, and adolescents' frequency of physical aggression.

Method: Participants were 2,707 adolescents attending three urban middle schools (Mage = 12.4; 52% female; 79% African American, 17% Hispanic/Latino). Participants completed measures of their frequency of physical aggression, witnessing community violence, victimization by violence, and negative life events, and peer variables at four waves within the same school year.

Results: Cross-lagged analyses indicated that the role of peer variables as mediators varied as a function of the type of exposure and the direction of effects. Whereas peer pressure for fighting mediated relations between witnessing violence and changes in physical aggression, friends' delinquent behavior mediated relations between physical aggression and changes in witnessing violence and victimization. In contrast, violent victimization was not associated with changes in any of the peer factors when included in the same model as witnessing violence.

Conclusions: These findings highlight the role of peers as both a cause and a consequence of adolescents' aggressive behavior and exposure to violence. They suggest focusing on peer variables as targets for interventions to disrupt connections between exposure to violence and physical aggression during early adolescence.

同伴因素是城市低收入社区中学生接触暴力与身体攻击之间关系的中介。
研究目的尽管先前的研究表明,同伴会影响青少年的身体攻击行为和暴力暴露,但很少有研究调查同伴在身体攻击行为和暴力暴露之间的关系中发挥了多大作用。这项纵向研究考察了同伴的打架压力、朋友的不良行为和朋友对打架的支持,这些因素是通过目睹和受害而接触暴力与青少年身体攻击频率之间关系的中介因素:参与者为就读于三所城市中学的 2,707 名青少年(年龄 = 12.4;52% 为女性;79% 为非裔美国人,17% 为西班牙裔/拉丁美洲人)。参与者在同一学年的四次波次中完成了对其身体侵犯频率、目睹社区暴力、暴力受害情况、负面生活事件以及同伴变量的测量:交叉滞后分析表明,同伴变量的中介作用因接触类型和影响方向而异。打架的同伴压力在目睹暴力与身体攻击变化之间起中介作用,而朋友的不良行为则在身体攻击与目睹暴力和受害变化之间起中介作用。与此相反,如果将暴力受害与目睹暴力纳入同一模型,则暴力受害与任何同伴因素的变化都无关:这些研究结果强调了同伴在青少年攻击行为和遭受暴力侵害中既是原因也是结果的作用。结论:这些研究结果表明,同伴既是青少年攻击行为和暴力接触的原因,也是其结果,因此建议重点关注同伴变量,将其作为干预措施的目标,以切断青少年早期暴力接触和身体攻击之间的联系。
