This study examined whether peer rejection and affiliation with deviant friends throughout childhood could mediate the link between early disruptiveness and two aspects of delinquent behaviors (i.e., violence and substance use) in a sample of 375 children. Furthermore, we tested whether the two putative mediators operated in a sequential manner or in a parallel manner. Participants' disruptiveness, peer rejection, and friends' deviancy were assessed throughout childhood (ages 7 to 13). Delinquency-related outcomes were assessed at ages 14 and 15 years. Results indicate that the sequential mediational model was supported when delinquency-related violence was the outcome, but not when substance use was the outcome. The discussion stresses the differential role of peer rejection and affiliation with deviant friends in regard to the two outcomes considered in this study and in regard to the time frame when they were measured.
本研究调查了在375名儿童样本中，童年期的同伴排斥以及与不良朋友的交往是否能够介导早期破坏性行为与犯罪行为的两个方面（即暴力和物质使用）之间的联系。此外，我们还测试了这两个假定的中介因素是以顺序方式还是以平行方式起作用。在整个童年期（7至13岁）对参与者的破坏性行为、同伴排斥和朋友的不良行为进行了评估。在14岁和15岁时对与犯罪相关的结果进行了评估。结果表明，当以与犯罪相关的暴力行为作为结果时，顺序中介模型得到了支持，但以物质使用作为结果时则不然。讨论强调了同伴排斥和与不良朋友的交往在本研究中所考虑的两个结果以及测量它们的时间框架方面的不同作用。
