Abstract：
Although previous studies have assessed the association between peer rejection and aggression, the results are mixed.
This article presents a meta-analysis of the association between peer rejection and aggression types (overt vs. relational) among children and adolescents.
A total of 61 eligible studies with 70 independent effect sizes were included in the analysis (45,966 participants, Mage = 10.34, SD = 3.13).
First, random-effects meta-analyses were conducted to explore the association between peer rejection and aggression types (overt vs. relational). Next, moderation analyses were conducted based on the Q statistics for categorical variables (culture, reporting method of peer rejection, reporting method of aggression) and the meta-regression analyses for continuous variable (age).
Peer rejection was positively correlated with overall aggression (r = 0.42, 95 % CI [0.38, 0.47], p < 0.001), overt aggression (r = 0.46, 95 % CI [0.38, 0.54], p < 0.001) and relational aggression (r = 0.43, 95 % CI [0.35, 0.51], p < 0.001). This correlation was positive for each type when controlling for other form of aggression. Moderation analyses suggested that reporting method of aggression (self-report vs. peer-nomination vs. adult-report vs. observation), reporting method of peer rejection (self-report vs. peer-nomination vs. adult-report) and culture (collectivist vs. individualist) were moderators of the association between peer rejection and overall aggression. Culture moderated the association between peer rejection and overt aggression, while age moderated the association between peer rejection and relational aggression.
The findings showed a strong positive association between peer rejection and aggression, although this association varied by aggression type and other moderating variables.

摘要：
背景：尽管以前的研究已经评估了同伴排斥和攻击性之间的关联，结果喜忧参半。
目的：本文对同伴排斥与攻击类型(公开与儿童和青少年之间的关系)。
方法：共有61项符合条件的研究纳入分析，这些研究具有70个独立效应大小（45,966名参与者，Mage=10.34,SD=3.13)。
方法：首先，进行了随机效应荟萃分析，以探索同伴排斥和攻击类型之间的关联(公开与关系)。接下来,适度分析是根据分类变量的Q统计量进行的(文化，对等拒绝的报告方法，攻击的报告方法)和连续变量(年龄)的荟萃回归分析。
结果：同伴排斥与总体攻击性呈正相关(r=0.42,95%CI[0.38,0.47],p<0.001)，明显的攻击性(r=0.46，95%CI[0.38，0.54]，p<0.001)和关系攻击性(r=0.43，95%CI[0.35，0.51]，p<0.001)。当控制其他形式的侵略时，每种类型的这种相关性都是正相关的。适度分析表明，攻击性的报告方法(自我报告与同行提名与成人报告vs.观察)，同行拒绝的报告方法(自我报告与同行提名与成人报告)和文化(集体主义与个人主义）是同伴拒绝和整体侵略之间联系的调节者。文化缓和了同伴拒绝和公开侵略之间的联系，而年龄调节了同伴拒绝和关系侵略之间的关联。
结论：研究结果表明，同伴排斥和攻击性之间存在很强的正相关，尽管这种关联因攻击类型和其他调节变量而异。
