欺负现象在学校中无处不在，广泛影响着学龄儿童。过往研究结果显示，受欺负（bully victimization）与同伴排斥（peer rejection）间存在正相关，二者能相互预测，且它们间的关系受到性别等变量的调节。近年来人们认为，欺负/受欺负作为一种社会群体现象，朋友在其中起着重要作用，但有关朋友关系与受欺负的研究还十分有限。本研究选择持续朋友对作为研究对象，结合主客体互倚模型（Actor-Partner Interdependence Model, APIM）与交叉滞后分析，探究朋友对间受欺负与同伴排斥的关系，并进一步分析了不同性别朋友对之间的差异。选用初中生朋友对被试共128对，用问卷法、同伴提名法测量其受欺负和被同伴排斥的程度，使用其初一秋季学期和春季学期两次施测的数据，用Mplus 7.0软件进行结构方程建模。结果表明，受欺负的主体效应、客体效应均显著，同伴排斥的主体效应显著，客体效应不显著；受欺负能预测自身的同伴排斥，同伴排斥能预测朋友的受欺负。以性别为分组变量进行多组比较，男女生模型及路径系数均有较大差异，表明男女生朋友对被试间相互影响的模式有较大差异。

Bullying is everywhere in school context and has a huge impact on children and adolescence. Research has shown bully victimization and peer rejection is related. Peer rejection is the antecedent causal factor and also the result factor of victimization. This relationship is further moderated by gender. Friendship is considered to play an important role in bully/ victimization, but limited are the literatures on friendship and bully victimization. The current study focuses on reciprocal friendship dyads’ victimization and peer rejection, combining the Actor-Partner Interdependence Model and cross-lagged analysis, and compared the differences between different gender groups. Subjects are 128 reciprocal friend dyads in junior high school. Measurements are questionnaire (Olweus Bully/Victim Questionnaire [Chinese version]) and nomination. Data were collected in their first semester (wave 1) and second semester (wave 2). Mplus 7.0 were used on SEM data analysis. Results shows that victimization has significant actor and partner effect, while peer rejection only has a significant actor effect. Victimization can predict peer rejection of oneself; peer rejection can predict victimization of friend. Multiple group analysis shows significant difference between the model of girls and boys, indicating girls and boys have different pattern of influencing each other in friendship dyads.
