校园排斥对初中生内外化问题的影响:同伴关系与核心自我评价的中介作用

该研究探讨了校园排斥和初中生内外化问题的关系，结合资源保存理论，进一步考察同伴关系（条件性资源）与核心自我评价（人格特质资源）对该效应的链式中介作用。采用青少年校园现实受排斥量表、同伴关系量表、核心自我评价量表、焦虑抑郁量表和外化行为倾向量表，对辽宁省2所中学540名初中生进行调查。结果表明：（1）校园排斥对于初中生的内化及外化问题均具有正向预测作用；（2）同伴关系、核心自我评价在校园排斥与内化问题中起完全中介作用，而在校园排斥与外化问题中起部分中介作用。具体而言，校园排斥通过三条路径影响内外化问题：一是同伴关系的单独中介作用；二是核心自我评价的单独中介作用；三是同伴关系—核心自我评价的链式中介作用。

The Effect of Campus Exclusion on Internalizing and Externalizing Problems: Mediating Role of Peer Relationship and Core Self-evaluation

Combining the conservation of resources theory, the study explored the effect of campus exclusion on junior school students' internalizing and externalizing problems, and further investigated the mediating roles of peer relationship(condition resources) and core self-evaluation(personal resources). The survey was conducted by 540 junior school students in two middle schools in Liaoning province with using the tools of reality exclusion scale, peer relationship scale, core self-evaluation scale, anxiety and depression scale and conduct problem tendency inventory. The results showed that: (1) Campus exclusion had a positive predictive effect on both internalizing/externalizing problems among junior school students. (2) Peer relationship and core self-evaluation played a complete mediating role between campus exclusion and internalizing problems, and a partial mediating role between campus exclusion and externalizing problems, and the mediation effects contained the three paths: one was the mediating role of peer relationship; the second was the mediating role of core self-evaluation; the third was the chain-mediated role of both peer relationship and core self-evaluation.
