校园排斥对初中生外化问题行为的影响：有调节的中介效应

为考察初中生外化问题行为的心理机制，研究采用青少年行为自陈量表、青少年遭受校园排斥问卷、领悟社会支持量表、冷酷无情特质量表对黑龙江、福建两省的1284名初中生进行调查。结果表明：（1）校园排斥对初中生的外化问题行为具有正向预测作用；（2）冷酷无情特质在校园排斥与外化问题行为之间具有中介作用；（3）领悟社会支持调节了初中生冷酷无情特质对校园排斥与外化问题行为中介过程的后半段路径。研究结果为初中生群体的校园排斥、冷酷无情特质、领悟社会支持和外化问题行为之间的动态关系提供了有效的数据支持。

The Influence of Campus Exclusion on the Behavior of Externalization Problems of Junior Middle School Students: A Mediating Effect with Regulation

In order to investigate the psychological mechanism of the externalization problem behavior of junior middle school students, 1284 junior middle school students in Heilongjiang and Fujian provinces were investigated by using the Adolescent Behavior Self-report Scale, Adolescent Campus Exclusion Questionnaire, Perceived Social Support Scale and Callous-unemotional Trait Scale. The results were as follow: 1) campus exclusion had a positive predictive effect on the externalization behavior of junior middle school students; 2) callous-unemotional trait played a mediating role in the relationship between campus exclusion and externalizing problem behaviors; 3) the second half path of middle school students’ callous-unemotional traits to the mediation process of campus exclusion and externalization problems behavior was regulated by perceived social support. The results provided effective support for the dynamic relationship between campus exclusion, callous-unemotional trait, perceived social support, and externalization problem behavior of junior middle school students.
