青少年社会支持与攻击的关系:自尊、自我控制的链式中介作用
Relationships between Social Support and Aggression of Adolescents:The Chain Mediating Roles of Self-Esteem and Self-Control

采用社会支持系统量表、自尊量表、自我控制量表、攻击量表对重庆市某中学559名青少年进行调查，再次验证自尊与攻击的关系，并探讨自我控制在社会支持、自尊和攻击间的中介作用以及自尊和自我控制在青少年社会支持和攻击间的链式中介作用。结果显示：（1）社会支持、自尊和自我控制与攻击之间呈显著负相关；（2）自我控制在社会支持与攻击、自尊与攻击关系间均起着完全中介作用；（3）自尊与自我控制在社会支持与攻击关系间起着链式中介作用。因此，社会支持、自尊、自我控制是青少年攻击的重要影响因素，社会支持除了能直接影响青少年的攻击外，还可以通过自尊、自我控制的链式中介作用间接影响其攻击水平。
Aggression is an important index to measure adolescents'psychological quality and mental health.By integrating environment (social support) with psychological factors (self-esteem and self-control),this study aimed to investigate how these factors influenced adolescents'aggression.We tested the mediating role of self-control between social support and aggression,self-esteem and aggression,as well as the chain mediating roles of self-esteem and self-control between social support and aggression.A total of 559 adolescents from a middle school in Chongqing were recruited and completed the Scale of Social Support System,Self-Esteem Scale,Self-Control Scale and Aggression Questionnaires.The results indicated that:(1) social support,self-esteem and self-control were negatively related to adolescents'aggression;(2) social support and self-esteem had influence on aggression through the completely mediating role of self-control;(3) social support also affected adolescents'aggression through the chain mediating roles of self-esteem and self-control.Specifically,social support influenced self-esteem which exerted an effect on self-control,and then self-control had an effect on aggression.Therefore,social support not only directly affected adolescents'aggression,but also indirectly influenced their aggression through the multiple mediating effects of self-esteem and self-control.
