目的：了解女中学生青春发动时相、攻击行为、外显自尊和亲子依恋的状况,探索青春发动时相与攻击行为之间的关联机制,揭示外显自尊和亲子依恋在青春发动时相提前与攻击行为中的中介作用。方法：采用问卷法,对1 130名女中学生进行青春发育状况、攻击行为、外显自尊、亲子依恋的调查。结果：初中女生外显自尊和父子依恋的得分均高于高中女生（P〈0.01）,高中女生青春发育得分高于初中女生（P〈0.05）。女中学生青春发动时相与攻击行为呈显著正相关关系（P〈0.01）,与母子依恋、外显自尊均呈负相关关系（P〈0.05和P〈0.01）;外显自尊和母子依恋在青春发动时相提前对攻击行为的影响中起部分中介作用,中介作用大小分别为33.87%和25.98%。标准化回归系数7条显著路径,青春发动时相提前、外显自尊和母子依恋均对攻击行为有直接作用,同时青春发动时相提前通过外显自尊和母子依恋对攻击行为产生间接作用。结论：在攻击行为的预防上,引导青春发动时相提前的女中学生,正确把握自尊弹性,改善亲子依恋关系,可缓解和降低青春发动时相提前的女中学生的攻击行为水平。

英文摘要：

Objective： To investigate of the early pubertal development,aggressive behavior,self-esteem and parent-child attachment of middle school girl,explore the mechanism of pubertal development and aggressive behavior,and reveal the intermediary role of selfesteem and parent-child attachment in the early pubertal timing and aggressive behavior of girls. Methods： The pubertal development,aggressive behavior,self-esteem and parent-child attachment of 1130 middle school girls were investigated by questionnaire. Results：The scores of self-esteem and parent-child attachment in middle school girls were higher than those in high school girls（ P〈0. 01）,the score of pubertal development in high school girls was higher than that in middle school girls（ P〈 0. 05）. The early pubertal timing was positively related to aggressive behavior（ P〈0. 01）,and negatively related to self-esteem and parent-child attachment（ P 〈0. 05 and P〈0. 01）. The self-esteem and parent-child attachment played partly mediator effects between early pubertal timing and aggressive behavior,the effects of which were 33. 87% and 25. 98%,respectively. The early pubertal timing,self-esteem and parent-child attachment played directly effects on aggressive behavior,and the early pubertal timing played indirectly effects on aggressive behavior by self-esteem and parent-child attachment. Conclusions： For preventing the aggressive behavior of middle school girls,correct guiding,grasping self-esteem and impoving parent-child attachment can relieve and reduce the aggressive behavior of middle school girls with the early pubertal timing.
