中学生攻击行为与自感青春发动时相及学校因素的关系

Association of aggressive behavior with perceived pubertal timing and school factors in middle school students

目的按不同性别探索中学生攻击行为与自感青春发动时相及学校因素的关系。方法对2 791名中学生进行青春发育状况、攻击行为的问卷调查。结果不同自感青春发动时相中学生攻击行为得分差异有统计学意义(F=14.676,P<0.05);不同学校风气、师生关系、同学关系、好朋友数中学生攻击行为得分差异有统计学意义(P<0.05);多重线性回归显示,男生攻击行为的影响因素为学校风气、自感青春发动时相、师生关系(β分别为-0.134、-0.114、-0.098,P<0.05);女生攻击行为的影响因素为师生关系、好朋友数、学校风气、自感青春发动时相(β分别为-0.120、-0.103、-0.102、-0.089,P<0.05)。结论自感青春发动时相及学校因素对中学生攻击行为的影响存在性别差异,在预防上应将时相偏离(提前或推迟)的男生,时相提前的女生列入重点对象。

Objective To explore the relationship between perceived pubertal timing together with school factors and the aggressive behavior in middle school students with different genders. Methods A total of 2 791 middle school students were surveyed by a questionnaire for youth development status and aggressive behavior. Results The score of aggressive behavior was significantly different in middle school students with different perceived pubertal timing （F=14.676, P〈0.05）. The score of aggressive behavior was significantly different in middle school students with different general mood of school, relationship between classmates and teachers and the number of close friends （P〈0.05）. Multiple linear regression analysis indicated that the influencing factors of male students’ aggressive behavior were general mood of school, perceived pubertal timing and the relationship with teachers （β=-0.134, -0.114, -0.098, respectively, P〈0.05）. The influencing factors of female students’ aggressive behavior were the relationship with teachers, the number of close friends, general mood of school and perceived pubertal timing （β=-0.120, -0.103, -0.102, -0.089, respectively, P〈0.05）. Conclusion Perceived pubertal timing together with school factors has significant impact on aggressive behavior in middle school students with different genders. As for the prevention of aggressive behavior in middle school students, school policies should aim at the male students with off-time perceived pubertal timing and the female students with early perceived pubertal timing.
