To investigate the aggressive behavior of adolescents in urban areas of Nanjing, and analyze the influence factor of aggressive behavior.

Self-designed General Condition Questionnaire and Achenbach Child Behavior Scale (CBCL for parents ) were applied to 2 339 students aged 12-16 years old in six districts of Nanjing.

(1) The detection rate of aggressive behavior was 3.21%. And it had no stastical difference in gender(χ²=0.00, P>0.05) and in children with or without siblings(χ²=2.83, P>0.05). (2) The score of aggressive factor was (4.55±5.01). The scores of boys’ and girls’ aggressive factor were (4.75±5.13) and (4.35±4.90), respectively. (3) In the aggressive group of boys, significant positive correlations were found between aggressive behavior and other problematic behaviors, including somatic complaints, schizoid, bad communication, compulsion, hostility, discipline and hyperactivity (r=0.74, 0.66, 0.60, 0.55, 0.58, 0.69, 0.59, all P<0.01). In the aggressive group of girls, significant positive correlations were found between aggressive behavior and other problematic behaviors, including anxiety, somatic complaints, depression withdrawal, schizoid, immature, discipline and cruel (r=0.40, 0.41, 0.41, 0.55, 0.56, 0.76, 0.73, all P<0.05). (4) Multivariate logistic regression analysis indicated that poor academic performance (OR=1.75, 95%CI: 1.26-2.42), bad relationship with families(OR=1.96, 95%CI: 1.23-3.12) and poor relationship with surrounding people(OR=2.66, 95%CI: 1.67-4.24) were the main risk factors contributed to aggressive behavior of adolescents(all P<0.05).

Aggressive behavior of adolescents may co-occur with internalizing and externalizing behaviors; besides, poor academic performance and interpersonal relationship may predict the occurrence of aggressive behavior of adolescents.
