Age and gender differences in behavioral problems in Chinese children: Parent and teacher reports

This study examined age and gender differences in internalizing and externalizing behavioral problems in a large sample of Chinese children aged 6–15 (N = 4472). The Chinese Child Behavior Checklist (CBCL) and Teacher Report Form (TRF) were used to assess these problems. Results showed that boys were scored higher than girls on externalizing problems by both parents and teachers, while girls were rated higher than boys on somatic problems by teachers. Parent reported externalizing problems tended to decline with age but there was no age effect on internalizing problems except slight increases with age on somatic problems. Older children tended to have higher scores than younger children on anxious and somatic problems as reported by teachers, while aggressive problems showed quadratic association with age, declining until age 10 and thereafter increasing. Parents and teachers tended to report more consistently with boys on externalizing problems but less consistently with boys on anxious and somatic syndromes. Directions for future research were provided.
