title: Prevalence and risk factors of behavioral and emotional problems among Chinese children aged 6 through 11 years.
abstract: OBJECTIVE
  To examine the prevalence and risk factors of behavioral and emotional problems in Chinese children.
  
  
  METHODS
  A sample of 2,940 children aged 6 through 11 years was randomly drawn from household registers in Shandong Province of China. Parents completed the Child Behavior Checklist (CBCL) and a structured self-rating questionnaire.
  
  
  RESULTS
  The mean CBCL Total Problems score was 16.1 (SD = 14.0). There was no significant age effect on the Total Problems score; boys scored significantly higher than girls (17.2 versus 15.0; F = 24.94, p < .01). The overall prevalence rates of behavioral problems were 12.5% for boys and 8.3% for girls (chi 2 = 14.23, p < .01). Logistic regression analysis showed that a number of parental, prenatal, perinatal, and postnatal factors were significantly associated with increased risk of children's behavioral problems.
  
  
  CONCLUSIONS
  The prevalence of parent-reported behavioral problems in Chinese children is lower than those found in other countries. Of multiple psychosocial and biological factors associated with children's behavioral problems, separation or divorce of parents is the most significant factor.
