title: Prevalence of psychiatric disorders among children and adolescents in northeast China.
abstract: BACKGROUND
  To describe the prevalence of DSM-IV disorders and comorbidity in a large school-based sample of 6-17 year old children and adolescents in northeast China.
  
  
  METHODS
  A two-phase cross-sectional study was conducted on 9,806 children. During the screening phase, 8848 children (90.23%) and their mothers and teachers were interviewed using the Strengths and Difficulties Questionnaire (SDQ). During the diagnostic phase, 1129 children with a positive SDQ and 804 randomly selected children with a negative SDQ (11%), and their mothers and teachers, were interviewed using the Development and Well-Being Assessment (DAWBA).
  
  
  RESULTS
  The overall prevalence of DSM-IV disorders was 9.49% (95% CI = 8.10-11.10%). Anxiety disorders were the most common (6.06%, 95% CI = 4.92-7.40), followed by depression (1.32%, 95% CI = 0.91-1.92%), oppositional defiant disorder (1.21%, 95%CI = 0.77-1.87) and attention-deficit hyperactivity disorder (0.84%, 95% CI = 0.52-1.36%). Of the 805 children with a psychiatric disorder, 15.2% had two or more comorbid disorders.
  
  
  CONCLUSIONS
  Approximately one in ten Chinese school children has psychiatric disorders involving a level of distress or social impairment likely to warrant treatment. Prevention, early identification and treatment of these disorders are urgently needed and pose a serious challenge in China.
