Bottom Line: Of the 805 children with a psychiatric disorder, 15.2% had two or more comorbid disorders.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.

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.

Mentions: Figure 1 illustrates the subject flow in the two study phases. Of a total of 9806 students eligible for the screening phase, 434 (4.43%) refused to participate, and 74 did not return the questionnaire. Of the 9298 returned forms, 810 (8.71%) were subsequently excluded because the age of 81 was out of the target range (6–17) and 729 with unqualified SDQ. Therefore, information was collected on 8488 students, comprising completed SDQ from 8055 (86.26%) mothers, 5446 (90.57%) schoolchildren aged 11–17 years and 8418 (89.94%) teachers. Children were defined as screen positives if (1) the emotional and/or conduct section scores was above the 80th percentile cutoff and the impact supplement score was above the 80th percentile cutoff (≥2) for anyone of the three informants; (2) the hyperactivity section score was above the 80th percentile cutoff and the impact supplement score was above the 80th percentile cutoff (≥2) for any two of the three informants. Phase 2 was conducted on all screen-positive participants and on an 11% random sample of screen–negative participants. Of 1129 screen-positive and 804 of 7359 screen-negative schoolchildren, DAWBA face to face interviews were completed for 1824 (94.36%) students, 1535 (79.41%) mothers and 1787 (92.45%) teachers. The mean age of the total sample was 11.0 years (SD 2.3 years), and boys made up 53% of the total sample (662 of 1,251).
