Hypothesis

Are adverse childhood experiences (ACEs) associated with nonsuicidal self-injury (NSSI) or suicidality among Chinese adolescents, and does a supportive school environment modify such associations?

Conclusion

Exposure to adverse childhood experiences increases the risk of nonsuicidal self-injury and suicidality among Chinese adolescents, but supportive school environments can help mitigate these risks.

Supporting Evidence

  • 47.3% of participants had experienced at least 1 adverse childhood experience.
  • Supportive school environments were associated with lower risks of NSSI and suicidality.
  • Emotional abuse was linked to a significant increase in the risk of NSSI.

Takeaway

Kids who have tough childhoods are more likely to hurt themselves or think about suicide, but having a supportive school can help them feel better.

Methodology

This cross-sectional study used data from the 2021 School-Based Chinese Adolescents Health Survey, involving self-reported questionnaires from adolescents in grades 7 to 12 across 326 schools in China.

Potential Biases

Potential recall bias due to self-reported data on ACEs and mental health outcomes.

Limitations

The study's cross-sectional design limits causal conclusions, and reliance on self-reported data may introduce recall bias.

Participant Demographics

The sample included 95,549 adolescents aged 11-21 years, with a mean age of 14.9 years and a gender distribution of 49.8% male and 50.2% female.
