Insights

COVID-19 lockdowns impacted Chinese children, causing depression and post-traumatic stress disorder symptoms (PTSS). Family resilience, particularly a positive outlook, emerged as a key protective factor against these mental health challenges.

Area of Science:

  • Child and Adolescent Psychiatry
  • Mental Health Research
  • Epidemiology

Background:

  • Early 2020 saw Chinese children experiencing severe depression and post-traumatic stress disorder symptoms (PTSS) due to COVID-19 pandemic-related lockdowns and isolation.
  • These measures significantly impacted children's mental and physical development.

Purpose of the Study:

  • To investigate the trajectories of depression and PTSS in children during the COVID-19 pandemic.
  • To examine the protective role of family resilience in mitigating these mental health outcomes.

Main Methods:

  • Latent growth mixture modeling (LGMM) was employed to analyze longitudinal data.
  • 883 children completed three waves of online follow-up questionnaires.

Main Results:

  • Identified distinct trajectories for depression (resilient, recovery) and PTSS (resilient, recovery).
  • Found heterogeneous joint trajectories for depression and PTSS (resilient, chronic).
  • A positive outlook, a facet of family resilience, predicted PTSS trajectories.

Conclusions:

  • Children's depression and PTSS trajectories during the pandemic were diverse with similar subtypes.
  • Family resilience is a critical protective factor for children's mental health during crises.
