The UK Trauma Council has developed nine principles informed by an understanding of complex trauma, its effect on child development, and evidence-based responses that care givers, professionals and services can engage in to address the impacts of complex trauma.


  1. Establishing a common definition of complex trauma
  2. Promoting and stabilising trusted relationships
  3. Cultivating supportive interactions
  4. Actively enabling young people’s agency
  5. Recognising adaptations and building social connections
  6. Holistically responding to multiple needs
  7. Providing evidence-based interventions
  8. Tackling contextuality and systemic factors
  9. Supporting the workforce
