The World Health Organisation’s new diagnostic Criteria, the ICD-11, will be launched this year. Unlike DSM-5, ICD-11 will include the new diagnosis of Complex Post Traumatic Stress Disorder.  

This conference brings together leading academics and clinicians from around Europe to explain and discuss the new diagnosis and its implications for clinical practice and research, with a particular focus on children and young people of school age.   

What will be covered?   

  • Symptomatology of Complex PTSD and how and why the diagnosis came to be.
  • The occurrence of Complex PTSD in different samples of children and young people.
  • How to assess children, young people and families who have been complexly traumatised and the current use of interventions for them.
  • Whether recognised interventions for PTSD are effective for Complex PTSD.
