Professor Thanos Karatzias, Professor of Mental Health and Director of Research at Edinburgh Napier University, said: “We are really excited to have received funding to explore the newly released ICD-11 Post Traumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD) in military personnel for the very first time. CPTSD requires a different, more intensive treatment approach than PTSD but at the moment it is unknown how many people are affected by it.
