Case study: CPTSD

Leading international research into CPTSD

Research suggests up to 4% of the population may experience posttraumatic stress disorder (PTSD) at any given time. Complex posttraumatic stress disorder (CPTSD) is a more debilitating condition than PTSD and it requires a different treatment approach.

Edinburgh Napier’s Professor Thanos Karatzias of the university’s Centre for Mental Health Practice, Policy & Law Research is a world leading expert in complex posttraumatic stress disorder (CPTSD). He leads various global research projects in this field and through international collaboration with peers working in mental health, he has been instrumental in getting CPTSD officially recognised and diagnosed. 

Achieving global recognition for the diagnosis of CPTSD 

Complex posttraumatic stress disorder (CPTSD) is a relatively new diagnosis. Compared to posttraumatic stress disorder (PTSD), CPTSD is more strongly associated with more frequent trauma, and a greater accumulation of different types of traumatic experiences - such as childhood trauma, abuse, neglect and loss and higher levels of functional impairment.

Professor Thanos Karatzias and researchers from across the globe collaborated to lead the first study in the world describing and establishing CPTSD as a new condition. This research included studies into the prevalence of CPTSD and suitable interventions.

This research included studies into the prevalence of CPTSD and suitable interventions.

Working with international peers in the field, Professor Karatzias and colleagues tested and developed reliable and valid measures of CPTSD, including a new assessment tool, the International Trauma Questionnaire (ITQ). This study has been translated into over 30 languages and published in over 70 peer review studies all over the world. The team also developed a new intervention for CPTSD called the ‘Enhanced Skills Training of Effective and Interpersonal Regulation’ (EASTER).

This international collaborative research and work has established CPTSD into the ICD-11, the World Health Organisation’s international classification of diseases 11th revision and the global standard for diagnostic health information.
