Research reveals extent of trauma caused by Russian invasion of Ukraine

It is the first study to assess CPTSD prevalence in an active warzone

Addressing the post-traumatic stress caused by the Russian war on Ukraine should play a significant part in the humanitarian response to the conflict, according to new research.

The study, co-led by Edinburgh Napier University’s Professor Thanos Karatzias, is the first to ever assess the prevalence of complex posttraumatic stress disorder (CPTSD) in an active warzone – and comes as the first anniversary of the invasion approaches.

It found 40.5% of the 2,000 participants, made up of adults living in Ukraine between July and September 2022, met the global standard threshold for either PTSD or CPTSD. This compares to a prevalence of 26.5% detected in recent analysis of adult survivors of war and around 10% or less in places unaffected by conflict.

The rates were higher in the east of the country, already occupied by Russia in recent years, although people in every region had been severely affected. Respondents also reported very high rates of war-related stressors, such as having an experience of threat to their personal safety, financial security, or local environment.

It is hoped the research could help inform measures to support Ukrainians impacted by the war.

Professor Karatzias, from ENU’s School of Health and Social Care, said: “Almost a year on from Russia’s invasion of Ukraine, we are beginning to understand the extent of the psychological toll it will be taking on civilians.

“We found people have often been exposed to several potentially traumatic events in that time, whether it is hearing an air-raid siren, facing the destruction of local infrastructure or losing a loved one.

“If and when this war ends, we will need to think about ways we can help people move on with their lives. The humanitarian response, which is already hugely complex, will require some innovative thinking to address these psychological harms.”

Among the other findings were a higher prevalence of CPTSD (compared to PTSD) among female respondents, suggesting the conditions of war in Ukraine have left women more vulnerable to it than men. CPTSD is a more complex condition than PTSD – based on six clusters of symptoms – and may require longer interventions for recovery.

The report also notes that existing trauma treatments would likely be beneficial to support those affected by this conflict – with online delivery a potential solution, given the geographically dispersed population.
