Experiencing a situation of extreme danger can lead to serious stress disorders (such as PTSD) that can affect both the victims and the professional helpers. Military operations in Ukraine in the first half of 2022 started an ongoing migration crisis, resulting in the displacement of approximately 3.5 million people to Poland. It is indicated that post-traumatic stress disorders may affect up to one third of adult refugees. Exposure to traumatic stress related to assault, limitation of basic resources, fear, insecurity, death, and a sense of injustice affected the entire population of the country. As a result, refugees, healthcare professionals, uniformed services, volunteers, and NGO workers constitute a group at risk of developing stress-related disorders, including post-traumatic stress disorder (PTSD). The presented recommendations were developed by an interdisciplinary team of experts in the field of psychiatry, clinical psychology, psychotherapy, and family medicine to present systematic guidelines for diagnostic procedures in medical and psychological practice.
