摘要:Early in the pandemic, the European Journal of Psychotraumatology invited submissions to a Special Issue on the Coronavirus Pandemic and Traumatic Stress. There was a clear need for high-quality research on the potentially traumatic impact of quarantine and social isolation, on the distress and specific needs of vulnerable groups, on which interventions would be needed at different phases of the pandemic and how best to deliver them, and on how to communicate about the pandemic and its consequences - taking culture, gender and age aspects into account. The resulting EJPT COVID Special Issue is a collection of research conducted over the first 18 months of the pandemic and tracks both the development of research and the impact of the pandemic as it occurred in real time. Initially, we published commentary and literature reviews. This was followed by crosssectional research, and eventually longitudinal and intervention studies. The research covered prevalence of trauma-related symptoms and psychopathology within specific vulnerable populations such as healthcare workers, students, children, managers, or more broadly at a country level. In addition, a second research theme was around interventions that targeted COVID-related mental health issues. In this session, together with four authors that contributed to this special issue, we will reflect on what we know about COVID and trauma as a result of this research. The panellists will share some lessons learned about conducting research during a global crisis, and will discuss what they would do differently with the benefit of hindsight.
