Post-traumatic growth (PTG) and specific traumatic events have been poorly explored in the literature focusing on post-traumatic stress disorder (PTSD) among healthcare workers (HWs) tackling the COVID-19 pandemic. In a large sample of Italian HWs, we investigated the kinds of traumatic events and whether PTG affects the risk of PTSD, along with its prevalence and features, during the first COVID-19 wave. COVID-19-related stressful events, Impact of Event Scale-Revised (IES-R) and PTG Inventory-Short Form (PTGI-SF) scores were collected through an online survey. Out of 930 HWs included in the final sample, 257 (27.6%) received a provisional PTSD diagnosis based on IES-R scores. Events referring to the overall pandemic (40%) and to a threat to a family member (31%) were reported as the most stressful events. Female sex, previous mental disorders, job seniority, unusual exposure to sufferance and experiencing a threat to one's family significantly increased the provisional PTSD diagnosis' risk, while being a physician, the availability of personal protective equipment and moderate/greater scores on the PTGI-SF spiritual change domain were found to be protective factors.
