Article
The Peritraumatic Distress Inventory (PDI) is a well‐known self‐report questionnaire indexing the distress experienced during and shortly after a most stressful or traumatic event. Although sociodemographic factors contributing to peritraumatic distress have been previously investigated, no research has examined the nature and severity of peritraum...

Preprint
BACKGROUND While exposure to COVID-related stressors, level of peritraumatic distress, and frequency of media use for seeking COVID-related information can increase the risk for trauma- and stressor-related (TSR) symptoms during the pandemic, frequency of social media use for support and connection may buffer these effects. OBJECTIVE We examined t...
Presentation
One of the ‘hot’ topics related to ongoing COVID-19 pandemic is the high prevalence of posttraumatic stress disorder (PTSD) resulting from the global crisis. However, to be diagnosed with PTSD, one must be exposed to an event involving life-threat, which does not necessarily capture the substantial variability in the types of stressors and subseque...
