摘要:The existing evidence suggests that PTSD risk is linked with COVID-19-related stressful experiences (e.g. Conrad et al., 2021), and PTSD rates in young adult samples are higher in comparison to pre-pandemic (e.g. Liu et al., 2020). However, the research on how COVID-19-related restrictions, as well as COVID-19-related health issues, are linked with PTSD and especially, complex PTSD (CPTSD) is still very scarce. In the current study, we aimed to explore the risk of PTSD and complex PTSD in the sample of traumatized young adults in relation to COVID-19-related burden. Method: In total, 1273 university students aged 18-29 participated in the cross-sectional study. The revised version of the Life Events Checklist (LEC-R; Weathers et al., 2013) was used for the assessment of trauma exposure. The ICD-11 PTSD and CPTSD were assessed with The International Trauma Questionnaire (ITQ; Cloitre et al., 2018). The COVID-19-related burden was measured using the five items, representing the levels of burden young adults experienced due to restriction measures and impaired health of their own and their loved ones. Results: The results indicated that 77.3% of young adults in the study sample were exposed to at least one traumatic event over their lifetime. We found high levels of PTSD and CPTSD among the trauma-exposed youth, 9.3% had probable PTSD and 12.8% had probable CPTSD, based on self-report. Conclusions: PTSD and CPTSD risk were associated with higher levels of COVID-19- related distress.
