摘要:Since its outbreak over one year ago, the COVID-19 pandemic has had a devastating impact on individuals around the globe. Given the dynamic picture of this pandemic within and between countries, it is crucial to conduct longitudinal studies across the world, to understand how mental health is impacted over time, and in different countries. This symposium presents three longitudinal studies investigating the mental health impact of the pandemic in various countries. The first study (Gilbar et al.) examined risk factors for depression and anxiety during the pandemic in Israel, above and beyond symptom levels reported three years prior to the pandemic. The second study by Armour et al. is a longitudinal three-wave study in a community sample from the UK, which identified heterogeneous trajectories of PTSD, depression, and anxiety symptomatology. The final study (Freedman et al.) presented in this symposium was an international longitudinal study examining risk factors for PTSD, depression, and anxiety during COVID in over 30 countries.
