The aim of the study was to investigate levels of posttraumatic stress due to the recent economic crisis in a Greek community sample and identify particularly vulnerable demographic groups. A sample of 1,208 residents of a western Athens borough completed the Impact of Events Scale-Revised. According to the findings, almost 60% of respondents reported severe and 28% moderate symptoms. Individuals in employment presented similar levels as the unemployed, while caring for dependants, having lower educational attainment, and being female and older were associated with greater posttraumatic stress. The present findings suggest a high prevalence of posttraumatic stress in a community sample, indicating that policymakers in Greece, Europe, and worldwide need to take very seriously the growing evidence for the detrimental effects of austerity politics on both individual and collective well-being.
