Aim of the present study was to retrospectively assess the impact of a catastrophic earthquake in a sample of 121 survivors, 50 years after the event. Mean age +/- SD of the responders was 72.2 +/- 6.1 years. The majority of the victims (78%) acknowledged a strong overall impact of the earthquake on their lives, and almost all of them had intense recollection of the event at its anniversary. The most frequent symptom during the 6 months after the earthquake was persistent remembering or "reliving" of the event; women had considerably more often recurrent dreams of the earthquake and distress than did men. Women and young adults at the time of the earthquake appear to be the most vulnerable groups regarding the psychological effects of the event.
