Psychological effects of the November 1999 earthquake in Turkey: an epidemiological study

Abstract

Objective: This study assessed the traumatic stress symptoms and related factors in two towns affected by two earthquakes, which killed 20000 people in 1999 in Turkey.

Method: A total of 430 people in selected households were seen 18 months after the earthquake. They were given a self-report questionnaire assessing post-traumatic stress (PTSD) and depressive symptoms, demographics and trauma exposure.

Results: The rates of PTSD and depression were higher in the site closer to the epicenter. The traumatic stress symptom checklist scores were predicted by fear during earthquake, loss of friends and neighbours, female gender, lower education and living in rented accomodation. Depression was predicted by study site, death of relatives and past psychiatric illness.

Conclusion: These results show that severe earthquakes can cause long-lasting morbidity. Our previous findings that showed a differential prediction for depressive and traumatic stress symptoms after earthquakes are also supported.
