Frequency of Post Traumatic Stress Disorder and Associated Factors Among Survivors of Van Avalanche: 6-Month Follow-up Study.

Objective: We aimed to evaluate the frequency of Post Traumatic Stress Disorder (PTSD), to determine the risk factors, and to monitor the change of symptoms after 6 months among individuals who survived the avalanche disaster in Van.

Method: Face-to-face interviews were conducted with 35 people who were rescued from two consecutive avalanche disasters in Van 2 months and 6 months after the avalanche disaster. The socio-demographic and clinical data of the cases were evaluated. The Post Traumatic Stress Disorder Symptom Scale-Self Report version (PSS-SR) and clinical interviews were used for PTSD diagnosis. The level of trauma was assessed by using the Impact of Event Scale (IES).

Results: All participants were rescuers who went to the avalanche site for rescue mission. Of the cases, 16 were volunteers from the local community and 19 were professional rescuers. The frequency of PTSD was 71.4% in the early assessment, and 57.1% in the long term. Staying in avalanche for more than 30 minutes, the absence of a history of disaster exposure and being in the group of volunteers were found to increase the risk for PTSD development.

Conclusion: There is a high risk of developing PTSD as a result of an avalanche. People who will intervene with the disasters should be educated and prepared in terms of preventing negative psychological consequences of the disaster. The relationship between the severity of trauma and PTSD was replicated in our study.
