Correlation of perceived social support and posttraumatic stress. The total sum score of questionnaire F-Sozu and post-traumatic stress disorder (PTSD) score is shown. Severity of PTSD was verified with the Post-Traumatic Stress Syndrome 10-Questions Inventory (PTSS-10) score. Diagnosis of an increased risk for development of PTSD was related to a cutoff score of 35 or more in PTSS-10. The cutoff score is denoted by a broken horizontal line; social support was significantly correlated to severity of PTSD (Pearson correlation; p < 0.05).
