The Questionnaire for Social Support (F-Sozu) was used to compare 'high-scoring patients' with a Post-Traumatic Stress Syndrome 10-Questions Inventory (PTSS-10) score greater than or equal to the cutoff score of 35, indicating an increased risk for development of post-traumatic stress disorder, with 'low-scoring patients' with a PTSS-10 below the cutoff score. Scores are shown as means ± SD. For each of the 22 items a rating between 1 (low support) and 5 (high support) was possible. A post-hoc t test was applied for independent samples. ^aTrend.
