Psychological impairment is shown on the basis of scales of the Symptom Checklist-90-R (SCL-90-R); scores are given as means ± SD. For each of the 90 items a rating on a five-step Lickert scale between 0 (not at all) and 4 (extremely) was possible. Data are presented as T values (mean 50; SD 10). In addition, T values of all patients are presented. For comparison between '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, and 'low-scoring patients' with a PTSS-10 below the cutoff score, a t test for independent samples was used.
