Health-related quality of life (HRQoL) was measured in controls, in '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 PTSD, and in 'low-scoring patients'. HRQoL (results shown as means ± SD) was measured with the Medical Outcomes Study 36-Item Short Form (SF-36) in physical component summary (subdimensions physical function, physical role function, bodily pain and general health) and mental component summary (subdimensions vitality, social function, emotional function and mental health). The difference between groups was evaluated with an analysis of variance (ANOVA) and post-hoc t tests for independent samples. PTSD, post-traumatic stress disorder. aSignificant difference between healthy controls and 'high-scoring patients' with a PTSS-10 score greater than or equal to the cutoff score, indicating an increased risk for development of PTSD; bsignificant difference between healthy controls and 'low-scoring patients' with a PTSS-10 score below the cutoff score; csignificant difference between 'high-scoring patients' and 'low-scoring patients'.
