Orted exposure to a traumatic event with indication of a certain known index trauma. A total of 42 patients (6.five ) had much more than 20 missing data on the selected combination of variables and had been excluded in the analyses. The final sample in the Pain Center for that reason comprised 608 participants (32.1 males, M age = 50.46 years, SD = 13.93, range 188), of whom 219 indicated targeted traffic or workrelated accidents because the index trauma. There were a limited amount of missing information (0.9.0 ) missing entirely at random [Little’s MCAR test two(9318) = 9367.28, p = .357]. The estimated PTSD prevalence prices according to the diagnostic criteria for the PCL5 had been 25.three (n = 143) within the full sample and 22.3 (n = 45) in the website traffic and workrelated accident subsample.1219019-23-4 Chemscene Probably the most prevalent sorts of traumatic exposure reported because the index trauma in the complete sample were traffic or workrelated accident (36.0 , n = 219), lifethreatening illness (25.0 , n = 152), sudden accidental death (24.eight , n = 151), assault (9.7 , n = 59), violence (four.three , n = 26), and disaster (0.2 , n = 1). To investigate the initial objective, individuals from the Pain Center reporting an index trauma associated to targeted traffic or workrelated accidents have been consecutively invited to take part in a diagnostic interview (n = 38, 55.3 males, M age = 44.8 years, SD = 11.1, variety = 223). In addition, patients with chronic whiplashrelated pain meeting the diagnostic criteria for PTSD measured by the CAPS5 from a rehabilitation hospital (n = 46, 30.four males, M age = 35.9 years, SD = 11.0, variety = 2063) had been incorporated, leaving an eligible sample for the initial objective size of 84. Of note, there were no missing data within the subsample from the Pain Center; however, the sample in the rehabilitation hospital originally consisted of 54 participants, of whom eight had been excluded owing to missing items around the PCL5, leaving a subsample of 46 participants to become applied in this study. two.two. Process For the Discomfort Center information set, information have been collected from patients who have been referred to assessment and treatment in the University Hospital Interdisciplinary Discomfort Center, Odense, Denmark, in the course of 2018. All referred individuals have been invited to participate in an electronic questionnaire survey (Clinical Pain Registry, PainData) just before the initial consultation at the discomfort clinic. The questionnaire wasM. HANSEN ET AL.Table 1.
