“…The first aim of the presented study was to compare the current PTSD symptom structure proposed in DSM-5 based on King et al’s model [8] with the most supported four-, five-, six- and seven-factor models proposed respectively by Simms et al [9], Elhai et al [10], Zawadzki et al [11], Liu et al [12] and Armour et al [14]. Afterwards we checked the structure of PTSD symptoms according to the ICD-11 proposal of core PTSD symptoms.…”

“…In total 1491 individuals who had not previously been clinically diagnosed, divided into two samples, participated in the study. Sample A participated in a pilot study for the PDS-5 scale [11], while sample B consisted of volunteers screened for PTSD (psychiatric examination) in a treatment study. Because 159 people did not indicate any traumatic event listed in the PDS-5 and 73 people incompletely answered items assessing PTSD symptoms, an effective sample of 1259 persons remained.…”

“…Participants completed the Polish version of the Posttraumatic Diagnostic Scale for DSM-5 (PDS-5) developed by Foa et al [39] (see Zawadzki et al [11]). The PDS-5 consists of a list of traumatic events, 20 items assessing symptoms of PTSD according to the DSM-5 criteria, and two items measuring the level of distress experienced by individuals, the level of influence the symptoms have on everyday functioning, and two items referring to the symptoms’ onset and duration.…”

Subjects from sample B1 were investigated from 1 month to 2 years after a serious MVA involving causalities (injuries or deaths), and subjects from sample B3 about four years after the flood experience involving loss of life and massive material losses.…”

“…In our previous research within diverse trauma populations we examined the fit of most popular models, finding the strongest empirical support for the “negative cognitions and numbing” model, which bases on the model proposed by Elhai et al [10], with additional factor for cognitive and mood changes [11]. Recently three new models were presented:…”

The structure of PTSD symptoms according to DSM-5 and IDC-11 proposal: A multi-sample analysis

Posttraumatic stress disorder (PTSD) symptoms structure is a subject of ongoing debate since its inclusion in DSM-III classification in 1980. Different research on PTSD symptoms structure proved the better fit of four-factor and five-factor models comparing to the one proposed by DSM-IV. With the publication of DSM-5 classification, which introduced significant changes to PTSD diagnosis, the question arises about the adequacy of the proposed criteria to the real structure of disorder symptoms. Recent analyses suggest that seven-factor hybrid model is the best reflection of symptoms structure proposed to date. At the same time, some researchers and ICD-11 classification postulate a simplification of PTSD diagnosis restricting it to only three core criteria and adding additional diagnostic unit of complex-PTSD. This research aimed at checking symptoms' structure according to well-known and supported four-, five-, six- and seven-factor models based on DSM-5 symptoms and the conceptualization proposed by the ICD-11 as well as examining the relation between PTSD symptoms categories with borderline personality disorder. Four different trauma populations were examined with self-reported Posttraumatic Diagnostic Scale for DSM-5 (PDS-5) measure. The results suggest that six- and seven-factor hybrid model as well as three-factor ICD-11 concept fits the data better than other models. The core PTSD symptoms were less related to borderline personality disorder than other, broader, symptoms categories only in one sample. Combination of ICD-11 simplified PTSD diagnosis with the more complex approach (e.g. basing on a seven-factor model) may be an attractive proposal for both scientists and practitioners, however does not necessarily lower its comorbidity with borderline personality disorder.
