“…Each item is scored on a 4-point scale of symptom frequency, with higher scores indicating greater symptom severity. The Japanese version of PDS has demonstrated good reliability and validity 59,63 . We administered Parts 1 & 2 to all participants in order to determine the presence/absence of traumatic experiences, and if present, Parts 3 & 4 were administered for the assessment of diagnosis and severity of PTSD.…”

Individuals with posttraumatic stress disorder (PTSD) show low resilience and impaired quality of life (QOL). Accumulating evidence shows that PTSD is associated with increased inflammation. Studies suggest that inflammation can be a key mechanism underlying low resilience/QOL, but this relationship has been understudied in individuals with PTSD. Here, we investigated the association of blood proinflammatory markers with self-reported resilience and QOL in civilian women with PTSD. Fifty-six women with PTSD and 73 healthy control women participated in this study. Resilience was assessed using the Connor-Davidson Resilience Scale. QOL was assessed using the World Health Organization Quality of Life-BREF. Blood samples were collected for the measurement of three proinflammatory markers including interleukin-6 (IL-6), high-sensitivity tumor necrosis factor-α, and high-sensitivity C-reactive protein (hsCRP). Compared to controls, patients showed significantly higher IL-6 levels and lower resilience and QOL. In patients, IL-6 levels were significantly negatively correlated with resilience, and hsCRP levels were significantly negatively correlated with psychological QOL. These results show that increased levels of proinflammatory markers including IL-6 and hsCRP are associated with lower psychological resilience and QOL in PTSD patients. Our findings suggest that interventions and treatments targeting inflammation may aid in the recovery from PTSD and lead to better prognosis.

“…We used data from the PDS and CAPS collected in our previous study (Itoh et al, 2017) with clinical and non-clinical samples ( N = 225). The data were screened and excluded if (1) the complete item data were not accessible ( n = 3) or (2) there was no listed traumatic event in the checklist on Part 1 of the PDS ( n = 53, nearly half of the non-clinical sample).…”

“…The Japanese version (Itoh et al, 2017) was used in this study; its validity is high (AUC of .97 against the CAPS diagnosis, the sensitivity of 97.0%, and specificity of 93.6%). The PDS comprises four parts assessing traumatic experiences (Part 1 and 2), symptom severity over the past month corresponding to Criteria B–D of the DSM-IV (Part 3), and functional disorder (Part 4).…”

“…We compared 2- and 3-item versions of the new re-experiencing scales, because a screening scale can never be too short in terms of reducing the burden on respondents, but longer scales can increase the likelihood of correctly identifying the concept of concern. We used the PDS to develop a short scale because it has as high validity as other self-rating scales such as the PCL (Adkins, Weathers, McDevitt-Murphy, & Daniels, 2008), corresponds to the DSM criteria for PTSD, and has been validated in Japanese (Itoh et al, 2017). …”

Background: Identifying high-risk groups for posttraumatic stress disorder (PTSD) during evacuation situations requires a valid short screening tool. The re-experiencing symptoms of PTSD are considered helpful for distinguishing those with PTSD from those without, as they are thought to be specific to PTSD, have less ambiguity for respondents, and are representative of all PTSD symptoms. Objective: To develop a new short version of the Posttraumatic Diagnostic Scale (PDS) comprising only re-experiencing symptom items. Method: We used existing data (N = 169) from our previous study on the Japanese version of the PDS and the Clinician-Administered PTSD Scale (CAPS). The sample included both clinical outpatients (n = 106) and university students (n = 63), all of whom reported one or more traumatic experiences. We created candidate 2- and 3-item versions of the PDS and compared their psychometric characteristics against the CAPS. Results: The best candidate (comprising items for ‘intrusive images’, ‘nightmares’, and ‘physiological reactions when reminded of the trauma’) demonstrated an area under the curve of .95, 94.8% sensitivity, 86.1% specificity for the best cut-off score of three. The candidate scale also showed a strong correlation with CAPS-evaluated severity score and internal consistency. Conclusions: The brief re-experiencing PDS had good psychometric properties among Japanese adults with and without PTSD.

“…In the present study, we administered Parts 1 & 2 to all participants for the assessment of presence/absence of traumatic experiences and Parts 3 & 4 to only patients for the assessment of PTSD diagnosis. We have previously shown that the PTSD diagnosis concordance rate between the PDS and the Clinician-Administered PTSD Scale (22), a structured interview for the diagnosis of PTSD, was very high (95.1%, k = 0.90) (23).…”

Possible Long-Term Effects of Childhood Maltreatment on Cognitive Function in Adult Women With Posttraumatic Stress Disorder

Accumulated evidence shows that individuals with posttraumatic stress disorder (PTSD) have compromised cognitive function. PTSD is associated with childhood maltreatment, which also can negatively affect cognitive function. It is therefore possible that cognitive dysfunction in adult patients with PTSD can be due at least partly to childhood maltreatment, although little is documented on this issue. Here we aimed to examine the possible effect of childhood maltreatment on cognitive function in adult patients with PTSD. A total of 50 women with DSM-IV PTSD and 94 healthy control women were enrolled. Most of the patients developed PTSD after experiencing interpersonal violence during adulthood. History of childhood maltreatment was assessed using the Childhood Trauma Questionnaire (CTQ). Cognitive functions were assessed by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Compared to controls, patients reported significantly more experiences of all types of childhood maltreatment as assessed by the CTQ and showed significantly poorer performance on immediate memory, language, attention, and the total score of RBANS. In patients, sexual abuse scores were significantly negatively correlated with RBANS language (p < 0.001) and total score (p = 0.005). Further analyses revealed that PTSD patients with childhood sexual abuse had even poorer cognitive function than those without the abuse. In controls, no significant correlation was found between CTQ and RBANS scores. These results suggest that childhood maltreatment, specifically sexual abuse, may lead to persistent cognitive impairment in individuals with PTSD. Our findings might underscore the importance of early detection and intervention of childhood maltreatment, which will be achieved by careful observation of, and listening to, maltreated children in education and welfare scenes as well as clinical settings.
