BACKGROUND: The aim was to develop further a screening instrument for complex posttraumatic stress disorder (cPTSD). The screening for cPTSD (SkPTBS) tests a) potential traumatic experiences, b) influential features and risk factors, and c) symptoms of cPTSD. The SkPTBS by Dorr et al. (2016) was revised according to the current ICD-11 criteria set proposal for cPTSD and is explored in its revised edition. METHOD: Impacts of long-lasting interpersonal trauma were tested in inpatients of psychosomatic rehabilitation and in patients consulting a university outpatient center for trauma therapy...

Cognitive deficits in Posttraumatic Stress Disorder (PTSD) and dissociative symptoms suggest there may be an underlying and persistent problem with temporal processing in PTSD, but this question has not been systematically examined. We investigated the ability of a group of PTSD participants in estimating the duration of supra-second visual stimuli relative to healthy controls. The data of 59 participants with PTSD and 62 healthy controls, collected from the BRID database, have been examined. Overall, our results indicate that PTSD patients overestimate the duration of the displayed stimuli...

OBJECTIVES: Dissociation is a prevalent phenomenon among veterans with post-traumatic stress disorder (PTSD) that may interfere with the effectiveness of treatment. This study aimed to replicate findings of a dissociative PTSD subtype, to identify corresponding patterns in coping style, symptom type, and symptom severity, and to investigate its impact on post-traumatic symptom improvement. METHODS: Latent profile analysis (LPA) was applied to baseline data from 330 predominantly (97%) male treatment-seeking veterans (mean age 39...

This study aimed to ascertain the prevalence of different types of Religious/Ritual Abuse (RA) among Iranian young adults and to investigate the relationships between RA, childhood and recent trauma, and different patterns of dissociativity. A total of 100 male and 100 female university students completed and returned a 51-item questionnaire designed to detect the extent of dissociation, childhood and recent trauma history, and RA; 12.5% of participants reported history of RA. Pearson correlation analysis showed that RA strongly correlated with dissociativity...

Sexual assault and suicide are two serious public health concerns. Research has documented the relationship between sexual assault and suicidal thinking and attempts; however, limited research explores the more multifaceted relationships between posttraumatic stress reactions and suicidal ideation in college students through unsuccessful modulation of emotion. The authors hypothesized a mediation model where the relationship between sexual assault and suicidal ideation is mediated by dissociation and hostility...

Peritraumatic dissociation and distress are strong predictors of acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) development. However, there is limited data concerning gender differences in these relations, particularly among victims of violent crimes (VVC). The objective of this study is to examine whether peritraumatic dissociation and distress predict the number of ASD symptoms differently for men and women VVC. In all, 162 adults (97 women, M age = 39.6 years), 63% of whom experienced physical assaults, completed the Acute Stress Disorder Interview, the Peritraumatic Dissociative Experience Questionnaire, and the Peritraumatic Distress Inventory...

Posttraumatic stress disorder (PTSD) and traumatic brain injury (TBI) commonly co-occur in general and military populations and have a number of overlapping symptoms. While research suggests that TBI is risk factor for PTSD and that PTSD may mediate TBI-related outcomes, the mechanisms of these relationships are not well understood. Neuroimaging may help elucidate patterns of neurocircuitry both specific and common to PTSD and TBI and thus help define the nature of their interaction, refine diagnostic classification, and may potentially yield opportunities for targeted treatments...

OBJECTIVE: To examine the two constitutes of cortical volume (CV), that is, cortical thickness (CT) and surface area (SA), in individuals with dissociative identity disorder (DID) with the view of gaining important novel insights into the underlying neurobiological mechanisms mediating DID. METHODS: This study included 32 female patients with DID and 43 matched healthy controls. Between-group differences in CV, thickness, and SA, the degree of spatial overlap between differences in CT and SA, and their relative contribution to differences in regional CV were assessed using a novel spatially unbiased vertex-wise approach...

Child maltreatment (CM) in foster care settings (i.e., institutional abuse, IA) is known to have negative effects on adult survivor's mental health. This study examines and compares the extent of CM (physical, emotional, and sexual abuse; physical and emotional neglect) and lifetime traumatization with regard to current adult mental health in a group of survivors of IA and a comparison group from the community. Participants in the foster care group (n = 220) were adult survivors of IA in Viennese foster care institutions, the comparison group (n = 234) consisted of persons from the Viennese population...

OBJECTIVE: Complex posttraumatic stress disorder (CPTSD) is a newly proposed diagnosis in the International Classification of Diseases-version 11, which is currently intensively investigated. Childhood trauma is regarded as main source of CPTSD symptoms, even in later life. Induction of DNA methylation changes by childhood trauma may contribute to its long-lasting adverse health consequences. The current study analyzed the correlation of genome-wide DNA methylation profiles with complex posttraumatic sequelae in buccal epithelial cells from 31 elderly former indentured child laborers (Verdingkinder) using the Infinium Illumina 450k Human DNA methylation chip...

Microelectrode arrays (MEAs) are innovative tools used to perform electrophysiological experiments for the study of electrical activity and connectivity in populations of neurons from dissociated cultures. Reliance upon neurons derived from embryonic tissue is a common limitation of neuronal/MEA hybrid systems and perhaps of neuroscience research in general, and the use of adult neurons could model fully functional in vivo parameters more closely. Spontaneous network activity was concurrently recorded from both embryonic and adult rat neurons cultured on MEAs for up to 10 weeks in vitro to characterize the synaptic connections between cell types...

In 2015, a large number of refugees arrived in Germany, mostly driven to emigrate by devastating circumstances in their countries of origin. Arriving refugees are distributed to reception centers within the German federal states, frequently facing marginal conditions in terms of overcrowding or waiting time of several months until their application for asylum is processed. Most of these refugees underwent numerous traumatizing experiences-both in their country of origin and while fleeing from their country of origin...

Background: Among adults there is strong evidence about peritraumatic dissociation (PD) predicting posttraumatic stress disorder (PTSD), yet evidence among children is very limited. It has been suggested that disturbances in memory functioning might explain the association between PD and PTSD, but this has not yet been empirically tested. Objective: We aimed to test the hypotheses that greater PD would be associated with more posttraumatic stress disorder (PTSD) symptoms, and that some of this association would be mediated by disorganized and non-verbal memories about the traumatic event...

BACKGROUND: Nonsuicidal self-injury (NSSI) is a key feature of borderline personality disorder (BPD), which is strongly associated with childhood traumatization. To the best of our knowledge, there has been a lack of studies investigating extensively the characteristics of borderline patients who engage in extremely high numbers of NSSI, and their features of NSSI, trauma history and psychopathology. The aim of this study is to identify groups of borderline inpatients on the basis of the lifetime number of NSSI, and to explore the characteristics of these groups regarding the onset, reasons and methods of NSSI, history of childhood traumatization, and severity of psychopathology...

The present study examined the relationship between peritraumatic reactions, posttraumatic stress disorder (PTSD) symptoms, somatization, and quality of life (QoL) in a sample of refugees, two years after the 2011 Ivory Coast sociopolitical crisis. Participants were 101 Ivorian adult refugees (mean age = 31.61 years, SD = 7.84; 45.5% women) who completed several questionnaires relating to peritraumatic reactions, PTSD symptoms, somatization, and QoL. Most participants (86.1%) scored above the cutoff for probable PTSD...

Adverse childhood experiences have a strong negative impact on health and are a significant public health concern. Adverse childhood experiences, including various forms of child maltreatment, together with their mental health sequelae (eg, posttraumatic stress disorder, depression, dissociation) also contribute to adverse pregnancy outcomes (eg, preterm birth, low birth weight), poor postpartum mental health, and impaired or delayed bonding. Intergenerational patterns of maltreatment and mental health disorders have been reported that could be addressed in the childbearing year...

OBJECTIVE: The objective of the study was to determine whether male and female populations of patients with psychogenic nonepileptic seizures (PNES) differ, in terms of demographic, social/clinical, and etiological factors as well as psychological measures. BACKGROUND: Psychogenic nonepileptic seizures are overrepresented by females; therefore, information about PNES in males is limited. Only a handful of studies have examined PNES and gender, and of those, one was a literature review and with the exception of two, most have had small sample sizes...

Posttraumatic stress disorder (PTSD) is commonly acknowledged to be associated with reduced specificity of autobiographical memory (AM). However, very few studies have assessed AM in the peritraumatic phase. The aim of the present study was to examine whether the AM impairment reported in PTSD is present a few days after a traumatic event. We assessed AM in 41 participants who had recently been exposed to trauma, and 34 controls who had never experienced a traumatic situation. The trauma-exposed participants also completed the Impact of Event Scale-R (IES-R), the Inventory of Peritraumatic Distress, and the Peritraumatic Dissociative Experiences Questionnaire...

OBJECTIVE: The purpose of this study was to examine the co-occurrence of posttraumatic stress disorder (PTSD) and dissociation in a clinical sample of trauma-exposed adolescents by evaluating evidence for the depersonalization/derealization dissociative subtype of PTSD as defined by the DSM-5 and then examining a broader set of dissociation symptoms. METHOD: A sample of treatment-seeking, trauma-exposed adolescents 12 to 16 years old (N = 3,081) from the National Child Traumatic Stress Network Core Data Set was used to meet the study objectives...

BACKGROUND: A Dissociative Subtype of Posttraumatic Stress Disorder (PTSD) was added to the DSM-5, but little is known about this symptom pattern in young children exposed to trauma. Tailoring treatment to traumatized young children requires understanding the different patterns of trauma-related symptomatology and important correlates. The current study tested the hypothesis that type and number of child traumatic events, caregiver trauma exposure, and caregiver symptomatology would predict whether traumatized young children presented with PTSD, PTSD with clinical dissociation, or non-clinical trauma symptoms...
