Aims To assess the factorial validity and internal reliability of the International Trauma Questionnaire (ITQ) among a treatment-seeking sample of survivors of sexual violence in Ireland. In addition, to assess the diagnostic rate of post-traumatic stress disorder (PTSD) and complex post-traumatic stress disorder (CPTSD) among the samples. Methods...

Purpose of Review The aim of this review article is to give an overview over recent experimental neurobiological research on dissociation in borderline personality disorder (BPD), in order to inform clinicians and to stimulate further research. First, we introduce basic definitions and models that conceptualize dissociation from a transdiagnostic p...

The present systematic review examined post-migration variables impacting upon mental health outcomes among asylum-seeking and refugee populations in Europe. It focuses on the effects of post-settlement stressors (including length of asylum process and duration of stay, residency status and social integration) and their impact upon post-traumatic s...

Background: Despite concerns of conceptual similarity, increasing evidence supports the discriminant validity of Complex Posttraumatic Stress Disorder (CPTSD) and Borderline Personality Disorder (BPD). However, all studies to date have assumed a categorical model of psychopathology. In contrast, dimensional models of psychopathology, such as the Hi...

Background: Co-occurrence of psychosis and posttraumatic stress disorder (PTSD) symptoms has been demonstrated, but the ICD-11 marks a significant divergence in the formulation of PTSD with a focus on the core symptoms and the addition of complex PTSD (CPTSD). Objective: To evaluate the distribution of psychosis and traumatic stress symptoms using...

Background: Theoretical accounts and empirical evidence have underlined the commonalities in phenomenology and aetiology of posttraumatic symptomatology and symptoms of psychosis (Morrison, Frame & Larkin, 2003; Shevlin et al., 2011), but investigation of this relationship under the ICD-11 conceptualization of trauma-related disorders is lacking. O...

Objective: This study investigated the latent dimensional and categorical structure of ICD-11 complex posttraumatic stress disorder (CPTSD) within a refugee sample. Method: A subsample that identified as refugee (n = 308) was selected from the National Epidemiological Survey on Alcohol and Related Conditions. Factor mixture modeling (FMM) was em...

Introduction There has been debate regarding whether Complex PTSD (CPTSD) is conceptually distinct from Borderline Personality Disorder (BPD). Objective To assess whether ICD-11 CPTSD was distinguishable from BPD in a sample of sexual assault survivors. Method A subsample of individuals (n = 956), that selected sexual assault as an index trauma,...

In this paper we present a description of a new, Horizon2020, Marie Curie Sklodowska Action funded, research and training program called CONTEXT, or the ‘COllaborative Network for Training and EXcellence in psychoTraumatology’. The three objectives of the program are put forward, each of which refers to a key component of the CONTEXT program. First...

Dissociation involves disruptions of usually integrated functions of consciousness, perception, memory, identity, and affect (e.g., depersonalization, derealization, numbing, amnesia, and analgesia). While the precise neurobiological underpinnings of dissociation remain elusive, neuroimaging studies in disorders, characterized by high dissociation...
