International meta-analysis of PTSD genome-wide association studies identifies sex- and ancestryspecific genetic risk loci

The risk of posttraumatic stress disorder (PTSD) following trauma is heritable, but robust common variants have yet to be identified. In a multi-ethnic cohort including over 30,000 PTSD cases and 170,000 controls we conduct a genome-wide association study of PTSD. We demonstrate SNP-based heritability estimates of 5–20%, varying by sex. Three genome-wide significant loci are identified, 2 in European and 1 in African-ancestry analyses. Analyses stratified by sex implicate 3 additional loci in men.

7ROSES, a transdiagnostic intervention for promoting self-efficacy in traumatized refugees : a first quantitative evaluation

Objective: Due to traumatic experiences and highly prevalent post-migration stressors, refugees are vulnerable for developing psychopathology. To date, research has mainly evaluated trauma-focused therapies, targeting post traumatic stresss symptoms. Treatments targeting post-migration stressors are relatively understudied. The present cohort study evaluated the potential effectiveness of 7ROSES, a transdiagnostic intervention that aims to increase self-efficacy among treatment-seeking refugees in dealing with postmigration stressors.

Undocumented asylum seekers with posttraumatic stress disorder in the Netherlands

Background: To date, most studies on the mental health of refugees in Europe have focused on the prevalence and treatment of psychopathology. Little is known about those who illegally reside in the host country, referred to, in the Netherlands, as undocumented asylum seekers. There are indications that mental health and psychosocial problems are more prevalent in this group than among refugees in general, with unsatisfactory treatment outcomes.

Increasing Family Safety and Decreasing Parental Stress and Child’s Social-Emotional Problems with Resolutions Approach : a Single-Case Experimental Design Study Protocol

The present study describes a Single-Case Experimental Design (SCED) research protocol. The outlined research is aimed at investigating the effectiveness and potential mechanisms of the Resolutions Approach (RA), a multidisciplinary intervention to stop child abuse and enhance safety in the families. Given the heterogeneity of the population and innovativeness of the topic, a SCED with a baseline period (A-phase) followed by a treatment period (B-phase) is designed.

The resilience framework as a strategy to combat stress-related disorders

Consistent failure over the past few decades to reduce the high prevalence of stress-related disorders has motivated a search for alternative research strategies. Resilience refers to the phenomenon of many people maintaining mental health despite exposure to psychological or physical adversity. Instead of aiming to understand the pathophysiology of stress-related disorders, resilience research focuses on protective mechanisms that shield people against the development of such disorders and tries to exploit its insights to improve treatment and, in particular, disease prevention.

Patterns of Recovery From Early Posttraumatic Stress Symptoms After a Preventive Intervention With Oxytocin : Hormonal Contraception Use Is a Prognostic Factor

In a previous issue of Biological Psychiatry, we reported on the efficacy of repeated intranasal oxytocin administration early after emergency department admission in preventing posttraumatic stress disorder (PTSD) symptoms, assessed 1.5, 3, and 6 months posttrauma (1). In a randomized, placebocontrolled trial, we demonstrated beneficial effects in patients with high symptom levels before treatment onset (1,2).

The Dissociative Subtype of PTSD Interview (DSP-I) : Development and Psychometric Properties

The inclusion of the dissociative subtype of post-traumatic stress disorder (PTSD-DS) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM–5) reflects the importance of assessing PTSD-DS. We developed the Dissociative Subtype of PTSD Interview (DSP-I).

Stronger Than My Ghosts : Narrative Exposure Therapy and Cognitive Recovery in Later Life

Background: To explore cognitive recovery during and after Narrative Exposure Therapy from the patient’s perspective, autobiographical material and interview responses were qualitatively
analyzed.

Method: Using a framework of cognitive development, patient-reported outcomes from four senior Dutch citizens (57–81 years of age) were examined. All participants reported multiple traumatic experiences, including adverse childhood experiences.

Randomised controlled trial comparing narrative exposure therapy with present-centred therapy for older patients with post-traumatic stress disorder

Background: Evidence-based treatment and age-specific services are required to address the needs of trauma-affected older populations. Narrative exposure therapy (NET) may present an appropriate treatment approach for this population since it provides prolonged exposure in a lifespan perspective. As yet, however, no trial on this intervention has been conducted with older adults from Western Europe.

Aims: Examining the efficacy of NET in a sample of older adults.

Expert medico-legal reports: The relationship between levels of consistency and judicial outcomes in asylum seekers in the Netherlands

Introduction: If asylum applicants need to prove that they have been persecuted in their home country, expert judgment of the psychological and physical consequences of torture may support the judicial process. Expert medico-legal reports can be used to assess whether the medical complaints of the asylum seeker are consistent with their asylum account. It is unclear which factors influence medical expert judgement about the consistency between an asylum seeker’s symptoms and story, and to what extent expert medico-legal reports are associated with judicial outcomes.
