This letter provides an update on the activities of “The Global Collaboration on Traumatic Stress” (GC-TS) as first described by Schnyder et al. in 2017. It presents in further detail the projects of the first theme, in particular the development of and initial data on the Global Psychotrauma Screen (GPS), a brief instrument designed to screen for the wide range of potential outcomes of trauma.

Objectives
Little is known about the 12-month prevalence of potentially traumatic events (PTEs) and to what extent the type of PTE is a risk factor for post-event lack of social support. In addition, it is largely unknown if pre-event mental health problems and loneliness, and demographics are risk factors for a lack of support. Aim of the present prospective study is to fill these gaps in evidence-based knowledge.
 

In deze eeuw zijn in de psychiatrie nauwelijks nieuwe geneesmiddelen beschikbaar gekomen en ook in de psychotherapie bouwt men voort op innovaties uit het verleden. Op zoek naar effectieve interventies bij therapieresistente depressie, posttraumatische stressstoornis (PTSS) en verslaving wordt nu de waarde onderzocht van middelen als ketamine, psilocybine en MDMA, vaak in combinatie met psychotherapie. Een rondgang langs enkele wetenschappelijke initiatieven.

Objective
To explore the potential efficacy of multi-modular motion-assisted memory desensitisation and reprocessing (3MDR) in British military veterans with treatment-resistant, service-related PTSD.
 

Methods
Exploratory single-blind, randomised, parallel arm, cross-over controlled trial with nested process evaluation to assess fidelity, adherence and factors that influence outcome.
 

De 88-jarige Ank Reinders wil graag haar oorlogsverhaal en dat van haar moeder vertellen omdat die haar altijd beschermd heeft in de Japanse interneringskampen Solo en Moentilan op Java. Na de oorlog zaten Ank en haar moeder in de opvangkampen Soerabaja en Singapore. Zij vertrokken vanuit Singapore naar Nederland. Vlak na de oorlog ging haar moeder als verpleegster naar Nederlands-Indië om gewonde Nederlandse militaire te verplegen. 

Background
Depression is often reported as co-occurring with post-traumatic stress disorder in children and adolescents, but its prevalence within trauma-exposed child and adolescent samples is not well understood.

There is a need in the global south to evaluate and implement empirically supported psychological interventions to ameliorate symptoms of posttraumatic stress disorder (PTSD). Empirically supported treatments (ESTs) have increasingly been developed and implemented, yet the majority people in the global south do not have access to these treatments for mental disorders such as PTSD. Prolonged exposure therapy has accrued substantial empirical evidence to show it as an effective treatment for PTSD.

Background: Caregivers play a key role in the success of trauma-focused cognitive behavioural therapy (TF-CBT). Yet, the effect of their alliance on treatment outcomes besides the
other parties in treatment has hardly been studied.
Objective: This study examined the working alliance (WA) of therapists, patients and caregivers in TF-CBT and its contribution on treatment outcome over time.

Background: any patients with post-traumatic stress disorder (PTSD) experience dissociative symptoms. The question of whether these dissociative symptoms negatively influence the effectiveness of psychotherapy for PTSD is unresolved.

Aims: To determine the influence of dissociative symptoms on psychotherapy outcome in PTSD.

Objective
Investigating the influence of the sequence in which two evidence-based trauma-focused treatments are offered to PTSD-patients.

Methods
PTSD-patients were treated using an intensive eight-day treatment program, combining Prolonged Exposure (PE) and EMDR therapy. Forty-four patients received a PE session in the morning and an EMDR session in the afternoon, while 62 patients received the reversed sequence (EMDR followed by PE). Outcome measures were PTSD symptom severity and subjective experiences.
