1. G-Stress
A global assessment of the ICD-11 stress-related disorders
Project group
See Core collaborators and Collaborators below.
This project brings together traumatic stress experts from around the world including members of ISTSS, ESTSS, and DeGPT. Four of the collaborators are also part of the other Global Collaboration projects who such as the development of the Global Psychotrauma Screen (GPS), the e-pamphlets for adults who have experienced childhood trauma (Internet information on Childhood Abuse and Neglect ((iCAN)) the the CARTS project (ongoing).

Background
Approximately 70% of the world’s population have been exposed to a traumatic life event (Benjet et al., 2016, Kessler et al., 2017), and the resulting mental health problems represent a major challenge to public mental health services, globally (Sara & Lappin, 2017). In 2018, the World Health Organization (WHO) released the 11th version of the International Classification of Diseases (ICD-11), the primary diagnostic manual used by health professionals worldwide (First, Reed, Hyman, & Saxena, 2015). All United Nations member states are committed to using the ICD-11, and relevant to psychotraumatologists, ICD-11 provides novel descriptions of stress-related psychopathology compared to the ICD-10 and the DSM-5 (American Psychiatric Association, 2013).
Under the parent category of ‘Disorders Specifically Associated with Stress’, ICD-11 defines a number of stress-related disorders including ‘Posttraumatic Stress Disorder’ (PTSD) (PB40), ‘Complex PTSD’ (CPTSD) (PB41), ‘Prolonged Grief Disorder’ (PB42), and ‘Adjustment Disorder’ (PB43). The guiding principles underlying the development on these disorders were that they should (a) maximize clinical utility by including a small number of core symptoms and (b) be internationally applicable (Maercker et al., 2013). The World Mental Health Survey consortium have provided information about the prevalence of traumatic life events, and PTSD, internationally (Benjet et al., 2016; Karam et al., 2014). While valuable, these studies utilized the now outdated DSM-IV description of PTSD.
Aims
As ICD-11 represents the primary diagnostic manual used worldwide, and includes a new and distinct model of stress-related psychopathology, it is imperative for psychotraumatology research and practice to determine the global prevalence rates of these disorders.
Methods and Output
Members of the G-Stress Project have begun to assess the current prevalence rates of the ICD-11 stress-related disorders using nationally representative samples in countries like Israel (Hyland et al., under review; Kilkelly et al., 2019), Germany (Maercker et al., 2018), United Kingdom (Maercker et al., 2018; Cloitre et al., 2018) and United States (Cloitre et al., in press). It is clear that substantially more data is needed from nations all around the world to better understand how common these disorders are. In this project, we invite members of the ISTSS’s Global Collaboration to contribute to the ongoing work that aims to ascertain the prevalence of the ICD-11 stress-related disorders around the world. By obtaining information about the prevalence rates of the ICD-11 stress-related disorder at a global level, the ISTSS’s Global Collaboration will be able to provide the scientific community with vital information about the frequency and distribution of stress- and trauma-related events, and stress-related disorders, globally. This would allow for more effective and efficient resource planning among global health professionals.
The following countries have already collected data:
· United Kingdom
· United States of America
· Israel
· Ghana, Kenya, and Nigeria
· Germany
· Ukraine
· Lithuania
· Ireland

Currently looking for collabroators, pleae contact the project leader if interested
Background
Sexual violence, whether perpetrated by armed forces, strangers or partners, is prevalent worldwide and has far-reaching repercussions for victims. Despite increased attention for victims it is remarkable that an important issue remains unaddressed, namely Sexual Violence Related Pregnancies (SVRP).
Even though gender-based violence is of all times and ages, the exact prevalence of pregnancies or deliveries as a result of sexual violence is until today unknown. It is estimated that 5% of sexual violence victims become pregnant, however, outcomes of SVRPs and related wellbeing among women may differ over countries as the social environment differs. It is precisely this, an understanding of the relation between SVRP and wellbeing of women (and children) by developing a theory of change model of relational and societal factors of risk and resilience, that is achieved by this project.
The proposed project consists of two steps. First, to analyze the unique experience that acknowledges the complexity of the individual experience of these women dimensions of individual, relational and societal consequences and their relation to wellbeing will be explored qualitatively thereby creating a broader picture of protective and risk factors that may be of importance. In step two a descriptive cohort study over countries will be set up.
Aims
This project aims to improve the formal and informal support given to women when needed, firstly by generating an open discussion, secondly by an understanding of the mechanisms that contribute to their difficulties, and thirdly by an understanding of the support needed.
Method
To analyze the unique experience that acknowledges the complexity of the individual experience of these women. Dimensions of individual, relational and societal consequences and wellbeing will be explored qualitatively, thereby generating rich data and creating a broader picture of protective and risk factors that may be of importance. To explore retrospectively women’s experience questions will be asked about, the process of choices, involved social network, norms and values, belonging, trust, factors of risk and resilience, given social support (positive and negative), needed type of support (formal and informal), experienced (self-)stigma, wellbeing, and changes throughout the process.
