Assessment of trauma and its consequences

Theme leader: Miranda Olff

The Global Collaboration on Traumatic Stress recognized there was no instrument available for screening of the wide range of potential outcomes of trauma for trauma survivors around the world in different cultures.  This resulted in the development of the Global Psychotrauma Screen (GPS). 

The group further focused on the validation of the Computerized Childhood Attachment and Relational Trauma Screen (CARTS), a self-report measure designed to measure occurrences of childhood maltreatment, and its translation into multiple languages. 

The global population is growing older and ageism takes place. Older adults and people with dementia may have a different symptom presentation of PTSD compared to adults (ON TRACK and TRADE).

Forcibly displaced persons
Theme leader: Anke Witteveen
Sunset Soccer

There are currently over 70 million forcibly displaced persons worldwide, with more than 29 million of these being refugees and asylum-seekers (UNHCR, 2019). Rates of psychological disorders are elevated amongst individuals from a refugee background. It is critical that rigorous research be conducted to understand the factors that influence mental health in refugees and asylum-seekers. The development of an evidence base relating these factors will directly inform policies and practices to support individuals who have been exposed to persecution and displacement.

Projects are currently being developed to address this theme.

Global prevalence of stress and trauma related disorders 
Theme leader: Carolina Salgado
Aarde G-stress_edited.png

Approximately 70% of the world’s population have been exposed to a traumatic life event, and the resulting mental health problems represent a major challenge to public mental health services, globally. 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. 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). ...  Read more

Socio-emotional development across cultures
Theme leader: Monique Pfaltz
Picture theme Emotion Regulation- Moniqu

Childhood maltreatment (abuse and neglect) has long-term effects on mental and physical health. It also negatively impacts social functioning, which, in turn, is closely linked to health and well-being. Projects under this topic will mainly use experimental methods to assess cognitive, behavioral, physiological and emotional aspects of social functioning and interpersonal interactions. The aim of these projects is to identify factors that underlie healthy (e.g. satisfying close relationships) and impaired social functioning (e.g. difficulties with setting boundaries, regulating closeness and distance, or processing and interpreting non-verbal interpersonal signals like facial expressions) in those affected by childhood maltreatment. Findings shall provide a basis for the development of interventions improving social functioning and thus health and well-being.

Collaborating to make traumatic stress research data “FAIR”
Theme leader: Nancy Kassam-Adams

The FAIR Guiding Principles for scientific data stewardship state that data should be Findable, Accessible, Inter-operable, and Re-usable (FAIR). These principles are part of the growing movement toward more open and transparent science.  Making traumatic stress research data more FAIR can promote better science, enhance understanding of trauma impact and recovery, and ultimately benefit trauma-exposed individuals and communities around the world.  But to date most traumatic stress studies have not been designed with data preservation, sharing, or re-use in mind.  Projects in this theme will create resources that can facilitate FAIR data across the field of traumatic stress studies.

Global crises
Theme leaders: Sara Freedman and Tatiana Davidson

Global COVID-19-related traumatic stress activities

The COVID-19 outbreak is a global problem, an unprecedented pandemic, a public health emergency of international concern that threatens lives and well-being of the world population. It is also affecting health care professionals on the front lines, as well as mental health professionals providing psychosocial support. 

As the COVID-19 outbreak is a global problem, it also requires a global solution. Therefore, global collaborating is vital, i.e. working together on COVID-19-related traumatic stress aspects (policies, best practices and research).

We will need to address how people may respond differently to the crisis around the world, how to best communicate about the outbreak and its consequences - taking culture, gender and age aspects into account - how to provide peer support to health workers or other affected professionals, and what are (online) interventions that are needed at a later stage.


A large range of project focus on COVID-19 in different settings, details to be found on the project pages.

Treatments across cultures
Theme leader: Debra Kaysen
Interventions and treatments for trauma-related disorders across cultures

Trauma is not limited by national borders. In addition, from a global perspective, exposure to one or more traumatic events is the norm rather than the exception. Importantly, in spite of a lot of overlap and commonalities, traumatic experiences, trauma-related symptoms, as well as treatment approaches differ across geographic regions and cultures.

The Global Collaboration is currently initiating projects with the aim of generating and disseminating more in-depth knowledge about the cultural aspects of trauma and its psychological, physical and social consequences as well as their treatment.
