2. Traumatic Stress and Adversity Faced by COVID-19 Frontline Healthcare Workers - A Text Mining Approach (C19-Text)

Project leader:  Julian Ford (

Project group: Miranda Olff, Cherie Armour, Jon Elhai, Davide Marengo, Marit Sijbrandij, Katharina Schultebraucks

Aims and method

Healthcare professionals and workers are exposed to many potentially traumatic threats and losses when caring for COVID-19 patients. Social and news media provide a channel for the general public to communicate with and about COVID-19 healthcare providers and for healthcare providers to communicate with each other and with their communities.

Text mining procedures with large news and social media databases internationally will be used to perform qualitative and machine learning analyses to identify and quantify major themes of the stressors and protective factors experienced by COVID-19 healthcare providers and correlate these with regional and national data on COVID-19 incidence and deaths, health system capacities and responses, and socioeconomic and ethnocultural factors. The aim is to refine the traumatic stress field’s knowledge of and interventions for the unique traumatic and related socioeconomic and ethnocultural stressors and protective factors facing COVID-19 healthcare providers.

3. Stressors, coping and symptoms of adjustment disorder in the course of the COVID-19 pandemic 

Project leaders: Annett Lotzin ( & Ingo Schäfer on behalf of ESTSS

Project group members: Helene Flood Aakvaag, Elena Acquarini, Dean Ajdukovic, Vittoria Ardino, Maria Böttche, Kristina Bondjers, Maria Bragesjö, Małgorzata Dragan, Piotr Grajewski, Margarida Figueiredo-Braga, Odeta Gelezelyte, Jana Darejan Javakhishvili, Evaldas Kazlauskas, Matthias Knefel, Brigitte Lueger-Schuster, Nino Makhashvili, Trudy Mooren, Luisa Sales, and Aleksandra Stevanovic. Please contact Annett Lotzin if you are interested in joining the study.


Aims and method

The primary aim of this longitudinal cohort study launched by the European Society of Traumatic Stress Studies (ESTSS) is to examine the relationships between risk and resilience factors, stressors and adjustment disorder symptoms during the pandemic, and to investigate whether these relationships are moderated by coping behaviors. All data will be assessed by an online-questionnaire longitudinally, with an interval of six months. Following a conceptual framework based on the WHO’s social framework of health, an assessment of individual and country-level risk and resilience factors, COVID-19 related stressors and pandemic-specific coping behavior will be measured to estimate their contribution to symptoms of adverse adjustment. As primary measure, adjustment disorder symptoms will be assessed (ADNM-8). Posttraumatic stress disorder symptoms (PC-PTSD-5) will be measured as a secondary measure. At present, eleven countries are participating in this study.

4. High-risk occupational groups responding to the COVID-19 pandemic

Project leaders: Talya Greene, Jo Billings, Michael Bloomfield

Project members: tbd


Aims and method

It is essential that the psychological response to the COVID-19 outbreak is coordinated, trauma-informed and evidence-based. This project aims to collate and develop globally transferable guidance for the psychosocial support of high-risk occupational groups responding to the COVID-19 pandemic. These groups include healthcare workers (e.g., doctors, nurses, technicians, porters, paramedics, hospital administrators), other essential workers (e.g., social workers, care home staff, cleaners, delivery workers), and their family members. Guidance should be evidence-based and is focused on which interventions are likely to be helpful, and which may be harmful, in coping with peritraumatic stress exposure, and mitigating long-term trauma reactions.

5. Posttraumatic adjustment in nurses

Project leader: Prof Dr Judith Daniels (

Project group: Judith Daniels, Astrid Lampe, Birgit Kleim, and others. Please contact Dr Daniels if interested to join.


Aims and method

Nurses are at the frontline of the current pandemic. They often have to handle emotionally impactful situations and at times make decisions that are against their moral judgements. We will assess the impact this has on their mental health and how the adjust following the peak of the crisis

It will be longitudinal online study with 3 assessment time points: after the local peak in Covid cases, 3 months later, and 6 months later.

Ideally, all nurses of the clinic would receive the invitation via their work email. We will have control groups (nurses in maternity etc) to compare to nurses in ICU/oncology etc. The questionnaire will take approx. 15 minutes per time point.

6. REACH for Mental Health

Project leaders: Amantia Ametaj, Archana Basu, Karmel Choi, Christy Denckla, Bizu Gelaye, Shaili Jha, Karestan Koenen, Kristina Korte

Please contact: Shaili Jha  ( if interested to join.

Aims and method

The mission of the REACH project is to bring evidence-based skills on managing stress and enhancing resilience to everyone around the world. This coordinated effort to “Do the Five for Mental Health” in the COVID-19 pandemic is summarized by the acronym REACH, which stands for 'Recognize the Problem', 'Expand the Social Safety Net', 'Assist Those Most at Risk', 'Cultivate Resilience', and 'Have Empathy.' One example of this initiative is the COVID-19 Mental Health Forums offered through the Harvard T.H. Chan School of Public Health designed to: 1) introduce evidence-based skills for managing stress related to the coronavirus (COVID-19) outbreak; and 2) provide techniques for adapting and enhancing resilience. Each week, Dr. Karestan Koenen and colleagues host international experts in the field of clinical psychology and trauma epidemiology research to address important emotional, psychological, and physical health issues related to daily life during a pandemic. These forums are global in focus, hosting for example African psychiatrists covering issues facing sub-Saharan Africa at this time. These forums are always open to the global public and include a discussion and Q&A with attendees. If you would like to view previous forums and resources, learn more about upcoming forums, or join our mailing list, please visit our website at We are open to global collaboration for evaluating REACH worldwide and to adapt the interventions to local cultures.

Aims and method

The aim of the GPS-CCC study were to better understand reactions to COVID-19 related traumatic events compared to those to other traumatic events and how these may differ, across different cultures and populations, and across different phases of the pandemic.

We invited individuals aged 16 or older, from around the world, who have experienced any difficult or frightening events, whether related to Corona virus (COVID-19) or other events such as a serious accident or fire, physical or sexual assault or abuse, earthquake or flood, war, seeing someone be killed or seriously injured, or having a loved one die through homicide or suicide, to participate in this 5 minute survey via this link

A few introductory questions lead to the Global Psychotrauma Screen (GPS) which has been developed by the Global Collaboration on Traumatic Stress (GC-TS) as a brief measure screening for a wide range of potential outcomes of trauma, as well as for risk and protective factors. It is currently available in 27 languages. (Olff., et al 2020, or GPS page). To collect the data we used the GPS web-app which allows to easily fill out the GPS including feedback to the participant.

Learning about specific responses to different types of trauma, different populations, will help us better target preventative and curative interventions.


The first phase of data collection on 7034 participants from 80 countries has finished and resulted in two published articles, see below. and one in prep (on text mining of the open field).

The data are freely available for anyone to use, analyze further, publish about etc. You can find them here: and on our FAIR data sets page.

including a 2 minute video abstract.


  • In a large global sample, COVID-19 was associated with more severe mental health symptoms compared to other stressful or traumatic events.

  • The impact of COVID-19 on mental health differed around the world with an especially large impact in Latin America.

  • COVID-19-related potentially traumatic events reflect a diverse range of trauma types.

  • Psychological responses to COVID-19-related PTEs include highly connected transdiagnostic symptoms.

  • Symptom networks related to COVID-19 PTEs are similar to those of other PTEs.

  • Depression has the most and/or strongest connections with other symptoms in the network.

Participants from all over the world (16 years and older) are still invited to help us collect global data:

Please contact Alex De Young ( if you are interested to collaborate or learn more about the research we are conducting.


Aims and method

The COVID-19 Unmasked: Young Child research project was launched in Australia on 12 May 2020 to help understand and track the impact of the COVID-19 pandemic on the mental health and wellbeing of young children (1-5 years) and their caregivers. This information will be used to promote positive wellbeing and resilience and help prevent the development and exacerbation of mental health problems in this age group over the next 12 months. The online survey is completed on 4 occasions (baseline and 3, 6, 12-months) to:

  1. Identify the challenging and positive experiences children and families have faced during this time

  2. Understand how toddlers and young children are coping, and what impacts the pandemic is having on their emotional and behavioural wellbeing

  3. Learn about the types of worries preschool children have typically experienced during this
    time and how these worries have affected their emotions, sleep and behaviour

  4. Track how many children are exposed to potentially traumatic events over the next 12-months and the impact this has on their mental health

  5. Understand the pressures on parents and caregivers of young children, and how the
    pandemic is affecting their mental health and parenting practices

  6. Identify key risk and protective factors that have influenced child and parent adjustment during this time


This information will help educators, health professionals, policymakers and service providers develop better ways of supporting young families during the course of this pandemic as well as future disruptive events (e.g. natural disasters).


Data from all participating countries will be combined to form a large cross-cultural dataset for joint publications. In line with the FAIR projects we will plan to contribute to the Child Trauma Data Archives.

10. The COVID-19 Psychological Research Consortium (C19PRC) Study

Project leader: Richard Bentall

Project Group: Kate Bennett, Sarah Butter, Jilly Gibson Miller, Todd K. Hartman, Liat Levita, Anton Martinez, Liam Mason, Orla McBride, Ryan McKay, Jamie Murphy, Mark Shevlin, Thomas VA Stocks, Philip Hyland, Frédérique Vallières, Thanos Karatzias, Carmen Valiente, Carmelo Vazquez, Justin Thomas, Abdullah Bin Dawood & Marco Bertamini

Aims and Method

The COVID-19 Psychological Research Consortium (C19PRC) Study aims to assess and monitor the psychological, social, political, and economic impact of the coronavirus (COVID-19) pandemic in the general population, using longitudinal surveys and mixed-methods studies in multiple countries (UK, Republic of Ireland, Spain, United Arab Emirates, Saudi Arabia and Italy). In the UK (which serves as the ‘parent’ arm of the study), a longitudinal, internet panel survey assessed: (1) COVID-19 related knowledge, attitudes, and behaviours; (2) the occurrence of common mental health disorders (e.g. anxiety, depression, COVID-19 related traumatic stress); as well as the role of (3) psychological factors (e.g. personality, locus of control, resilience) and (4) social and political attitudes (e.g. authoritarianism, social dominance), in influencing the public’s response to the pandemic. Quota sampling was used to recruit a nationally representative (in terms of age, sex, and household income) sample of adults at Wave 1 in March 2020 (N=2025). As of May 2021, four follow-up surveys have been conducted: Wave 2, April/May 2020; Wave 3, July/August 2020; Wave 4, Nov/Dec 2020; Wave 5, March/April 2021. Additionally, sub-studies (qualitative interviews, experience sampling study) have been conducted to examine the impact of the pandemic on specific subpopulations (i.e. older adults, pregnant women, those with health vulnerabilities), and experiment/quasi-experimental data has been collected via a range of cognitive tests to enhance the utility of the dataset to assess adherence to public health regulations.


The C19PRC Study data has strong generalisability to facilitate and stimulate interdisciplinary research on important public health questions relating to the COVID-19 pandemic.

Details of all of research outputs are available on this website.

FAIR data of this project can be found here.
