Embracing data preservation, sharing, and re-use in traumatic stress research

Posttraumatic stress and depression symptom classes in parents of trauma-exposed children: a transdiagnostic perspective using pooled individual participant data

Background: In the aftermath of child trauma, post-traumatic stress (PTS) and depression symptoms often co-occur among trauma exposed children and their parents. Studies have used latent class analysis (LCA) to examine PTS and depression symptoms and identify homogeneous subgroups among trauma exposed children. However, little is known about subgroups or classes of PTS and depression reactions of parents of traumatised children.Objectives: (1) Determine PTS and depression symptom classes at 2-9 months post-trauma, and (2) to examine sociodemographic covariates among parents of trauma exposed children.Methods: Using harmonised individual participant data (n = 702) from eight studies (Australia, UK, US) included in the Prospective studies of Acute Child Trauma and Recovery Data Archive (PACT/R), we modelled these phenomena at the symptom level using LCA.Results: Our LCA yielded three solutions: 'high internalizing symptom' class (11%); 'low PTS-high depression' class (17%); and 'low internalizing symptom' class (72%). Parents of children in the 'low PTS-high depression' class were more likely to have children of older age and be part of an ethnic minority, compared to the 'low internalizing symptoms' class. Mothers were more likely to be in the 'high internalizing symptom' class compared to the 'low internalizing symptoms' class.Conclusions: These findings reveal a qualitative structure and relationship between depression and PTS symptoms that highlights the importance of assessing and targeting a broad range of internalising symptoms in post-trauma psychological treatment.

Towards a more comprehensive understanding of PTSD and parenting

BACKGROUND

The impact of post-traumatic stress disorder (PTSD) on parenting and the parent-child relationship has been well-documented in the scientific literature. However, some conceptual and methodological challenges within this research field remain.

PROCEDURE

We reflect on a number of challenges that we identified while examining the literature in preparation of an individual participant data meta-analysis on the relationships between PTSD and parenting.

FINDINGS

We address 1) the presence of 'trauma-islands'; 2) the need for transdiagnostic theoretical frameworks for mechanisms between PTSD and parenting; 3) the lack of developmental perspectives; 4) the overuse of self-reported retrospective measures; 5) the need to study more diverse samples and cultural contexts; and 6) the lack of research on resilience and post-traumatic growth in parenting. Based on these reflections, we offer suggestions on strategies for responding to these challenges through: 1) welcoming open science; 2) working towards shared theoretical frameworks; 3) doing more longitudinal research 4) expanding the methodological palette; 5) centering lived experience; and 6) taking systemic inequality into account.

CONCLUSION

With this commentary, we aim to open a discussion on next steps towards a more comprehensive understanding of the association between PTSD and parenting, and inspire collaborative research.

Opportunities for improving data sharing and FAIR data practices to advance global mental health

It is crucial to optimize global mental health research to address the high burden of mental health challenges and mental illness for individuals and societies. Data sharing and reuse have demonstrated value for advancing science and accelerating knowledge development. The FAIR (Findable, Accessible, Interoperable, and Reusable) Guiding Principles for scientific data provide a framework to improve the transparency, efficiency, and impact of research. In this review, we describe ethical and equity considerations in data sharing and reuse, delineate the FAIR principles as they apply to mental health research, and consider the current state of FAIR data practices in global mental health research, identifying challenges and opportunities. We describe noteworthy examples of collaborative efforts, often across disciplinary and national boundaries, to improve Findability and Accessibility of global mental health data, as well as efforts to create integrated data resources and tools that improve Interoperability and Reusability. Based on this review, we suggest a vision for the future of FAIR global mental health research and suggest practical steps for researchers with regard to study planning, data preservation and indexing, machine-actionable metadata, data reuse to advance science and improve equity, metrics and recognition.

Data sharing and re-use in the traumatic stress field: An international survey of trauma researchers

BACKGROUND

The FAIR data principles aim to make scientific data more Findable, Accessible, Interoperable, and Reusable. In the field of traumatic stress research, FAIR data practices can help accelerate scientific advances to improve clinical practice and can reduce participant burden. Previous studies have identified factors that influence data sharing and re-use among scientists, such as normative pressure, perceived career benefit, scholarly altruism, and availability of data repositories. No prior study has examined researcher views and practices regarding data sharing and re-use in the traumatic stress field.

OBJECTIVE

To investigate the perspectives and practices of traumatic stress researchers around the world concerning data sharing, re-use, and the implementation of FAIR data principles in order to inform development of a FAIR Data Toolkit for traumatic stress researchers.

METHOD

A total of 222 researchers from 28 countries participated in an online survey available in seven languages, assessing their views on data sharing and re-use, current practices, and potential facilitators and barriers to adopting FAIR data principles.

RESULTS

The majority of participants held a positive outlook towards data sharing and re-use, endorsing strong scholarly altruism, ethical considerations supporting data sharing, and perceiving data re-use as advantageous for improving research quality and advancing the field. Results were largely consistent with prior surveys of scientists across a wide range of disciplines. A significant proportion of respondents reported instances of data sharing and re-use, but gold standard practices such as formally depositing data in established repositories were reported as infrequent. The study identifies potential barriers such as time constraints, funding, and familiarity with FAIR principles.

CONCLUSIONS

These results carry crucial implications for promoting change and devising a FAIR Data Toolkit tailored for traumatic stress researchers, emphasizing aspects such as study planning, data preservation, metadata standardization, endorsing data re-use, and establishing metrics to assess scientific and societal impact.

Sexual assault as a public health problem and other developments in psychotraumatology

A recent scandal in the Netherlands painfully underscored that sexual harassment and abuse are unfortunately still happening around the world, even after decades of advocacy on this issue and five years of #MeToo. To make progress in prevention and treatment we argue that we should address sexual violence from a public health perspective. Fruthermore, looking back on the past year, the COVID-19 pandemic was the dominant and potentially traumatic stressor affecting large populations around the world. Another big topic was that of the impact of climate change, we are only beginning to realize its impact on stress across the globe. The European Journal of Psychotraumatology (EJPT), with its increasing global readership and scientific and social impact, is focusing on the traumatic stress aspects of these and many other events. Relatedly, neurobiological aspects are an important and growing focus of the journal in that they help us better understand the mechanisms behind the development of trauma-related disorders and their treatment. In this editorial, we present recent trends, new Open Science developments, journal metrics, the plans and themes for next year and the ESTSS EJPT award winners for best paper of 2021.

Highlights

Next years' research focus should be on sexual violence from a public health lens, climate change, and neurobiologal aspects of trauma-related disorders. The European Journal of Psychotraumatology (EJPT) calls or papers on these issues.

COVID-19 Unmasked Global Collaboration Protocol: longitudinal cohort study examining mental health of young children and caregivers during the pandemic

BACKGROUND

Early empirical data shows that school-aged children, adolescents and adults are experiencing elevated levels of anxiety and depression during the COVID-19 pandemic. Currently, there is very little research on mental health outcomes for young children.

OBJECTIVES

To describe the formation of a global collaboration entitled, 'COVID-19 Unmasked'. The collaborating researchers aim to (1) describe and compare the COVID-19 related experiences within and across countries; (2) examine mental health outcomes for young children (1 to 5 years) and caregivers over a 12-month period during the COVID-19 pandemic; (3) explore the trajectories/time course of psychological outcomes of the children and parents over this period and (4) identify the risk and protective factors for different mental health trajectories. Data will be combined from all participating countries into one large open access cross-cultural dataset to facilitate further international collaborations and joint publications.

METHODS

COVID-19 Unmasked is an online prospective longitudinal cohort study. An international steering committee was formed with the aim of starting a global collaboration. Currently, partnerships have been formed with 9 countries (Australia, Cyprus, Greece, the Netherlands, Poland, Spain, Turkey, the UK, and the United States of America). Research partners have started to start data collection with caregivers of young children aged 1-5 years old at baseline, 3-months, 6-months, and 12-months. Caregivers are invited to complete an online survey about COVID-19 related exposure and experiences, child's wellbeing, their own mental health, and parenting.

DATA ANALYSIS

Primary study outcomes will be child mental health as assessed by scales from the Patient-Reported Outcomes Measurement Information System - Early Childhood (PROMIS-EC) and caregiver mental health as assessed by the Depression Anxiety Stress Scale (DASS-21). The trajectories/time course of mental health difficulties and the impact of risk and protective factors will be analysed using hierarchical linear models, accounting for nested effects (e.g. country) and repeated measures.

To share or not to share - 10 years of European Journal of Psychotraumatology

The European Journal of Psychotraumatology, owned by the European Society for Traumatic Stress Studies (ESTSS), launched as one of the first full Open Access 'specialist' journals in its field. Has this Open Access model worked in how the Journal has performed? With the European Journal of Psychotraumatology celebrating its ten-year anniversary we look back at the past decade of sharing our research with the world and with how the journal sits with the broader movement beyond Open Access to Open Research and we present new policies we have adopted to move the field of psychotraumatology to the next level of Open Research. While we as researchers now make our publications more often freely available to all, how often do we share our protocols, our statistical analysis plans, or our data? We all gain from more transparency and reproducibility, and big steps are being made in this direction. The journal's decennial performance as well as the exciting new Open Research developments are presented in this editorial. The journal is no longer in its infancy and eager to step into the next decade of Open Research.
