The global collaboration on traumatic stress

Adaptation and validation study of the Indonesian version of the Global Psychotrauma Screen in an undergraduate student population

BACKGROUND

The high incidence of potentially traumatic events (PTEs) in Indonesia warrants early identification of those with probable trauma-related disorders in order to tailor prevention and intervention for trauma-related symptoms.

OBJECTIVES

This study aims to adapt and validate a novel brief transdiagnostic screener, the Global Psychotrauma Screen (GPS), in Indonesian undergraduate students.

METHODS

An online survey was administered among Indonesian undergraduate students (N = 322). Exploratory factor analysis, reliability analyses, clinical validity analyses, and correlational analyses were performed to evaluate the construct validity, reliability, clinical validity, and convergent-divergent validity of the Indonesian GPS. Hierarchical multiple regression was conducted to assess the relationship between risk factors and trauma-related symptoms. The relationship between four categories of trauma-related symptom severity and social/work functioning was measured using Analysis of Covariance.

RESULTS

Exploratory factor analysis yielded a single-factor solution. The Indonesian GPS demonstrated good internal consistency, test-retest correlation, and absolute agreement, indicating good reliability. The Indonesian GPS also had an acceptable area under the curve, sensitivity, and specificity for a probable diagnosis of Post-Traumatic Stress Disorder (PTSD), Complex-PTSD (CPTSD), depression, and generalized anxiety disorder (GAD). We also established evidence for the convergent and divergent validity of GPS. The GPS risk factors (low psychological resilience, other stressful events, history of mental illness, and low social support) contributed to predicting trauma-related symptoms after controlling for gender, age, employment status, and faculty background. Additionally, in comparison to participants from the mild and low categories of GPS symptoms scores, participants from the severe and moderate category reported impaired lowered social/work functioning.

CONCLUSION

The current findings indicate that the Indonesian GPS is a valid and reliable transdiagnostic trauma screener for Indonesian undergraduate students. This first comprehensive validation of the GPS in Indonesia calls for more research in Lower-middle Income Countries (LMICs) as a way towards prevention and early intervention for trauma-related symptoms.

Childhood trauma histories in men and women assessed by the childhood attachment and relational trauma screen (CARTS) and the global psychotrauma screen (GPS): Results from the global collaboration on traumatic stress (GC-TS)

BACKGROUND

Whether there are biological sex differences in rates of childhood trauma exposure perpetrated by female versus male biological parents remains largely unknown. Moreover, the relative risk posed by various vulnerability factors for transdiagnostic mental health outcomes among females vs. males in adulthood has received insufficient attention.

OBJECTIVE

To compare biological sex differences in the long-term impact of childhood abuse and neglect on transdiagnostic mental health outcomes, especially comparing the outcomes of childhood maltreatment perpetrated by biological mothers vs. fathers.

PARTICIPANTS AND SETTING

3129 participants (2784 female [89 %]) were recruited online, the majority (82 %) of whom endorsed having a childhood trauma history and a high number of mental health problems.

METHODS

Online surveys were administered. Specifically, the Childhood Attachment and Relational Trauma Screen (CARTS) was completed as a relationally-contextualized screening measure of both positive and traumatic-neglectful experiences during childhood, comparing severity of perpetration by male vs. female biological parents. Further, the Global Psychotrauma Screen (GPS) was completed to assess the relative risk of five vulnerability factors, including childhood abuse and neglect, for long-term transdiagnostic mental health outcomes. Statistical analyses elucidate group differences between males and females primarily by way of t-tests and associated effect sizes (Cohen's d).

RESULTS

Biological sex differences were shown for childhood maltreatment perpetration by male vs. female biological parents, wherein responses to CARTS showed that females reported that their biological mothers exhibited less positivity (d = 0.21), less attachment security (d = 0.22), more negative feelings toward them (d = 0.28), were more emotionally abusive (d = 0.17), and held more negative relational beliefs about them (d = 0.24). Comparably, males reported that their biological fathers were more physically abusive (d = 0.15) and that they held more negative relational beliefs toward their fathers (d = 0.25). Risk factors including having a history of childhood trauma and neglect were associated with transdiagnostic mental health problems among both females (d = 0.57) and males (d = 0.46), with other risk factors evidencing similar results.

CONCLUSIONS

Childhood trauma and neglect is a risk factor for transdiagnostic mental health outcomes among both females and males, although the two biological sexes may exhibit different levels of risk of being maltreated by female and male biological parents. Specifically, females reported having more emotionally abusive biological mothers, while males reported having more physically abusive biological fathers.

The mental health impact of the COVID-19 pandemic and exposure to other potentially traumatic events up to old age

We investigated whether the impact of potentially traumatic events (PTEs) on trauma-related symptoms changes across the transitional adult lifespan (i.e., 16-100 years old) and if this association differs for self-reported COVID-19-related PTEs compared to other PTEs. A web-based cross-sectional study was conducted among 7,034 participants from 88 countries between late April and October 2020. Participants completed the Global Psychotrauma Screen (GPS), a self-report questionnaire assessing trauma-related symptoms. Data were analyzed using linear and logistic regression analyses and general linear models. We found that older age was associated with lower GPS total symptom scores, B = -0.02, p < .001; this association remained significant but was substantially weaker for self-reported COVID-19-related PTEs compared to other PTEs, B = 0.02, p = .009. The results suggest an association between older age and lower ratings of trauma-related symptoms on the GPS, indicating a blunted symptom presentation. This age-related trend was smaller for self-reported COVID-19-related PTEs compared to other PTEs, reflecting the relatively higher impact of the COVID-19 pandemic on older adults.

Trauma and its consequences in Iran: cross-cultural adaption and validation of the Global Psychotrauma Screen in a representative sample

BACKGROUND

Potentially traumatic events may lead to the development of a wide range of adverse psychological responses, including symptoms of anxiety, depression, and (complex) posttraumatic stress disorder (PTSD). Despite the high prevalence of potentially traumatic events in Iran, there is no population data nor evidence-based instrument to screen for cross-diagnostic psychological responses to trauma. The Global Psychotrauma Screen (GPS) is a transdiagnostic self-report instrument for the detection of trauma-related symptoms, as well as risk and protective factors related to the impact of potentially traumatic events.

OBJECTIVE

The present study seeks to 1) translate and cross-culturally adapt the GPS in the Persian (Farsi) language and 2) examine the psychometric properties of the Persian GPS.

METHOD

The translation and adaptation were performed using the Sousa and Rojjanasrirat (2011) method. A pilot study (n = 30) was carried out to test the content validity and test-retest reliability of the GPS. Next, in a representative sample (n = 800) of residents of Kermanshah City, the GPS, the General Health Questionnaire (GHQ) and the PTSD Checklist for DSM-5 (PCL-5) were administered. Construct validity of the Persian GPS was assessed using exploratory and confirmatory factor analysis. Additionally, we evaluated the convergent validity and internal consistency of the GPS.

RESULTS

Exploratory and confirmatory factor analyses indicated a three-factor model as the best solution with factors representing 1) Negative Affect, 2) Core PTSD symptoms and 3) Dissociative symptoms. The GPS total symptom score had high internal consistency and high convergent validity with related measures. A GPS total symptom cut-off score of nine was optimal for indicating a probable PTSD diagnosis based on the PCL-5. About half (52%) of the current sample met criteria for probable PTSD.

CONCLUSIONS

The current findings suggest that the GPS can be effectively adapted for use in a non-Western society and, specifically, that the Persian GPS represents a useful, reliable and valid tool for screening of trauma-related symptoms in Iran.

Don't get too close to me: depressed and non-depressed survivors of child maltreatment prefer larger comfortable interpersonal distances towards strangers

BACKGROUND

Childhood maltreatment (CM) is frequently linked to interpersonal problems such as difficulties in social relationships, loneliness, and isolation. These difficulties might partly stem from troubles regulating comfortable interpersonal distance (CIPD).

OBJECTIVE

We experimentally investigated whether CM manifests in larger CIPD and whether all subtypes of CM (i.e., physical, emotional, or sexual abuse and physical or emotional neglect) affect CIPD.

METHODS

Using the stop-distance method (i.e. a team member approached participants until the latter indicated discomfort), we assessed CIPD in 84 adults with a self-reported history of CM (24 with depressive symptoms) and 57 adult controls without a history of CM (without depressive symptoms).

RESULTS

Adults with CM showed a larger CIPD (Mdn = 86 cm) than controls (Mdn = 68 cm), and CIPD was largest for those with CM combined with current depressive symptoms (Mdn = 145 cm) (p's < .047). In the latter group, all subtypes of CM were associated with a larger CIPD compared to controls (p's < .045). In the CM group without depressive symptoms, only those with emotional abuse (p = .040) showed a larger CIPD than controls.

CONCLUSIONS

These results add to findings of differential socio-emotional long-term consequences of CM, depending upon the subtype of CM. Future research should explore whether a larger CIPD has a negative impact on social functioning in individuals exposed to CM, particularly in those with depressive symptoms.

HIGHLIGHTS

Adults with child maltreatment (CM) prefer larger physical distances.• This effect is more pronounced in those with CM and depressive symptoms.• Troubled regulation of physical distance might contribute to interpersonal problems.

Validation and cross-cultural comparisons of the German Childhood Attachment and Relational Trauma Screen (CARTS)

Background: Child maltreatment is embedded in a complex system of familial, societal and cultural influences. However, the microsystemic framework in which child maltreatment occurs has not been sufficiently accounted for in previous measures of trauma history. In order to include this relational context, a novel survey method, the Childhood Attachment and Relational Trauma Screen (CARTS), was developed, focusing specifically on the familial environment and childhood attachment relationships. Prior validation studies of the English and Italian versions of the CARTS have tended to support its use. Objective: The current study aims at evaluating the psychometric properties of the German version of the CARTS as well as conducting cross-cultural comparison analyses. It is part of an international research project of the Global Collaboration on Traumatic Stress which was initiated by the International Society for Traumatic Stress Studies (ISTSS). Method: The sample consisted of n = 140 participants from the German general population aged 18 or older. Further trauma specific measures (GPS, BSI-18, CTQ-SF, ECR-R, PBI) were included for validation. Cross-cultural comparisons were conducted with a German subsample of students in reference to Italian- and English-speaking student samples. Results: Most CARTS subscales showed acceptable internal consistency. Statistically significant relationships were observed with other measures of childhood trauma exposure and parental bonding, as well as PTSD- and other distress-related outcomes. Comparing the German-speaking sample with Italian- and English-speaking samples indicated significant differences with regard to childhood attachment and child maltreatment. Conclusion: The present findings are consistent with previous results concerning the CARTS and advance the validation of this novel survey method within German-speaking samples. Further, the CARTS appears to be sensitive to cross-sample differences in childhood attachment and child maltreatment. Further psychometric evaluations of the CARTS in other languages and within further German-speaking samples are needed.

Navigating the who, where, what, when, how and why of trauma exposure and response

Individual differences in the response to trauma are influenced by numerous contextual factors such as one's cultural background, the environment in which trauma occurs, the meanings attached to traumatic experiences, and various other social and cultural determinants both before and after traumatic exposure. This special issue of the European Journal of Psychotraumatology presents a series of papers conducted as part of the Collaborative Network for Training and Excellence in Psychotraumatology (CONTEXT); a programme of research which seeks to advance our understanding of the impact of trauma within diverse populations who are highly trauma exposed. Applying a context-specific focus, CONTEXT prioritised working closely with service users and those organisations delivering critical support in the wake of trauma exposure. The seven papers presented in this special issue are divided into those who are exposed to trauma either: (i) directly (survivors of childhood adversity in the USA; LGB youth in Northern Ireland; refugees and asylum seekers in the EU; and members of the general population exposed to conflict in Israel) or (ii) vicariously (fire fighters in the UK, humanitarian aid volunteers in Sudan, and child protection workers in Denmark). Together, findings from these studies demonstrate that social support, in its many different forms, is a universally important factor in the response to trauma. We discuss how traumatic stress can be compounded when, and can thrive within, contexts where necessary social support is absent or inadequate. We also emphasize the importance of recognizing the context specificity of trauma exposure and trauma response, as well as the need for collaboration between psychotrauma researchers and organisations who deliver support to traumatized populations to ensure rapid and effective translation of research findings into practice.

Trauma-spectrum symptoms among the Italian general population in the time of the COVID-19 outbreak

Background: Recent evidence showed adverse mental health outcomes associated with the COVID-19 pandemic, including trauma-related symptoms. The Global Psychotrauma Screen (GPS) is a brief instrument designed to assess a broad range of trauma-related symptoms with no available validation in the Italian population. Aims: This study aimed to examine the factor structure of the Italian version of the GPS in a general population sample exposed to the COVID-19 pandemic and to evaluate trauma-related symptoms in the context of COVID-19 related risk factors associated with lockdown measures. Methods: We conducted a cross-sectional web-based observational study as part of a long-term monitoring programme of mental health outcomes in the general population. Eighteen thousand one hundred forty-seven participants completed a self-report online questionnaire to collect key demographic data and evaluate trauma-related symptoms using the GPS, PHQ-9, GAD-7, ISI, and PSS. Validation analyses included both exploratory and confirmatory factor analysis and correlation analyses. The relation with putative COVID-19 related risk factors was explored by multivariate regression analysis. Results: Exploratory factor analyses supported a two-factor model. Confirmatory factor analysis showed that the best fitting model was a three-factor solution, with core Post-traumatic Stress Symptoms (PTSS) (re-experiencing, avoidance, hyperarousal), Negative Affect (symptoms of depressed mood, anxiety, irritability), and Dissociative symptoms. GPS Risk factors and specific COVID-19 related stressful events were associated with GPS total and the three factor scores. Conclusions: Our data suggest that a wide range of trauma-spectrum symptoms were reported by a large Italian sample during the COVID-19 pandemic. The GPS symptoms clustered best in three factors: Negative Affect symptoms, Core PTSS, and Dissociative symptoms. In particular, high rates of core PTSS and negative affect symptoms were associated with the COVID-19 pandemic in Italy and should be routinely assessed in clinical practice.

Mental health responses to COVID-19 around the world

Background: The mental health impact of the COVID-19 crisis may differ from previously studied stressful events in terms of psychological reactions, specific risk factors, and symptom severity across geographic regions worldwide. Objective: To assess the impact of COVID-19 on a wide range of mental health symptoms, to identify relevant risk factors, to identify the effect of COVID-19 country impact on mental health, and to evaluate regional differences in psychological responses to COVID-19 compared to other stressful events. Method: 7034 respondents (74% female) participated in the worldwide Global Psychotrauma Screen - Cross-Cultural responses to COVID-19 study (GPS-CCC), reporting on mental health symptoms related to COVID-19 (n = 1838) or other stressful events (n = 5196) from April to November 2020. Results: Events related to COVID-19 were associated with more mental health symptoms compared to other stressful events, especially symptoms of PTSD, anxiety, depression, insomnia, and dissociation. Lack of social support, psychiatric history, childhood trauma, additional stressful events in the past month, and low resilience predicted more mental health problems for COVID-19 and other stressful events. Higher COVID-19 country impact was associated with increased mental health impact of both COVID-19 and other stressful events. Analysis of differences across geographic regions revealed that in Latin America more mental health symptoms were reported for COVID-19 related events versus other stressful events, while the opposite pattern was seen in North America. Conclusions: The mental health impact of COVID-19-related stressors covers a wide range of symptoms and is more severe than that of other stressful events. This difference was especially apparent in Latin America. The findings underscore the need for global screening for a wide range of mental health problems as part of a public health approach, allowing for targeted prevention and intervention programs.

Screening for psychotrauma related symptoms: Japanese translation and pilot testing of the Global Psychotrauma Screen

Background: The impact of traumatic experiences or adverse life experiences has been shown to potentially affect a wide range of mental health outcomes. However, there was no brief instrument to screen for a range of psychological problems in different domains after a potentially traumatic event, and for risk factors and protective factors. Objective: The aim of this study is to examine the internal consistency and concurrent validity of the Japanese version of the Global Psychotrauma Screen (GPS) in a traumatized sample in Japan. Method: A total sample (n = 58) with varying levels of potential posttrauma symptoms due to domestic violence or other events were recruited into this study. Self-rating measures of posttraumatic stress disorder (PTSD), depression, anxiety, and alcohol problems were conducted to investigate the concurrent validity. Results: The results show that a range of posttrauma symptoms assessed by the GPS were highly endorsed by this traumatized sample in all domains except for self-harm, derealization, and depersonalization. The GPS sum score was highly correlated (r > 0.79) with other measures of PTSD, depression, and anxiety symptoms. Also, the subdomain scores showed acceptable correlations with corresponding domain measures. Participants who had been sexually assaulted or had unwanted sexual experiences, and participants who had been physically assaulted during childhood, had higher scores on the total GPS and on subdomains of PTSD, as well as symptoms associated with Complex PTSD. Conclusions: This study provides an initial indication that the GPS may be a useful screening tool for trauma survivors and elucidates that the consequences of trauma are not limited to PTSD.

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

This editorial argues that it is time for the traumatic stress field to join the growing international movement towards Findable, Accessible, Interoperable, and Re-usable (FAIR) research data, and that we are well-positioned to do so. The field has a huge, largely untapped resource in the enormous number of rich potentially re-usable datasets that are not currently shared or preserved. We have several promising shared data resources created via international collaborative efforts by traumatic stress researchers, but we do not yet have common standards for data description, sharing, or preservation. And, despite the promise of novel findings from data sharing and re-use, there are a number of barriers to researchers' adoption of FAIR data practices. We present a vision for the future of FAIR traumatic stress data, and a call to action for the traumatic stress research community and individual researchers and research teams to help achieve this vision.

Screening for consequences of trauma - an update on the global collaboration on traumatic stress

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. English language data and ongoing studies in several languages provide a first indication that the GPS is a feasible, reliable and valid tool, a tool that may be very useful in the current pandemic of the coronavirus disease 2019 (COVID-19). Further multi-language and cross-cultural validation is needed. Since the start of the GC-TS, new themes have been introduced to focus on in the coming years: a) Forcibly displaced persons, b) Global prevalence of stress and trauma related disorders, c) Socio-emotional development across cultures, and d) Collaborating to make traumatic stress research data "FAIR". The most recent theme added is that of Global crises, currently focusing on COVID-19-related projects.

A decennial review of psychotraumatology: what did we learn and where are we going?

On 6 December 2019 we start the 10th year of the European Journal of Psychotraumatogy (EJPT), a full Open Access journal on psychotrauma. This editorial is part of a special issue/collection celebrating the 10 years anniversary of the journal where we will acknowledge some of our most impactful articles of the past decade (also discussed below and marked with * in the reference list). In this editorial the editors present a decennial review of the field addressing a range of topics that are core to both the journal and to psychotraumatology as a discipline. These include neurobiological developments (genomics, neuroimaging and neuroendocrine research), forms of trauma exposure and impact across the lifespan, mass trauma and early interventions, work-related trauma, trauma in refugee populations, and the potential consequences of trauma such as PTSD or Complex PTSD, but also resilience. We address innovations in psychological, medication (enhanced) and technology-assisted treatments, mediators and moderators like social support and finally how new research methods help us to gain insights in symptom structures or to better predict symptom development or treatment success. We aimed to answer three questions 1. Where did we stand in 2010? 2. What did we learn in the past 10 years? 3. What are our knowledge gaps? We conclude with a number of recommendations concerning top priorities for the future direction of the field of psychotraumatology and correspondingly the journal.

Trauma-related disorders in a low- to middle-income country: A four-year follow-up of outpatient trauma in Brazil

Acute stress disorder (ASD) and post-traumatic stress disorder (PTSD) are developed from exposure to traumatic events including war, interpersonal violence and natural disasters. We investigated prevalence and trauma-related information in patients from an outpatient psychiatric unit in Brazil among 2014-2017. A prevalence of ASD/PTSD of 40.8% was found in 179 patients. Female, Caucasian, married, mostly educated during 10-12 years long and employed patients composed a main profile. The presence of any previous trauma in adulthood and childhood were related to ASD/PTSD with longer follow-up time. This study provides evidence of stress-related disorders in a heterogeneous environment.

Parenting and Child Development: A Relational Health Perspective

A child's development is embedded within a complex system of relationships. Among the many relationships that influence children's growth and development, perhaps the most influential is the one that exists between parent and child. Recognition of the critical importance of early parent-child relationship quality for children's socioemotional, cognitive, neurobiological, and health outcomes has contributed to a shift in efforts to identify relational determinants of child outcomes. Recent efforts to extend models of relational health to the field of child development highlight the role that parent, child, and contextual factors play in supporting the development and maintenance of healthy parent-child relationships. This review presents a parent-child relational health perspective on development, with an emphasis on socioemotional outcomes in early childhood, along with brief attention to obesity and eating behavior as a relationally informed health outcome. Also emphasized here is the parent-health care provider relationship as a context for supporting healthy outcomes within families as well as screening and intervention efforts to support optimal relational health within families, with the goal of improving mental and physical health within our communities.

Facts on psychotraumatology

Daily news is dominated by reports of traumatic events across the world. Is trauma indeed rather the norm than the exception? What are the facts? How can we better understand, prevent and treat the consequences of trauma? This past year the European Journal of Psychotraumatology (EJPT) has again tried to address these questions. With the gold Open Access model articles in the journal are being made immediately available without any barriers to access. In Europe, promising developments with regard to Open Science emerged in 2018, for instance, cOAlition S with their ambitious Plan S boosting the transition to full Open Access. In this editorial these and other developments in the journal, such as Registered Reports as a way to reduce Questionable Research Practices (QRPs), journal metrics, and the ESTSS EJPT award finalists for best paper of 2018 are being presented.

Trauma and trauma care in Europe

The European countries have a long history of exposure to large-scale trauma. In the early 1990s the increasing awareness of the consequences of trauma within the mental health community led to the foundation of local societies for psychotraumatology across Europe and the European Society of Traumatic Stress Studies (ESTSS), which celebrated its 25th anniversary in 2018. The focus of this article is to describe the current state of care for survivors of trauma in the 15 European countries where ESTSS member societies have been established. Brief descriptions on the historical burden of trauma in each country are followed by an overview of the care system for trauma survivors in the countries, the state-of-the-art of interventions, current challenges in caring for survivors and the topics that need to be most urgently addressed in the future. The reports from the different countries demonstrate how important steps towards a better provision of care for survivors of trauma have been made in Europe. Given the cultural and economic diversity of the continent, there are also differences between the European countries, for instance with regard to the use of evidence-based treatments. Strategies to overcome these differences, like the new ESTSS training curricula for care-providers across Europe, are briefly discussed.

Children and natural disasters

The number of children affected by natural disasters each year is alarmingly high and can be expected to rise as climate change continues. The mental consequences have been documented not only in the rates of post-traumatic stress symptoms and post-traumatic stress disorder, but also for depression and other mental health problems. To contribute towards the knowledge in this area, this special issue of the European Journal of Psychotraumatology focuses on how children can be prepared for natural disasters and the mental health aspects of such events. It includes articles on communicating risks to children, involving children in disaster risk reduction, and the mental health consequences for children from an earthquake, a volcanic eruption, a flood and a hurricane. In this special issue specifically focusing on children and natural disasters, we hope to enhance our understanding of some of the complex pathways and pave the way for improving our interventions.

Child maltreatment across the lifespan

The present editorial introduces selected research for a special issue covering the 15th Annual Meeting of the European Society for Traumatic Stress Studies (ESTSS) 2017, 'Child Maltreatment across the Lifespan'. Unfortunately, childhood maltreatment is highly prevalent around the world. Exposure to child maltreatment is associated with a considerable risk of developing a wide range of psychopathologies. Thus, preventing child maltreatment and offering early treatment to victims is an important and promising area in reducing the risk of psychopathology. The 10 articles included in the special issue focus on different important areas related to the topic of child maltreatment. These include a biological and systemic understanding of maltreatment, a globalization perspective, and contributions on diagnosis and treatment, with implications for clinical practice. Furthermore, the special issue includes an update on ICD-11 and implications associated with the implementation of ICD-11. Future research recommendations are provided to underline the enduring need to promote and undertake research into all aspects of child maltreatment.
