Treatment Gap in Mental Health Care for Victims of Road Traffic Accidents.

Road traffic accidents (RTAs) are among the most frequent negative life-events. About one in five RTA survivors is susceptible to posttraumatic stress disorder (PTSD). Knowledge about needs for, and usage of, mental health services (MHSs) may improve options for care for RTA victims. The current study aimed to assess rates of victims using different MHSs, including psychotherapy, pharmacotherapy and support groups, and to explore correlates of needs for and use of these MHSs. Further, we aimed to estimate the treatment gap in post-RTA care, defined as including people with probable PTSD who did not use MHSs and people wanting but not getting help from MHSs. Dutch victims of nonlethal RTAs (N = 259) completed self-report measures on needs for and use of MHSs and PTSD. Results showed that 26% of participants had utilized care from psychotherapy, pharmacotherapy or support groups. Among people with probable PTSD, this was 56%. Increased posttraumatic stress was the strongest correlate of MHS use. Forty-eight participants (17.8%) had an unmet care need and represented the treatment gap. Commonly reported reasons and barriers preventing MHS use were perceptions that problems were limited or would disappear without care and financial worries. Regarding possible future care, participants reported a preference for face-to-face (over online) help from a psychologist (over other professionals). The treatment gap for Dutch RTA victims may be limited. However, a significant number of RTA victims need care but do not obtain this care. Care options may be improved by reducing practical barriers to MHSs and increasing mental health literacy and acceptability of different forms of care (besides face-to-face care).

Psychometric evaluation of the Swedish Traumatic Grief Inventory Self-Report Plus (TGI-SR+) in bereaved parents.

The International Classification of Diseases Eleventh Edition (ICD-11), and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR), now include prolonged grief disorder (PGD). Since criteria for PGD in both classification systems differ from prior proposed grief disorders and each other, the validation of a single instrument to screen for prolonged grief (PG) symptoms of both new diagnoses is critical for bereavement research and care. Therefore, we evaluated the psychometric properties of the Swedish version of the Traumatic Grief Inventory Self-Report Plus (TGI-SR+). Two-hundred and forty-eight bereaved parents completed questions about sociodemographic and loss-related variables, the TGI-SR+, and symptom measures of post-traumatic stress (PTS), depression and an older measure of PG symptoms, the Prolonged Grief Disorder-13 (PG-13). Confirmatory factor analyses showed that a one-factor model best fit DSM-5-TR and ICD-11 PG symptoms and the analyses of the internal consistency and inter-item correlations showed that these symptoms could be reliably assessed. In support of convergent validity, DSM-5-TR and ICD-11 PG symptoms correlated with symptoms of PTS, depression and PG assessed with the PG-13. In support of known-groups validity, DSM-5-TR and ICD-11 PG symptoms were higher among lower educated (vs. higher educated) participants and related negatively to time since loss. ROC analyses showed optimal cut-off score of ≥71 and ≥72 to determine probable caseness for DSM-5-TR and ICD-11 PGD, respectively. Results support the reliability and validity of the Swedish TGI-SR+ as a screening instrument for PG in research and bereavement care.

The ICD-11 and DSM-5-TR prolonged grief criteria: Validation of the Traumatic Grief Inventory-Self Report Plus using exploratory factor analysis and item response theory.

More recently, the prolonged grief disorder (PGD) has been recognized as a mental health disorder following bereavement, which is distinct from depression and PTSD. However, the number and proposed symptom items vary across the ICD-11 and the DSM-5-TR criteria for PG. The Traumatic Grief Inventory-Self Report Plus (TGI-SR+), which is an updated version of the TGI-SR, is currently the only robust instrument that assesses PG according to the ICD-11 and DSM-5-TR criteria. For research and clinical use among French-speaking countries, the forward-backward procedure was applied to translate the TGI-SR+ into French language. Exploratory factor analysis and parallel analysis converged towards a two-dimensional structure for the TGI-SR+, representing adaptation difficulties and traumatic separation distress. However, items mapping onto ICD-11 and DSM-5-TR criteria for PG represented a one-dimensional structure. Findings based on item response theory method provided strong evidence for discriminative characteristics of the items. The internal reliability was excellent for the TGI-SR+ (McDonald's ω = 0.97) and ICD-11 and DSM-5-TR criteria for PGD (McDonald's ω = 0.95). We also demonstrated a very high temporal stability for the TGI-SR+ total score (ICC = .91, p < 0.0001) and ICD-11 PGD and DSM-5-TR PGD (ICC = 0.90, and ICC = 0.88, ps < 0.0001, respectively). The concurrent validity of the instrument was also demonstrated, such that the TGI-SR+ total score and all combinations were positively and significantly associated with the levels of depression, anxiety and post-traumatic stress symptoms. However, the effect sizes were moderate. We conclude that for research and clinical use among French bereaved populations, the TGI-SR+ is a sound tool with very good psychometric properties.

The importance of harmonising diagnostic criteria sets for pathological grief.

Five diagnostic criteria sets for pathological grief are currently used in research. Studies evaluating their performance indicate that it is not justified to generalise findings regarding prevalence rates and predictive validity across studies using different diagnostic criteria of pathological grief. We provide recommendations to move the bereavement field forward.

Treatment gap in bereavement care: (Online) bereavement support needs and use after traumatic loss.

People bereaved through road traffic accidents (RTAs) are at risk for severe and disabling grief (i.e., pathological grief). Knowledge about needs and use of bereavement care, including psychotherapy, pharmacotherapy, and support groups, is limited. This study charted (correlates of) the needs and use of bereavement care in RTA bereaved people. Furthermore, although online grief treatment seems effective, it is unknown whether it is perceived as acceptable. Accordingly, we examined the acceptability of online treatment. Dutch RTA bereaved adults (N = 273) completed self-report measures about needs and use of bereavement care, acceptability of online grief treatment, and pathological grief. Regression analyses were used to identify correlates of care needs and use and acceptability of online treatment. The majority (63%) had received help from psychotherapy, pharmacotherapy, and/or support groups. One in five participants had not used bereavement care services, despite reporting elevated pathological grief levels and/or expressing a need for care, pointing to a treatment gap. Use of psychological support before the loss was the strongest predictor of bereavement care needs and use following the loss. A minority (35%) reported being inclined to use online grief treatment if in need of support. More openness towards online services was related to greater acceptability of online treatment. In conclusion, 20% of RTA bereaved people with pathological grief or care needs had not received care. This treatment gap may be reduced by improving accessibility of online treatments. However, as only 35% was open to using online treatments, increasing the acceptability of (online) treatments appears important.

Trajectories of grief, depression, and posttraumatic stress in disaster-bereaved people.

BACKGROUND: Previous latent trajectory studies in adult bereaved people have identified individual differences in reactions postloss. However, prior findings may not reflect the complete picture of distress postloss, because they were focused on depression symptoms following nonviolent death. We examined trajectories of symptom-levels of persistent complex bereavement disorder (PCBD), depression, and posttraumatic stress disorder (PTSD) in a disaster-bereaved sample. We also investigated associations among these trajectories and background and loss-related factors, psychological support, and previous mental health complaints. METHODS: Latent class growth modeling was used to identify distinct trajectories of PCBD, depression, and PTSD symptoms in people who lost loved ones in a plane disaster in 2014. Participants (N = 172) completed questionnaires for PCBD, depression, and PTSD at 11, 22, 31, and 42 months postdisaster. Associations among class membership and background and loss-related variables, psychological support, and previous mental health complaints were examined using logistic regression analyses. RESULTS: Two PCBD classes emerged: mild (81.8%) and chronic (18.2%) PCBD. For both depression and PTSD, three classes emerged: mild (85.6% and 85.2%), recovered (8.2% and 4.4%), and chronic trajectory (6.2% and 10.3%). People assigned to the chronic PCBD, depression, or PTSD class were less highly educated than people assigned to the mild/recovered classes. CONCLUSIONS: This is the first latent trajectory study that offers insights in individual differences in longitudinal symptom profiles of PCBD, depression, and PTSD in bereaved people. We found support for differential trajectories and predictors across the outcomes.

Symptoms of prolonged grief, posttraumatic stress, and depression in recently bereaved people: symptom profiles, predictive value, and cognitive behavioural correlates.

PURPOSE: Prior latent class analyses (LCA) have focused on people who were bereaved more than 6 months earlier. Research has yet to examine patterns and correlates of emotional responses in the first few months of bereavement. We examined whether subgroups could be identified among very recently (≤ 6 months) bereaved adults, based on their endorsement of symptoms of prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD), and depression. Associations of class membership with overall disturbed grief, PTSD, and depression-assessed concurrently and at 6 months follow-up-were examined. Furthermore, we examined differences between classes regarding socio-demographics, loss-related, and cognitive behavioural variables. METHODS: PGD, PTSD, and depression self-report data from 322 Dutch individuals bereaved ≤ 6 months earlier were subjected to LCA; N = 159 completed the follow-up assessment. Correlates of class membership were examined. RESULTS: Three classes were identified: a low symptom class (N = 114; 35.4%), a predominantly PGD class (N = 96; 29.8%), and a high symptom class (N = 112; 34.8%). PGD, PTSD, and depression scores (assessed concurrently and at 6 months follow-up) differed significantly between classes, such that low symptom class < predominantly PGD class < high symptom class. Being a woman, younger, more recently bereaved, experiencing deaths of a partner/child and unnatural losses, plus maladaptive cognitions and avoidance behaviours were associated with membership of the pervasive symptom classes. CONCLUSION: In the first 6 months of bereavement, meaningful subgroups of bereaved people can be distinguished, which highlights the relevance of early detection of people with elevated bereavement-related distress and offering them preventive interventions that foster adaptation to loss.

Wish you were here: The Dutch, German, and English Yearning in Situations of Loss Short Form.

OBJECTIVE(S): Yearning, a hallmark of grief disorders, relates to rumination and potentially to cognitive avoidance. We developed an 8-item short form of the only existing validated yearning measure, the Yearning in Situations of Loss Scale (YSL), to improve its validity and administration ease. METHOD: Cross-sectional surveys were conducted among bereaved Dutch (N = 313) and German (N = 235) community samples and an American treatment-seeking sample (N = 95). All samples completed the YSL, and community samples additionally measures of rumination, loss-related avoidance, complicated grief (CG), and depression. RESULTS: A one-factor model provided a good fit to the YSL Short Form (YSL-SF) in the community samples. A two-factor structure (cognitive and emotional yearning)best fitted the YSL-SF in the treatment-seeking sample. YSL-SF scores correlated positively with rumination, loss-related avoidance, and with CG symptoms whilst controlling for rumination and loss-related avoidance. CONCLUSION: The YSL-SF appears an easy-to-administer and valid measure of yearning after bereavement.

Associations of depressive rumination and positive affect regulation with emotional distress after the death of a loved one.

The death of a loved one may precipitate symptoms of prolonged grief disorder (PGD), post-traumatic stress disorder (PTSD) and depression. Brooding about the causes and consequences of one's negative affect (NA), also termed depressive rumination, has been linked to distress after loss. The role of dysregulation of positive affect (PA) has received less attention. We examined (1) the factor structure of depressive rumination and PA dysregulation and (2) to what extent these factors were related to PGD, PTSD and depression symptom levels. Self-report data were included from 235 Dutch bereaved people who completed measures tapping symptoms of PGD, PTSD and depression. Depressive rumination and PA regulation strategies were assessed with the Ruminative Response Scale (RRS) Brooding Scale and the Response to Positive Affect (RPA) Questionnaire (including three subscales: emotion-focused and self-focused rumination and dampening), respectively. Confirmatory factor analyses and structural equation modelling were used for data analyses. The four-factor model (i.e., depressive rumination and the three RPA subscales) showed the best fit. An increase in depressive rumination was related to higher distress levels (across all outcomes in univariate and multivariate analyses). An increase in emotion-focused rumination about PA was associated with less depression. More dampening of PA was related to higher PTSD levels. Findings suggest that, alongside the regulation of NA, the regulation of PA plays a role in how people respond to the death of a loved one. This points to the need for more research on NA and PA regulation in grief.

Patterns, Predictors, and Prognostic Validity of Persistent Complex Bereavement Disorder Symptoms in Recently Bereaved Adults: A Latent Class Analysis.

Persistent complex bereavement (PCBD) was entered to DSM-5. No studies have yet examined the nature, prevalence, prognostic validity, and underlying mechanisms of PCBD symptom patterns in recently bereaved people. Knowledge on these issues could improve the early identification and treatment of disturbed grief. Latent class analysis was used to identify subgroups characterized by different PCBD symptom patterns among recently (≤6 months) bereaved adults (n = 476). In a subgroup (n = 251), we assessed associations of class membership with PCBD severity and functional impairment assessed 3 years later. Associations between class membership and sociodemographic and cognitive-behavioral variables were also examined. We identified a resilient (50.0%), separation distress (36.1%), and high PCBD symptoms (13.9%) class. Class membership had prognostic value as evidenced by associations with PCBD severity and functional impairment assessed 3 years later. Deaths of partners/children, unexpectedness of the loss, and maladaptive cognitions and avoidance behaviors were also associated with membership of the pervasive symptom classes.

Further validation of the Traumatic Grief Inventory-Self Report (TGI-SR): A measure of persistent complex bereavement disorder and prolonged grief disorder.

The Traumatic Grief Inventory Self-Report version (TGI-SR) is an 18-item self-report measure. It was designed to assess symptoms of Persistent Complex Bereavement Disorder (PCBD) included in Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 and Prolonged Grief Disorder (PGD) proposed by an international group of experts in grief. The research in this article used data from a bereaved patient sample and people who lost loved ones in the Ukrainian airplane crash in July 2014. Findings indicated that the TGI-SR is a reliable and valid tool to assess disturbed grief in research and to identify people needing a more comprehensive assessment of their grief in clinical settings.

Exploration of the Associations Between Responses to Affective States and Psychopathology in Two Samples of People Confronted With the Loss of a Loved One.

Adaptive regulation of positive and negative affect after the loss of a loved one may foster recovery. In two studies, using similar methods but different samples, we explored the association between positive (i.e., dampening and enhancing) and negative (i.e., rumination) affect regulation strategies and symptoms levels of postloss psychopathology. Study 1 used data from 187 people confronted with the death of a loved one. In study 2, the sample consisted of 134 relatives of long-term missing persons. Participants completed self-reports tapping prolonged grief, depression, posttraumatic stress symptoms, and affect regulation strategies. Hierarchical regression analyses showed that both negative and positive affect regulation strategies explained significant amounts of variance symptom levels in both samples. In line with previous work, our results suggest that negative and positive affect regulation strategies relate to postloss psychopathology. Future research should explore how both affect regulation strategies may adequately be addressed in treatment.

I've changed, but I'm not less happy: Interview study among nonclinical relatives of long-term missing persons.

Twenty-three nonclinical relatives of long-term missing persons were interviewed. Patterns of functioning over time were studied retrospectively by instructing participants to draw a graph that best described their pattern. Patterns most frequently drawn were a recovery and resilient/stable pattern. Participants were also asked to select 5 out of 15 cards referring to coping strategies, which they considered most helpful in dealing with the disappearance. Acceptance, emotional social support, mental disengagement, and venting emotions were most frequently chosen. This study provided some indication of coping strategies that could be strengthened in treatment for those in need of support.

Latent class analysis of indicators of intolerance of uncertainty.

Intolerance of Uncertainty (IU) is a transdiagnostic vulnerability factor involved in depression and anxiety symptoms and disorders. IU encompasses Prospective IU ("Unforeseen events upset me greatly") and Inhibitory IU ("The smallest doubt can stop me from acting"). Research has yet to explore whether subgroups or classes of people exist characterized by different profiles of IU. This study used latent class analysis to identify such subgroups and examined if different classes of IU were distinct in terms of several cognitive vulnerabilities and psychological symptoms. Data were obtained from 519 students completing a 12-item measure of IU. Four subgroups were identified, characterized by low IU, predominantly Prospective IU, predominantly Inhibitory IU, and high IU, respectively. People in the high IU class reported cognitive vulnerabilities and depression and anxiety more than people in the low IU class. Inhibitory IU was more strongly associated with poor outcomes than was Prospective IU.

Media experiences and associations with mental health among the bereaved of the MH17-disaster: A latent profile analysis.

Research has shown that the amount of media exposure is associated with post-event mental health problems. Whether bereaved individuals have negative experiences with media reports and whether they are associated with post-event mental health is unclear. This study evaluated these experiences and associations following the MH17-disaster. How media reports were experienced (nine topics, modified MAS), depression symptoms (QIDS-SR), functional problems (WSAS) and event-related coping-self-efficacy (CSE) were assessed about one year post-disaster (May-August 2015) among Dutch bereaved (N = 152). A substantial minority reported negative experiences such as reports made me angry (30%) and made me sad (48%). Latent profile analysis with symptoms, problems and coping self-efficacy as indicators, identified four classes of post-disaster mental health: a Well-functioning(class 1) , 35.1%; a Mild-problems(class 2) , 30.4%; a Sub-clinical(class 3) , 27.0%; and a Clinical(class 4) , 7.4%. Differences in symptoms, problems and coping self-efficacy levels between classes were large according to Cohen's ds. Multivariate logistic regression (MLR) showed that the Clinical(class 4) compared to the Well-functioning(class 1) , more often that felt that reports strongly "embarrassed me," "made me feel sad," "filled me with fear" and "served as a magnifying glass." Future research should assess opportunities and effects of limiting media consumption.

The COPD-SIB: a newly developed disease-specific item bank to measure health-related quality of life in patients with chronic obstructive pulmonary disease.

BACKGROUND: Health-related quality of life (HRQoL) is widely used as an outcome measure in the evaluation of treatment interventions in patients with chronic obstructive pulmonary disease (COPD). In order to address challenges associated with existing fixed-length measures (e.g., too long to be used routinely, too short to ensure both content validity and reliability), a COPD-specific item bank (COPD-SIB) was developed. METHODS: Items were selected based on literature review and interviews with Dutch COPD patients, with a strong focus on both content validity and item comprehension. The psychometric quality of the item bank was evaluated using Mokken Scale Analysis and parametric Item Response Theory, using data of 666 COPD patients. RESULTS: The final item bank contains 46 items that form a strong scale, tapping into eight important themes that were identified based on literature review and patient interviews: Coping with disease/symptoms, adaptability; Autonomy; Anxiety about the course/end-state of the disease, hopelessness; Positive psychological functioning; Situations triggering or enhancing breathing problems; Symptoms; Activity; Impact. CONCLUSIONS: The 46-item COPD-SIB has good psychometric properties and content validity. Items are available in Dutch and English. The COPD-SIB can be used as a stand-alone instrument, or to inform computerised adaptive testing.

Identifying key domains of health-related quality of life for patients with chronic obstructive pulmonary disease: interviews with healthcare professionals.

PURPOSE: The aim of this paper is to identify which domains of health-related quality of life (HRQoL) are most important for patients with chronic obstructive pulmonary disease (COPD), from the perspective of healthcare professionals (HCPs). METHODS: Thirteen Dutch HCPs [six pulmonologists, three pulmonology nurse practitioners, two physiotherapists and two general practitioners; 9 men; mean age 51.0 (SD = 10.6) years; mean years of experience 12.1 (SD = 7.2)] specialized in the field of COPD were recruited. The only inclusion criterion was that the HCP had to have extensive experience in treating COPD patients. The face-to-face interviews took 30-40 min. RESULTS: Physical health emerged as the most important theme from the spontaneous statements that HCPs made when asked about HRQoL in relation to COPD, closely followed by social health and coping with COPD-related complaints and restrictions. The most frequently selected PROMIS domains were fatigue, physical function, emotional support and depression. If the related domains satisfaction with participation in social roles and activities and ability to participate in social roles and activities were to be combined, it would come in second place after fatigue. CONCLUSION: When comparing the domains chosen by HCPs to the ones chosen by patients in a recent study, there is a high degree of agreement, with the exception of depression. We argue that it is important to take into account both patient and HCP perspective when developing/selecting HRQoL instruments. Our results may be used to inform domain selection to measure HRQoL in patients with COPD, as well as instrument development.

Identifying key domains of health-related quality of life for patients with chronic obstructive pulmonary disease: the patient perspective.

BACKGROUND: Numerous instruments are available to measure health-related quality of life (HRQoL) in patients with Chronic Obstructive Pulmonary Disease (COPD), covering a wide array of domains ranging from symptoms such as dyspnea, cough and wheezing, to social and emotional functioning. Currently no information or guide is available yet to aid the selection of domains for a particular study or disease population. The aim of this paper is to identify which domains of HRQoL are most important with respect to COPD, from the patient perspective. METHODS: Twenty-one Dutch patients with COPD were asked to describe important domains impacted by COPD freely; second, they were presented with cues (domains from the Patient-Reported Outcomes Measurement Information System (PROMIS) framework) and were asked to select the domains that were most relevant to them. During the interview, the patients were asked to indicate in which way the selected domains impact their lives. Both the answers to the open question, and the patient statements motivating nomination of PROMIS domains were coded into themes. RESULTS: The most relevant (sub)domains of HRQoL for patients with COPD were: physical health (fatigue, physical functioning), social health (instrumental support, ability to participate in social roles and activities, companionship, and emotional support), and coping with COPD. CONCLUSION: We identified which domains of HRQoL are most important to patients with COPD. One of these (coping with COPD) is not explicitly covered by PROMIS, or by traditional questionnaires that are used to measure HRQoL in COPD.

The Norwegian traumatic grief inventory-self report plus (TGI-SR+): a psychometric evaluation in traumatically bereaved people.

Background: Prolonged grief disorder (PGD) has been added to the ICD-11 and DSM-5-TR. The Traumatic Grief Inventory-Self Report Plus (TGI-SR+) assesses self-rated PGD intensity as defined in ICD-11 and DSM-5-TR. The TGI-SR + is available in multiple languages, but has not been validated yet in Norwegian.Objective: The aim of this study was to evaluate the psychometric properties of the Norwegian TGI-SR + .Method: Bereaved adults (N = 307) whose child or sibling died ≥6 months ago due to a sudden or violent loss completed the TGI-SR + and measures for posttraumatic stress, depression, and precursor PGD symptoms. We examined the factor structure and internal consistency of the ICD-11 and DSM-5-TR PGD items. Convergent validity and known-groups validity was evaluated. Probable PGD cases, pair-wise agreement between diagnostic scoring rules for both PGD criteria-sets, and cut-off scores were calculated.Results: The 1-factor model for ICD-11 and DSM-5-TR PGD showed the best fit and demonstrated good internal consistency. Convergent validity was supported by strong associations between summed ICD-11 and DSM-5-TR PGD scores and summed posttraumatic stress, depression, and precursor prolonged grief scores. Known-groups validity was supported by PGD intensity being related to educational level and time since loss. The perfect pair-wise agreement was reached using the ICD-11 and DSM-5-TR PGD diagnostic scoring rules. The optimal cut-off score for detecting probable PGD cases, when summing all TGI-SR + items, was ≥73.Conclusions: The Norwegian TGI-SR + seems a valid and reliable instrument to assess ICD-11 and DSM-5-TR PGD intensity after losing a child or sibling under traumatic circumstances.

The TGI-SR + is a self-report instrument assessing ICD-11 and DSM-5-TR prolonged grief disorder intensity.The Norwegian TGI-SR + seems to be a valid and reliable instrument to assess prolonged grief disorder intensity.Optimal cut-off for detecting probable prolonged grief disorder cases is ≥73 in this traumatically bereaved sample of parents and siblings.

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.

Traumatic stress researchers worldwide responding to a survey held generally positive views on data sharing, endorsing scholarly altruism and pro-sharing ethical considerations, and rating data re-use as useful for advancing the field.While many respondents reported instances of sharing or re-using data, gold standard practices such as formally depositing data in established repositories were reported as infrequent.Barriers to data sharing and re-use included time constraints, funding, and a lack of familiarity with practices to make data more Findable, Accessible, Interoperable, and Re-usable (FAIR).
