A prospective study of pre-trauma risk factors for post-traumatic stress disorder and depression

Social support utilization's effect on post-traumatic stress symptoms: a Danish cross-sectional study of 383 ambulance personnel

Introduction

Social support is considered an important factor in prevention of mental illness. However, little is known about the association between ambulance personnel's use of multiple types of social support and post-traumatic stress symptoms (PTSS). This study aims to assess if number of used social support types predicts PTSS for ambulance personnel. Apart from assessing the main effect of social support utilization, we were interested in investigating if social support utilization moderated the effect of frequency of critical events on PTSS.

Materials and methods

A total of 383 ambulance personnel completed a survey consisting of validated questionnaires. Hierarchical multiple linear regression analyses were performed to assess the association between frequency of traumatic exposure and utilization of social support and PTSS as outcome variable.

Results

Higher number of utilized social support types was associated with higher levels of PTSS (β = 0.15, p <.001). When serving as a moderator of the association between frequency of exposure to critical incidents and PTSS, social support utilization had a significant and positive interaction effect (β = 0.26, p = .049). 307 participants had used 2 or 3 types of informal support during the past year, whereas 81 had used 2 or 3 types of formal support.

Conclusion

To our knowledge, this is the first study investigating the relationship between utilization of multiple, concurrent social support types and PTSS. This study suggests that to understand the effects of social support among ambulance personnel, it is necessary to assess the utilization of multiple concurrent support types, contributing factors to social support use, and different patterns of social support utilization that constitutes professional life in ambulance work.

Care Under Pressure 2: a realist synthesis of causes and interventions to mitigate psychological ill health in nurses, midwives and paramedics

BACKGROUND

Nurses, midwives and paramedics comprise over half of the clinical workforce in the UK National Health Service and have some of the highest prevalence of psychological ill health. This study explored why psychological ill health is a growing problem and how we might change this.

METHODS

A realist synthesis involved iterative searches within MEDLINE, CINAHL and HMIC, and supplementary handsearching and expert solicitation. We used reverse chronological quota screening and appraisal journalling to analyse each source and refine our initial programme theory. A stakeholder group comprising nurses, midwives, paramedics, patient and public representatives, educators, managers and policy makers contributed throughout.

RESULTS

Following initial theory development from 8 key reports, 159 sources were included. We identified 26 context-mechanism-outcome configurations, with 16 explaining the causes of psychological ill health and 10 explaining why interventions have not worked to mitigate psychological ill health. These were synthesised to five key findings: (1) it is difficult to promote staff psychological wellness where there is a blame culture; (2) the needs of the system often over-ride staff psychological well-being at work; (3) there are unintended personal costs of upholding and implementing values at work; (4) interventions are fragmented, individual-focused and insufficiently recognise cumulative chronic stressors; and (5) it is challenging to design, identify and implement interventions.

CONCLUSIONS

Our final programme theory argues the need for healthcare organisations to rebalance the working environment to enable healthcare professionals to recover and thrive. This requires high standards for patient care to be balanced with high standards for staff psychological well-being; professional accountability to be balanced with having a listening, learning culture; reactive responsive interventions to be balanced by having proactive preventative interventions; and the individual focus balanced by an organisational focus.

Can an intervention designed to reduce repetitive negative thinking alter the response to a psychosocial stressor? A randomized controlled study

Prior research suggests that repetitive negative thinking (RNT) negatively impacts mental health by intensifying and prolonging emotional reactivity to stress. This study investigated whether an intervention designed to reduce RNT alters emotional reactivity. Young adults with high trait RNT (N = 79) were randomly allocated to an RNT-focused intervention (smartphone app-based, 10 days) or a waiting list before exposure to a standardized stressor. The pre-registered analysis did not reveal a significant condition * time interaction for negative affect. However, exploratory analyses showed that whilst initial increases in negative affect in response to the stressor did not differ between conditions, participants in the intervention condition reported less negative affect throughout the following recovery phase. Additionally, participants in the intervention condition appraised their ability to cope with the stressor as higher and reported less RNT in the recovery phase. In contrast, the intervention did not affect biological stress responses. The findings indicate that RNT-focused interventions might have positive effects on mental health by breaking the self-reinforcing cycle of RNT, negative affect and maladaptive appraisals in response to stress. However, as findings are partly based on exploratory analyses, further research is needed to confirm whether reduced subjective stress reactivity mediates the effects of RNT-focused interventions on psychopathological symptoms.

Post-traumatic stress disorder: the role of the amygdala and potential therapeutic interventions - a review

Introduction

Post-traumatic stress disorder (PTSD) is a psychiatric disorder triggered by exposure to a life-threatening or sexually violent traumatic event, and is characterized by symptoms involving intrusive re-experiencing, persistent avoidance of associated stimuli, emotional and cognitive disturbances, and hyperarousal for long periods after the trauma has occurred. These debilitating symptoms induce occupational and social impairments that contribute to a significant clinical burden for PTSD patients, and substantial socioeconomic costs, reaching approximately $20,000 dollars per individual with PTSD each year in the US. Despite increased translational research focus in the field of PTSD, the development of novel, effective pharmacotherapies for its treatment remains an important unmet clinical need.

Observations

In this review, we summarize the evidence implicating dysfunctional activity of the amygdala in the pathophysiology of PTSD. We identify the transient receptor potential canonical (TRPC) ion channels as promising drug targets given their distribution in the amygdala, and evidence from animal studies demonstrating their role in fear response modulation. We discuss the evidence-based pharmacotherapy and psychotherapy treatment approaches for PTSD.

Discussion

In view of the prevalence and economic burden associated with PTSD, further investigation is warranted into novel treatment approaches based on our knowledge of the involvement of brain circuitry and the role of the amygdala in PTSD, as well as the potential added value of combined pharmacotherapy and psychotherapy to better manage PTSD symptoms.

Sleep, mental health and physical health in new shift workers transitioning to shift work: Systematic review and meta-analysis

This systematic review and meta-analysis (PROSPERO registration CRD42022309827) aimed to describe how shift work impacts new workers' sleep, mental health, and physical health during the transition to shift work and to consolidate information regarding predictors of shift work tolerance (SWT) during this transition period. Inclusion criteria included: new shift workers; sleep, mental health, or physical health outcomes; prospective study design with the first timepoint assessing workers within three months of starting shift work; and written in English. Searches from six databases returned 12,172 articles as of August 2023. The final sample included 48 papers. Publication quality and risk of bias was assessed using the critical appraisal skills program. Forty-five studies investigated longitudinal changes in sleep, mental health, or physical health outcomes and 29 studies investigated predictors of SWT (i.e., better sleep, mental and physical health). Sleep and mental health outcomes worsened following the onset of shift work, while physical health did not significantly change. Pre-shift work mental health, sleep, and work characteristics predicted SWT later in workers' careers. Shift work adversely impacts new workers' sleep and mental health early in their career, and interventions before beginning shift work are needed to promote better SWT.

Relationship between anxiety sensitivity and post-traumatic stress symptoms in trauma-exposed adults: A meta-analysis

Given the high rate of trauma exposure among the general population, it is important to delineate the risk factors for post-traumatic stress disorder (PTSD). While historically implicated in panic disorder, anxiety sensitivity is increasingly found to play a role in PTSD. The present review investigated the size of the relationship between anxiety sensitivity and PTSD symptoms among trauma exposed adults. A systematic search on multiple electronic databases (PTSDpubs, CINAHL, MEDLINE and PsycINFO) generated a total of 1025 records, among which 52 (n = 15173) met study inclusion criteria and were included in our random effects meta-analysis. Our results indicated a medium effect size (r = .46, 95% CI =.41,.50) for the relationship between anxiety sensitivity and PTSD symptoms. There was significant between-study heterogeneity. Furthermore, sub-group analyses revealed that study design (cross-sectional vs. longitudinal) may significantly moderate the association between anxiety sensitivity and PTSD severity. No moderation effect was found for assessment of PTSD through interview versus questionnaire, interpersonal versus non-interpersonal trauma, or low versus high study quality. Such patterns of results are consistent with cognitive models of PTSD. Clinical implications, strengths and limitations of the review were discussed.

Causes and solutions to workplace psychological ill-health for nurses, midwives and paramedics: the Care Under Pressure 2 realist review

Background

Nurses, midwives and paramedics are the largest collective group of clinical staff in the National Health Service and have some of the highest prevalence of psychological ill-health. Existing literature tends to be profession-specific and focused on individual interventions that place responsibility for good psychological health with nurses, midwives and paramedics themselves.

Aim

To improve understanding of how, why and in what contexts nurses, midwives and paramedics experience work-related psychological ill-health; and determine which high-quality interventions can be implemented to minimise psychological ill-health in these professions.

Methods

Realist synthesis methodology consistent with realist and meta-narrative evidence syntheses: evolving standards' reporting guidelines.

Data sources

First round database searching in Medical Literature Analysis and Retrieval System Online Database ALL (via Ovid), cumulative index to nursing and allied health literature database (via EBSCO) and health management information consortium database (via Ovid), was undertaken between February and March 2021, followed by supplementary searching strategies (e.g. hand searching, expert solicitation of key papers). Reverse chronology screening was applied, aimed at retaining 30 relevant papers in each profession. Round two database searches (December 2021) targeted COVID-19-specific literature and literature reviews. No date limits were applied.

Results

We built on seven key reports and included 75 papers in the first round (26 nursing, 26 midwifery, 23 paramedic) plus 44 expert solicitation papers, 29 literature reviews and 49 COVID-19 focused articles in the second round. Through the realist synthesis we surfaced 14 key tensions in the literature and identified five key findings, supported by 26 context mechanism and outcome configurations. The key findings identified the following: (1) interventions are fragmented, individual-focused and insufficiently recognise cumulative chronic stressors; (2) it is difficult to promote staff psychological wellness where there is a blame culture; (3) the needs of the system often override staff well-being at work ('serve and sacrifice'); (4) there are unintended personal costs of upholding and implementing values at work; and (5) it is challenging to design, identify and implement interventions to work optimally for diverse staff groups with diverse and interacting stressors.

Conclusions

Our realist synthesis strongly suggests the need to improve the systemic working conditions and the working lives of nurses, midwives and paramedics to improve their psychological well-being. Individual, one-off psychological interventions are unlikely to succeed alone. Psychological ill-health is highly prevalent in these staff groups (and can be chronic and cumulative as well as acute) and should be anticipated and prepared for, indeed normalised and expected. Healthcare organisations need to (1) rebalance the working environment to enable healthcare professionals to recover and thrive; (2) invest in multi-level system approaches to promote staff psychological well-being; and use an organisational diagnostic framework, such as the NHS England and NHS Improvement Health and Wellbeing framework, to self-assess and implement a systems approach to staff well-being.

Future work

Future research should implement, refine and evaluate systemic interventional strategies. Interventions and evaluations should be co-designed with front-line staff and staff experts by experience, and tailored where possible to local, organisational and workforce needs.

Limitations

The literature was not equivalent in size and quality across the three professions and we did not carry out citation searches using hand searching and stakeholder/expert suggestions to augment our sample.

Changes in cognitive processes and coping strategies precede changes in symptoms during cognitive therapy for posttraumatic stress disorder

Theories of posttraumatic stress disorder (PTSD) highlight the role of cognitive and behavioral factors in its development, maintenance, and treatment. This study investigated the relationship between changes in factors specified in Ehlers and Clark's (2000) model of PTSD and PTSD symptom change in 217 patients with PTSD who were treated with cognitive therapy for PTSD (CT-PTSD) in routine clinical care. Bivariate latent change score models (LCSM) of session-by-session changes in self-report measures showed that changes in PTSD symptoms were preceded by changes in negative appraisals, flashback characteristics of unwanted memories, safety behaviours, and unhelpful responses to intrusions, but not vice versa. For changes in trauma memory disorganization and PTSD symptoms we found a bidirectional association. This study provides evidence that cognitive and behavioral processes proposed in theoretical models of PTSD play a key role in driving symptom improvement during CT-PTSD.

Trauma Matters: Integrating Genetic and Environmental Components of PTSD

Trauma is ubiquitous, but only a subset of those who experience trauma will develop posttraumatic stress disorder (PTSD). In this review, it is argued that to determine who is at risk of developing PTSD, it is critical to examine the genetic etiology of the disorder and individual trauma profiles of those who are susceptible. First, the state of current PTSD genetic research is described, with a particular focus on studies that present evidence for trauma type specificity, or for differential genetic etiology according to gender or race. Next, approaches that leverage non-traditional phenotyping approaches are reviewed to identify PTSD-associated variants and biology, and the relative advantages and limitations inherent in these studies are reflected on. Finally, it is discussed how trauma might influence the heritability of PTSD, through type, risk factors, genetics, and associations with PTSD symptomology.

Sleep and mental health in recruit paramedics: a 6-month longitudinal study

STUDY OBJECTIVES

To explore potential relationships and longitudinal changes in sleep and mental health in recruit paramedics over the first 6 months of work, and whether sleep disturbances pre-emergency work predict future mental health outcomes.

METHODS

Participants (N = 101, 52% female, Mage = 26 years) completed questionnaires prior to (baseline), and after 6 months of emergency work to assess for symptoms of insomnia, obstructive sleep apnea, post-traumatic stress disorder (PTSD), depression, anxiety, and trauma exposure. At each timepoint, participants also completed a sleep diary and wore an actigraph for 14 days to assess sleep patterns. Correlations between baseline sleep and mental health were conducted and changes in these variables across timepoints were examined using linear mixed models. Hierarchical regressions assessed whether sleep at baseline predicted mental health at follow-up.

RESULTS

Insomnia and depression symptoms, and total sleep time increased while sleep onset latency decreased across the first 6 months of emergency work. Participants experienced an average of 1 potentially traumatic event during the 6-month period. Baseline insomnia predicted increased depression symptoms at the 6-month follow-up, while baseline wake after sleep onset predicted follow-up PTSD symptoms.

CONCLUSION

Results highlight an increase in insomnia and depression across the initial months of emergency work, while sleep disturbances before emergency work were identified as potential risk factors for the development of depression and PTSD among paramedics in their early career. Screening and early interventions targeting poor sleep at the beginning of emergency employment may assist in reducing the risk of future mental health outcomes in this high-risk occupation.

Post-traumatic Stress Disorder and Its Associated Risk Factors Among Emergency Healthcare Workers: A Saudi Cross-Sectional Analytical Study

BACKGROUND

Post-traumatic stress disorder (PTSD) is a psychiatric disease characterized by exposure to threatened death or serious injury and directly experiencing or witnessing the event. Many healthcare professionals have had PTSD, but emergency physicians may be particularly susceptible. To our knowledge, no study has been performed in Saudi Arabia to identify the prevalence and associated risk factors of PTSD among emergency staff.

OBJECTIVE

This study aims to determine the prevalence and risk factors of post-traumatic stress disorder (PTSD) among emergency healthcare workers (HCWs) in Saudi Arabia.

METHODS

A cross-sectional analytical study will be conducted in emergency departments around Saudi Arabia in all regions. The study population will include healthcare workers in emergency departments who work and presently live in Saudi Arabia. The survey was divided into two sections. The first section focuses on the emergency personnel's demographic data; the second concentrates on screening for post-traumatic stress disorder using the PTSD checklist for DSM-5 (PCL-5).

RESULTS

Our population included 519 emergency healthcare staff, including males (51.4%) and females (48.6%). Most emergency HCWs worked in the Ministry of Health Hospitals (58%). The highest diagnosed psychological disorders among emergency staff were anxiety (19.3%) and mood disorders (10.2%). The prevalence of PTSD among emergency workers in Saudi Arabia was 14.1%. The prevalence of PTSD was significantly higher among emergency HCWs who had chronic diseases, emergency workers with anxiety or mood disorders, emergency staff who were using psychiatric medication (p<0.001), and those with psychotic disorders (p=0.002).

CONCLUSION

The prevalence of PTSD among emergency healthcare workers in Saudi Arabia is estimated to be 14.1%, and pre-existing mental illnesses are associated with a higher risk of PTSD.

Sex-specific risk and resilience correlates of suicidal ideation in U.S. military veterans

OBJECTIVES

To estimate the prevalence and identify gender-specific risk factors associated with suicidal ideation (SI) in a nationally representative sample of U.S. military veterans.

METHODS

Data were analyzed from the 2019-2020 National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of 4069 veterans. Bivariate and multivariable analyses were conducted to identify factors associated with SI in male and female veterans.

RESULTS

The prevalence of SI was significantly higher in female than male veterans (18.1 % vs. 11.2 %). In female veterans, results of a relative importance analysis revealed that the majority of explained variance in SI (Nagelkerke R² = 0.54) was accounted for by lower psychological resilience (44.4 %), and history of non-suicidal self-injury (24.4 %) and alcohol use disorder (20.6 %). In male veterans, the majority of explained variance in SI (Nagelkerke R² = 0.32) was accounted for by higher loneliness (19.5 %) and hostility (19.1 %), and lower purpose in life (16.3 %).

CONCLUSIONS

Suicidal ideation is prevalent among U.S. veterans, particularly in female veterans. Different risk factors emerged as strong correlates of SI in female and male veterans, which may be used to inform gender-specific suicide prevention and treatment efforts in this population.

Perspectives on resilience: Trait resilience, correlates of resilience in daily life, and longer-term change in affective distress

Resilience describes successful adaptation in the face of adversity, commonly inferred from trajectories of well-being following major life events. Alternatively, resilience was conceptualised as a psychological trait, facilitating adaptation through stable individual characteristics. Both perspectives may relate to individual differences in how stress is regulated in daily life. In the present study, we combined these perspectives on resilience. Our sample consisted of N = 132 middle-aged adults, who experienced major life events in between two waves of a longitudinal study. We implemented latent change regression models to predict change in affective distress. As predictors, we investigated trait resilience and correlates of resilience in daily life (stressor occurrence, stress reactivity, positive reappraisal, mindful attention, and acceptance), measured using experience sampling (T = 70 occasions). Unexpectedly, trait resilience was not associated with change in distress. In contrast, resilience correlates in daily life, most notably lower stress reactivity, were associated with more favourable change. Higher trait resilience related to higher average mindfulness, higher reappraisal, and lower negative affect. Overall, while trait resilience translated into everyday correlates of resilience, it was not predictive of changes in affective distress. Instead, precursors of changes in well-being may be found in correlates of resilience in daily life.

Web-Based Mind-Body Tactical Resilience Training Program for First Responders: Pre-Post Study Assessing Feasibility, Acceptability, and Usability

BACKGROUND

First responders report elevated rates of mental disorders, including posttraumatic stress disorder (PTSD), yet many are reluctant to seek care. Preventative resilience training programs attempt to proactively address this issue, and there is evidence showing promise for programs targeting cognitive processes. However, these programs rarely address the physical health conditions associated with PTSD. There is emerging evidence of mind-body exercise training improving PTSD symptoms as well as its associated physical health symptoms. However, the feasibility and acceptability of delivering a web-based mind-body resilience training among first responders are not yet known.

OBJECTIVE

This study aimed to evaluate the feasibility, usability, and acceptability of a web-based mind-body tactical resilience training program designed for first responders. In addition, we explored the preliminary effectiveness of the training program on mental health outcomes, adaptive cognitive strategies, and work productivity.

METHODS

A total of 42 first responders based in the United States enrolled in the web-based training program. Participants were administered web-based surveys before enrolling in the 6-week web-based program and at the end of the program. The primary outcomes of feasibility were measured using the number of training hours, program adherence rates, and self-reported data on frequency of practice. Acceptability and usability were measured using self-reported data. Secondary outcomes were symptoms of PTSD, psychological distress, emotion regulation, stress mindset, psychological preparedness, and work performance.

RESULTS

Overall, the training program was feasible based on the median number of training hours spent on the web-based program (7.57 hours out of an expected total of 6 to 9 hours), and 55% (23/42) of the enrolled participants completed more than half of the program. Although acceptability, usability, and frequency of practice were rated as high, this was based on only 29% (12/42) of the respondents who provided follow-up data. Secondary outcomes showed a significant improvement in the adaptive cognitive strategy of the stress mindset, with a mean difference of -5.42 (SD 4.81; 95% CI -8.475 to -2.358; t₁₁=-3.898; P=.002). All other secondary outcomes were not significant. However, the secondary outcomes were exploratory only, and this study was neither designed nor powered to adequately assess efficacy.

CONCLUSIONS

These findings suggest that a mind-body tactical resilience training program delivered in a web-based format is feasible and acceptable among first responders; however, further refinements may be required to improve adherence rates. Further research using a larger, more rigorous trial design is warranted to examine the effectiveness of this type of training as a possible prevention or treatment strategy for this population.

Mental health risk factors for shift work disorder in paramedics: A longitudinal study

OBJECTIVES

Depression and anxiety are prominent in paramedics, as is the prevalence of shift work disorder (SWD), a circadian sleep condition comorbid with mental health disorders. However, the role of mental health risk factors for SWD is largely unknown. This study investigated whether mental health levels in recruit paramedics before shift work predicted greater risk of SWD at 6-months into their career and explored whether shift and sleep factors mediated this relationship.

DESIGN

A longitudinal study.

SETTING

Victoria, Australia.

PARTICIPANTS

Recruit paramedics were assessed at baseline (n = 101; ie, pre-shift work) and after 6-months (n = 93) of shift and emergency work.

MEASUREMENTS

At both time points, participants completed self-reported measures of depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder Questionnaire-7), and SWD (SWD-Screening Questionnaire). Participants also filled a sleep and work diary for 14-days at each timepoint.

RESULTS

After 6-months of emergency work 21.5% of paramedics had a high SWD risk. Logistic regression models showed baseline depression predicted 1.24-times greater odds for SWD at 6-months. Through Lavaan path analysis we found shift and sleep variables did not mediate the relationship between baseline mental health and SWD risk. Baseline depression was associated with increased sleepiness levels following paramedics' major sleep periods at 6-months. Pre-existing depression levels also predicted greater perceived nightshift workload.

CONCLUSIONS

Our results highlight depression symptoms before emergency work are a risk factor for SWD within 6-months of work. Depression represents a modifiable risk factor amenable to early interventions to reduce paramedics' risk of SWD.

Residual risks of comorbidities after parathyroidectomy in a nationwide cohort of patients with primary hyperparathyroidism

PURPOSE

Primary hyperparathyroidism (PHPT) is a common endocrine disorder with increasing incidence, while epidemiologic data in Asian population has been lacking. Therefore, we aimed to identify the incidence, prognosis, and prognostic factors of PHPT patients who underwent parathyroidectomy in Korea.

METHODS

In this retrospective nationwide cohort, patients with PHPT were defined as those with diagnostic codes of PHPT and procedural codes for parathyroidectomy, excluding chronic renal failure or secondary hyperparathyroidism based on National Health Insurance Services database in Korea in 2002-2018. Main primary outcomes were all-cause mortality, cardiovascular, and cerebrovascular events.

RESULTS

A total of 5561 patients were diagnosed with PHPT and had parathyroidectomy. The mean age was 54.5 years, and 71.8% were women. The age-standardized incidence was 10.1/100,000 person-year in 2018, rising from 1.7/100,000 person-year in 2002. During a mean of 5.9 years, history of cardiovascular disease, mood disorder, and genitourinary stone had increased risks of mortality with hazard ratios (HRs) of 1.59 (95% confidence interval [CI] 1.10-2.29), 1.43 (CI 1.14-1.80), and 1.40 (CI 1.09-1.80), respectively. History of hypertension, cerebrovascular disease, diabetes mellitus, and mood disorder were risk factors for cardiovascular events with HRs of 1.42 (CI 1.22-1.66), 1.29 (CI 1.05-1.58), 1.22 (CI 1.07-1.40), and 1.14 (CI 1.00-1.29), respectively. Mood disorder was a significant risk factor for cerebrovascular events (HR 1.30, CI 1.11-1.52).

CONCLUSION

The incidence of PHPT patients who underwent parathyroidectomy has been rising in Korea as reported in other countries. Patients with complications, especially mood disorder, had increased cardiovascular and cerebrovascular events and mortality risks.

Assessing the impact of the Royal Canadian Mounted Police (RCMP) protocol and Emotional Resilience Skills Training (ERST) among diverse public safety personnel

BACKGROUND

Public safety personnel (PSP; e.g., border services personnel, correctional workers, firefighters, paramedics, police, public safety communicators) are frequently exposed to potentially psychologically traumatic events. Such events contribute to substantial and growing challenges from posttraumatic stress injuries (PTSIs), including but not limited to posttraumatic stress disorder.

METHODS

The current protocol paper describes the PSP PTSI Study (i.e., design, measures, materials, hypotheses, planned analyses, expected implications, and limitations), which was originally designed to evaluate an evidence-informed, proactive system of mental health assessment and training among Royal Canadian Mounted Police for delivery among diverse PSP (i.e., firefighters, municipal police, paramedics, public safety communicators). Specifically, the PSP PTSI Study will: (1) adapt, implement, and assess the impact of a system for ongoing (i.e., annual, monthly, daily) evidence-based assessments; (2) evaluate associations between demographic variables and PTSI; (3) longitudinally assess individual differences associated with PTSI; and, (4) assess the impact of providing diverse PSP with a tailored version of the Emotional Resilience Skills Training originally developed for the Royal Canadian Mounted Police in mitigating PTSIs based on the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders. Participants are assessed pre- and post-training, and then at a follow-up 1-year after training. The assessments include clinical interviews, self-report surveys including brief daily and monthly assessments, and daily biometric data. The current protocol paper also describes participant recruitment and developments to date.

DISCUSSION

The PSP PTSI Study is an opportunity to implement, test, and improve a set of evidence-based tools and training as part of an evidence-informed solution to protect PSP mental health. The current protocol paper provides details to inform and support translation of the PSP PTSI Study results as well as informing and supporting replication efforts by other researchers.

The mental health impact of COVID-19-related stressors among treatment-seeking trauma-exposed veterans

Trauma-exposed veterans receiving mental health care may have an elevated risk of experiencing COVID-19-related difficulties. Using data from several ongoing clinical trials (N = 458), this study examined exposure to COVID-19-related stressors and their associations with key sociodemographic factors and mental health outcomes. The results showed that exposure to COVID-19-related stressors was common, higher among veterans who were racial/ethnic minorities d = 0.32, and associated with elevated posttraumatic stress disorder (PTSD), r = .288, and depressive symptom severity, r = .246. Women veterans experienced more difficulty accessing social support, d = 0.31, and higher levels of COVID-19-related distress, d = 0.31, than men. Qualitative data were consistent with survey findings and highlighted the broader societal context in veterans' experience of COVID-19-related distress. These findings may inform future research on the impact of the pandemic on veterans, particularly those who are women and members of minoritized racial/ethnic groups, as well as mental health treatment planning for this population.

Testifying after an Investigation: Shaping the Mental Health of Public Safety Personnel

In this editorial, we draw on two Canadian cases to interrogate how mass causality events and investigations consume many responders before (e.g., public safety communicators, detachment service assistants), during (e.g., police, fire, paramedics), and after the incident (e.g., coroners, correctional workers, media coverage). Their well-being may suffer from the associated processes and outcomes. In the current article, we focus on the mass causality incident of 2020 in Nova Scotia, Canada, and the investigation following a prisoner death in 2019 in Newfoundland, Canada, to explore how testifying post-incident can be made more palatable for participating public safety personnel (PSP). Specifically, we study how testifying after an adverse event can affect PSP (e.g., recalling, vicarious trauma, triggers) and how best to mitigate the impact of testimony on PSP well-being, with a lens to psychological "recovery" or wellness. We focus here on how to support those who may have to testify in a judicial proceeding or official inquiry, given being investigated for best-intended actions can result in moral injury or a posttraumatic stress injury, both exacerbated by judicial review, charge, accusation, or inquiry.

Comparing the Psychological Effects of Manikin-Based and Augmented Reality-Based Simulation Training: Within-Subjects Crossover Study

BACKGROUND

Patient simulators are an increasingly important part of medical training. They have been shown to be effective in teaching procedural skills, medical knowledge, and clinical decision-making. Recently, virtual and augmented reality simulators are being produced, but there is no research on whether these more realistic experiences cause problematic and greater stress responses as compared to standard manikin simulators.

OBJECTIVE

The purpose of this research is to examine the psychological and physiological effects of augmented reality (AR) in medical simulation training as compared to traditional manikin simulations.

METHODS

A within-subjects experimental design was used to assess the responses of medical students (N=89) as they completed simulated (using either manikin or AR) pediatric resuscitations. Baseline measures of psychological well-being, salivary cortisol, and galvanic skin response (GSR) were taken before the simulations began. Continuous GSR assessments throughout and after the simulations were captured along with follow-up measures of emotion and cortisol. Participants also wrote freely about their experience with each simulation, and narratives were coded for emotional word use.

RESULTS

Of the total 86 medical students who participated, 37 (43%) were male and 49 (57%) were female, with a mean age of 25.2 (SD 2.09, range 22-30) years and 24.7 (SD 2.08, range 23-36) years, respectively. GSR was higher in the manikin group adjusted for day, sex, and medications taken by the participants (AR-manikin: -0.11, 95% CI -0.18 to -0.03; P=.009). The difference in negative affect between simulation types was not statistically significant (AR-manikin: 0.41, 95% CI -0.72 to 1.53; P=.48). There was no statistically significant difference between simulation types in self-reported stress (AR-manikin: 0.53, 95% CI -2.35 to 3.42; P=.71) or simulation stress (AR-manikin: -2.17, 95% CI -6.94 to 2.59; P=.37). The difference in percentage of positive emotion words used to describe the experience was not statistically significant between simulation types, which were adjusted for day of experiment, sex of the participants, and total number of words used (AR-manikin: -4.0, 95% CI -0.91 to 0.10; P=.12). There was no statistically significant difference between simulation types in terms of the percentage of negative emotion words used to describe the experience (AR-manikin: -0.33, 95% CI -1.12 to 0.46; P=.41), simulation sickness (AR-manikin: 0.17, 95% CI -0.29 to 0.62; P=.47), or salivary cortisol (AR-manikin: 0.04, 95% CI -0.05 to 0.13; P=.41). Finally, preexisting levels of posttraumatic stress disorder, perceived stress, and reported depression were not tied to physiological responses to AR.

CONCLUSIONS

AR simulators elicited similar stress responses to currently used manikin-based simulators, and we did not find any evidence of AR simulators causing excessive stress to participants. Therefore, AR simulators are a promising tool to be used in medical training, which can provide more emotionally realistic scenarios without the risk of additional harm.

The Royal Canadian Mounted Police (RCMP) Study: protocol for a prospective investigation of mental health risk and resilience factors

The Royal Canadian Mounted Police (RCMP), like all public safety personnel (PSP), are frequently exposed to potentially psychologically traumatic events that contribute to posttraumatic stress injuries (PTSI). Addressing PTSI is impeded by the limited available research. In this protocol paper, we describe the RCMP Study, part of the concerted efforts by the RCMP to reduce PTSI by improving access to evidence-based assessments, treatments and training as well as participant recruitment and RCMP Study developments to date. The RCMP Study has been designed to (1) develop, deploy and assess the impact of a system for ongoing annual, monthly and daily evidence-based assessments; (2) evaluate associations between demographic variables and PTSI; (3) longitudinally assess individual differences associated with PTSI; (4) augment the RCMP Cadet Training Program with skills to proactively mitigate PTSI; and (5) assess the impact of the augmented training condition (ATC) versus the standard training condition (STC). Participants in the STC (n = 480) and ATC (n = 480) are assessed before and after training and annually for 5 years on their deployment date; they also complete brief monthly and daily surveys. The RCMP Study results are expected to benefit the mental health of all participants, RCMP and PSP by reducing PTSI among all who serve.

The Quality of Life and the Bio-Molecular Profile in Working Environment: A Systematic Review

Working life is characterised by various requirements and degrees of control in meeting these demands. The imbalance of these elements with workers’ resources can result in work-related stress involving the repeated activation of stress response systems. Modifications in the bio-molecular profile may represent a biological signature of individuals’ life experiences and provide evidence on pathways through which such stressors can result in health outcomes. The aim of our systematic review is to characterize the quality of life (QOL) and the bio-molecular profile in the working population, to highlight if the alteration observed might be related to the working conditions. The article query was performed on PubMed, Embase, and Cochrane CENTRAL and results have been presented according to three molecular pathways involved in the stress response: oxidative stress, inflammation, and neuroendocrine activation. The epidemiological sample has been sub-grouped into “clinical” and “non-clinical” populations according to the presence of a diagnosis of psychological disorders. Besides some critical issues, the review highlights the importance of developing a valid array of biological indicators, measurable in non-invasive matrices, sensitive to both derangements from physiological conditions and stress reduction, useful for identifying those groups at higher risk of health outcomes and, eventually, promoting workers’ wellbeing.

Effects of Sleep Deficiency on Risk, Course, and Treatment of Psychopathology

This article reviews the literature on the relationship between sleep deficiency and unipolar and bipolar depression, anxiety disorders, and posttraumatic stress disorder. We consider the evidence for sleep as a contributory causal factor in the development of psychiatric disorders, as well as sleep as an influential factor related to the outcome and recurrence of psychopathology. A case for sleep deficiency being an important treatment target when sleep and psychiatric disorders are comorbid is also made. Our recommendation is that sleep deficiency is recognized as a means to positively impact the development and course of psychopathology and, as such, is routinely assessed and treated in clinical practice.

Emotional processing prospectively modulates the impact of anxiety on COVID-19 pandemic-related post-traumatic stress symptoms: an ERP study

BACKGROUND

Considering that the elevated distress caused by the COVID-19 pandemic, in some cases, led to post-traumatic stress symptoms (PTSS), it has been proposed as a specific traumatic event. The present longitudinal study investigated pre-pandemic motivated attention to emotional stimuli, as indexed by Late Positive Potential (LPP) amplitude, in relation with the potential differential role of anxiety and depressive symptoms in predicting PTSS severity related to the COVID-19 pandemic.

METHODS

A total of 79 university students initially completed self-report measures of depression and anxiety along with a passive viewing task of emotional (pleasant, unpleasant) and neutral pictures while electroencephaloghic activity was recorded. In December 2020, 57 participants completed a questionnaire assessing PTSS.

RESULTS

Significant interactions between anxiety and LPP emerged in predicting pandemic-related PTSS, where greater anxiety symptoms predicted PTSS only in individuals with greater LPP to unpleasant or with reduced LPP to pleasant stimuli.

LIMITATIONS

The prevalence of the female sex, the relatively young age of the participants, as well as the fact that they were all enrolled in a University course might not allow the generalization of the findings.

CONCLUSIONS

Taken together, the present longitudinal study provided novel evidence on EEG predictors of pandemic-related PTSS that might be useful for the prevention and treatment of PTSS. Indeed, assessing anxiety symptoms and pre-trauma LPP to emotional stimuli might be a useful target for identifying individuals that are more vulnerable to the development of PTSS during times of crisis.

Abstract thinking as a risk factor for the development of posttraumatic stress disorder symptoms in student paramedics

cognitive processing is characterized by "why?" and "what if?" questions and associated with processes such as rumination and worry. The tendency to think abstractly in response to stress has not been examined as a longitudinal risk factor for later stress reactions. The present study evaluated the extent to which an abstract thinking style could represent a risk factor for posttraumatic stress disorder (PTSD) symptoms in student paramedics over a 6-month follow-up period. Student paramedics (N = 89) recruited from universities in the United Kingdom were assessed for baseline symptoms, abstract thinking, and cognitive responses to stressful memories; a follow-up assesment was conducted 6 months later in their training. All participants were exposed to a potentially traumatic event between baseline and follow-up. Baseline symptoms and trauma history accounted for 45% of the variation in follow-up posttraumatic symptoms, with abstract thinking style explaining an additional 2.5% over and above what could be predicted from initial symptom levels. Abstract thinking was moderately related to rumination in response to stressful memories, r = .45, and correlated with follow-up symptoms of PTSD, r = .49; anxiety, r = .40; and depression, r = .27. This study builds on previous work suggesting that abstract processing mode and abstract rumination are risk factors for PTSD. Abstract thinking in response to stress represents a potentially modifiable risk factor that could be targeted by a resilience-focused intervention for individuals likely to encounter traumatic events.

Effectiveness of psychosocial interventions in mitigating adverse mental health outcomes among disaster-exposed health care workers: A systematic review

Health care workers worldwide are at an increased risk of a range of adverse mental health outcomes, including posttraumatic stress disorder (PTSD), following the unprecedented demand placed upon them during the COVID-19 pandemic. Psychosocial interventions offered to mitigate these risks should be based on the best available evidence; however, limited information regarding the comparative effectiveness of interventions is available. We undertook a systematic review of psychosocial interventions delivered to health care workers before, during, and after disasters. Eight databases were searched, including the Cochrane Central Register of Controlled Trials, PubMed/MEDLINE, EMBASE, and PsycINFO. Our primary outcomes were changes in symptoms of PTSD, anxiety, depression, and sleep. We calculated effect sizes, where unreported, and reliable change indices to appraise intervention effectiveness. The study was registered with PROSPERO (CRD42020182774). In total, 12,198 papers were screened, 14 of which were included in the present review. Interventions based on evidence-based protocols, including individual and group-based cognitive behavioral therapy (CBT) for PTSD, anxiety, and depression were found to lead to reliable changes in PTSD and anxiety symptoms. Single-session debriefing and psychological first aid workshops showed limited efficacy. There is limited evidence on psychosocial interventions for health care workers faced with disasters, with the strongest evidence base for CBT-based approaches. Future research should include controlled evaluations of interventions and aim to target identified risk factors.

Coping in the Emergency Medical Services: Associations with the personnel’s stress, self-efficacy, job satisfaction, and health

Background

Emergency Medical Services personnel (EMSP) are recurrently exposed to chronic and traumatic stressors in their occupation. Effective coping with occupational stressors plays a key role in enabling their health and overall well-being. In this study, we examined the habitual use of coping strategies in EMSP and analyzed associations of coping with the personnel’s health and well-being.

Method

A total of N = 106 German Red Cross EMSP participated in a cross-sectional survey involving standardized questionnaires to report habitual use of different coping strategies (using the Brief-COPE), their work-related stress, work-related self-efficacy, job satisfaction, as well as mental and physical stress symptoms.

Results

A confirmatory factor analysis corroborated seven coping factors which have been identified in a previous study among Italian emergency workers. Correlation analyses indicated the coping factor “self-criticism” is associated with more work-related stress, lower job satisfaction, and higher depressive, posttraumatic, and physical stress symptoms. Although commonly viewed as adaptive coping, the coping factors “support/venting”, “active coping/planning”, “humor”, “religion”, and “positive reappraisal” were not related to health and well-being in EMSP. Exploratory correlation analyses suggested that only “acceptance” was linked to better well-being and self-efficacy in EMSP.

Conclusion

Our results emphasize the need for in-depth investigation of adaptive coping in EMSP to advance occupation-specific prevention measures.

Mental health and help seeking among trauma-exposed emergency service staff: a qualitative evidence synthesis

OBJECTIVES

To identify factors and contexts that may contribute to mental health and recovery from psychological difficulties for emergency service workers (ESWs) exposed to occupational trauma, and barriers and facilitators to help-seeking behaviour among trauma-exposed ESWs.

BACKGROUND

ESWs are at greater risk of stressor-related psychopathology than the general population. Exposure to occupational stressors and trauma contribute to the observed rates of post-trauma psychopathology in this occupational group with implications for workforce sustainability. Types of organisational interventions offered to trauma-exposed ESWs are inconsistent across the UK, with uncertainty around how to engage staff.

DESIGN

Four databases (OVID MEDLINE, EMBASE, PsycINFO and SCOPUS) were systematically searched from 1 January 1980 to March 2020, with citation tracking and reference chaining. A modified Critical Appraisal Skills Programme tool and quality appraisal prompts were used to identify fatally flawed studies. Qualitative studies of trauma-exposure in front-line ESWs were included, and data were extracted using a customised extraction table. Included studies were analysed using thematic synthesis.

RESULTS

A qualitative evidence synthesis was conducted with 24 qualitative studies meeting inclusion criteria, as defined by the PerSPEcTiF framework. Fourteen descriptive themes emerged from this review, categorised into two overarching constructs: (1) factors contributing to mental health (such as the need for downtime, peer support and reassurance) and (2) factors influencing help-seeking behaviour (such as stigma, the content/form/mandatory nature of interventions, and mental health literacy issues including emotional awareness and education).

CONCLUSION

ESWs reported disconnect between the organisations' cultural positioning on trauma-related mental health, the reality of undertaking the role and the perceived applicability and usefulness of trauma interventions. Following traumatic exposure, ESWs identify benefitting from recovery time and informal support from trusted colleagues. A culture which encourages help seeking and open dialogue around mental health may reduce stigma and improve recovery from mental ill health associated with trauma exposure.

The Impact of Virtual Reality Exposure on Stress Level and Sense of Competence in Ambulance Workers

Virtual reality (VR) exposure is used in clinical psychology to treat anxiety disorders. It is also used to enhance resilience in soldiers by allowing them to confront virtual combat environments to help fortify them against the negative consequences of trauma exposure. Most VR studies have focused on military and emergency medical staff; however, thus far, none have investigated VR in ambulance workers (AWs), who are confronted with traumatic situations daily. The current study aimed to assess the impact of a single VR exposure session on self-perceived competence and stress level in a sample of AWs. Participants (N = 40) were randomly assigned to either a VR immersion (i.e., experimental group, n = 20) or an audio immersion (i.e., control group, n = 20) of a shooting attack situation. We hypothesized that compared to controls, VR participants would report decreased anxiety, as measured using visual analog scales, as well as an increased sense of competence. The results showed a significant reduction in fear in both groups, d = 0.33, and an increased sense of competence in VR participants, d = 0.35. Although our hypotheses were only partially confirmed, the observed beneficial effects of VR and the audio immersion on stress levels in AWs suggest that VR exposure could be a useful way to increase resilience in AWs.

The relationship between resilience and psychological characteristics of paramedicine students

BACKGROUND

Paramedics' continued exposure to occupational stressors can have a detrimental effect on their psychological well-being. Resilience can provide for better coping. Understanding individual differences provides explanations why some individuals thrive while others are more at risk.

AIM

To explore the effect of Personality according to the Big-Five, Ways of Thinking and Occupational Preference according to Holland's RIASEC Model, on resilience.

METHOD

Using a quantitative cross-sectional design, The Big-Five Inventory, Ways of Thinking, Brief RIASEC Marker Scales and Connor Davidson CD-RISC were administered.

RESULTS

Standard Multiple Regression showed that resilience is more likely to be seen in those who score high in Conscientiousness and low in Neuroticism. Modelling also showed that resilience is more likely to be seen in those who score high in Surgency (β = 0.364, p = .001) followed by the Freethinker (β = 0.312, p = .001), Scientific (β = 0.112, p = .027) and Controlled (β = 0.105, p = .040) ways of thinking. Although the RIASEC model was not a strong predictor of resilience, the Social (β = 0.252, p = .001) and Investigative (β = 0.153, p = .020) factors were highlighted as contributing towards a paramedic's resilience.

CONCLUSION

The paramedicine students that participated in this study report higher levels of some of the personality traits inherently protective in facilitating resilience.

Adherence to Psychological First Aid after Exposure to a Traumatic Event at Work among EMS Workers: A Qualitative Study

Managing post-traumatic stress reactions in the first few days after exposure to a potentially traumatic event in the course of one's work remains a challenge for first responder organizations such as Emergency Medical Services (EMS). Psychological First Aid (PFA) is an evidence-informed approach to reducing initial distress and promoting short- and long-term coping strategies among staff in the aftermath of exposure. PFA provided by peer helpers is considered a promising solution for first responder organizations. Unfortunately, first responders may encounter stigma and barriers to mental health care. Therefore, a deeper investigation is needed regarding adherence over time to implemented PFA intervention. The purpose of this study is to qualitatively explore factors that influence adherence to PFA intervention of recipients and peer helpers. EMS workers (n = 11), working as PFA peer helpers for one year, participated in semi-structured interviews. Data were analyzed using thematic analysis; intercoder reliability (κ = 0.91) was also used. Researchers identified four themes and 11 subthemes influencing adherence to PFA intervention: (1) individual perceptions and attitudes of peer helpers and recipients about pfa intervention; (2) perceived impacts on peer helpers and recipients; (3) organizational support to pfa intervention; and (4) congruence with the occupational culture. Study findings herein suggest that it is conceivable to act on various factors to improve adherence to PFA intervention among peer helpers and recipients within EMS organization. This could lead to enhanced understanding of the challenges involved in sustaining a peer led PFA program for first responders.

Posttraumatic stress disorder: from gene discovery to disease biology

Posttraumatic stress disorder (PTSD) is a complex mental disorder afflicting approximately 7% of the population. The diverse number of traumatic events and the wide array of symptom combinations leading to PTSD diagnosis contribute substantial heterogeneity to studies of the disorder. Genomic and complimentary-omic investigations have rapidly increased our understanding of the heritable risk for PTSD. In this review, we emphasize the contributions of genome-wide association, epigenome-wide association, transcriptomic, and neuroimaging studies to our understanding of PTSD etiology. We also discuss the shared risk between PTSD and other complex traits derived from studies of causal inference, co-expression, and brain morphological similarities. The investigations completed so far converge on stark contrasts in PTSD risk between sexes, partially attributed to sex-specific prevalence of traumatic experiences with high conditional risk of PTSD. To further understand PTSD biology, future studies should focus on detecting risk for PTSD while accounting for substantial cohort-level heterogeneity (e.g. civilian v. combat-exposed PTSD cases or PTSD risk among cases exposed to specific traumas), expanding ancestral diversity among study cohorts, and remaining cognizant of how these data influence social stigma associated with certain traumatic events among underrepresented minorities and/or high-risk populations.

The effect of concreteness training on peri-traumatic processing and intrusive memories following an analogue trauma

High levels of rumination are a risk factor for developing posttraumatic stress disorder (PTSD). Theoretical models of rumination as well as earlier empirical findings suggest that the dysfunctional effects of rumination are due to an abstract processing style, and that a more concrete style of thinking has beneficial effects on mental well-being. The present study therefore examined whether concreteness training prior to watching a trauma film prevents analogue PTSD symptoms in the form of intrusive memories. Healthy participants either received concreteness training or were allocated to a no-intervention control condition, and watched a distressing film three days later. We examined differences in intrusive memories related to the film scenes between conditions, and tested whether concreteness training reduces the link between trait rumination and analogue PTSD symptoms. Furthermore, the interacting effect of concreteness training and trait rumination on peri-traumatic processing was investigated. In line with the hypotheses, concreteness training was associated with less frequent intrusive memories and moderated the association between trait rumination and intrusive memories as well as trait rumination and dissociation during the film. These findings lend support to the hypothesis that processing style contributes to the negative impact of rumination on posttraumatic stress symptoms. In addition, they provide preliminary evidence that concreteness training may be a promising intervention for the prevention of PTSD following trauma.

Depression in post-traumatic stress disorder

Major depressive disorder (MDD) symptoms commonly occur after trauma-exposure, both alone and in combination with post-traumatic stress disorder (PTSD). This article reviews recent research on comorbidity between these disorders, including its implications for symptom severity and response to treatment. Despite considerable symptom overlap, the two disorders represent distinct constructs and depend, at least in part, on separate biological mechanisms. Both, however, are also clearly related to stress psychopathology. We recommend that more research focus specifically on the study of individual differences in symptom expression in order to identify distinct subgroups of individuals and develop targeted treatments. However, a barrier to this line of inquiry is the trend of excluding particular patients from clinical trials of new interventions based on symptom severity or comorbidity. Another obstacle is the overreliance on self-report measures in human research. We argue that developing computer-based behavioral measures in order to supplement self-report can help address this challenge. Furthermore, we propose that these measures can help tie findings from human and non-human animal research. A number of paradigms have been used to model MDD-and PTSD-like behavior in animals. These models remain valuable for understanding the biological basis of these disorders in humans and for identifying potential interventions, but they have been underused for the study of comorbidity. Although the interpretation of animal behavior remains a concern, we propose that this can also be overcome through the development of close human analogs to animal paradigms.

Increasing treatment-seeking intentions of US veterans in the Covid-19 era: A randomized controlled trial

BACKGROUND

Veterans have higher rates of anxiety, depression, and posttraumatic stress disorder (PTSD), and may be vulnerable to mental health consequences of the Covid-19 pandemic. More than half of veterans who meet mental illness criteria do not seek help. This study screened for clinical symptoms and evaluated the efficacy of a brief, online social-contact-based video intervention in increasing treatment-seeking intentions among veterans. We hypothesized that the video-based intervention would increase treatment-seeking intentions more than written vignette and control conditions.

METHODS

One hundred seventy-two veterans were randomized to either a (a) brief video-based intervention; (b) written vignette intervention, or (c) nonintervention control group. In the 3-min video, a veteran previously diagnosed with PTSD described his symptom reactivation by Covid-19, his barriers to care, and how therapy helped him to cope. Assessments were conducted at baseline, postintervention, and at 14- and 30-day follow-ups.

RESULTS

A total of 91 (53%) veterans reported high levels of clinical symptoms, especially those self-reporting Covid-19 exposure. The brief video-based intervention yielded greater increase in treatment-seeking intentions among veterans. Within the video group, women showed an increase in treatment-seeking intentions from baseline to postintervention only, whereas men showed a more sustained effect, from baseline to Day 14.

CONCLUSIONS

Surveyed veterans reported high symptoms levels. A brief video intervention increased treatment-seeking intention, likely through identification and emotional engagement with the video protagonist. This easily disseminable video-based intervention has the potential to increase likelihood of seeking care. Future research should examine longer term sustainability and changes in help-seeking behavior.

Psychosocial factors and subsequent risk of hospitalizations with peripheral artery disease: The Atherosclerosis Risk in Communities (ARIC) Study

BACKGROUND AND AIMS

Psychosocial factors are associated with increased risk of cardiovascular disease (CVD). However, associations with peripheral artery disease (PAD) remain uncharacterized. We aimed to compare associations of psychosocial factors with the risk of PAD and two other major atherosclerotic CVD: coronary heart disease (CHD) and ischemic stroke, in the Atherosclerosis Risk in Communities (ARIC) Study.

METHODS

In 11,104 participants (mean age 56.7 [SD 5.7] years) without a clinical history of PAD and CHD/stroke at baseline (1990-1992), we evaluated four psychosocial domains: depressive/fatigue symptoms by the Maastricht Questionnaire, social support by the Interpersonal Evaluation List, social networks by the Lubben Scale, and trait anger by the Spielberger Scale. PAD was defined as hospitalizations with diagnosis or related procedures. CHD included adjudicated coronary heart disease and stroke included ischemic stroke.

RESULTS

We observed 397 PAD and 1940 CHD/stroke events during a median follow-up of 23.1 years. Higher depressive/fatigue symptoms and less social support were significantly associated with incident PAD (adjusted hazard ratios for top vs. bottom quartile 1.65 [95%CI, 1.25-2.19] and 1.40 [1.05-1.87], respectively). When these factors were simultaneously modeled, only depressive/fatigue symptoms remained significant. Incident CHD/stroke was not associated with either of depressive/fatigue symptoms or social support. Social networks and trait anger were not independently associated with PAD or CHD/stroke.

CONCLUSIONS

Depressive/fatigue symptoms and social support (especially the former) were independently associated with the risk of hospitalizations with PAD but not CHD/stroke in the general population. Our results support the importance of depressive/fatigue symptoms in vascular health and suggest the need of including PAD when studying the impact of psychosocial factors on CVD.

To Be or Not to Be Flexible: Selective impairments as a means to differentiate between depression and PTSD symptoms

During the course of their lives, most individuals experience at least one potentially traumatic event. For some individuals this experience may result in them developing depression and/or post-traumatic stress disorder (PTSD) symptoms. The aim of the present study was to test the interactive effect of traumatic exposure and impaired cognitive flexibility on the tendency to develop either depression or PTSD symptoms. Eighty-two college students (M age = 25.32, SD age = 4.09) were assessed for exposure to traumatic events, depressive and PTSD symptoms. In addition, they completed a performance-based learning paradigm to evaluate the unique patterns of cognitive flexibility, defined as reduced and enhanced updating of prior knowledge in the face of new information. We predicted and found that for individuals with reduced updating, greater exposure to trauma was associated with elevated depressive symptoms. Contrary to our prediction, for individuals with enhanced updating, greater exposure was associated with elevated PTSD symptoms. While cognitive flexibility is traditionally associated with adaptive outcomes, our results illuminate the important role of a delicate updating balance to adaptively cope with aversive life events. The findings highlight the possible different roles of cognitive flexibility in the development of psychopathology and may serve as a first step toward developing tailored prevention and treatment methods.

A model of risk for perinatal posttraumatic stress symptoms

Existing research suggests that childbirth may be a significant trigger of posttraumatic stress symptoms (PTSS). The current study examined whether subjective birthing experiences and objective childbirth characteristics mediated the association between predisposing psychosocial factors measured during pregnancy (e.g., fear of childbirth, history of trauma, and social support) and PTSS during the postpartum period. Women were recruited during pregnancy from a large Midwestern hospital. Symptoms of posttraumatic stress, obsessive compulsive disorder (OCD), and depression, as well as PTSS-related risk factors, including social support, lifetime trauma exposure, fear of childbirth, subjective perceptions, and objective characteristics of childbirth, were measured during pregnancy and 4, 8, and 12 weeks postpartum. A path model revealed that subjective perceptions of childbirth mediated the association between fear of childbirth and PTSS at 4 weeks postpartum. Objective childbirth characteristics mediated the association between fear of childbirth and PTSS at 8 weeks postpartum, and there was a direct association between fear of childbirth and PTSS. Subjective perceptions of childbirth also mediated the effect of fear of childbirth on PTSS at 4 weeks postpartum when controlling for OCD symptoms. Further, the direct effect of fear of childbirth on PTSS at 8 weeks postpartum remained significant when controlling for OCD symptoms. The current study emphasizes the importance of fear of childbirth and subjective and objective birthing experiences in predicting postpartum psychopathology. Future research should examine these models in diverse and at-risk samples. Valid assessments and effective interventions for perinatal PTSS should be explored.

Dynamic psychosocial risk and protective factors associated with mental health in Emergency Medical Service (EMS) personnel

BACKGROUND

EMS personnel have a heightened risk of developing posttraumatic stress disorder (PTSD) and major depression relative to other occupational populations necessitating a greater understanding of the risk and protective factors that operate each day in relation to this risk. This study examined dynamic psychosocial factors and their relationship with daily mental health symptoms among EMS workers. The psychosocial factors examined consisted of occupational stressors, sleep disturbance, social conflict, meaning made from the day's challenges, recovery activities, social support, and perceived prosocial impact.

METHOD

Seventy-nine EMS workers recruited from an emergency medical service provider in Central New York completed a daily assessment for 8 days asking questions about occupational stressors encountered, sleep efficiency, social conflicts, meaning made from the day's challenges, recovery activities engaged in, social support received, and perceived prosocial impact.

RESULTS

Daily occupational stressors were associated with elevated daily PTSD symptom severity (b = 0.13, SE = 0.06, p = .023). Social conflicts were associated with greater depression symptom severity (b = 0.75, SE = 0.14, p < .001); the meaning made from day's stressors (b = -0.17, SE = 0.05, p = .002) and the recovery activities engaged in (b = -0.30, SE = 0.07, p < .001) were associated with lower daily depression symptom severity.

LIMITATIONS

A relatively modest sample size and small sampling window may constrain the generalizations made from this study.

CONCLUSIONS

Occupational stressors and social conflicts are key risk factors related to the daily expression of PTSD and depression symptom severity in EMS workers. The meaning made from the day's challenges and the recovery activities engaged in may protect against depression. These results reveal several dynamic psychosocial factors that aid in understanding features of the work day that contribute to the mental health burden observed among EMS personnel.

Mental health, well-being and support interventions for UK ambulance services staff: an evidence map, 2000 to 2020

Background:

Prior to COVID-19 there had been a renewed policy focus in the National Health Service on the health and well-being of the healthcare workforce, with the ambulance sector identified as a priority area. This focus is more important than ever as the sector deals with the acute and longer-term consequences of a pandemic.

Aim:

To systematically identify, summarise and map the evidence regarding mental health, well-being and support interventions for United Kingdom ambulance services staff and to identify evidence gaps.

Method:

Evidence mapping methodology of published and grey original research published in English from 1 January 2000 to 23 May 2020 describing the health risk, mental health and/or well-being of UK ambulance services staff including retired staff, volunteers and students. MEDLINE, EMBASE, PsychINFO, CINAHL and AMED databases, plus EThOS, Zetoc, OpenGrey and Google, were searched, alongside hand-searching of grey literature and bibliographies. Information was extracted on study aims, sample, design and methodology, funding source, country and key findings. Included studies were categorised into seven a priori theme areas.

Results:

Of 1862 identified articles, 45 peer-reviewed studies are included as well as 24 grey literature documents. Peer-reviewed research was largely observational and focused on prevalence studies, post-traumatic stress disorder or organisational and individual social factors related to health and well-being. Most grey literature reported the development and testing of interventions. Across all study types, underpinning theory was often not cited.

Conclusion:

To date, intervention research has largely been funded by charities and published in the grey literature. Few studies were identified on self-harm, bullying, sleep and fatigue or alcohol and substance use. Theoretically informed intervention development and testing, including adaptation of innovations from other countries and 24-hour workforces, is needed. This evidence map provides important context for planning of staff well-being provision and research as the sector responds to and recovers from the pandemic.

Prospective risk and protective factors for psychopathology and wellbeing in civilian emergency services personnel: a systematic review

Emergency services personnel have an elevated risk of developing mental health conditions. Most research in this area is cross-sectional, which precludes inferences about temporal and potentially causal relationships between risk and protective factors and mental health outcomes. The current study systematically reviewed prospective studies of risk and protective factors for mental health outcomes in civilian emergency services personnel (firefighters, paramedics, police) assessed at pre-operational and operational stages. Out of 66 eligible prospective studies identified, several core groups of risk and protective factors emerged: (1) cognitive abilities; (2) coping tendencies; (3) personality factors; (4) peritraumatic reactions and post-trauma symptoms; (5) workplace factors; (6) interpersonal factors; (7) events away from work. Although there was insufficient evidence for many associations, social support was consistently found to protect against the development of mental health conditions, and peritraumatic dissociation, prior mental health issues, and prior trauma exposure were risk factors for future mental health conditions. Among operational studies, neuroticism was significantly associated with future PTSD symptoms, burnout, and general poor mental health, and avoidance and intrusion symptoms of PTSD were associated with future PTSD and depression symptoms. The current review results provide important targets for future research and interventions designed to improve the mental health of emergency services personnel.

Addressing the physician burnout epidemic with resilience curricula in medical education: a systematic review

BACKGROUND

A variety of stressors throughout medical education have contributed to a burnout epidemic at both the undergraduate medical education (UGME) and postgraduate medical education (PGME) levels. In response, UGME and PGME programs have recently begun to explore resilience-based interventions. As these interventions are in their infancy, little is known about their efficacy in promoting trainee resilience. This systematic review aims to synthesize the available research evidence on the efficacy of resilience curricula in UGME and PGME.

METHODS

We performed a comprehensive search of the literature using MEDLINE, EMBASE, PsycINFO, Educational Resources Information Centre (ERIC), and Education Source from their inception to June 2020. Studies reporting the effect of resilience curricula in UGME and PGME settings were included. A qualitative analysis of the available studies was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Risk of bias was assessed using the ROBINS-I Tool.

RESULTS

Twenty-one studies met the inclusion criteria. Thirteen were single-arm studies, 6 quasi-experiments, and 2 RCTs. Thirty-eight percent (8/21; n = 598) were implemented in UGME, while 62 % (13/21, n = 778) were in PGME. There was significant heterogeneity in the duration, delivery, and curricular topics and only two studies implemented the same training model. Similarly, there was considerable variation in curricula outcome measures, with the majority reporting modest improvement in resilience, while three studies reported worsening of resilience upon completion of training. Overall assessment of risk of bias was moderate and only few curricula were previously validated by other research groups.

CONCLUSIONS

Findings suggest that resilience curricula may be of benefit to medical trainees. Resilience training is an emerging area of medical education that merits further investigation. Additional research is needed to construct optimal methods to foster resilience in medical education.

Early posttraumatic stress symptoms and levels of distress in trauma patients treated in the resuscitation room: an exploratory study

Background

The aim of the present study was to investigate the incidence of psychological distress and posttraumatic stress symptoms in trauma patients who have been recruited from the resuscitation room. Further, we wanted to explore risk factors for posttraumatic stress symptoms, taking different accident types into account.

Methods

Our sample consisted of 45 patients who have been treated in the resuscitation room and were interviewed within the first ten days after treatment. Type of accident, third party fault, previous mental health problems and pretraumatic stress were examined. Patients were interviewed with respect to their currently felt distress regarding the accident. Posttraumatic stress symptoms were measured with the German version of the Impact of Event Scale. Injury severity was assessed by means of the Injury Severity Score.

Results

Our exploratory and cross-sectional project reveals that more severe injuries were associated with higher distress. However, posttraumatic stress symptoms were predicted by high distress and being involved in a car accident, but not by injury severity.

Conclusions

We identified two potential risk factors for the development of posttraumatic stress in trauma patients recruited from the resuscitation room: Being involved in a car accident and high distress.

Trial registration

The project has been registered at the Study Center of Mental Disorders (SPE) at the University Medical Center Mainz (No: 92072014).

A prospective study of pre-employment psychological testing amongst police recruits

BACKGROUND

Pre-employment psychological screening to detect psychological vulnerability is common amongst emergency service organizations worldwide, yet the evidence for its ability to predict poor mental health outcomes is limited with published studies looking at post-recruitment research data rather than data collected by the organizations themselves.

AIMS

The present study sought to investigate the ability of pre-employment screening to predict later psychological injury-related absenteeism amongst police officers.

METHODS

A nested case-control study using prospective data was conducted. One hundred and fifty police officers with a liability-accepted psychological injury were matched to a control group of 150 psychologically healthy officers. Conditional logistic regression was used to examine associations between Minnesota Multiphasic Personality Inventory-2 (MMPI-2) scales measuring factors research has shown to predict psychological injury (Neuroticism, Psychoticism, Introversion, Disconstraint and Aggressiveness) and psychopathology (Depression, Anxiety and post-traumatic stress disorder [PTSD]) with subsequent psychological injury.

RESULTS

Contrary to expectations, we were unable to demonstrate any association between validated pre-employment measures of personality and psychopathology with mental health outcomes amongst newly recruited police officers over a 7-year follow-up.

CONCLUSIONS

Other measures may be better able to predict future mental health problems in police recruits.
