Background: Public Safety Personnel (e.g., firefighters, paramedics, and police officers) are routinely exposed to human suffering and need to make quick, morally challenging decisions. Such decisions can affect their psychological wellbeing. Participating in or observing an event or situation that conflicts with personal values can potentially lead to the development of moral injury. Common stressors associated with moral injury include betrayal, inability to prevent death or harm, and ethical dilemmas. Potentially psychologically traumatic event exposures and post-traumatic stress disorder can be comorbid with moral injury; however, moral injury extends beyond fear to include spiritual, cognitive, emotional or existential struggles, which can produce feelings of severe shame, guilt, and anger.Objective: This scoping review was designed to identify the extant empirical research regarding the construct of moral injury, its associated constructs, and how it relates to moral distress in firefighters, paramedics, and police officers.Methods: A systematic literature search of peer-reviewed research was conducted using databases MEDLINE, EMBASE, APA PsychInfo, CINHAL PLUS, Web of Science, SCOPUS, and Google Scholar. Included studies were selected based on the inclusion criteria before being manually extracted and independently screened by two reviewers.Results: The initial database search returned 777 articles, 506 of which remained after removal of duplicates. Following review of titles, abstracts, and full texts, 32 studies were included in the current review. Participants in the articles were primarily police officers, with fewer articles focusing on paramedics and firefighters. There were two studies that included mixed populations (i.e., one study with police officers, firefighters, and other emergency service workers; one study with paramedic and firefighter incident commanders). Most studies were qualitative and focused on four topics: values, ethical decision-making, organizational betrayal, and spirituality.Conclusion: Public safety organizations appear to recognize the experience of moral distress or moral injury among public safety personnel that results from disconnects between personal core values, formal and informal organizational values, vocational duties, and expectations. Further research is needed to better understand moral distress or moral injury specific to public safety personnel and inform training and treatment in support of public safety personnel mental health.

A police officer’s career is hazardous and physically demanding. In order to perform occupational tasks effectively and without injury, officers require adequate physical abilities. The aim of this study was to investigate the relationship between scores on several fitness tests and musculoskeletal injury in a group of municipal police officers. This retrospective study used existing data to examine the relationship between risk of injury and fitness test performance. Injured and uninjured police officers scored significantly differently on several fitness measures. A multivariate regression indicated that a combination of age, sex, number of pull ups completed and maximal oxygen consumption (VO2max) best explained injury risk. Additionally, the findings indicated an interaction between sex and VO2max, and so the effect of VO2max on injury risk cannot be understood without accounting for sex.

The work of public safety personnel (PSP) is inherently moral; however, the ability of PSP to do what is good and right can be impeded and frustrated, leading to moral suffering. Left unresolved, moral suffering may develop into moral injury (MI) and potential psychological harm. The current study was designed to examine if MI is relevant to frontline public safety communicators, firefighters, and paramedics. Semi-structured interviews (n = 3) and focus groups (n = 3) were conducted with 19 participants (public safety communicators (n = 2); paramedics (n = 7); and firefighters (n = 10)). Interviews and focus groups were audio-recorded, transcribed, coded, and constantly compared in accordance with the grounded theory method. A conceptual theory of “frustrating moral expectations” emerged, with participants identifying three interrelated properties as being potentially morally injurious: chronic societal problems, impaired systems, and organizational quagmires. Participants navigated their moral frustrations through both integrative and disintegrative pathways, resulting in either needing to escape their moral suffering or transforming ontologically. The current study results support MI as a relevant concept for frontline PSP. Given the seriousness of PSP leaving their profession or committing suicide to escape moral suffering, the importance of the impact of MI on PSP and public safety organizations cannot be ignored or underestimated. Understanding the similarities and differences of morally injurious exposures of frontline PSP may be critical for determining mental health and resilience strategies that effectively protect PSP.

Background: Military members are at elevated risk of operational stress injuries, including posttraumatic stress disorder (PTSD) and moral injury. Although psychotherapy can reduce symptoms, some military members may experience treatment-resistant PTSD. Multimodular motion-assisted memory desensitization and reconsolidation (3MDR) has been introduced as a virtual reality (VR) intervention for military members with PTSD related to military service. The 3MDR intervention incorporates exposure therapy, psychotherapy, eye movement desensitization and reconsolidation, VR, supportive counselling, and treadmill walking. Objective: The objective of this study is to investigate whether 3MDR reduces PTSD symptoms among military members with combat-related treatment-resistant PTSD (TR-PTSD); examine the technology acceptance and usability of the Computer Assisted Rehabilitation ENvironment (CAREN) and 3MDR interventions by Canadian Armed Forces service members (CAF-SMs), veterans, 3MDR clinicians, and operators; and evaluate the impact on clinicians and operators of delivering 3MDR. Methods: This is a mixed-methods waitlist controlled crossover design randomized controlled trial. Participants include both CAF-SMs and veterans (N=40) aged 18-60 years with combat-related TR-PTSD (unsuccessful experience of at least 2 evidence-based trauma treatments). Participants will also include clinicians and operators (N=12) who have been trained in 3MDR and subsequently utilized this intervention with patients. CAF-SMs and veterans will receive 6 weekly 90-minute 3MDR sessions. Quantitative and qualitative data will be collected at baseline and at 1, 3, and 6 months postintervention. Quantitative data collection will include multiomic biomarkers (ie, blood and salivary proteomic and genomic profiles of neuroendocrine, immune-inflammatory mediators, and microRNA), eye tracking, electroencephalography, and physiological data. Data from outcome measures will capture self-reported symptoms of PTSD, moral injury, resilience, and technology acceptance and usability. Qualitative data will be collected from audiovisual recordings of 3MDR sessions and semistructured interviews. Data analysis will include univariate and multivariate approaches, and thematic analysis of treatment sessions and interviews. Machine learning analysis will be included to develop models for the prediction of diagnosis, symptom severity, and treatment outcomes. Results: This study commenced in April 2019 and is planned to conclude in April 2021. Study results will guide the further evolution and utilization of 3MDR for military members with TR-PTSD and will have utility in treating other trauma-affected populations. Conclusions: The goal of this study is to utilize qualitative and quantitative primary and secondary outcomes to provide evidence for the effectiveness and feasibility of 3MDR for treating CAF-SMs and veterans with combat-related TR-PTSD. The results will inform a full-scale clinical trial and stimulate development and adaptation of the protocol to mobile VR apps in supervised clinical settings. This study will add to knowledge of the clinical effectiveness of 3MDR, and provide the first comprehensive analysis of biomarkers, technology acceptance and usability, moral injury, resilience, and the experience of clinicians and operators delivering 3MDR.

Background—Public safety personnel (PSP) are at heightened risk of developing mental health challenges due to exposures to diverse stressors including potentially psychologically traumatic experiences. An increased focus on protecting PSP mental health has prompted demand for interventions designed to enhance resilience. While hundreds of available interventions are aimed to improve resilience and protect PSPs’ mental health, research evidence regarding intervention effectiveness remains sparse. Methods—Focus groups with PSP elicited a discussion of psychoeducational program content, preferred modes of program delivery, when such training should occur, and to whom it ought to be targeted. Results—The results of thematic analyses suggest that PSP participants feel that contemporary approaches to improving mental health and resilience are lacking. While welcomed, the provision of sporadic one-off mental health and resilience programs by organizations was seen as insufficient, and the available organizational mental health supports were perceived as being questionable. The available programs also left participants feeling insufficiently prepared to deal with personal mental health problems and in discussing mental health concerns with co-workers. Conclusions—Participants reported needing more engaging methods for delivering information, career-long mental health knowledge acquisition, and a systems approach to improve the workplace culture, particularly regarding mental health.
