BACKGROUND: Occupational trauma is heightened among police officers due to their exposure to physical, biological, chemical, and psychological hazards. Sustained occupational trauma results in mental illness among members of the police, which is a public health issue of concern. This study aimed to report a scoping review of the literature on strategies employed by police officers for coping with occupational trauma around the globe.
METHODS: A search string, formulated from the review question of what is known about the strategies of police officers for coping with occupational trauma, was used to search for articles from databases. A total of 588 hits were screened against inclusion criteria, resulting in 36 full-text studies between 1983 and 2022 being included in this review. Data were extracted using a standardised data extraction tool. The multi-step process was used to analyse the extracted data, integrating quantitative and qualitative approaches.
RESULTS: From this review, \'adaptive coping mechanisms\', involving confrontation; \'maladaptive coping mechanisms\', such as self-isolation, distancing and substance use; \'resilience\', relating to mental preparation, and \'seeking support systems\' from family, colleagues and professionals reflected the strategies used by police officers to cope with occupational trauma. Social stigma related to mental health disorders impacts the strategies used by police officers to cope with occupational trauma.
CONCLUSIONS: the police management and healthcare practitioners must collaborate towards providing constructive environments that support and strengthen police officers\' strategies for coping with occupational trauma.

Intimate partner violence (IPV) impacts more than 40% of people in the U.S. Since the 1980s, the U.S. has maintained a police-centric response to IPV, which relies on arrest-via policies like mandatory arrest laws-as its primary intervention. There is mixed evidence on whether IPV policing decreases subsequent IPV at the individual level, but less is known about IPV policing\'s broader collateral consequences. This systematic scoping review is the first to synthesize existing evidence for the generalized consequences of IPV policing in the U.S. We searched Web of Science, ProQuest, and EBSCO Host, and identified 36 relevant articles. Survivor criminalization was the most studied generalized consequence of IPV policing and existing studies have documented positive associations between mandatory arrest laws and risk of survivor arrest. We also found numerous methodologically rigorous studies on the effects of mandatory arrest laws on population-level IPV victimization. The review also identifies gaps in the evidence base: there is a need for research on additional potential consequences of IPV policing such as police violence against survivors, involvement of child protective services, and psychosocial and physical health outcomes of survivors.

BACKGROUND: Literature on psychiatric emergency services (PES) presentations during the COVID-19 pandemic showed heterogeneous results regarding patients brought in by police (BIBP). This is the first study primarily focusing on patients BIBP in a PES during the COVID-19-period.
METHODS: Case documentation records during the first and second wave of the COVID-19 pandemic in a PES in Berlin, Germany were analyzed using descriptive data analysis and binomial logistic regression analysis to detect factors that predict presentations BIBP.
RESULTS: 5440 PES presentations: 20.4% BIBP during the first wave vs. 16.3% during its control period; second wave: 17.6% BIBP vs. 14.9% during its control period. In both waves, absolute increases in presentations BIBP were seen compared to control (p = .029, p = .028, respectively). COVID-19-period was a predictor for presentations BIBP during the first and the second wave. The following factors also predicted presentations BIBP: younger age, male gender, aggressive behavior, suicide attempt prior to presentation and diagnosis of psychotic or substance use disorders; depressive disorders were negatively associated.
CONCLUSIONS: During the two first waves of the COVID-19 pandemic, there was an increase in presentations BIBP in a PES in Berlin. Regression analysis shows that the pandemic itself was a predictor of presentations BIBP. The underlying factors of this association need to be further elucidated in future research. Additionally, general factors predicting PES presentations BIBP are reported that replenish the present literature.

The present study conducted a comprehensive meta-analysis to systematically review the relationship between occupational burnout and work pressure among Chinese police officers. Additionally, the study explored the mediating role of coping styles using a meta-analytic structural equation model. The investigation involved a thorough search of CNKI, PubMed, PsychInfo, Web of Science, and Google Scholar databases, resulting in the identification of a total of 39 studies with 124 effect sizes and 14,089 police officers. The findings revealed a positive correlation between work pressure and occupational burnout among Chinese police officers (r = 0.410, 95% CI = [0.347, 0.469]). Furthermore, negative coping styles mediate the relationship between work pressure and occupational burnout. Importantly, these conclusions held true across various work regions for police officers. These results provide insights into the relationship magnitude between work pressure and occupational burnout in Chinese police work and shed light on the underlying mechanisms. Based on these findings, it is recommended that interventions focusing on reducing work pressure and fostering positive coping styles be implemented to mitigate occupational burnout among police officers.

The interviewing of victims, witnesses and suspects is important in helping resolve criminal investigations. In Japan, developments have recently occurred in the training of the police and their public prosecutors in these key tasks. Whilst literature exists on autism in Japan, studies examining police/public prosecutor interviews with autistic adults conducted in that country (and indeed, any other) remain scant. As elsewhere in the world, identification of those who manifest characteristics prevalent on the autism spectrum disorder (ASD) scale, has been found to be problematical to criminal justice professionals. To help address this deficit in understanding, we provide an overview of the literature concerning contemporary understanding of the challenges facing autistic adults as they attempt to reveal their verbal accounts, as well as suggested techniques when interviewing adults on the ASD scale during criminal investigations, offering lessons learned from research conducted around the world that provide potentially promising solutions for Japan.

Police negotiators respond to crisis and high-risk situations including mental health crises, but little is known about the nature, frequency and characteristics of these events. This systematic review examined literature about mental disorder and suicidality prevalence in negotiation events from peer-reviewed articles published within the last 20 years. Of 1455 articles identified, 11 met study inclusion criteria. Most contributed only indirect evidence using data on fatal police encounters, case reviews and analysis of communication techniques. Reliable prevalence estimates were not found, though findings suggest suicidality was a precipitating factor in more than half of events and was present during most events. Mental disorder (primarily substance use, mood and psychotic disorders) was also identified as a significant factor prior to and during events. Few articles described frequency or characteristics of these critical events. Further research is needed to inform frontline responses, resourcing and support pathways for police providing this crucial service.

This scoping review aimed to identify and summarise evidence on the comfort and functional performance of police officer personal protective equipment (PPE). The Arksey and O\'Malley (2005) five-stage framework for scoping reviews was followed. PubMed, CINAHL, Scopus, and Web of Science were searched, and 35 articles were included in the review. The findings show that increased police PPE mass increases heart rate, metabolic energy expenditure, and perceived exertion in response to exercise. Unisex armour designs cause increased discomfort for females with larger bra sizes. PPE reduces joint-specific range of motion, with the design and location impairing movement more than mass. Jumping and sprinting performance is decreased with heavy PPE but unaffected by lighter protection, while agility is compromised with most forms of protection. Future research is needed on the fit and function of PPE for specialist police units, such as mounted police, along with further investigations on how fit can affect functional performance.
This paper identifies and reviews existing evidence on the comfort and functional performance of police officer personal protective equipment (PPE). This is significant because it summarises and categorises key concepts that underpin research in this area, whilst highlighting gaps in the current knowledge and areas for future research.

Motor vehicle crash data linkage has emerged as a vital tool to better understand the injury outcomes and the factors contributing to crashes. This systematic review and meta-analysis aims to explore the existing knowledge on data linkage between motor vehicle crashes and hospital-based datasets, summarize and highlight the findings of previous studies, and identify gaps in research. A comprehensive and systematic search of the literature yielded 54 studies for a qualitative analysis, and 35 of which were also considered for a quantitative meta-analysis. Findings highlight a range of viable methodologies for linking datasets, including manual, deterministic, probabilistic, and integrative methods. Designing a linkage method that integrates different algorithms and techniques is more likely to result in higher match rate and fewer errors. Examining the results of the meta-analysis reveals that a wide range of linkage rates were reported. There are several factors beyond the approach that affect the linkage rate including the size and coverage of both datasets and the linkage variables. Gender, age, crash type, and roadway geometry at the crash site were likely to be associated with a record\'s presence in a linked dataset. Linkage rate alone is not the only important metric and when linkage rate is used as a metric in research, both police and hospital rates should be reported. This study also highlights the importance of examining and accounting for population and bias introduced by linking two datasets.

This systematic review examines studies of traffic injury that involved linkage of police crash data and hospital data and were published from 1994 to 2023 worldwide in English. Inclusion and exclusion criteria were the basis for selecting papers from PubMed, Web of Science, and Scopus, and for identifying additional relevant papers using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and supplementary snowballing (n = 60). The selected papers were reviewed in terms of research objectives, data items and sample size included, temporal and spatial coverage, linkage methods and software tools, as well as linkage rates and most significant findings. Many studies found that the number of clinically significant road injury cases was much higher according to hospital data than crash data. Under-estimation of cases in crash data differs by road user type, pedestrian cases commonly being highly under-counted. A limited number of the papers were from low- and middle-income countries. The papers reviewed lack consistency in what was reported and how, which limited comparability.

Violence against police is a reality for many officers. Despite growing concerns over the rise in violence against police and the serious individual and societal repercussions associated with it, a comprehensive overview of the psychological and physical consequences of verbal and physical violence against police remains elusive. By performing a scoping review (n = 21) of studies and reports identified via database searches (Web of Science and Google Scholar), reference mining, and purposive sampling, and published between 2010 and 2023, this article is the first of its kind to map psychological and physical consequences of violence against police, as well as the risk and protective factors that respectively increase and decrease adverse consequences. Results indicate that officers experience primary victimization by a range of different adverse consequences, but also deal with secondary victimization. The literature has come to a standstill due to lack of (recent) studies and a lack of diversity on how consequences of violence against police are studied. We argue that this lack of academic attention might be influenced by predominant societal perspectives and officers\' perceived victim status, and discuss the implications for police, policymakers, and research.
