Summary: This study aims to investigate critical incident trauma (CIT), social support, resilience, and post-traumatic stress disorder (PTSD) in Korean police officers, and to determine factors related to PTSD for developing effective interventions. The results showed that perceived health status, CIT, social support, and resilience were significantly related to PTSD. The stakeholders also provided insights on the difficulties and coping strategies after CIT, the current status of counseling programs, and suggestions for PTSD interventions.

Summary: This study aimed to investigate the profiles of moral injury (MI) and post-traumatic stress disorder (PTSD) symptoms among trauma-exposed, treatment-seeking police officers and military veterans, and explore the differences between these profiles. The results showed that a substantial proportion of participants met the diagnostic criteria for MI, and the MI-PTSD class had the highest severity of comorbid psychopathology symptoms. This suggests the need for routine screening and interventions for MI in these populations.

Summary: This study aimed to identify the associations of military-related traumatic brain injury (TBI) with suicide and new-onset mental health conditions. The findings showed that soldiers with a history of TBI had higher rates of new-onset mental health conditions and were at greater risk of suicide. These results highlight the need for increased efforts to address the cumulative risk associated with multiple military-related exposures.

Summary: This study examined the presence of chronic traumatic encephalopathy (CTE) in the brains of military personnel. The results showed that CTE was infrequently found, but it was more prevalent in individuals with exposure to contact sports and traumatic brain injury (TBI) in civilian life. However, the small number of cases and wide confidence intervals limit the ability to draw causal conclusions.

Summary: Due to a lack of empirical study, it is still unclear whether a service dog truly mitigates the burden of post-traumatic stress disorder (PTSD) symptoms. However, a study found that veterans and first aid responders with PTSD who had a service dog showed fewer PTSD related symptoms, better sleep quality, and better wellbeing experience compared to those with a companion dog.

Summary: Military veterans with PTSD have distinct experiences of loneliness and social isolation. This systematic review aims to examine the impact of interventions addressing social connection, social isolation, and loneliness on this community. The review found that interventions focusing on social reintegration, peer support, empowerment, and building trust may help mitigate experiential loneliness and social isolation for veterans with PTSD.

Summary: This is the first population-based study to simultaneously consider PTSD diagnosis and symptom severity, finding that any level of PTSD symptoms above the minimum threshold for symptomatic remission is associated with an increased suicide mortality rate. Improving PTSD symptoms can reduce the risk of suicide mortality, but achieving symptomatic remission is necessary to attain this benefit.

Summary: Male personnel are more likely to report moderate/large PTG if they perceive serious danger, are reservists, have good/excellent general health, experienced more combat, consume less alcohol, have better mental health, lower rank, or younger. Female personnel are more likely to report moderate/large PTG if they are single, have left military service, have better mental health, are reservists, experienced more combat, or are younger. PTSD has a curvilinear relationship with PTG.

Summary: This study conducted a systematic review of the scientific literature to analyze the risk and protective factors related to the development of PTSD in firefighters. The findings suggest that operational stress, job duration, burnout, expressive suppression, and rumination could be risk factors of PTSD, while belongingness and dispositional mindfulness could be protective factors. The review highlights the scarcity of available literature on the subject and emphasizes the importance of further research to prevent PTSD in firefighters.

Summary: Post-traumatic stress disorder (PTSD) is closely related to neuroinflammation, which plays a key role in the pathogenesis of PTSD. Activation of immune cells and changes in inflammatory markers in the brain are involved in neuroinflammation. Understanding the mechanisms of neuroinflammation in PTSD is crucial for studying the disorder.

Summary: The study found that 8-week PTSD prevalence after traffic accidents was relatively high (42.0%), and was positively associated with participant sex (female), low socioeconomic status (education and income), and self-report indicators of accident severity. Most of these associations were entirely mediated by peritraumatic symptoms and, to a lesser degree, acute stress disorder (ASD), suggesting that the first 2 weeks after trauma may be a critical period for intervening to prevent and reduce PTSD risk.

Summary: Based on the Conservation of Resources theory, this research examines the relationship between work-family relationships and employees' well-being in teleworking situations, and investigates the role of Family-Supportive Supervisor Behaviors (FSSB) as a vital resource in helping employees balance work and life domains while teleworking. The findings indicate that FSSB is significantly associated with positive outcomes for work-family relationship and well-being, with the intensity of telework acting as a conditional factor.

Summary: This study aims to analyze the impact of transformational leadership on firefighters' well-being and understand how the frequency of intervention in rural fires moderates this relationship. The responses of 90 Portuguese professional firefighters were analyzed in two waves, and the frequency of intervention in rural fires was recorded daily. The results show a positive direct effect of transformational leadership on flourishing, with the frequency of intervention in rural fires amplifying the effect of individual consideration on well-being. These findings contribute to the literature on well-being in high-risk professions and have practical implications for future studies.

Summary: A growing number of studies have examined the relationship between personal resources, such as emotional intelligence, and occupational well-being, particularly work engagement. However, few studies have investigated the role of health-related factors in mediating or moderating this relationship. This study aimed to explore the mediating and moderating role of perceived stress in the association between emotional intelligence and work engagement. The results revealed that perceived stress partially mediated the link between emotional intelligence and work engagement, and the positive relationship between emotional intelligence and work engagement was stronger among individuals experiencing high levels of perceived stress. These findings suggest that interventions targeting stress management and emotional intelligence development can enhance work engagement in emotionally demanding professions like teaching.

Summary: This study aims to understand the effects of two leadership styles (empowering vs. directive) on subordinates' well-being in an emergency situation (i.e., rural fire). A simulation study was conducted with two experimental conditions (empowering vs. directive leadership), and the subordinates' stress levels were measured before and after the simulated episode. Contrary to expectations, empowering leadership had no significant effect on subordinates' stress levels, while directive leadership contributed to reducing them. As expected, this effect was stronger for the subordinates with higher levels of stress prior to the simulated episode.

Summary: The purpose of this study is to explore the relationship between job insecurity and employee performance, as well as the mechanisms and contextual factors that affect this relationship. Through the analysis of 81 empirical studies, it was found that the cognitive dimension is dominant in job insecurity research, and in-role performance and organizational citizenship behavior are the most frequently studied dimensions. Furthermore, various mechanisms and contextual factors at the individual and job-level have been found to play a role in this relationship.

Summary: This study developed a model explaining personal attitudes toward religious groups and the role of parental religious heterogamy and homogamy. The sample included 32,595 participants from 26 countries and found that participants whose parents were religiously homogamous showed higher well-being, better health perception, and higher religiosity. Religious variables were directly related to parents' religious heterogamy/homogamy and indirectly related to well-being and personal attitude toward religious groups. The study also found that participants with religiously heterogamous parents had a more negative attitude toward Christians, Muslims, Hindus, and Jews, while participants with religiously homogamous parents had a more negative attitude toward atheists or nonbelievers.
