Background and Objectives: Emergency physicians practice in high-pressure environments and face occupational stressors that may affect their mental health. This study was designed to evaluate the prevalence of depression among emergency physicians in South Korea and examined environmental, sociolegal, and individual factors associated with depressive symptoms in the post-pandemic period. Materials and Methods: This nationwide cross-sectional study analyzed data from the 2025 Korean Emergency Physician Survey. Screening positive for depressive symptoms was defined as a Patient Health Questionnaire-9 (PHQ-9) score ≥ 10, indicating moderate-to-severe depressive symptom severity. Measures included the PHQ-9, the Korean Epworth Sleepiness Scale (KESS), and the Adult APGAR, a brief self-administered instrument assessing overall wellness. Multivariable logistic regression was performed to identify factors associated with depression after adjusting for demographic, clinical, and work-related variables. Results: Of the 1050 physicians who responded (response rate: 37.5%), 743 emergency physicians completed the PHQ-9 section (completion rate: 70.8%; mean age, 43.2 ± 7.78 years; 86.5% male), and 111 (14.9%) screened positive for depressive symptoms. Objective workload indicators, including total work hours and number of night shifts, did not differ between physicians with and without depression. However, emergency physicians screening positive for depression reported higher perceived burdens related to staffing shortages and patient-related stressors. Protective factors included being married (adjusted odds ratio [AOR], 0.22; 95% confidence interval [CI], 0.08–0.58), longer sleep duration (AOR, 0.65; 95% CI, 0.50–0.86), better sleep quality (AOR, 0.45; 95% CI, 0.27–0.74), fixed mealtimes (AOR, 0.60; 95% CI, 0.39–0.93), and higher Adult APGAR scores (AOR, 0.72; 95% CI, 0.60–0.86). Factors associated with increased odds of depression included a history of cancer (AOR, 14.63, 95% CI, 2.53–84.61), current alcohol consumption (AOR, 2.54, 95% CI, 1.14–5.68), daytime sleepiness (AOR, 1.17; 95% CI, 1.04–1.31), and more frequent verbal abuse during the previous 12 months (AOR, 1.25; 95% CI, 1.08–1.44). Conclusions: Depression was prevalent and was associated with perceived work burden, sleep health, lifestyle regularity, and psychosocial factors. Interventions should address sleep quality, workplace safety, and social support. Full article

Background: Military police officers are exposed to occupational stressors associated with mental health, coping strategies, and work engagement. This study examined mental health indicators and their associations with coping strategies and work engagement among military police officers in the pre-pandemic period. Methods: A quantitative, cross-sectional, descriptive, and correlational study was conducted in 2018 with 773 Brazilian military police officers from São Paulo (n = 506) and Paraná (n = 267). Participants completed the Work Stress Scale (WSS), Maslach Burnout Inventory (MBI-HSS), Utrecht Work Engagement Scale (UWES), and the Scale of Problem Coping Modes (EMEP). Results: The prevalence of occupational stress was 30.2%, with high proportions of Emotional Exhaustion and Depersonalization. Burnout was interpreted dimensionally (MBI-HSS subscales), with 17.6% (n = 134) joint prevalence of the high Emotional Exhaustion + high Depersonalization + low Personal Accomplishment profile, alongside frequent mixed profiles (e.g., 38.3% with high Depersonalization + low Personal Accomplishment). In the multivariable model, the 6 h shift was associated with higher odds of stress (OR = 7.76; 95% CI: 1.02–58.79), while the absence of self-reported health/quality-of-life issues was associated with lower odds (OR = 0.60; 95% CI: 0.39–0.94), along with Emotional Exhaustion (OR = 1.15; 95% CI: 1.10–1.20) and Depersonalization (OR = 1.12; 95% CI: 1.04–1.20). In sensitivity analysis, work shift was not associated with stress (aOR = 1.20; 95% CI: 0.66–2.21). Stress and burnout dimensions were negatively correlated with work engagement (r = −0.52), problem-focused coping, and social support and positively correlated with emotion-focused coping. São Paulo officers reported higher engagement and greater use of problem-focused coping and social support, whereas those in Paraná reported greater reliance on emotion-focused coping. Conclusions: Stress and burnout dimensions may coexist with high engagement, supporting the need for integrated institutional strategies that address organizational stressors (e.g., workload schedules) and strengthen potentially protective coping repertoires, while accounting for contextual differences between units. The high prevalence of burnout profiles underscores the urgency of preventive interventions to mitigate syndromic manifestations in high-stress occupations. Full article

Introduction: Psychosocial functioning and body image are key dimensions of mental well-being and performance. Among professional dancers, competitive environments, aesthetic demands, and physical–emotional overload contribute to increased anxiety, stress, and mood disturbances, potentially impairing performance and heightening injury risk. Objective: To investigate longitudinal variations in psychosocial and emotional indicators among professional dancers throughout a season of rehearsals and performances. Methods: Thirteen dancers (9 women and 4 men) from a professional company were assessed across eight time points using the Brunel Mood Scale (BRUMS), State–Trait Anxiety Inventory (STAI-State), Recovery–Stress Questionnaire for Athletes (REST-Q 76 Sport), and Body Shape Questionnaire (BSQ). Data was analyzed using repeated-measures ANOVA with Bonferroni post hoc tests (p < 0.05). Results: Negative mood dimensions progressively increased (p < 0.01; η²p = 0.46, large), while vigor decreased (p = 0.03; η²p = 0.29, medium), indicating an inversion of the typical “iceberg” profile. Overall stress levels increased (p = 0.02; g = 0.53, power = 0.81) and perceived recovery declined (p = 0.04; g = 0.41, power = 0.78). State anxiety rose consistently (p < 0.01; η²p = 0.42), and body dissatisfaction, assessed via the BSQ, increased from “no concern” to “high concern” classifications (p = 0.03; g = 0.59, power = 0.84). Conclusions: Overall, the findings indicating a longitudinal pattern of increased psychometric strain indicators, inferred exclusively from psychometric trends, and conceptually consistent with a possible imbalance between perceived demands and perceived recovery, rather than reflecting objectively measured workload or recovery processes.

This article presents an approach to improving additive manufacturing (AM) processes by examining mental workload and human error during component fabrication using fused deposition modeling (FDM). A cross-sectional study involving experts and novice participants was conducted using a multi-stage approach based on Hierarchical Task Analysis (HTA), the NASA TLX Workload, and the Systematic Human Error Prediction Approach (SHERPA). A sample of two experts and two novice participants was studied. The HTA technique analyzed three main tasks: canister disk replacement, software configuration, and nozzle change. Each was divided into several subtasks. The mental workload results indicate that, among expert participants, the NASA-TLX dimensions with the highest average weighted scores were performance (77.5), time demand (65), and frustration (65). Among novice participants, the dimensions with the greatest impact were effort and frustration (90) and mental demand (87.5). The SHERPA method identified 19 human errors: 13 were action errors (68.4%), 3 were verification (checking) errors (15.7%), 2 were recovery errors (10.5%), and 1 was a selection error (5.2%). These results indicate differences in mental workload dimensions between experts and novices that may affect performance and human–machine interaction during additive manufacturing processes. Accordingly, preventive and corrective actions were recommended to minimize errors that can lead to material waste and financial losses. The study also identified low-to-high demand across key dimensions and a substantial number of errors in interactions with AM interfaces. Full article

Traditional methods to learn soft-tissue surgical procedures rely on cadaver labs or patient-based learning, which are costly and geographically limited, and raise ethical questions. Virtual reality (VR) with haptic feedback offers a scalable alternative, but most current platforms emphasize bone-based rather than soft-tissue procedures learned by feel. We developed a VR+haptic simulation for preoperative training of retropubic midurethral sling (MUS) surgery. This study examines the usability of this platform with thirteen expert urogynecologic surgeons and subsequently makes improvements (e.g., in haptics) to evaluate the platform with twelve trainees based on the NASA Task Load Index for workload and a UTAUT-informed usability survey. Objective performance scores were recorded as participants completed up to four levels of increasing realism and difficulty, starting with a transparent body and a reference surgical trajectory. Trainees reported high usability, immersion, and engagement. Experts rated the platform as valuable for sling training and skill assessment. NASA-TLX results indicated low physical and temporal demand, low mental demand and frustration, and moderate effort. These findings suggest that SurgicalEd VR is acceptable and has appropriate workload characteristics for surgical education. Future studies could examine how using VR+ haptic training improves intraoperative performance. Full article

This systematic review examines how gender shapes exposure to and experiences of psychosocial risks in the workplace. Drawing on 89 empirical studies published between 2010 and 2024, the review synthesizes evidence from occupational health psychology, gender studies, and organizational research. Searches were conducted in PubMed, Web of Science, Scopus, CINAHL, and PsycINFO, and included empirical studies published in English and Spanish. Following PRISMA guidelines, a qualitative thematic synthesis was conducted to integrate findings across diverse sectors, populations, and methodological approaches. The evidence reveals persistent gendered patterns in psychosocial risk exposure and outcomes: women are more frequently exposed to emotionally demanding and relational forms of work and report poorer mental health outcomes; men experience performance-driven strain linked to workload, competition, and reward insecurity more often; and transgender and non-binary workers face additional psychosocial burdens associated with stigma, discrimination, and minority stress. Across the literature, structural and cultural determinants—such as occupational segregation, unequal recognition, and gendered organizational norms—emerge as central mechanisms underlying these disparities. Theoretical frameworks including effort–reward imbalance, demand–control, work–family conflict, organizational climate, and minority stress collectively contribute to explaining how gendered psychosocial risks are produced and sustained. Overall, the review underscores the need to move beyond individualistic and binary models of psychosocial risk toward gender-responsive approaches that account for structural, relational, and identity-based dimensions of work, thereby informing research and organizational strategies aimed at promoting equitable and sustainable well-being at work.

Background/Objectives: Dementia is a major global health challenge, with prevention strategies increasingly focusing on the preclinical stage of Subjective Cognitive Decline (SCD). This study aimed to evaluate the feasibility, usability, and acceptability of a 5-week immersive virtual reality and telemedicine-based multicomponent intervention, combining cognitive training with a health and lifestyle education program, in individuals with SCD. Methods: Thirty-nine individuals with SCD were randomly allocated to either the multi-component intervention (MC-I; n = 19) or the cognitive-only intervention (CO-I; n = 20). Both programs were delivered remotely via head-mounted displays and monitored through a telemedicine platform. Feasibility was assessed through retention, adherence, and safety measures. Post-intervention, participants completed the System Usability Scale (SUS), User Satisfaction Evaluation Questionnaire (USEQ), NASA Task Load Index (NASA-TLX), and Simulator Sickness Questionnaire (SSQ). Results: High feasibility was demonstrated by a 100% retention rate and 92% adherence. Both groups reported “excellent” usability (SUS mean: 84.04) and high satisfaction (USEQ mean: 26.7), with no significant differences between groups. The NASA-TLX reflected a moderate workload (mean: 56.1), characterized by high mental demand but low frustration. Safety was confirmed by remarkably low SSQ scores, indicating negligible cybersickness. Conclusions: The results provide strong preliminary evidence that a home-based, multi-component IVR intervention is safe, usable, and highly accepted by individuals with SCD. Integrating lifestyle education does not increase the perceived burden, supporting the scalability of this remote digital approach for dementia secondary prevention. Full article

Automated alert systems for air traffic controllers (ATCOs) often generate many nuisance visual warnings that ATCOs routinely ignore, potentially compromising safety. To explore an alternative modality, we tested vibrotactile alerts to warn ATCOs of aircraft entering their sector. In two experiments with 118 novice participants, Experiment 1 compared a visual color-change alert to a simple vibrotactile pulse. Using a high-difficulty scenario with nine handoffs, simple vibrotactile alerts elicited significantly faster response times than visual alerts without increasing mental workload or degrading performance. In Experiment 2 we added gradual and continuous vibrotactile alerts, but no further advantage emerged from their implementation. Nevertheless, all vibrotactile alerts reliably captured attention without adverse effects, demonstrating the feasibility of non-invasive tactile devices to augment or replace visual alerts and help ATCOs allocate their cognitive resources more effectively. However, this is an exploratory study at a pre-operational stage without direct practical implications for ATC planning and control. Full article

New luminescent coatings are increasingly being used in highway tunnels to address inadequate internal lighting conditions. However, there is currently a lack of scientifically reliable methods to evaluate the effectiveness of these paints in improving lighting conditions, reducing driver psychological stress, and quantifying these impacts. This study utilized new luminescent coatings to improve tunnel lighting conditions, conducting real-vehicle tests to measure drivers’ physiological parameters including pupil diameter and heart rate. It examined the mechanisms through which variations in lighting conditions within highway tunnels affect the psychological workload of drivers. A hierarchical analysis–fuzzy comprehensive evaluation (AHP-FCE) method was adopted to develop a quantitative evaluation system for highway tunnel driving psychological load. The results indicate that variations in tunnel lighting substantially influence the psychological workload experienced by drivers during operation. The new luminescent coatings effectively enhanced tunnel lighting conditions, increasing average brightness and illuminance by 37.71% and 40.95%, respectively. Following lighting improvements, pupil diameter variation rates during tunnel entry and exit phases decreased by 35.37% and 10.06%, respectively, while heart rate variation rates decreased by 12.50% and 4.36%. Quantitative analysis of driver mental load revealed a comprehensive score of 0.6230 before lighting enhancement, which decreased to 0.2702 after improvements. This research introduces an innovative integrative framework that combines physiological parameter monitoring with the AHP-FCE method to quantitatively assess the psychological workload experienced by drivers in tunnel environments. This approach addresses a significant gap in the literature concerning the quantitative relationship between tunnel lighting optimization and drivers’ psychological workload responses. Full article

The mental health of students in university has become an increasingly pressing concern due to rising academic pressure, career uncertainty, and major life transitions. Identifying students’ psychological support needs requires an understanding of the challenges they face, as well as their expectations regarding support forms, intervention methods, and service providers. This study employed a mixed-methods cross-sectional design, combining large-scale questionnaire surveys (701 respondents) with qualitative interviews to assess the mental health status and psychological support needs of students at economics universities in Vietnam. The findings reveal that students commonly experience negative emotional states, particularly anxiety related to academic workload, financial instability, personal health, and future career orientation. A proportion of students reported depressive symptoms such as persistent sadness, prolonged stress, and physiological disturbances including insomnia and disordered eating. While severe behavioral disorders are uncommon, signs of declining academic motivation, social withdrawal, and weakened interactions with lecturers are evident. Students express a strong demand for mental health support, especially in career guidance, learning strategies, emotional regulation, and interpersonal problem-solving. Individual, professional, confidential counseling services are the most preferred forms of support, highlighting the need for a comprehensive mental health and psychological support system tailored to the context of Vietnamese universities.

Work-related stress is one of the most important health problems arising from the interaction between workers and the psychosocial conditions of their work environment. One of its most common physical consequences is musculoskeletal pain, especially in the back and neck. This study analyzes the effectiveness of an intervention program combining Global Postural Re-Education and Virtual Reality techniques to improve psychosocial working conditions and overall mental health. A quasi-experimental design was implemented with four independent groups: virtual reality alone, postural re-education with a hammock-type device, a combination of virtual reality and postural re-education, and rest break with music (placebo). The CarMen-Q questionnaire was used to assess psychosocial work factors, while the GHQ-28 was administered to evaluate general mental health. Forty-four participants completed ten intervention sessions over two consecutive weeks. The results showed a significant overall improvement in perceived work conditions and mental health after participation. The combined VR + RPG condition produced the greatest reduction in emotional demands and performance pressure, whereas the simple rest condition yielded the greatest improvement in psychological well-being. These findings suggest that brief interventions integrating physical and cognitive relaxation components can effectively reduce work-related stress and promote occupational well-being. Full article

(1) Background: With the increasing complexity of public safety duties, police officers are frequently exposed to high-pressure, high-risk environments. They face multiple stressors, including workload demands, societal expectations, supervisory pressure, and emergencies. Such factors can impair their mental health and emotional suppression capacity. (2) Methods: This preliminary qualitative investigation examines police officers’ perceptions of stress-related suppression processes through a literature review and semi-structured in-depth interviews with a small number of officers, employing qualitative content analysis. The research focuses on officers’ reported coping strategies, experiences with psychological counseling systems, and views on institutional mechanisms such as officer screening and emotional support structures. (3) Results: The findings reveal that participants reported generally lacking adequate emotional expression channels, leading to emotional dysregulation, outbursts, and burnout. Social support, supervisor attitudes, and flexible duty arrangements were perceived as key stress-mitigating resources. However, the utilization of current psychological counseling services remains low, primarily due to concerns regarding stigmatization and confidentiality. (4) Conclusions: This preliminary study recommends the development of a responsive mental health support framework for police agencies, emphasizing improvements in officer selection processes, mental health training, counseling accessibility, and organizational flexibility.

Reliable detection of contact states, such as the “mating” of connectors, is crucial for high-quality teleoperated assembly. Conventional systems relying solely on visual and continuous force feedback often fail to convey these discrete high-frequency transients due to the limited high-frequency rendering capabilities. This study investigates the effectiveness of augmenting visual and force feedback with vibrotactile and auditory cues for detecting connector mating. We conducted three experiments: (1) a mating detection task using recorded multimodal data ($N=10$), (2) a modality contribution analysis ($N=10$), and (3) a real-time robot connector insertion task ($N=10$). Results from the real-time task demonstrated that the proposed multimodal feedback significantly reduced the maximum contact force exerted after mating compared to the baseline visual-force condition ($p<0.001$), thereby enhancing physical safety. Furthermore, vibrotactile and auditory cues were found to be redundant yet complementary, providing robust cues even when one modality is compromised. Although subjective mental workload increased due to sensory integration, the significant improvement in detection clarity and safety justifies the multimodal approach. We conclude that providing transient vibrotactile and auditory cues is a highly effective strategy for compensating for the limitations of conventional force feedback in teleoperated assembly.

Background and Objectives: The COVID-19 pandemic has led to an unprecedented mental health crisis among workers in the healthcare field, with average burnout rates increasing from about 32% before the pandemic to 46–52% during peak times and post-traumatic stress disorder (PTSD) affecting 24–34% of frontline staff. The primary objective of this article is to synthesize evidence on the prevalence of burnout and PTSD among healthcare workers before and during the COVID-19 pandemic. The secondary objectives are: (a) to examine the mechanisms and empirical evidence linking clinician mental health to medical errors and patient safety outcomes and (b) to analyze the medico-legal implications of this relationship, including malpractice liability, institutional responsibility, and opportunities for policy reform. Materials and Methods: We conducted a narrative review searching PubMed (November 2025–January 2026) using predefined keyword combinations. Inclusion criteria comprised original research, systematic reviews, and meta-analyses examining mental health outcomes or patient safety among clinical staff. Data were synthesized narratively across five thematic domains. Results: Burnout prevalence increased from approximately 32% pre-pandemic to 46–52% during peak periods, with emotional exhaustion reaching 67.5% in some settings. PTSD rates rose to 24–34% among frontline staff, exceeding pre-pandemic levels of 15–20%, with ICU staff particularly affected (27–40%). Substantial overlap exists between conditions (86–98% comorbidity). Physician burnout is associated with 2.72 times higher odds of self-reported errors (95% CI: 2.19–3.37), with each point increase in emotional exhaustion raising the error risk by 5–11%. Mechanisms include cognitive impairment (reduced executive function, g = −0.39; impaired working memory, g = −0.36) and sleep disturbance. Malpractice litigation compounds psychological harm, increasing depression and suicidal ideation. Conclusions: This review, synthesizing data from over 500,000 healthcare workers, demonstrates bidirectional relationships among burnout, PTSD, and medical errors with significant medico-legal ramifications. Addressing this crisis requires systemic interventions including workload management, psychological support, blame-free reporting cultures, and policy reforms balancing accountability with recognition of system-level contributors to error.

Background/Objectives: Teacher burnout represents a complex cognitive-emotional syndrome characterized by the interplay between mental exhaustion and emotional dysregulation, threatening educational sustainability during crisis periods. This study employed comprehensive behavioral data analysis to investigate burnout syndrome patterns among Greek teachers during the COVID-19 educational crisis, aiming to identify risk factors and resilience patterns through multiple analytical approaches that capture the syndrome’s multidimensional nature. Methods: A cross-sectional study examined primary and secondary school teachers in Western Greece during the autumn of 2021. Stratified random sampling ensured representativeness across school levels, geographic locations, and employment types. Participants completed the Greek-adapted Maslach Burnout Inventory for Educators, which measured emotional exhaustion, depersonalization, and personal accomplishment. Behavioral data analysis integrated traditional statistical methods with advanced pattern recognition techniques, including classification trees for non-linear relationships, association analysis for behavioral patterns, and cluster analysis for profile identification. Results: The majority of teachers experienced high stress with inadequate coping capabilities. Classification analysis achieved high accuracy in predicting burnout severity, identifying emotional exhaustion as the primary predictor. Deputy teachers demonstrated severe cognitive-emotional strain compared to permanent colleagues across all dimensions, with dramatically reduced personal accomplishment and minimal resources. Association analysis revealed that combined low support and high workload more than doubled burnout risk. Three distinct profiles emerged: Resilient teachers, characterized by older age and permanent employment; At-Risk teachers, showing early warning signs; and Burned Out teachers, predominantly young and in precarious employment. Remote teaching, exceeding half of the workload, significantly increased strain. Multiple regression confirmed emotional exhaustion as the dominant syndrome predictor. Conclusions: Behavioral data analysis revealed complex cognitive-emotional patterns constituting burnout syndrome during educational crisis. Employment precarity emerged as the fundamental vulnerability factor, with young deputy teachers facing dramatically higher syndrome probability compared to supported senior permanent teachers. The syndrome manifests through cascading processes where cognitive overload triggers emotional exhaustion, subsequently reducing personal accomplishment. These findings provide an evidence-based framework for early syndrome identification and targeted interventions addressing both cognitive and emotional dimensions of teacher burnout. Full article
