Purpose: The assessment of endocrine status in elite athletes is typically linked to training load and perceived stress; however, the relationship between hormonal parameters and psychosomatic and stress indicators remains insufficiently understood. This study aimed to investigate the associations between endocrine status and stress, mood, and psychosomatic status indicators in elite handball players. Methods: In a cross-sectional study, salivary cortisol (with no strict control over wake-up time), testosterone, and—in female athletes—17-β-estradiol concentrations were assessed in 584 elite handball players aged 14–35 years using ELISA. Psychological variables were evaluated using the Perceived Stress Scale (PSS), Profile of Mood States (POMS), and the Health Behavior in School-aged Children Symptom Checklist (HBSC-SCL). Associations were examined using non-parametric tests and general linear models adjusted for age. Results: Hormonal and psychological variables demonstrated significant age-related trends. No significant associations were observed between hormonal parameters and perceived stress or mood disturbance (values for the general linear model (GLM) were all p > 0.05). In contrast, psychosomatic symptom severity was significantly associated with cortisol levels in male athletes (GLM, p < 0.001) and testosterone levels in female athletes (GLM, p = 0.009). Multivariate analyses confirmed the relevance of psychosomatic symptoms and indicated interaction effects between stress-related factors. Conclusion: Psychosomatic symptoms were more closely associated with endocrine status than with perceived stress or mood disturbance in elite handball players. However, these associations were characterized by relatively small effect sizes, indicating that psychosomatic symptoms explain only a limited proportion of the variance in hormonal parameters. These findings suggest that psychosomatic indicators may provide a more sensitive reflection of physiological strain and support the use of integrated monitoring approaches combining endocrine and psychosomatic measures in elite sport. In practical terms, routine monitoring of psychosomatic symptoms alongside hormonal measures may help practitioners to identify early signs of physiological strain and support timely adjustments in training load and recovery strategies.

Objectives: Effective operational functioning within the tactical domain requires a high integration of physical and psychological capacities under stressful conditions. This study investigated the impact of physical exertion at varying intensities (anaerobic and aerobic running) on subsequent change-of-direction speed (CODS) performance among police students, while evaluating the role of mental toughness (MT) and biological sex. Methods: Thirty police students (36.7% female) completed running protocols at different intensities (300-yard shuttle run and 2.4 km Cooper test), immediately followed by the Illinois Agility Test (IAT) to assess CODS performance. Mental toughness was evaluated using the Mental Toughness Index (MTI). Repeated-measures ANOVA and ANCOVA were used to analyze the main and interaction effects. Results: Initial repeated-measures ANOVA revealed that increasing running intensities significantly degraded CODS performance, demonstrating large main effects for both the anaerobic (F = 56.70, p < 0.001, η²_p = 0.661) and aerobic (F = 47.50, p < 0.001, η²_p = 0.621) protocols. After introducing mean-centered MT as a covariate, the main effect of Running Speed remained highly significant in both the anaerobic (F = 57.52, p < 0.001, η²_p = 0.673) and aerobic (F = 46.01, p < 0.001, η²_p = 0.622) models, with no significant univariate interaction effects involving MT or sex on the rate of decline. Mixed ANCOVA showed a significant main effect of sex on absolute IAT times under both anaerobic and aerobic conditions, with males consistently outperforming females. No significant differences in baseline MT scores were observed between sexes (p = 0.507). Conclusions: The findings demonstrate that physical fatigue robustly impairs CODS performance at a parallel rate for both male and female police students. Mental toughness does not neutralize the physiological rate of performance decline under acute fatigue. Practical training programs should integrate physical and psychological conditioning scenarios, while workload management protocols can be uniformly applied across biological sexes. Full article

Purpose: The well-being of dental students is crucial, yet it can be influenced by various factors, including academic stress and clinical practice. In this study, we aimed to assess the association of dental education with the quality of life (QoL) of dental students compared with the QoL of non-dental healthcare students, while also evaluating the QoL of all students across psychological, physical, social, and environmental domains. Materials and Methods: In this cross-sectional study conducted at King Abdulaziz University between December 2023 and March 2024, all undergraduate senior-year students from the faculties of dentistry, medicine, and pharmacy were surveyed with the World Health Organization Quality of Life scale (WHOQOL-BREF). Results: Of the 477 participants (372 men and 105 women), 174 were from the dental faculty, 152 from the faculty of pharmacy, and 151 from the faculty of medicine. The academic distribution comprised 32.9% fourth-year students, 30.6% fifth-year students, 12.8% sixth-year students, and 23.7% interns. Dental and non-dental students predominantly rated their QoL as “good” or “very good,” with the percentage of dental students who did so being slightly higher (73.0%) than that of non-dental students (71.6%). In contrast, more non-dental students reported higher satisfaction with health than dental students did (74.3% vs. 65.0%, respectively). Overall, dental students had lower QoL scores (mean 64.8 ± 14.1) than students in other health specialties did. Notably, no statistical difference was observed between student categories in the physical domain, whereas students in other health specialties demonstrated higher QoL scores than dental students did in the psychological, social, and environmental domains. Conclusions: This study underscores disparities in QoL among students in different health specialties, with dental students exhibiting lower scores in three domains. These findings emphasize the need for tailored interventions in dental education to address stressors and enhance mental health support. Full article

Background: Tobacco smoking cessation is a complex process influenced by biological, psychological, and social factors. Despite the availability of effective cessation interventions, relapse remains common among smokers attempting to quit. This study aimed to identify factors associated with previous smoking relapse and nicotine dependence among smokers attending anti-smoking clinics in Abha City, Saudi Arabia. Methods: An analytical comparative cross-sectional study was conducted among 330 adult Saudi smokers attending the Abha Anti-smoking Clinic and the Erada Anti-smoking Clinic. Previous smoking relapse was defined as having one or more unsuccessful smoking cessation attempts after a period of abstinence. Data were collected using a structured interviewer-administered questionnaire covering sociodemographic characteristics, smoking history, nicotine dependence, withdrawal symptoms, motives for smoking cessation, and relapse-related factors. Nicotine dependence was assessed using the Fagerström Test for Nicotine Dependence (FTND). Descriptive statistics, chi-square tests, and multivariable logistic regression analyses were performed. Results: Most participants were male (84.2%) and aged 20–39 years (59.4%). Smoking initiation most commonly occurred between 15 and 20 years of age (68.8%), while 66.4% reported previous quit attempts. Nervousness (84.2%) and stress or tension (74.2%) were the most frequently reported withdrawal symptoms. High and very high nicotine dependence were reported by 26.1% and 14.2% of participants, respectively. High nicotine dependence (AOR = 1.39, 95% CI: 1.15–1.69, p = 0.001) and very high nicotine dependence (AOR = 1.62, 95% CI: 1.21–2.17, p < 0.001) were independently associated with greater odds of previous smoking relapse. Attendance at the Erada Anti-smoking Clinic was associated with lower odds of relapse (AOR = 0.52, 95% CI: 0.29–0.91, p = 0.021). Conclusions: Higher nicotine dependence was independently associated with previous smoking relapse among smokers attending anti-smoking clinics. Comprehensive cessation programs integrating behavioral counseling, pharmacological treatment, and sustained follow-up may improve long-term abstinence and reduce relapse. Full article

Background/Objectives: Shift work is associated with circadian disruption, sleep disturbances, and psychological distress, all of which may influence both reflux-related symptoms and temporomandibular disorder (TMD)-related complaints. However, the relationships among reflux-related symptom burden, TMD severity, oral parafunctional behaviors, and psychological distress in healthcare professionals remain insufficiently understood. To evaluate the association between reflux-related symptom burden, assessed using the Gastroesophageal Reflux Disease Health-Related Quality of Life (GERD-HRQL) questionnaire, and TMD severity among healthcare professionals, and to investigate the potential roles of shift work, oral parafunctional behaviors, and psychological distress in this relationship. Methods: This cross-sectional observational study included healthcare professionals working at a tertiary hospital. Data were collected using validated questionnaires, including the GERD-HRQL, Fonseca Anamnestic Index, Oral Behavior Checklist (OBC), Depression Anxiety Stress Scale-21 (DASS-21), and Epworth Sleepiness Scale (ESS). Participants were categorized as shift workers (≥4 night shifts/month) and non-shift workers. Correlation and multivariable regression analyses were performed. Results: A total of 240 participants were included. Higher GERD-HRQL scores were positively correlated with TMD severity (r = 0.31, 95% CI: 0.19 to 0.42, p < 0.001), oral parafunctional behavior scores (r = 0.28, 95% CI: 0.16 to 0.39, p < 0.001), and DASS-21 stress scores (r = 0.35, 95% CI: 0.23 to 0.46, p < 0.001). Shift workers demonstrated significantly higher GERD-HRQL scores and TMD severity scores than non-shift workers, with small-to-moderate effect sizes. In multivariable analysis, higher TMD severity, OBC score, stress score, and shift-work exposure showed adjusted associations with higher GERD-HRQL scores. The model explained 32% of the variance in reflux-related symptom burden (R² = 0.32; adjusted R² = 0.29). Conclusions: Higher GERD-HRQL scores, reflecting reflux-related symptom burden rather than objectively confirmed GERD, showed weak to small-to-moderate associations with TMD severity, oral parafunctional behaviors, psychological distress, and shift-work exposure among healthcare professionals. These findings indicate co-occurrence of gastrointestinal, temporomandibular, behavioral, and psychosocial symptom domains within this occupational population. Longitudinal studies using objective diagnostic methods are required to clarify the directionality and clinical significance of these associations. Full article

Background/Objectives: Cortisol, a stress-related protein found in saliva, is occupying an increasingly crucial role in stress research. While stress was previously assessed solely using psychological scales, the addition of cortisol as a biomarker has enabled more accurate stress assessment. Previously, stress among shift workers was evaluated both subjectively and objectively using psychological scales and cortisol levels. However, the variety of available psychological scales led to a lack of consensus on which ones should be used. This study reviewed papers investigating the relationship between cortisol and psychological scales to determine which ones should be used together. Methods: We searched for original research papers examining the relationship between psychological scales and cortisol levels among shift workers during a 20-year period from 1 January 2006 to 31 December 2025. The data were organized using psychological scales. Results: In total, 308 papers were selected, and after excluding those that met the exclusion criteria, 19 were chosen. Across the 19 studies, 10 different psychological scales were associated with cortisol. The most frequently associated psychological scales with cortisol were the Maslach Burnout Inventory (MBI), which appeared in four out of seven studies, followed by the Visual Analog Scale and Zung Self-Rating Depression Scale, which appeared in one out of two studies. Conclusions: We believe that the MBI is the most appropriate stress scale to evaluate in conjunction with cortisol; however, further evaluation is needed, particularly research that measures salivary cortisol and stress-related psychological scales using appropriate sampling methods.

Mental fatigue is an increasingly important concern among collegiate athletes whose academic–athletic roles require sustained cognitive effort, emotional regulation, and recovery across overlapping performance contexts. This structured narrative review synthesizes behavioral science, sport psychology, and athlete mental health literature to clarify how perceived stress, competitive anxiety, and psychological resilience may interact in the development and regulation of mental fatigue among collegiate athletes. Rather than treating mental fatigue as simple tiredness or an isolated performance symptom, this review conceptualizes it as a cognitive–emotional and psychobiological outcome shaped by stress appraisal, attentional load, effort regulation, and resource depletion. The main contribution of this review is to integrate previously separate lines of research into a collegiate-athlete-focused behavioral science framework in which perceived stress is positioned as an upstream appraisal-based condition, competitive anxiety as a proximal emotional mechanism, and psychological resilience as a dynamic regulatory resource that may buffer fatigue-related vulnerability. Tennis and Chinese/non-Western collegiate sport contexts are used as illustrative applications rather than exclusive empirical targets, highlighting how individual accountability, academic–athletic role demands, cultural expectations, and support structures may shape fatigue processes. This review also distinguishes established empirical evidence from theoretical inference and identifies key gaps in measurement heterogeneity, methodological transparency, longitudinal evidence, and culturally diverse collegiate athlete research. By refining the stress–anxiety–fatigue pathway and identifying resilience, recovery, and contextual support as important regulatory factors, this review provides a conceptual foundation for future empirical testing and for more targeted behavioral interventions to support collegiate athlete well-being and performance sustainability.

Psychological stress can affect female reproductive function through behavioral, endocrine, ovarian, and oxidative mechanisms. Antioxidant supplements have therefore attracted attention for their potential to mitigate stress-related reproductive alterations. Coenzyme Q10 (CoQ10) is a lipid-soluble quinone involved in mitochondrial energy metabolism and is widely used as a dietary supplement. However, whether CoQ10 modulates female reproductive responses to repeated psychological stress remains unclear. Although water avoidance stress (WAS) is a well-established psychogenic stress model, its effects on female reproductive outcomes are still not fully defined. In this study, we examined how repeated WAS affects female reproductive outcomes and whether CoQ10 modifies these effects. Twenty-eight regularly cycling female rats were assigned to sham control, WAS, CoQ10, or WAS + CoQ10 groups. WAS was applied for 1 h/day for 10 days, and CoQ10 was administered orally at 100 mg/kg/day. Repeated WAS did not significantly alter sexual incentive motivation parameters, reproductive hormones, corticosterone, total antioxidant capacity (T-AOC), 8-hydroxy-deoxyguanosine (8-OHdG), or mast cell count under the present experimental conditions (all p > 0.05). However, WAS reduced male-directed active investigation time (p = 0.008) and male investigation preference ratio (p = 0.024), increased absolute ovarian and adrenal gland weights (p = 0.035 and p = 0.016, respectively), reduced primordial follicle number (p = 0.030), decreased germinative epithelium thickness (p = 0.017), lowered VEGF histoscore (p = 0.033) regardless of CoQ10 treatment, and reduced corpus luteum angiogenesis in animals not receiving CoQ10 (p = 0.030). CoQ10 reduced total investigation time toward the male (p = 0.032), male investigation preference ratio (p = 0.037), 17-β estradiol (E2) (p = 0.003), testosterone (p = 0.021), and germinative epithelium thickness (p < 0.001) regardless of WAS exposure. CoQ10 also decreased kisspeptin-1 levels under non-stressed conditions (p = 0.010), while increasing corpus luteum angiogenesis under stress conditions (p = 0.003). Overall, repeated WAS produced selective behavioral and ovarian alterations rather than broad reproductive dysfunction. CoQ10 was not associated with a broadly protective or uniformly beneficial profile in this model, and its endocrine, behavioral, and ovarian effects should be interpreted with caution. Full article

Purpose: The purpose of this paper is to provide an integrative review of Positive Psychology in contemporary organizational contexts, examining how psychological resources such as Psychological Capital, Emotional Intelligence, Mindfulness, Psychological Safety, Self-Determination Theory, and Positive Leadership contribute to employee well-being, flourishing, and organizational effectiveness. Design/Methodology/Approach: This study adopts a narrative integrative literature review approach, synthesizing recent theoretical and empirical research in Positive Organizational Psychology, Organizational Behavior, and Human Resource Management. The review integrates foundational theories with contemporary empirical findings published in high-impact academic journals to develop a comprehensive conceptual framework. Findings: The findings indicate that Positive Psychological constructs are consistently associated with higher levels of employee engagement, job satisfaction, performance, resilience, and flourishing, while reducing burnout, stress, and turnover intentions. Psychological Capital emerges as a key malleable resource, while Mindfulness and Emotional Intelligence enhance self-regulation and interpersonal effectiveness. Originality: The paper integrates multiple streams of Positive Psychology into a unified conceptual model, combining individual-level psychological resources with motivational and organizational-contextual factors. Research limitations/implications: As a narrative review, the study does not include primary empirical data or statistical testing. Future research should empirically validate the proposed integrative framework using longitudinal and cross-cultural designs. Practical implications: Organizations can enhance employee well-being and performance by implementing Psychological Capital Interventions, mindfulness-based programs, strengths-based development, and psychologically safe leadership practices. Social implications: The findings highlight the broader societal value of fostering psychologically healthy workplaces that promote sustainable employment, mental health, and human flourishing.

This study explores how small business owners in the hospitality sector in Jordan cope with the threats from the adjacent Gaza-Israel conflict. While crisis research in tourism has focused mainly on macro-level indicators and managerial responses to events, less is known about the psychological processes used by small hospitality business owners to evaluate such geopolitical tensions and translate them into coping reactions. Using a transactional perspective on stress, appraisal, and coping, this study explores how business owners perceive threats and adopt coping mechanisms under unstable geopolitical conditions. Semi-structured interviews with small hospitality business owners in Jordan reveal that geopolitical conflict is not automatically perceived as a catastrophic threat. Rather, threat emerges through a person–environment transaction when owners interpret the conflict as harmful, uncertain, or beyond control within their business context. The findings further reveal that owners combine problem-focused coping, such as operational and marketing adjustments, with emotion-focused coping, such as pragmatic optimism, positive reappraisal, goal resetting, and the normalization of instability. By foregrounding cognitive appraisal and coping in this way, the study extends tourism and hospitality crisis research beyond macro-level outcomes and offers practical insights into strengthening the resilience of small hospitality businesses in geopolitically unstable tourism regions.

Background: Micromanagement is an extensively prevalent yet relatively under-theorized management process in healthcare organizations. This narrative review synthesizes the literature on micromanagement and related leadership practices in healthcare, focusing on its antecedents, manifestations, consequences, and mitigation strategies. Methods: A structured literature search was conducted on 10 May 2024 across eight electronic databases. Eligible studies included qualitative, quantitative, mixed-methods, and applied studies published between 2003 and 2024. The main outcomes were the underlying causes and behavioral measures of micromanagement, examined directly, or closely related constructs such as excessive supervision, reduced autonomy, authoritarian leadership, toxic leadership, and controlling managerial behavior. The secondary outcomes involved organizational and patient-related effects and their respective interventions. Results: A total of twelve studies were selected. The identified antecedents of micromanagement were authoritarian leadership styles, autocratic and toxic leadership personality traits, overly intrusive supervisory practices, poor employee empowerment, complicated regulation, unclear definition of professional roles, and inherent structural challenges. Micromanagement behavior was seen in authoritative decision-making, transactional supervision, systematic reduction in employee autonomy, and institutionalized distrust. The consequences recorded include high levels of occupational stress, poor organizational productivity, poor quality of healthcare services, high employee turnover rates, and psychological problems. Conclusions: This review represents a preliminary conceptual synthesis of the literature that addresses micromanagement in healthcare. The evidence base is inconsistent, with many studies focusing on constructs that relate to micromanagement while not studying it directly. In future research, validated tools to assess micromanagement should be designed, as well as leadership interventions that benefit both workplace and patient outcomes. Full article

Background: The aim of this study was to comprehensively analyze the relationships within a multimodal biomarker panel, including endothelial function indicators, markers of systemic inflammation and myocardial stress, metabolic homeostasis parameters, and an indicator of microstructural damage to nerve tissue in CAD patients with or without type D personality. Methods: This exploratory, cross-sectional, observational study included 72 patients with coronary artery disease. All patients underwent psychological testing (evaluation of type D personality and determination of depression and anxiety levels) and biomarker measurements. The multimodal biomarker panel included measurements of metabolic homeostasis parameters (glucose, total cholesterol, creatinine, insulin, 1,5-anhydroglucitol), markers of systemic inflammation (CRP, IL-6), myocardial stress (NTproBNP), endothelial function parameters (eNOS, EDN1, ADMA, VEGF), and an indicator of microstructural damage to nerve tissue (S100B protein). Results: Biomarker levels revealed no statistically significant differences between the groups with and without personality type D. In personality type D, a direct correlation was found between the level of the brain tissue damage marker S100B and eNOS concentration (R = 0.578; p = 0.006), which was not observed in non-type D. In patients with personality type D, a significant inverse correlation was confirmed between ADMA and creatinine levels (R = −0.524; p = 0.015). In individuals with non-type D personality, a direct correlation was established between total cholesterol levels and VEGF (R = 0.342; p = 0.014). Conclusions: In patients with coronary heart disease, psychological distress (type D) is associated not with an isolated change in biomarker concentrations but with a transformation of the entire structure of their relationships. Personality type D is characterized by a transition from the physiological autonomy of systems to the formation of pathogenetic relationships between them, indicating a decrease in adaptive reserve.

Despite heightened physical risks during the COVID-19 pandemic, older adults often reported better mental health than younger adults, suggesting significant resilience. We used longitudinal qualitative data to examine how difficulties and positive experiences contributed to this resilience. Weekly COVID-related difficulties and positive experiences were collected using internet surveys over eight weeks from 247 respondents aged 51–95 (M = 71.1, SD = 7.3). Nearly all identified at least one difficulty, and 76% had problems three or more times. Longitudinal thematic analysis (LTA) revealed that most were consistent in how they described they difficulties, including problems with everyday protective activities, psychological distress, social isolation, and cultural divide (disagreements over public health policy). Although 78% identified at least one positive, less than half (42%) did so at three or more time pints. Positive experiences were more diverse across time, but some reported greater interpersonal connection by utilizing technology to increase social contacts. LTA revealed three stances towards positive experiences: active efforts, appreciative efforts (observation), and mixed efforts. While trait resilience was unrelated to the themes, the mixed approach towards positive experiences was associated with lower anxiety at the last assessment, emphasizing the importance of positive experiences during stress.

The rapid evolution of Padel in Saudi Arabia (SA) has positioned the sport as a popular recreational and social activity, mainly among young adults. However, limited research has examined how different forms of sport motivation are associated with mental health outcomes in this emerging context. Drawing on Self-Determination Theory (SDT), this study investigated the associations between intrinsic and extrinsic motivation and depression, stress, and anxiety among Padel players in SA. A quantitative, cross-sectional online survey was conducted with a sample of 475 players, the majority of whom were aged 17–35 and held at least a bachelor’s degree. Data were analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM) to evaluate the relationships between multidimensional motivation factors and mental health symptoms. The findings revealed a nuanced, at times paradoxical, pattern of relationships. Intrinsic motivation to experience stimulation (engaging in an activity because of the positive sensations, excitement, enjoyment, or stimulation that the activity itself provides, rather than for external rewards or pressures) was consistently associated with lower levels of depression, stress, and anxiety, suggesting that enjoyment-driven involvement is associated with better mental health outcomes. In contrast, intrinsic motivation to accomplish was positively correlated with all three mental health indicators, indicating that achievement-oriented engagement might intensify emotional pressure. Among extrinsic motivations, external regulation was significantly associated with poorer mental health outcomes. In contrast, introjected regulation unexpectedly displayed a negative association with psychological distress, demonstrating a potentially adaptive role in this setting. Identified regulation, however, was not significantly associated with any mental health symptoms. These results underscore the “double-edged” nature of sport motivation, showing that not all internal or external motives yield uniformly positive consequences. The study contributed to the growing literature by providing a context-specific understanding of how motivational dynamics function within a rapidly growing sport in Saudi Arabia. In practice, the findings suggested that enjoyment-based involvement was associated with more favourable mental health outcomes, whereas performance-related pressures might be associated with less favourable outcomes.

High-intensity functional concurrent training (HIFCT) has emerged as a form of training characterized by constantly varied functional movements adapted to individual fitness levels. Previous studies have reported positive effects on muscular strength, cardiorespiratory fitness, body composition, and psychological well-being; however, evidence regarding HIFCT interventions in school-aged children remains limited. Therefore, the aim of the present study protocol is to evaluate the effects of an 8-week HIFCT programme on muscular strength, cardiorespiratory fitness, body composition, anxiety, stress, and self-esteem in children aged 10–12 years. Physical fitness, anthropometric variables, and psychological outcomes will be assessed before and after the intervention using validated field-based tests and questionnaires. This study may provide novel evidence regarding the feasibility, safety, and potential effects of HIFCT programmes in the school setting. The study protocol was registered at ClinicalTrials.gov (NCT07552844) and approved by the Córdoba Research Ethics Committee (IMIBIC, Córdoba, Spain; protocol code SICEIA-2025-000408). Full article
