Burnout and psychological distress among Hispanic nurses across Illinois and New York hospitals: Implications for structural and person-centered solutions.

BACKGROUND: Despite high levels of burnout and psychological distress among nurses, few studies have evaluated these outcomes among Hispanic nurses. PURPOSE: To evaluate the differences in job-related and psychological well-being outcomes for Hispanic and non-Hispanic White nurses and the association of nurse work environments. METHODS: Cross-sectional analysis of the 2021 RN4CAST-New York-Illinois nurse survey. Multilevel logistic regression models examined the association between nurse ethnicity and job-related outcomes and psychological well-being. DISCUSSION: Our sample included 798 (10.7%) Hispanic and 6,642 (89.3%) non-Hispanic White nurses in 249 hospitals. In unadjusted models, Hispanic ethnicity was associated with higher odds of burnout (odds ratio (OR) 1.21, 95% confidence interval (CI): 1.03-1.42), which diminished when considering the work environment (OR 1.16, 95% CI: 1.01-1.35) and nurse characteristics (i.e., age) (OR 1.01, 95% CI: 0.83-1.21). CONCLUSION: Equity-driven solutions to support the well-being of Hispanic nurses should consider a focus on the needs of young Hispanic nurses and include increased support in work environments.

Examining the emotional healing process through bibliotherapy in adolescents with cancer: A qualitative descriptive study.

PURPOSE: This study aimed to investigate how interactive bibliotherapy impacted the emotional healing process of adolescents with cancer, drawing upon the three-stage emotional healing process theory-identification, catharsis, and insight. METHOD: A qualitative descriptive study was conducted on data from 14 adolescents, aged 10-19 years, diagnosed with or relapsing from leukemia or osteosarcoma within the past two years. Participants received two interactive bibliotherapy sessions using The Rabbit Listened and You Are Special. Data were collected through semistructured interviews and content analyzed. RESULTS: Analysis identified six themes in The Rabbit Listened and eight in You Are Special. Adolescents primarily engaged in identification, empathizing with protagonists and recalling personal experiences. They underwent catharsis, releasing negative emotions and fostering positivity. Insights emerged on companionship, listening, and others' criticism. CONCLUSIONS: Our study validates the use of the three-stage emotional healing process in interdisciplinary bibliotherapy for understanding emotional changes in adolescents with cancer. It sheds light on their concerns and coping strategies. Healthcare practitioners can utilize interactive bibliotherapy based on this framework to initiate therapeutic communication with adolescent cancer patients and improve interventions and care.

Spiritual needs of women with breast cancer: A structural equation model.

PURPOSE: The purpose of this study was to develop a structural equation model (SEM) to explore the factors influencing the spiritual needs of breast cancer patients. METHODS: A cross-sectional study was conducted in the breast surgery department of a tertiary hospital in China from September 2020 to December 2020; convenience sampling and questionnaires were used to facilitate sampling and data collection. A total of 220 female breast cancer patients were included in the study. The data were analysed using multiple linear regression and structural equation modelling. RESULTS: Compared with patients with other diseases, patients with breast cancer have greater spiritual needs (76.16 ± 13.19). Multivariate analysis revealed that religious beliefs, education level, social support, and resilience are important factors affecting the mental health of women with cancer (p < 0.05). The structural equation model fit well (RMSEA = 0.056, χ2p = 0.002). Social support directly affected spiritual needs (ß = 0.607, p < 0.001) and indirectly affected spiritual needs through resilience (ß = 0.353, p < 0.001). Resilience directly affected spiritual needs (ß = 0.386, p < 0.05). Education level indirectly affected spiritual needs through social support (ß = 0.307, p < 0.001). CONCLUSION: This study provides a theoretical basis for intervention measures to improve the spiritual needs of female breast cancer patients. Paying more attention to social support and resilience may help solve the problem of meeting the high spiritual needs of breast cancer patients. Further research is needed to develop interventions.

Post-traumatic stress disorder symptoms following exposure to acute psychological trauma in children aged 8-16 years in South Africa: protocol for the Sinethemba longitudinal study.

INTRODUCTION: Children exposed to trauma are vulnerable to developing post-traumatic stress disorder (PTSD) and other adverse mental health outcomes. In low-and middle-income countries (LMICs), children are at increased risk of exposure to severe trauma and co-occurring adversities. However, relative to high-income countries, there is limited evidence of the factors that predict good versus poor psychological recovery following trauma exposure in LMIC children, and the role of caregiver support in these high-adversity communities. METHODS AND ANALYSIS: We will conduct a longitudinal, observational study of 250 children aged 8-16 years and their caregivers in South Africa, following child exposure to acute trauma. Dyads will be recruited from community hospitals following a potentially traumatic event, such as a motor vehicle accident or assault. Potential participants will be identified during their hospital visit, and if they agree, will subsequently be contacted by study researchers. Assessments will take place within 4 weeks of the traumatic event, with 3-month and 6-month follow-up assessments. Participants will provide a narrative description of the traumatic event and complete questionnaires designed to give information about social and psychological risk factors. Child PTSD symptoms will be the primary outcome, and wider trauma-related mental health (depression, anxiety, behavioural problems) will be secondary outcomes. Regression-based methods will be used to examine the association of psychosocial factors in the acute phase following trauma, including caregiver support and responding, with child PTSD and wider mental health outcomes. ETHICS AND DISSEMINATION: Ethical approvals have been granted by Stellenbosch University and the University of Bath, with additional approvals to recruit via hospitals and healthcare clinics being granted by the University of Cape Town, the Department of Health and the City of Cape Town. Study findings will be disseminated via publication in journals, workshops for practitioners and policy-makers, and public engagement events.

Screening for psychosis risk in primary mental health care services - Implementation, prevalence and recovery trajectories.

OBJECTIVES: Early interventions improve outcomes for people at high risk of psychosis and are likely to be cost saving. This group tends to seek help for emotional problems - depression and anxiety - via primary care services, where early detection methods are poor. We sought to determine prevalence rates of high risk for psychosis in UK primary care mental health services and clinical outcomes following routinely delivered psychological therapies. METHODS: We used a brief screen designed for settings with low base rates and significant time constraints to determine prevalence of high risk for psychosis in UK 'Talking Therapies' services. We examined socio-demographic characteristics, presenting problems and recovery trajectories for this group, compared with people not at risk of psychosis. RESULTS: A 2-item screen selected for specificity yielded a prevalence rate of 3% in primary care mental health services. People at elevated risk of psychosis were younger and more likely to report at least one long-term physical condition. This group presented with higher levels of depression, anxiety and trauma symptoms at assessment and were less likely to have recovered at the end of treatment, compared to people not at risk. CONCLUSIONS: Very brief screening tools can be implemented in busy health care settings. The 3% of referrals to UK primary care psychological therapies services at elevated risk of psychosis typically present with more severe symptoms and greater levels of comorbidity and may require augmented interventions to recover fully.

Navigating the depths: exploring seafarers' psychological well-being on board, anchored by the mediating role of resilience and loneliness.

BACKGROUND: This study investigates seafarers' loneliness as a mediating variable between psychological well-being and resilience, and tests resilience as a mediating variable between psychological well-being and loneliness. It also examines the challenges faced by seafarers on different types of ships and evaluates the mediating roles of resilience and loneliness. MATERIALS AND METHODS: The research uses descriptive data analysis, reliability analysis, correlation analysis, and mediation analysis with bootstrap-based regression models. An online survey was conducted with 471 active Turkish seafarers using a sociodemographic questionnaire and three standardized scales measuring psychological well-being (PW), loneliness at work (LAW), and psychological resilience (PR). Data were collected between 01/07/2023 and 01/09/2023. RESULTS: The findings indicate that ship type is a significant factor in the mediating roles of loneliness at work and psychological resilience. There is a partial mediating role of loneliness at work and resilience in psychological well-being across different ship types. Specifically, loneliness at work partially mediates the relationship between psychological resilience and psychological well-being among seafarers on tanker or bulk carrier vessels, but not on container vessels. CONCLUSIONS: The study concludes with suggestions to address the mental health challenges faced by seafarers, emphasizing the importance of ship type in the mediating roles of loneliness and resilience. Regarding the mediating role of loneliness at work, it has been determined that there is partial mediation between psychological resilience and psychological well-being among seafarers working on tanker or bulk carrier vessels. However, on container vessels, loneliness at work does not mediate the relationship between psychological well-being and psychological resilience. Based on these findings, the authors conclude by offering a range of helpful solutions to address this problem.

Psychological and Academic Adaptation Through Universal Ethnic Studies Classes: Results of a Natural Experiment.

Schools in the United States are increasingly offering ethnic studies classes, which focus on exploring students' ethnic-racial identities (ERI) and critical analysis of systemic racism, to their diverse student bodies, yet scant research exists on their effectiveness for students of different ethnic-racial backgrounds in multiracial classrooms. A policy change to require all high school students in one school district to take an ethnic studies class facilitated a natural experiment for comparing the effects of quasi-random assignment to an ethnic studies class (treatment) relative to a traditional social studies class (control; e.g., U.S. Government, Human Geography). Student surveys and school administrative data were used to compare students' ERI development, well-being, and academic outcomes across ethnic studies and control classes. Participants (N = 535 9th graders; 66.1% ethnic studies) had diverse ethnic-racial (33.5% non-Latine White, 29.5% Black, 21.1% Latine, 10.7% biracial, 2.8% Asian, 2.2% Native American) and gender identities (44.7% female, 7.1% non-binary). Ethnic studies students reported marginally higher ERI exploration and resolution than controls, and sensitivity analyses showed a statistically significant effect on ERI among participants with complete midpoint surveys. Higher resolution was associated with better psychological well-being for all students and higher attendance for White students. Students with low middle school grades (GPA < 2.0) had better high school grades in core subjects when enrolled in ethnic studies than the control class. Overall, the results of this natural experiment provide preliminary support for ethnic studies classes as a method for promoting ERI development, well-being, attendance, and academic achievement for students from diverse ethnic-racial backgrounds.

From Networking to Attitudinal Outcomes: Psychological Capital as a Mediator.

Building on conservation of resources (COR) theory and following recent recommendations, this study investigates the mediating role of Psychological Capital (PsyCap) in the relationships between networking behaviors and attitudinal outcomes (i.e., work engagement and work satisfaction). We propose that networking, as an investment of personal resources to gain access to other resources, contributes to the prediction of attitudinal outcomes. We surveyed 254 employees from a public Belgian administrative company. We use structural equation modelling and the bootstrapping method. PsyCap totally mediates the relationships between networking and both attitudinal outcomes. This study contributes to theoretical development by integrating Networking and PsyCap literatures into COR theory literature, and demonstrates the legitimacy of COR theory to explain these complex variables and their relationships.

Factors associated with self-management behaviors among Chinese adults with ischemic stroke: A cross-sectional study.

Background: In China, adults with ischemic stroke are getting younger. Additionally, following a stroke, they often neglect self-management (SM), which significantly impacts the rehabilitation process and treatment outcomes. Objective: This study aimed to describe SM behavior and examine the relationship between stroke prevention knowledge, life stress, family relationships, and SM behavior among adults with ischemic stroke. Methods: A total of 125 participants were recruited between October 2022 and March 2023 based on defined inclusion criteria. Research instruments included a demographic questionnaire, the Stroke Self-management Behavior Scale for Young Adults, the Stroke Prevention Knowledge Questionnaire, the Perceived Stress Scale, and the Brief Family Relationship Scale. Data were analyzed using descriptive statistics and Pearson's product-moment correlation. Results: The mean score of SM behavior was 88.1 out of 130 (SD = 16.5). Stroke prevention knowledge and family relationships showed a moderate positive significant relationship with SM behavior (r = 0.39, r = 0.34, p <0.001, respectively). Life stress had a significant negative relationship with SM behavior (r = -0.33, p <0.001). Conclusion: The findings offer insights for nurses to develop nursing interventions to promote SM behavior among adults with stroke. Furthermore, they can assist hospitals in transitioning care to the community by emphasizing holistic nursing practices that educate about stroke prevention knowledge, encourage family support, and provide stress management strategies to enhance the SM abilities of adults with stroke.

Fertility issues in women of childbearing age with spondyloarthritis.

The topic of fertility in women with spondyloarthritis (SpA) has been scarcely investigated to date. Recent systematic reviews and registry studies have brought renewed attention to the plight of women of childbearing age with rheumatic diseases, in particular SpA. Fertility may be impacted by physical impairment, hormonal imbalances and psychological distress. Several studies observed a reduction in anti-Müllerian hormone in women with SpA, reflecting a reduced ovarian reserve (OR). Furthermore, disease activity and the use of certain therapies can alter fertility, and this is reflected in a prolonged time-to-pregnancy (TTP), a validated outcome measure that can evaluate the status of subfertility. The employment of glucocorticoids or non-steroidal anti-inflammatory drugs has also been linked to reduced fertility, whereas the use of biologics, especially tumour necrosis factor inhibitors (TNFi), is not associated with a prolonged TTP. In all women of childbearing age with rheumatic diseases, preconception counselling is paramount, and a referral to a reproductive specialist should be considered in the presence of multiple factors that may influence fertility. A comprehensive evaluation involving a multidisciplinary team of rheumatologists, gynaecologists, and often psychologists is warranted. In this narrative review, we collected the currently available literature focusing on fertility issues in women affected by SpA, providing data on fertility outcomes, hormonal imbalance, and therapeutic concerns.

Deciphering dynamic interactions among multidimensional psychological motivations, academic performance, and sociocultural adjustment: The critical influence of excessive WeChat use.

As the preeminent mobile social media platform in Mainland China, WeChat's meteoric expansion has revolutionized the dynamics of interpersonal communication and the modalities of mutual interaction among individuals. Despite the escalating significance of mobile social media in the cross-cultural adaptation of international students, existing scholarly works have largely neglected the underlying relationship between psychological motivations, excessive WeChat use, academic performance, and sociocultural adaptation of these students. Anchored in uses and gratifications theory and cross-cultural adaptation paradigm, the primary objectives of this study are to devise a theoretical model and to scrutinize differential psychological motivations propelling international students' WeChat usage, its association with excessive WeChat use, and impacts on academic performance and sociocultural adjustment. The proposed model undergoes meticulous evaluation through data amassed online from 598 Chinese international students studying in Germany. Sequential analytical techniques, especially Confirmatory Factor Analysis and Structural Equation Modeling, were employed to elucidate the dynamic interplay among key variables. The final results validate the path effect suggesting that both hedonic and social motivations are positive predictors of excessive WeChat use. Moreover, excessive WeChat use is negatively correlated with academic performance and sociocultural adjustment. However, utilitarian motivation is not significantly related to excessive WeChat use. By demystifying the driving factors and consequences of excessive WeChat use, these findings not only accentuate the pivotal role of mobile social media in the cross-cultural adaptation of international students but also enrich the theoretical landscape and enhance the strategic approaches for educators and academic institutions.

Determining multidimensional influences of network heterogeneity on university students' psychological and academic well-being: The mediating role of social network exhaustion.

Mobile social media has become indispensable to university students' communication with various socio-demographic populations, exposing them to diverse social networks and augmenting their network heterogeneity. Although the psychological ramifications of network heterogeneity have been extensively examined, its correlated academic outcomes remain inconclusive. The current study formulated an integrated theoretical research model based on the stressor-stress-outcome framework to investigate the influence of factors associated with network heterogeneity (specifically, privacy invasion, social comparison, self-presentation, and excessive WeChat use) on social media exhaustion, psychological well-being, and academic well-being among university students. Furthermore, the research examined the mediating effect of social network exhaustion among network heterogeneity, psychological well-being, and academic well-being. A cross-sectional survey of 1128 WeChat users revealed that social comparison and excessive WeChat use had positive associations with social network exhaustion, while privacy invasion and self-presentation were negatively correlated with social network exhaustion. Additionally, social network exhaustion was negatively correlated with psychological well-being and academic well-being. Furthermore, social network exhaustion mediated the influences of network heterogeneity on psychological well-being and academic well-being. These obtained results could contribute to a more nuanced understanding of the underlying causes of social network exhaustion and the multifaceted effects of network heterogeneity. These insights may prove valuable for practitioners to enhance university students' psychological states and academic performance in the contemporary mobile media-saturated environment.

Multidimensional impact of sport types on the psychological well-being of student athletes: A multivariate investigation.

The correlation between sports participation and psychological well-being is well-documented, revealing a complex interplay influenced by competition level and cultural context. This is particularly relevant in Korea, where the university sports culture significantly impacts student life. This study evaluates how competitive versus non-competitive sports affect Korean university students' psychological well-being using a quantitative approach with SmartPLS 4 for multi-group analysis. Findings reveal that competitive sports significantly enhance mental toughness and stress management through structured coping mechanisms and robust social support, improving coping strategy effectiveness by 34 % compared to non-competitive sports. Conversely, participants in non-competitive sports experience greater general well-being with a 40 % higher use of informal support. These insights suggest that university sports programs could benefit from targeted interventions incorporating specific coping strategies and social support frameworks tailored to the competitive context. This research underscores the need for precise stress management techniques and resilience-building exercises in sports curricula to optimize psychological well-being across different sports environments in Korean universities.

Mapping global prevalence of menopausal symptoms among middle-aged women: a systematic review and meta-analysis.

BACKGROUND: Women at middle age are puzzled by a series of menopausal disturbances, can be distressing and considerably affect the personal, social and work lives. We aim to estimate the global prevalence of nineteen menopausal symptoms among middle-aged women by performing a systematic review and meta-analysis. METHODS: Comprehensive search was performed in multiple databases from January, 2000 to March, 2023 for relevant studies. Random-effect model with double-arcsine transformation was used for data analysis. RESULTS: A total of 321 studies comprised of 482,067 middle-aged women were included for further analysis. We found varied prevalence of menopausal symptoms, with the highest prevalence of joint and muscular discomfort (65.43%, 95% CI 62.51-68.29) and lowest of formication (20.5%, 95% CI 13.44-28.60). Notably, South America shared dramatically high prevalence in a sort of menopausal symptoms including depression and urogenital symptoms. Besides, countries with high incomes (49.72%) had a significantly lower prevalence of hot flashes than those with low (65.93%), lower-middle (54.17%), and upper-middle (54.72%, p < 0.01), while personal factors, such as menopausal stage, had an influence on most menopausal symptoms, particularly in vaginal dryness. Prevalence of vagina dryness in postmenopausal women (44.81%) was 2-fold higher than in premenopausal women (21.16%, p < 0.01). Furthermore, a remarkable distinction was observed between body mass index (BMI) and prevalence of sleep problems, depression, anxiety and urinary problems. CONCLUSION: The prevalence of menopausal symptoms affected by both social and personal factors which calls for attention from general public.

Associations between domains of sedentary behavior, well-being, and quality of life - a cross-sectional study.

The importance of reducing sedentary behavior (SB) in the prevention of mortality and chronic and mental diseases is scientifically well grounded, but SB can be accumulated in diverse domains of life, such as leisure-time SB, transport between home/work/school when sitting (transport-related SB), or in occupational settings such as working or studying (occupational SB), and the associations for each domain of SB with well-being measures and quality of life are still underexplored from a positive perspective. Through a cross-sectional investigation, we collected data from 584 participants who completed a questionnaire throughout November 2021 and with Spearman correlation test, analysed the associations between SB in three different domains with psychological well-being, satisfaction with life, and quality of life. Our results indicated that after adjustment for physical activity, sex, body mass index, smoking history, chronic disease status, financial perception, quality/duration of sleep and university group, in younger adults (18 to 24 years old), leisure-time SB was negatively related to psychological well-being (rho = -0.255; p = 0.008), and in adults (25 to 64 years old), occupational SB was negatively related to satisfaction with life (rho = -0.257; p < .001) and the mental component of quality of life (rho = -0.163; p = 0.027). Our findings highlight the idea that not all SB is built the same and that future strategies to reduce SB from people's lives must target specific domains of SB according to the age group when aiming to improve well-being and quality of life.

Emerging paradigms: unmasking the role of oxidative stress in HPV-induced carcinogenesis.

The contribution of the human papillomavirus (HPV) to cancer is significant but not exclusive, as carcinogenesis involves complex mechanisms, notably oxidative stress. Oxidative stress and HPV can independently cause genome instability and DNA damage, contributing to tumorigenesis. Oxidative stress-induced DNA damage, especially double-strand breaks, aids in the integration of HPV into the host genome and promotes the overexpression of two viral proteins, E6 and E7. Lifestyle factors, including diet, smoking, alcohol, and psychological stress, along with genetic and epigenetic modifications, and viral oncoproteins may influence oxidative stress, impacting the progression of HPV-related cancers. This review highlights various mechanisms in oxidative-induced HPV-mediated carcinogenesis, including altered mitochondrial morphology and function leading to elevated ROS levels, modulation of antioxidant enzymes like Superoxide Dismutase (SOD), Glutathione (GSH), and Glutathione Peroxidase (GPx), induction of chronic inflammatory environments, and activation of specific cell signaling pathways like the Phosphoinositide 3-kinase, Protein kinase B, Mammalian target of rapamycin (PI3K/AKT/mTOR) and the Extracellular signal-regulated kinase (ERK) signaling pathway. The study highlights the significance of comprehending and controlling oxidative stress in preventing and treating cancer. We suggested that incorporating dietary antioxidants and targeting cancer cells through mechanisms involving ROS could be potential interventions to mitigate the impact of oxidative stress on HPV-related malignancies.

Pets at work: integrating pet-friendly initiatives into human resources for enhanced workplace harmony.

AIMS: The representation of companion animals, or pets, has been changing recently. Research concerning how pets influence employees' work-related well-being has also started to take its first steps. This research aimed to analyze (1) how managers perceive pet-friendly practices and their main effects at work, and (2) the impact of such practices on employees' well-being and work engagement. Relying on the social exchange perspective and the self-determination theory it was hypothesized that pet-friendly practices would positively influence employees' well-being and work engagement by satisfying their three basic needs (autonomy, competence, and relatedness). METHODOLOGY: Two studies with mixed methods were conducted. The first and exploratory study resorted to semi-structured interviews with six managers. The second was a two-wave study conducted with a large sample of workers (N = 379). RESULTS: The first study highlighted the primary advantages and disadvantages of pet-friendly practices, along with the various obstacles and limitations, and proposed managerial strategies to overcome them. Managers generally expressed interest and enthusiasm about the topic but also pointed out challenges in implementing a pet-friendly strategy due to the limited number of empirical studies demonstrating its benefits. The second study's findings indicated that pet-friendly practices positively impacted employees' work engagement and well-being by fulfilling their needs for competence, autonomy, and relatedness. ORIGINALITY: Overall, Portugal is seen as having a conservative culture, which slows the dissemination and implementation of these measures. To overcome these challenges, several managerial recommendations have been proposed. Raising awareness and fostering discussion on the topic are crucial steps toward integrating pet-friendly policies into human resources management.

Mobile App-Based Mindfulness Intervention for Addressing Psychological Distress Among Survivors of Hospitalization for COVID-19 Infection.

BACKGROUND: Psychological distress symptoms are present and persistent among many patients who survive a critical illness like COVID-19. RESEARCH QUESTION: Could a self-directed mobile app-delivered mindfulness intervention be feasibly and rapidly implemented within a clinical trials network to reduce distress symptoms? STUDY DESIGN AND METHODS: A randomized clinical trial was conducted between January 2021 and May 2022 at 29 US sites and included survivors of hospitalization due to COVID-19-related illness with elevated symptoms of depression at discharge. Participants were randomized to intervention or usual care control. The intervention consisted of four themed weeks of daily audio, video, and text content. All study procedures were virtual. The primary outcome was depression symptoms assessed with the Patient Health Questionnaire 9 at 3 months. Secondary outcomes included anxiety (Generalized Anxiety Disorder 7-item scale), quality of life (EQ-5D), and adherence. We used general linear models to estimate treatment arm differences in outcomes over time. RESULTS: Among 56 randomized participants (mean age ± SD, 51.0 ± 13.2 years; 38 female [67.9%]; 14 Black participants [25%]), 45 (intervention: n = 23 [79%]; control: n = 22 [81%]) were retained at 6 months. There was no difference in mean improvement between intervention and control participants at 3 months in Patient Health Questionnaire 9 (-0.5 vs 0.1), Generalized Anxiety Disorder 7-item scale (-0.3 vs 0.1), or EQ-5D (-0.03 vs 0.02) scores, respectively; 6-month results were similar. Only 15 participants (51.7%) initiated the intervention, whereas the mean number ± SD of the 56 prescribed intervention activities completed was 12.0 ± 15.2. Regulatory approvals delayed trial initiation by nearly a year. INTERPRETATION: Among survivors of COVID-19 hospitalization with elevated psychological distress symptoms, a self-directed mobile app-based mindfulness intervention had poor adherence. Future psychological distress interventions mobilized at broad scale should focus efforts on patient engagement and regulatory simplification to enhance success.

Does a single session of transcranial direct current stimulation enhance both physical and psychological performance in national- or international-level athletes? A systematic review.

Some studies showed that a single session of transcranial direct current stimulation (tDCS) has the potential of modulating motor performance in healthy and athletes. To our knowledge, previously published systematic reviews have neither comprehensively investigated the effects of tDCS on athletic performance in both physical and psychological parameters nor investigated the effects of tDCS on high-level athletes. We examined all available research testing a single session of tDCS on strength, endurance, sport-specific performance, emotional states and cognitive performance for better application in competition and pre-competition trainings of national- or international-level athletes. A systematic search was conducted in PubMed, Web of Science, EBSCO, Embase, and Scopus up until to June 2023. Studies were eligible when participants had sports experience at a minimum of state and national level competitions, underwent a single session of tDCS without additional interventions, and received either sham tDCS or no interventions in the control groups. A total of 20 experimental studies (224 participants) were included from 18 articles. The results showed that a single tDCS session improved both physical and psychological parameters in 12 out of the 18 studies. Of these, six refer to the application of tDCS on the motor system (motor cortex, premotor cortex, cerebellum), five on dorsolateral prefrontal cortex and two on temporal cortex. The most sensitive to tDCS are strength, endurance, and emotional states, improved in 67%, 75%, and 75% of studies, respectively. Less than half of the studies showed improvement in sport-specific tasks (40%) and cognitive performance (33%). We suggest that tDCS is an effective tool that can be applied to competition and pre-competition training to improve athletic performance in national- or international-level athletes. Further research would explore various parameters (type of sports, brain regions, stimulation protocol, athlete level, and test tasks) and neural mechanistic studies in improving efficacy of tDCS interventions.
