The health of young people is crucial for the future and development of a nation. It is the collective responsibility and imperative mission of society to ensure the holistic well-being, both physically and mentally, of young individuals. Therefore, it is essential to thoroughly comprehend the factors that influence their health in order to expedite the exploration of effective solutions. The objective of this study is to comprehend the mechanisms that underlie the correlation between physical exercise behavior and psychological resilience among teenagers, while also examining the mediating role played by social sensitivity and need to belong. So put forward the hypothesis: (1) physical exercise behavior can positively predict the psychological resilience. (2) Social sensitivity and need to belong plays a mediating role between physical exercise behavior and psychological resilience. (3) Social sensitivity and need to belong plays a chain mediating role between physical exercise behavior and psychological resilience. Using the cluster sampling method, a total of 1106 students (with an average age of 15.7 and a standard deviation of 0.598) who met the requirements were surveyed from Shandong Province in China. Standard scales were utilized to assess Physical Exercise Behavior, Psychological Resilience, Social Sensitivity, and Need to Belong. For data analysis, Pearson's correlation analysis and bias-corrected percentile Bootstrap method were sequentially conducted. (1) The present study did not find any significant methodological bias, and the observed correlations between physical exercise behavior, psychological resilience, social sensitivity, and need to belong were all statistically significant; (2) Based on the self-determination theory, this study elucidates the relationship between physical exercise behavior and psychological resilience among teenagers. The findings indicate that physical exercise behavior positively predicts the need to belong and psychological resilience, while negatively predicting social sensitivity. Similarly, social sensitivity negatively predicts the need to belong and psychological resilience. Moreover, the need to belong directly and positively predicts psychological resilience. Importantly, all hypotheses proposed in this paper were empirically supported. (3) The indirect effect of the path mediated by social sensitivity is 0.009, while the indirect effect of the path mediated by need to belong is 0.033. Additionally, the combined indirect effect of both social sensitivity and need to belong as mediating variables is 0.014. (4) The cumulative sum of all these indirect effects amounts to 0.056. Based on the self-determination theory, we propose a chain mediation model, specially, physical exercise behavior can significantly positively predict psychological resilience, among which, social sensitivity and need to belong play a significant mediating role between Physical exercise behavior and psychological resilience. In addition, the adoption of good physical exercise behavior can enhance the psychological resilience of adolescents by diminishing social sensitivity and augmenting the need to belong.

INTRODUCTION Youth smoking is a serious public health problem. Nevertheless, a rigorous tobacco-free environment within schools, combined with exemplary tobacco control behavior among school personnel can effectively contribute to reducing adolescent smoking. This study compared the tobacco control environment in Shanghai secondary schools in 2017 and 2021, and explored how the tobacco control environment influenced the tobacco control behaviors of school personnel. METHODS Two cross-sectional studies were conducted from October to December 2017 and October to December 2021, using stratified cluster random sampling method, and 2403 and 1761 valid questionnaires were collected, respectively. The chi-squared test was used to test the differences between categorical variables. Binary logistic regression was conducted using survey data from 2021 to explore the influencing factors of staff's tobacco control behaviors. RESULTS Compared with 2017, the percentages of staff members who were current smokers, had smoked on campus in the past year and were exposed to secondhand smoke (SHS) on campus in the past 7 days in 2021 decreased by 2.95%, 2.30% and 8.91%, respectively. However, the proportion of personnel who knew the school had organized tobacco control education decreased. Furthermore, school personnel who had received tobacco control education and agreed the school should strictly prohibit students from smoking (AOR=1.64; 95% CI: 1.25--2.15) were more likely to inform about the harm of tobacco to students. Those who had participated in tobacco control education activities or tobacco control trainings (AOR=1.87; 95% CI: 1.30--2.69) and believed that the school did not strictly prohibit either students (AOR=0.30; 95% CI: 0.22--0.41) or personnel (AOR=0.46; 95% CI: 0.36--0.59) from smoking were more inclined to stop students from smoking. CONCLUSIONS Compared with 2017, the rates of smoking and secondhand smoke exposure among school personnel decreased in 2021, but some schools still lacked comprehensive education on tobacco control behaviors for the staff. Enhancing the health literacy and strengthening tobacco control education among staff were effective strategies to encouraging their active adoption of tobacco control behaviors.

Adolescent suicide has become an increasingly serious social problem in China. Bullying victimization was found to be an influential factor of suicidal tendency, but less attention has been paid to the internal mechanisms of the relationship. This paper examined the relationship between adolescents' bullying victimization and suicidal tendency, and the mediating effects of internalizing problems and non-suicidal self-injury (NSSI). Generalized Structural Equation Model was employed to a sample of 3,575 Chinese secondary school students. Bullying victimization has a direct positive impact on adolescents' suicidal tendency, but also has an indirect impact on suicidal tendency through three paths: the independent mediating role of internalizing problems and NSSI, and the chain mediating role of internalizing problems and NSSI. The results suggested that students who are bullied tend to have a higher risk of suicidal tendency, and internalizing problems and NSSI are usually the prelude to suicidal behaviors.

Purpose: To understand whether a culture-based multicomponent cognitive training program is feasible and tolerable for persons with dementia (PWD) in day care centers in Taiwan, and to examine the effectiveness of a 16-week program in preventing declines in cognitive function and self-care, as well as the development of depressed mood and behavioral problems. Method: This study was a 4-month cluster randomized controlled trial. PWD (N = 56) who met sample selection criteria were recruited from five day care centers and assigned to the experimental or comparison group. Participants in the experimental group received a series of culture-based multicomponent cognitive training activities via research assistants and day care center caregivers for 16 weeks. Participants in the comparison group received usual daily activities. Time attending activities and degree of participation were used as criteria for determining feasibility and tolerability of the program. Results: Results confirmed the feasibility of culture-based multicomponent cognitive training activities if the activities were guided by caregivers. Results also showed participants in the experimental group had statistically significant improvements in cognitive function. Activities of daily living performance, depressed mood, and behavioral problems showed non-significant improvements. Conclusion: The current study suggests that this program can assist PWD in preventing declines in self-care and the development of behavioral and psychological problems, and improve their cognitive function. Further research with a larger sample size and staff training should be considered to test the effectiveness of this program.

Background: Burnout is very important to nurses' physical and mental health and career development. Current approaches to assessing nurse burnout tend to use a total score modeling paradigm to explore the impact of external factors on burnout. The purpose of this study is to delve into the item-level relationship between nurse burnout and its influencing factors at both the social and psychological levels using a network analysis approach. Methods: This study was conducted in June 2023 and 1,005 nurses from 4 hospitals out of 8 tertiary care hospitals in Harbin were selected to participate in this study using whole cluster sampling method. Measurements included a general demographic questionnaire, Trait coping styles questionnaire, Organizational commitment questionnaire, Work-family conflict scale, Transformational leadership questionnaire, and Maslach Burnout Inventory-General Survey. Results: Our results suggest that "C1 Time-Based work interference with family" showed the strongest centrality and bridging in the overall network. This finding underscores its centrality to burnout. Other strongest bridge symptoms included "E2 Reduced personal accomplishment" and "A1 Positive coping styles" indicating their strongest connections to other clusters. Conclusions: Nurse administrators should be encouraged to pay more attention to nurses' work situations and family distress, and to help nurses in a flexible way. [ABSTRACT FROM AUTHOR]

Background: Healthcare-associated infections (HAIs) are important indicators of healthcare quality. The aseptic non touch technique (ANTT), a standardised aseptic technique, is a crucial preventative measure against HAIs. However, there is insufficient evidence currently available regarding ANTT awareness and proficiency among nurses. This study aimed to investigate the status of ANTT proficiency in a cohort of nurses and analyse the associated risk factors, with the ultimate goal of providing a reference for promoting the application of ANTT in clinical practice. Methods: The study population was sampled from nurses working in a tertiary hospital in Zhejiang Province, China, in January 2024. A cross-sectional survey was conducted using a self-designed questionnaire to assess ANTT knowledge. Multivariate linear regression analysis was used to analyse the risk factors influencing ANTT knowledge in nurses. Results: A total of 458 nurses were included in this study. The cohort had an overall score of 49.7% correct responses on the ANTT knowledge questionnaire, with a mean score of 12.4 ± 2.4 out of 25, and 30.1% of the nurses felt that they did not need training related to ANTT. Multivariate linear regression analysis indicated that professional title, educational level, and the need for ANTT training were independently associated with ANTT knowledge in nurses. Nurses with Master's degrees and associated chief nurses were observed to have higher levels of ANTT knowledge compared to the rest. Conclusions: ANTT knowledge is insufficient among nurses in China, and its importance is not widely recognised. Continuous efforts are required to strengthen this knowledge. Constructing sustained, multiform, and stratified training programmes may represent an effective method to strengthen ANTT knowledge among nurses and promote its clinical use. [ABSTRACT FROM AUTHOR]

Background: Stroke is one of the primary causes of disability in China and around the world, having an impact on the health and well-being of stroke patients. The importance of spiritual needs for stroke patients has always been a controversial topic internationally, partly because related research was mostly qualitative and may not directly reflect the degree of spiritual needs. In addition, most studies focus on the same cultural background, there is a lack of research that delves into the nuances of Chinese culture and background. The goal of this study is to evaluate the level of spiritual needs and influencing factors in Chinese stroke patients and to explore the mediating role and pathways of these variables on spiritual needs. Methods: From August 2022 to January 2023, we conducted a cross-sectional questionnaire survey of 422 stroke patients in the affiliated hospitals of Hunan University of Chinese Medicine in Changsha Province by cluster sampling. We measured the patient's spiritual needs, quality of life, anxiety and depression levels, and family support using the Spiritual Needs Questionnaire (SPNQ), the MOS36 item Short Form Health Survey (SF-36), the Hospital Anxiety and Depression Scale (HADS), and the Family Support Self Rating Scale (PSS-Fa). We used the General Information Questionnaire to gain insight into the sociodemographic characteristics of the patients. Nonparametric tests and multiple linear regression models were used to analyze the independent relationship between spiritual needs and quality of life, anxiety, depression, and family support. The mediation model in AMOS 24.0 software was used to analyze the mediating role among the five variables. Results: The score of spiritual needs of people with stroke included in this study was 37 points [IQR 33 to 40)]. The influencing factors of spiritual needs included primary economic sources for disease-related expenditures (p = 0.044), number of stroke occurrences (p = 0.001), duration of illness (p = 0.023), activities of daily living (p = 0.006), depression scores(p = 0.034), and family support scores(p = 0.008). Anxiety (β = 0.347, p = 0.004), depression (β = 0.368, p = 0.005), and family support (β = 0.167, p = 0.023) had directly or indirectly affected the spiritual needs of people with stroke. Quality of life (β=-0.202, p = 0.017) had a direct effect on spiritual needs. Conclusions: The spiritual needs of people with stroke were at an intermediate level. Our findings highlight that the SPNQ score is associated with anxiety, depression, quality of life, and family support. Therefore, nurses should identify the spiritual needs of patients and provide them with effective and comprehensive spiritual care by reducing negative emotions and enhancing social support, promoting the development and progress of spiritual care in China. This study offers a theoretical basis for the spiritual care of clinical people with stroke and constructing a stroke spiritual care model. [ABSTRACT FROM AUTHOR]

Background: Studies has suggested that receiving social support improves the professional identity of health professional students. According to the two-way social support theory, social support includes receiving social support and giving social support. However, the effect of the two-way social support on health professional students' professional identity has not been clarified yet. Methods: To explore the mechanism of how two-way social support affects health professional students' professional identity, an observational, cross-sectional study was conducted among a convenience and cluster sample of 1449 health professional students from two medical schools in western China. Measures included a short version of the two-way social support scale, a health professional students' professional identity questionnaire, an achievement motivation scale, and a meaning in life scale. (Data were analyzed by use of SPSS26.0 software, Amos 28.0 software, and PROCESSv4.0 plug-in.). Results: Receiving social support, giving social support, achievement motivation, meaning in life, and professional identity were positively correlated with each other. Receiving and giving social support not only directly predicted health professional students' professional identity, but also indirectly predicted health professional students' professional identity through the mediating roles of achievement motivation and meaning in life, and the chain mediating roles of achievement motivation and meaning in life, respectively. The effectiveness of predicting health professional students' professional identity varied among different types of two-way social support, which could be depicted as two-way social support > mainly giving social support > mainly receiving social support > low two-way social support. Conclusion: In the medical education, the awareness and ability of health professional students to receive and give social support should be strengthened. More attention should be drawn on the chain mediating effect of achievement motivation and meaning in life between two-way social support and professional identity. The current results shed new light on exploring effective ways of improving health professional students' professional identity, which suggested that more attention should be paid to the positive effects of mainly giving social support and two-way social support rather than only on the effects of receiving social support.

The association between childhood bullying victimization and depression has been well-explored among young adults, but little is known about whether this relationship persists into later life stages, specifically during middle-aged and older phases. Moreover, the intricate mechanisms underpinning this association and the potential existence of gender differences within this context remain inadequately elucidated. To address this gap in knowledge, this study aims to investigate the association between childhood bullying victimization and depression in later life, with a focus on exploring the mediating role of social isolation and the moderating roles of gender. A nationally representative sample of 5,070 individuals (mean age = 61.02, SD = 9.48; male = 55%) was drawn from the China Health and Retirement Longitudinal Study. By employing the bootstrapping analysis method, the mediating role of social isolation was examined, and the moderating role of gender was tested through the generation of interaction items. The results reveal a significant association between childhood bullying victimization and severe depression in later life. Additionally, social isolation plays a mediating role in this association between childhood bullying victimization and social isolation, and the association between social isolation and depression, as well as the relationship between social isolation and depression, are both moderated by gender, presenting stronger effects for female groups than for male groups. However, no moderating role of gender is found in terms of the direct association between childhood bullying victimization and depression. These findings highlight the fact that childhood bullying is not only a problem in the immediate term but also a concern that affects individuals across entire life course. This study has implications for healthcare in proactively investigating, diagnosing, and treating depression by inquiring about childhood bullying victimization experiences. Furthermore, intervention policies that aim to reduce social isolation may be particularly beneficial in mitigating the negative associations, especially for female individuals.

The purpose of the current study was to examine the serial mediating effects of rejection sensitivity and social withdrawal on parental psychological control and attitudes toward seeking professional psychological help among senior high school students. In November 2022, 648 students completed a self-report questionnaire. The parental psychological control scale, senior high school students' rejection sensitivity scale, social withdrawal scale, and attitudes toward seeking professional psychological help scale were used for measurement. Correlation analysis showed parental psychological control and rejection sensitivity were positively correlated with social withdrawal (r = 0.387, 0.466, 0.495, all p < 0.001). Parental psychological control and rejection sensitivity were significantly negatively correlated with social withdrawal and attitudes toward seeking professional psychological help (r = −0.325, −0.324, −0.397, all p < 0.001). Mediating effect analysis indicated that parental psychological control had a significant direct effect on attitude toward seeking professional psychological help, and rejection sensitivity and social withdrawal had significant serial mediating effects among parental psychological control and attitudes toward seeking professional psychological help in senior high school students. These aspects warrant attention as they play significant roles in influencing students' willingness to seek psychological assistance.

Objective: To understand the prevalence of home-related anxiety among adolescent athletes during the novel coronavirus pandemic and to ascertain the factors influencing this anxiety. Methods: We employed cluster sampling to select 1150 adolescent athletes (aged 8–18 years) from six sports training schools in Yantai City, Shandong Province. Mental health status was assessed and recorded. Chi-square tests and multivariable logistic regression were used to analyze the factors contributing to athletes' anxiety. Results: The survey revealed a COVID-19 infection rate of 38.23% (437 individuals) with an anxiety score of 40.98 ± 8.20 and an anxiety detection rate of 11.29% (129 individuals) during the COVID-19 epidemic. Female athletes exhibited a higher anxiety rate of 14.40% compared to 8.40% in male athletes. Multivariate analysis identified female gender as a risk factor for anxiety (OR = 1.64), while participation in aquatics emerged as a protective factor (OR = 0.24, 95% CI: 1.08–2.48). Professional training duration exceeding three years increased anxiety risk (OR = 3.05, 95% CI: 1.67–5.58), as did not seeking help during difficulties (OR = 2.59, 95% CI: 1.33–5.01). Interestingly, parental care was linked to increased anxiety risk (OR = 2.44, 95% CI 1.34–4.44), while care from friends was protective (OR = 0.60, 95% CI: 0.36–1.01), which was possibly due to the pressure associated with parental expectations. Conclusions: Adolescent athletes, particularly females and those with extended training durations, exhibit a heightened susceptibility to anxiety. This study also highlights that athletes who proactively seek assistance during challenging situations tend to experience lower anxiety levels. Additionally, a lack of COVID-19 infection and the involvement of concerned parents contribute to reduced anxiety among these young athletes. [ABSTRACT FROM AUTHOR]

China's northern Hulun Lake is a significant body of water internationally. The issue of eutrophication has gained prominence in recent years. The achievement of precise chlorophyll-a (Chl-a) monitoring is crucial for safeguarding Hulun Lake's ecosystem. The machine learning-based remote sensing inversion method has been shown to be effective in capturing the intricate relationship between independent and dependent variables; however, it lacks a priori knowledge and is limited by the quality of remote sensing data sources. The relationship between independent and dependent variables can be more accurately simulated with the use of suitable auxiliary variables. Therefore, three machine learning models—random forest (RF), adaptive boosting (AdaBoost), and extreme gradient boosting (XGBoost)—were established in this study using meteorological observation parameters as auxiliary variables combined with Sentinel-2 satellite image remote sensing band combinations as independent variables and measured Chl-a data as dependent variables. The estimation effects before and after the fusion of meteorological ground observation data were compared, and the best model was used to estimate the spatial–temporal variation trend of Chl-a in the regional water body. The results show that (1) the addition of meteorological parameters as auxiliary variables improved the precision of the three machine models; the decision coefficient (R2) rose by 7.25%, 5.71%, and 7.20%, respectively, to 0.76, 0.66, and 0.73. (2) The concentration of Chl-a in the lake region was projected from June to October 2019 to October 2021 using the RF optimal estimating model of meteorological fusion. The northeast, southwest, and south of the lake were where the comparatively high concentration values of Chl-a were located, whereas the lake's center had a generally low concentration of the substance. Chromatically, Chl-a typically peaked in August after initially increasing and then declining. (3) The three rivers that feed into the river have varying levels of water pollution, with chemical oxygen demand (COD) and total nitrogen (TN) pollution being the most severe. This is what primarily caused the higher levels of Chl-a in the northeast, southwest, and south. This study is crucial for the preservation and restoration of Hulun Lake's natural ecosystem and offers some technical support for the monitoring of the lake's concentration of Chl-a.

Background: Social consensus in the nursing industry is that the job is accompanied by dirtiness. It is generally accepted that negative cognition about a career is an important determinant in reducing nursing students' professional commitment. However, the impact of nursing students' perceived work dirtiness on professional commitment and its mechanism remains unclear. This study aimed to analyze the association between perceived work dirtiness and professional commitment and to examine the mediating role of career adaptability and the moderating role of social support among nursing students in mainland China. Methods: A cross-sectional online study was conducted among 341 nursing students from three medical universities in Henan, China. The participants' perceived work dirtiness, career adaptability, professional commitment, and social support were obtained. SPSS 26.0 and Amos 23.0 software were used for the statistical analysis. Results: Perceived work dirtiness was negatively related to career adaptability and professional commitment (P < 0.001). Career adaptability played a partial mediating role (β= -0.177, P < 0.001) in the relationship between perceived work dirtiness and professional commitment. Social support played a moderating role (β = 0.134, P < 0.01) in the relationship between perceived work dirtiness and career adaptability. Moreover, social support moderates the mediating role of career adaptability. Conclusions: Nursing students' perceived work dirtiness is an important factor in reducing professional commitment. Therefore, nursing educators must enhance courses focusing on professional qualities, providing avenues for nursing students to access social support. This proactive approach aims to mitigate the adverse impact of perceived work dirtiness on professional commitment among nursing students. [ABSTRACT FROM AUTHOR]

Background: The shortage of nurses has been a global human resources problem. A good professional growth environment is essential to developing potential nursing students and attracting nurses to join, and it has great significance in reducing nurse turnover. However, nurses' comprehensive perceptions of professional growth have not yet been examined. Methods: A cluster sampling method was used to conduct a professional growth questionnaire survey on young nursing talents from a large Chinese public tertiary A hospital in March 2022. Results: The score of professional growth among 243 young nursing talents was 57.92 ± 9.607, with a scoring rate of 77.23%. The scores for dimensions of professional growth, from lowest to highest, were rehabilitation growth, promotion speed, professional goal progress, and professional ability development. Attitudes towards participating in training, service as the quality manager or clinical teacher, self-efficacy, professional title, work-family support, education, and organizational commitment of young nursing talents were significantly associated with professional growth. Conclusion: The professional growth of young nursing talents was at a moderate level and needed to be strengthened. Nursing leaders and managers are expected to develop management practices to enhance young nursing talents' professional growth in combination with the related factors. [ABSTRACT FROM AUTHOR]

Aims and Objectives: (i) To estimate the national incidence of unplanned removal of peripherally inserted central catheters (PICCs) in China. (ii) To explore the associated risk factors to provide evidence for the prevention. Design: A multi‐centre prospective cohort study. Methods: A representative sample of 3222 Chinese adult patients with successful PICC insertion was recruited for the PICC Safety Management Research (PATH) using a two‐stage cluster sampling method from December 2020 to June 2022. Sixty hospitals from seven Chinese provinces representing all geographical regions were selected. Demographic information and PICC characteristics were collected using a standard online case report form. Risk factors for the unplanned removal of PICCs were assessed using a cause‐specific hazard model and verified using a sub‐distribution hazard model. STROBE guidelines were followed in reporting this study. Results: Three thousand one hundred and sixty‐six patients were included in the final analysis with a mean age of 59 years and a total of 344,247 catheter days. The incidence of unplanned removal was 10.04%. Female, with thrombosis history, PICC insertion due to infusion failure, valved catheter and double‐lumen catheter were risk factors, whereas longer insertion and exposure length were protective factors in the cause‐specific hazard model. Higher BMI became an independent risk factor in the sub‐distribution hazard model. Conclusions: Unplanned removal of PICCs is a serious clinical challenge in China. Our findings call for prevention strategies targeting the identified risk factors. Relevance to Clinical Practice: Our study characterised the epidemiology of unplanned removal of PICCs among Chinese adult inpatients, highlighting the need for prevention among this population and providing a basis for the formulation of relevant prevention strategies. Patient or Public Contribution: Patients contributed through sharing their information required for the case report form. Healthcare professionals who provide direct care to the patient at each medical centre contributed by completing the online case report form. [ABSTRACT FROM AUTHOR]

Chinese government promoted a family physician contract service system in order to establish a tiered healthcare system in June 2016, but there was little evidence to assess the policy performance. This study aimed to examine the association of family physician contract services with the healthcare utilization of community residents in urban China. A cross-sectional face-to-face survey was conducted from July to September, 2019, in four advanced and exemplary cities for family physician contract services in China. A multistage cluster random sampling method was adopted to recruit residents aged 18 and above, and a total of 1508 participants were included in this study. The count model and logit regression were adopted to examine the associations between family physician contract service and healthcare utilization, and the potential bias was addressed using the propensity score matching (PSM) method. There was an increase in number of monthly primary care visits and annual referrals for contracted residents compared to noncontracted residents. Participants who had contracted with a family physician were more likely to choose a primary healthcare facility after illness than those who had not. However, no significant change was found in the number of annual hospital admissions between contracted and noncontracted residents. Family physician contract services may effectively strengthen the use of primary care facilities by community residents and promote the formation of a tiered healthcare system in China.

Background: In public health emergencies, nurses are vulnerable to adverse reactions, especially job burnout. It is critical to identify nurses at risk of burnout early and implement interventions as early as possible. Methods: A cross-sectional survey of the hospitals in Xiangyang City was conducted in January, 2023 using stratified cluster sampling. Anonymized data were collected from 1584 working nurses. The Impact of Events Scale-Revised (IES-R) and the Chinese version of the Maslach Burnout Inventory-General Survey (MBI-GS) were used to evaluate the post-traumatic stress disorder (PTSD) and burnout of nurses in public health emergencies. Logistic regression analysis was established to screen for risk factors of burnout, and a nomogram was developed to predict the risk of burnout. A calibration curve and the area under the receiver operating characteristic (ROC) curve were used to validate the nomogram internally. Results: This study showed that only 3.7% of nurses were completely free of PTSD during a public health emergency. We found that PTSD varied by age, marital status, procreation status, length of service, employee status, and whether working in the ICU. The nurses aged 30 ~ 40 years old, single, married without children, non-regular employees, worked for less than three years or worked in the ICU had higher levels of PTSD. Regarding the prevalence of burnout, 27.4%, 48.5%, and 18.6% of nurses had a high level of emotional exhaustion (EE), depersonalization (DP), and diminished personal accomplishment (PA), respectively. There, 31.1% of nurses had more than two types of job burnout. The number of night shifts, the type of hospital, marital status, and the severity of PTSD were all associated with higher rates of exhaustion among nurses. As a graphical representation of the model, a nomogram was created and demonstrated excellent calibration and discrimination in both sets (AUC = 0.787). Conclusions: This study confirmed the PTSD and burnout are common problems for in-service nurses during public health emergencies and screened out the high-risk groups of job burnout. It is necessary to pay more attention nurses who are single and working in general hospitals with many night shifts, especially nurses with severe PTSD. Hospitals can set up nurses' personal health records to give timely warnings to nurses with health problems, and carry out support interventions to relieve occupational stress. [ABSTRACT FROM AUTHOR]
