Objective: To understand the occupational stress and mental health status of hospital infection prevention and control practitioner (HIPCPs) in medical institutions, and analyze their main influencing factors. Methods: In November 2021, 550 nosocomial infection managers in Tianjin were randomly selected to conduct a questionnaire survey using the Concise Occupational Stress Questionnaire, Depression Screening Scale (PHQ-9) and Self-Rating Anxiety Scale (SAS). 497 valid questionnaires were obtained, and the total recovery efficiency was 90.36%. Single factor analysis and multivariate logistic regression method were used to analyze the main influencing factors of occupational stress and mental health status of psychiatric managers. Results: The detection rate of anxiety and depression among 497 HIPCPs was 22.73% (113/497) and 58.95% (293/497), respectively. Gender and major were the influencing factors of depression ( P =0.000, 0.001). Average working hours>52 hours per week and night shift days>1 days per week were the influencing factors of anxiety ( P =0.035, 0.014). Average working hours>52 h per week, night shift days >1 d per week and different majors were the influencing factors of occupational stress ( P =0.000, 0.025, 0.010). Multivariate logistic regression results showed that the risk of anxiety in those who worked more than 52 hours per week was 1.753 times that of those who worked less than 52 hours per week ( P =0.038), and the risk of depression in women was 3.071 times that of men ( P =0.006) . Conclusion: Working hours are an important influencing factor for occupational stress and anxiety among HIPCPs. In order to reduce the occurrence of occupational stress and mental health problems, it is necessary to strengthen psychological counseling for HIPCPs and balance work and rest.

Objective: To evaluate the quality and item characteristics of the Brief Job Stress Questionnaire (BJSQ) among employees in manufacturing and service industries. Methods: From December 2021 to December 2022, a total of 2077 employees from 4 manufacturing and service enterprises in Beijing were selected by the method of combining purpose sampling and convenience sampling. The Chinese version of BJSQ was used to carry out a survey on occupational stress from 57 items in 4 dimensions including job stress factors, stress response, social support factors and satisfaction. Classical test theory (CTT) was used to analyze the validity and reliability of the questionnaire. The Semejima hierarchical response model in item response theory (IRT) was used to analyze the differentiation a, difficulty coefficient b and information content of each item. Results: Among the 2077 subjects, the age M ( Q (1), Q (3)) was 33 (28, 37) years old, and the working age M ( Q (1), Q (3)) was 4 (2, 8) years. There were 723 (34.8%) people in manufacturing industry and 1354 (65.2%) people in service industry. Eleven common factors were extracted by exploratory factor analysis, with a cumulative variance contribution rate of 62.823%, the variance of the common factors of each entry ranging from 0.451 to 0.865, and the range of factor loading values from 0.413 to 0.825, with 5 items having cross-loadings. The results of the validation factor analysis showed that the model fit indexes of root means square error of approximation was 0.055, comparative fit index was 0.950, Tucker Lewis index was 0.948, and standardized root mean square was 0.066. Content validity results showed that the total scores of the Chinese version of the BJSQ were positively correlated with the scores of the 4 dimensions ( r (s)=0.487-0.936, P <0.05) . The results of the reliability analysis showed that the Cronbach's alpha coefficient for the total questionnaire was 0.945, and the Cronbach's alpha coefficients of job stress factors, stress response and social support factors were 0.775, 0.957, and 0.830, respectively. The Spearman-Brown coefficient for the total questionnaire was 0.866, and for the 3 dimensions, it was 0.572, 0.882 and 0.772. The results of IRT analysis showed that only 1 of the 57 items had a differentiation a-value<0.30, the difficulty coefficient b-value of each item ranged from -12.02 to 11.09, of which 8 items had a difficulty coefficient that was too high, 3 items had a difficulty coefficient that was too low, and 3 items did not meet the requirements, and the average amount of information in each item ranged from 0.022 to 2.566, and there were 47 items with average amount of information>0.088 (5/57) . Conclusion: The Chinese version of BJSQ has good reliability and validity in the typical occupational groups of manufacturing and service industries in China, and most of the items have good performance, but some items still need to be further improved and optimized or deleted.

Objective: To understand the current situation of long working hours exposure of couriers in Zhejiang Province , and to analyze the influence of long working hours exposure levels on their occupational stress and depression symptoms , and provide a basis for promoting the physical and mental health of couriers. Methods: From September to December 2021 , 1159 couriers from Zhejiang Express Transport Companies were selected as respondents by cluster sampling , and their basic information were collected. The occupational stress and depression symptoms of the couriers were assessed using the Core Occupational Stress Scale ( COSS ) and the Patient Health Questionnaire-9 ( PHQ-9 ) . The effects of long work hours ( >48 h per week ) on the occupational stress and depression symptoms of the couriers were analyzed. Results: The average age of 1159 courier in Zhejiang Province was ( 33.24±8.42 ) years , the average weekly working hours were ( 63.21±18.77 ) h , and 75.15% (871/1159) were long-term workers. The detection rates of occupational stress and depression symptoms in courier were 32.44% (376/1159) and 32.53% (377/1159), respectively. There were significant differences in the detection rates of occupational stress and depression symptoms among couriers with different ages, educational background, marital status, monthly average income, length of service, position or post, shift status, drinking status, and average weekly working hours ( P <0.05). The adjusted logistic regression analysis showed that, after adjusting for the influence of confounding factors such as age, educational background, marital status, monthly average income, length of service, position or post, shift status and drinking status, compared with the weekly working hours ≤48 h, weekly working hours of 63-77 h, 78-92 h, ≥93 h were the risk factors for occupational stress ( OR =1.547, 95% CI : 1.019-2.350; OR =1.886, 95% CI : 1.184-3.006; OR =2.338, 95% CI : 1.188-4.062) and depression symptoms ( OR =1.897, 95% CI : 1.258-2.860; OR =2.041, 95% CI : 1.290-3.230; OR =4.978, 95% CI : 2.551-9.715) of couriers ( P <0.05) . Conclusion: Long working hours could increase the risk of occupational stress and depression symptoms among couriers. It is necessary to arrange working hours reasonably to reduce the occurrence of occupational stress and depression symptoms of couriers.

Objective: To explore the relationship between occupational stress, psychological capital and depressive symptoms among electronic manufacturing female workers in the Pearl River Delta region. Methods: Using cluster sampling method, 845 female workers from 5 electronic manufacturing enterprises in the Pearl River Delta region were selected as research subjects from June to August 2017. The Effort Reward Imbalance questionnaire (ERI) , Psychological Capital questionnaire-24 (PCQ-24) and Patient Health questionnaire-9 (PHQ-9) were applied to measure the level of occupational stress, psychological capital and depressive symptoms in female workers. Results: Effort ( r =0.197, P <0.01) and over commitment ( r =-0.260, P <0.01) were positively correlated with the score of depressive symptoms, and the rewards was negatively correlated with depressive symptoms ( r =-0.211, P <0.01) . The reward and over-commitment for depressive symptoms were accounted for 8.2%. Psychological capital was negatively correlated with depressive symptoms, and plays a partly mediating role in the relationship between occupational stress and depressive symptoms of female workers. The psychological capital for depressive symptoms was accounted for 8.7%. Conclusion: Occupational stress can affects the depressive symptoms of electronic manufacturing female workers, or indirectly affect depressive symptoms through psychological capital, reduce occupational stress and improve psychological capital as a way to relieve the depressive symptoms of female workers.

Objective: To assess psychological acceptance and occupational stress of medical staff, analyze the relationship among personality, psychological acceptance and occupational stress and discuss the direct or indirect effects of personality to occupational stress. Methods: Eysenck Personality Questionnaire (EPQ-RSC) , Acceptance and Action Questionnaire-II (AAQ-Ⅱ) and Revised Occupational Stress Inventory (OSI-R) were administered to 749 medical staff. Results: The level of occupational stress of medical staff was high, the score of PSY was 26.8±7.13 and the score of PHS was 24.3±6.50. Personality and psychological acceptance can predict occupational stress. Psychological acceptance was a protective factor of occupational stress. Medical staff with personality of introversion, neuroticism and psychoticism suffered higher occupational stress. Personality have both direct and indirect effects on occupational stress. Neuroticism have the strongest effect on occupational stress with effect size of 0.496 (psychological stress) and 0.431 (physical strain) . Conclusion: Medical staff have heavier occupational stress. There is a significant correlation between personality and occupational stress. Measures depending on personality should be taken to deal with this situation.

Objective: To explore the differences of occupational stress and its factors between petroleum refining workers and support staffs, and to propose more targeted measures to promote the health of petroleum refining and petrochemical workers. Methods: A questionnaire survey was conducted among 353 petroleum refining workers and 189 employees in the logistics department using the occupational stress inventory revised edition (OSI-R) scale between June 13, 2017 and July 27, 2017. Results: Among the occupational factors, there were significant differences in the job requirements, work risk, job monotony, participation in the decision - making scores among the male workers between labor group and logistics group ( P <0.01) . And for female workers in the chemical group and logistics group there were also differences in the value of work control, job requirements, work monotonous, work prospects, improvement of opportunity ( P <0.05) . In the aspect of personality traits, the score of work psychological control in chemical group was higher than that of the logistics group, while the organization loyalty score was lower than that of the logistics group. Be-sides, there were significant differences between chemical group and logistics group in the score of A behavior, self-esteem and anxiety traits among female group ( P <0.05) . In terms of mitigating factors, there was a significant difference in social support score between chemical group and logistics group among female workers ( P <0.01) . Comparison of the two groups of psychological stress showed that the mental health and anxiety status of the chemical group and the logistics group showed a difference ( P <0.05) , and female workers in the chemical group job satisfaction score lower than the logistics group, but the body Complaints score higher than the logistics group. Conclusion: The psychological stress response of petroleum refining workers is obviously more serious than the staff of logistics department, and there were significant differences between the two groups on occupational stress factors.

Objective: To investigate the association of occupational stress with job burnout and depression tendency in workers in Internet companies. Methods: From July to November, 2016, the cross-sectional method was used to perform a questionnaire survey of 3603 workers in 35 Internet companies in Beijing, Shandong Province, and Zhejiang Province in China, and the association of occupational stress with job burnout and depression tendency was analyzed. Results: Among these workers, 63.70% had occupational stress with job demand - control (JDC) and 34.60% had occupational stress with effort - reward imbalance (ERI) ; among the workers engaged in sales, 75.63% had occupational stress with JDC and 62.70% had occupational stress with ERI. Of all workers, 10.69% had job burnout, and among the workers engaged in sales, 22.12% had job burnout. Of all workers, 18.79% had the tendency of moderate-to-severe or severe depression, and among the workers engaged in sales, 46.13% had such tendency. Occupational stress with JDC increased the risk of job burnout and depression (odds ratio[ OR ]=3.52 and 1.85, P <0.05) , and occupational stress with ERI also increased the risk of job burnout and depression ( OR =8.24 and 5.59, P <0.05) . In addition, irregular diet and insomnia were risk factors for job burnout; age ≥41 years, low income, sales position, working time spent on the screen ≥10 hours/day, insomnia, and poor self - evaluated health status were risk factors for depression tendency. Conclusion: Occupational stress with JDC and ERI increases the risk of job burnout and depression tendency, and among the workers in Internet companies, the workers engaged in sales have the most severe occupational stress, job burnout, and depression tendency.

Methods: 392 petrochemical workers in Oil refining enterprise were included to conduct the evaluation of the occupational stress, correlation analysis and ridge regression were used to analyze the relationship between occupational stress and five aspects of psychological stress reaction and to detect the influencing factors. Results: Mission control, decision control, environmental control, resources control, promotion, and participation in decision making were positively correlated with job satisfaction ( P <0.01) , technology utilization degree, work order tonality, job prospects were negatively correlated with job satisfaction ( P <0.05) ; mission control, resource control, promotion, participation in decision-making were positively correlated with mental health ( P <0.01) , work order tonality, job prospects were negatively correlated with mental health ( P <0.05) ; load change risk, work, work order tonality, job prospects were positively correlated with depression ( P <0.05) resource control, promotion opportunities were negatively correlated with depression ( P <0.05) ; quantitative risk load, work, work order tonality, job prospects were positively correlated with anxiety ( P <0.05) , the task control, promotion, and participation in decision-making were negatively correlated with anxiety ( P <0.05) ; work, load change, work order tonality, risk scoring for job prospects were positively correlated with body complaint ( P <0.01) , mission control, decision control, resource control were negatively correlated with body complaint ( P <0.05) . Conclusion: Different stress factors make different effects in different psychological stress reaction, the main predictors and predictive power of each psychological stress reaction were not the same.

Objective: This study was to understand the current situation of long working hours and identify the association of long working hours and job stress and depression among workers from one district company of state grid. Methods: The project was done with the cross-sectional survey. All questionnaires were completed by self-administered with informed consent. Employees' weekly working hours was reported by themselves; Using the PHQ-9 scale to assess depression, the JDC Model to evaluate job stress, and SPSS software to analyze data, the single factor chi-square test and multivariate Logistic analysis were performed to identify the association between long working hours and job stress, depression. Results: there were 35.3 percent employees with over 44 hours a week. The association between increasing weekly working hours and job stress and depression was statistically significant. Compared to the reference group (≤44 h) , for those who worked more than 44 hours per week, the odds ratio of job stress was 2.02 (95% CI =1.27-3.23) times increased, and the odds ratio of depression was 1.60 (95% CI =1.01-2.55) times increased, especially for those (≥60 h) , the odds ratio was 3.69 (95% CI =1.45-9.41) and 2.76 (95% CI =1.09-7.03) respectively. Conclusion: Long working hours can significantly increase the risk of job stress and depression among workers. When their weekly working hours exceeds 60, long working hours will be the independent risk factor for both job stress and depression.

Objective: To investigate self-esteem status of train drivers. Methods: By using cluster sampling method, a cross-sectional study was conducted in 1 413 train drivers (including passenger train drivers 301, freight train drivers683, passenger shunting train drivers350, and high speed train drivers79) from a railway bureau. The occupational stressors, strains, self-esteem and personalities were measured using occupational stress instruments and effort-reward imbalance questionnaire. Results: The level of self-esteem is medium ofthe train drivers. Sself-esteem scores among different among different job category (job title) , marry status, age, length of service groups were statistical significance ( P <0.01) . Differences of self-esteem among different educational level, exercise, smoking and drinking groups weren't statistical significance ( P >0.05) . Correlation analysis revealed that self-esteem score was related positively to job satisfaction ( r =0.300) , reward ( r =0.842) , working stability ( r =0.243) , promotion opportunities ( r =0.493) , positive affectivity ( r =0.216) , responsibility for human beings ( r =0.112) and responsibility for things scores ( r =0.108) ( P <0.01) , negatively to sleep quality ( r =-0.103) , social support ( r =-0.212) , role conflict ( r =-0.007) , role ambiguity ( r =-0.169) , physiological needs ( r =-0.115) , daily stress ( r =-0.150) , negative affectivity ( r =-0.252) , depressive symptoms scores ( r =-0.215) ( P <0.01) . Nonparametric test found that train drivers of group with low self-esteem score reported higher scores for physiological need, role conflict, role ambiguity, social sleep quality, depressive symptoms, negative affectivity, social support and daily stress scores than the medium and higher groups ( P <0.01 or<0.05) . But reword, job satisfaction, positive affectivity, copping stratgy, working stability and promotion opportunities scores were lower than the group of medium and higher groups ( P <0.01) . Inter-group conflict scores were insignificance ( P >0.05) . Multivariate logistic regression analysis revealed that low low self-esteem for drivers occured the risk of job dissatisfaction about 1.5 times as high as that of drivers with higher self-esteem ( OR =1.476) Conclusion: Different types of locomotive drivers get different level of self-esteem. Self-esteem was affected by occupational stress largely.

Objective: To study the distribution of sub-health and occupational stress as well as their correlation among middle school teachers in Tianjin, then provide evidences for prevention and control of the status of sub-health. Methods: A total of 3 522 middle school teachers from six districts of Tianjin were recruited with stratified cluster sampling strategy for the investigation of Sub-Health Measurement Scale version 1.0 (SHMS V1.0) and Occupational Stress Inventory-Revised Edition (OSI-R) . Results: Detection rate of sub-health status among Tianjin middle school teachers was 58.55%. Men had significantly lower sub-health detection rate (55.19%) than women (59.71%) . Sub-health detection rate increased with age ( P <0.05) , the sub-health detection rate among middle school teachers more than 50 years old was the highest (66.84%) . The mean score of OSI-R was 403.18±41.80 with the scores of 176.00±21.05, 103.17±17.53, and 124.02±20.28 for ORQ, PSQ, PRQ, respectively, which showed significantly difference compared with the occupational stress norm of China ( P <0.001) . The mean scores of OSI-R, ORQ, PSQ, PRQ in different health status were significantly different ( P <0.001) . The partial correlation analysis between the scores of sub-health and occupational stress of middle school teachers showed that the scores of occupational role and personal strain were negatively correlated with the scores of sub-health state ( P < 0.001) , while, there was significantly positive correlation between the scores of personal resource and the scores of sub-health state ( P <0.001) . Conclusion: Sub-health detection rate of middle school teachers in Tianjin is higher. Effective measures should be taken to appropriately mitigate the occupational stress level of middle school teachers, increase personal resources, and scientific and effective health guidance and education should be strengthened.

Objective: To examine the relationship between recovery experience, occupational stress, and physiological health of nurses in a municipal grade A tertiary hospital. Methods: A total of 296 in-service nurses from 7 municipal grade A tertiary hospitals were selected from October 2015 to February 2016. Individual characteristics of the subjects were collected using a self-made questionnaire. The recovery experience, occupational stress, and physiological health of the subjects were assessed based on the physiological health dimensions in the Chinese version of Recovery Experience Questionnaire (REQ-C) , Job Content Questionnaire (JCQ) , and Quality of Work Life (QWL7-32) . Results: The mean recovery experience score of nurses from the municipal grade A tertiary hospital was 45.04±7.72, and 51.35% of the nurses had satisfactory recovery experience. Occupational stress was identified in 81.76% of the nurses. Based on the four categories of occupational stress, 65 nurses were identified with high-strain jobs (21.95%) , 56 with relaxed (low-strain) jobs (18.92%) , 49 with passive jobs (16.55%) , and 126 with active jobs (42.57%) . In addition, the mean physiological health score of the nurses was 21.20±4.24. Physiological health was negatively correlated with occupational stress ( r =-0.173, P <0.05) , but positively correlated with recovery experience ( r =0.198, P <0.01) . Recovery experience was negatively correlated with occupational stress ( r =-0.116, P <0.05) . Job demand was the major contributor to occupational stress, where subjects with high-demand active jobs had the poorest recovery experience ( F =2.610, P <0.05) and physiological health ( F =8.166, P <0.01) . Conclusion: Job demand has a great impact on the occupational stress of nurses, where increased job demand can lead to stronger stress response, reduced recovery experience, and poorer physiological health.

Objective: To investigate the interaction between mental elasticityand occupational stress and depressionin female nurses and the mediating effect of mental elasticity, as well as the functioning way of mental elasticity in occupational stress-depression. Methods: From August to October, 2015, cluster sampling was used to select 122 female nurses in a county-level medical institution as study subjects. The Connor-Davidson Resilience Scale (CD-RISC) , Occupational Stress Inventory-Revised Edition (OSI-R) , and Self-Rating Depression Scale (SDS) were used to collect the data on mental elasticity, occupational stress, and depression and analyze their correlation and mediating effect. Results: The 122 female nurses had a mean mental elasticity score of 62.4±15.1, which was significantly lower than the Chinese norm (65.4±13.9) ( P <0.05) ; the mean depression score was 41.0±7.7, which was significantly higher than the Chinese norm (33.5±8.6) ( P <0.01) , and the incidence rate of depression of 52.5%. Mental elasticity was negatively correlated with occupational stress and depression ( r =-0.559 and -0.559, both P <0.01) . Occupational stress and the two subscales mental stress reaction and physical stress reaction were positively correlated with depression ( r =0.774, 0.734, and 0.725, all P <0.01) . After adjustment for confounding factors, occupational stress had a positive predictive effect on depression ( β =0.744, P <0.01) , and mental elasticity had a negative predictive effect on depression ( β =-0.221, P <0.01) . The analysis of mediating effect showed a significant direct effect of occupational stress on depression and a significant mediating effect of mental elasticity ( a =-0.527, b =-0.227, c =0.744, c '=0.627; all P <0.01) , and the mediating effect of mental elasticity accounted for 16.08% of the total effect. Conclusion: As a partial mediating variable, mental elasticity has an indirect effect on the relationship between occupational stress and depression and can alleviate the adverse effect of occupational stress and reduce the development of depression.

Objective: To evaluate the current status of job burnout and qual ity of work life (QWL) in workers for offshore oil platforms, and to analyze the relationship of job stress with job burnout and QWL and the direct and indirect effects of job stress on QWL. Methods: Cluster random sampling was used to select 382 work-ers for 8 oil platforms of China National Offshore Oil Corporation in October 2015. A self - designed questionnaire was used to collect the individual characteristics of subjects. The Quality of Work Life Scale (QWL7 - 32) , Occupa-tional Stress Inventory - Revised Edition (OSI - R) , and Maslach Burnout Inventory - General Survey (MBI - GS) were used to investigate the QWL, job stress, and job burnout of subjects. Results: Among all the workers for offshore oil platforms, 87.2% had mild job burnout. The total QWL score was 116.01 ± 16.73; 8.3% of the workers had poor QWL, and 68.5% had moderate QWL. QWL was reduced with heavier task, vaguer task, and increasing mental stress and physical stress ( P <0.05) , and increased with more social support ( P <0.05) . Job stress had di-rect and indirect effects on QWL; stress reaction had the most effect on QWL (total effect size - 0.509) , followed by social support (total effect size 0.444) . Conclusion: Most workers for offshore oil platforms have mild job burn-out and moderate QWL. Job stress is associated with job burnout and QWL, and stress reaction and social support have relatively high influence on QWL.
