ABSTRACT
Background As a group of environmental pollutants, polycyclic aromatic hydrocarbons (PAHs) are neurotoxic and may cause mild cognitive impairment (MCI) by inducing inflammation. Whether neutrophil-lymphocyte ratio (NLR), an inflammatory indicator, plays a mediating role in the relationship between PAHs exposure and MCI is unclear yet. Objective To investigate a potential mediating role of NLR in the association between exposure to PAHs and MCI in coke oven plant workers. Methods Eleven urine hydroxylated PAHs (OH-PAHs) of 530 coke oven plant workers were determined by high performance liquid chromatography tandem mass spectrometry. NLR was derived from participants' routine blood examination results using a fully automated haematology analyser. The associations between urinary OH-PAHs and MCI were analyzed by binary logistic regression, the associations between urinary OH-PAHs and NLR were analyzed by multiple linear regression, and the role of NLR in the relationship between urinary OH-PAHs and MCI was evaluated by mediating effect analysis. Results After controlling for confounding factors and other OH-PAHs, the results of binary logistic regression showed that for every e-fold (e is the base of the natural logarithm) increase in the concentration of 2-hydroxynaphthalene (2-OHNap) and 1-hydroxyphenanthrene (1-OHPhe), the OR (95%CI) values of reporting MCI positive were 1.21 (1.02, 1.43) and 1.25 (1.04, 1.51) respectively. For each unit increase of NLR, the OR (95%CI) of reporting MCI positive was 1.56 (1.12, 2.18). The results of multiple linear regression showed that each unit increase in natural log-transformed levels of 1-OHPhe was associated with 0.05 (95%CI: 0.01, 0.10) increase of NLR. The results of mediating effect analysis showed that the association between urinary 1-OHPhe and MCI was partially mediated by peripheral blood NLR, with a mediation ratio of 9.8%. Conclusion Exposure to PAHs in coke oven plant workers may increase the risk of reporting MCI positive partially through increased NLR in peripheral blood.
ABSTRACT
Objective:To investigate the relationship between self-control and obsessive-compulsive symptoms(OCS), and the mediating role of procrastination and anxiety in this relation.Methods:Totally 6 367 Chinese college students were recruited to complete the Chinese version of the self-control scale, the Aitken procrastination inventory, and the symptom checklist-90.Descriptive analysis and Pearson correlation were carried out using SPSS 23.0.Mplus 7.4 was used to test the model fit.The mediating effects were tested using the Bootstrap method.Results:Pearson correlation analysis showed that there were significant correlations among self-control, procrastination, anxiety, and obsessive-compulsive symptoms ( r=-0.71-0.78, P<0.01). Mediation modeling analysis showed that the total indirect effect of self-control on OCS was -0.303, accounting for 63.13% of the total effect.The mediating effect of procrastination between self-control and OCS was -0.045, accounting for 9.38% of the total effect.The mediating effect of anxiety between self-control and OCS was -0.239, accounting for 49.79% of the total effect.Moreover, the chain mediating effect of procrastination and anxiety between self-control and OCS was also significant, with an effect value of -0.019, accounting for 3.96% of the total effect. Conclusion:Self-control can negatively predict OCS, procrastination and anxiety play a chain mediating role in the effect of self-control on OCS.
ABSTRACT
Objective:To explore the impact of stress perception on depression and the potential mediating role of resilience in medical staff.Methods:A total of 606 medical staff were recruited and investigated by self-designed questionnaire, the perceived stress scale (PSS-10), the 10-item Connor-Davidson resilience scale (CD-RISC-10), and the patient health questionnaire-9 (PHQ-9) from February to March, 2020.SPSS 26.0 software was used to execute Pearson or Spearman correlation analysis, common method biases test, and multicollinearity test.Model 4 in PROCESS 3.2 macro program and Bootstrap method were used for mediating effects analysis.Results:There was a positive correlation between stress perception score(16.93±6.65) and depression score (5.00(2.00, 9.00))( r=0.551, P<0.01), and a negative correlation between stress perception score and resilience score (27.08±8.68) ( r=-0.285, P<0.01) among 606 medical staff.There was a negative correlation between resilience score and depression score ( r=-0.474, P<0.01). Mesometric effect examination showed that resilience played a partial mediating role in the relationship between stress perception and depression, and the mediating effect accounted for 10.87% of the total effect. Conclusion:Stress perception can directly or indirectly influence depression scores, and resilience partially mediates the relationship between stress perception and depression.Depression can be reduced clinically by reducing stress perception or enhancing the resilience of medical personnel.
ABSTRACT
Objective:To explore the mediating effects of mindfulness and perceived stress between childhood trauma and psychotic-like experiences.Methods:In October 2021, 602 freshmen from a university in Guangdong Province were tested by childhood trauma questionnaire(CTQ), mindful attention awareness scale(MAAS), perceived stress scale(PSS), and community assessment of psychic experiences(CAPE). SPSS 21.0 and Mplus 8.3 were used for data analysis. Mann-Whitney U test was used to compare the differences between groups, and Spearman correlation analysis was used to investigate the correlation among childhood trauma, mindfulness, perceived stress and psychotic-like experiences. Bias-corrected nonparametric percentile Bootstrap method was used to examine the mediating roles of mindfulness and perceived stress between childhood trauma and psychotic-like experiences. Results:(1) In the past one month, 59.5% of the freshmen had psychotic-like experiences, and 8.5% of them experienced the distress. (2)Childhood trauma was positively correlated with perceived stress( r=0.29, P<0.01), frequency ( r=0.14, P<0.01)and distress( r=0.17, P<0.01) of psychotic-like experiences, and was negatively correlated with mindfulness( r=-0.28, P<0.01). (2)Mindfulness and perceived stress played individual mediating effects and chain mediating effect between childhood trauma and frequency of psychotic-like experiences, with effect size of 0.08, 0.04, 0.03, accounting for 53.33%, 26.67%, 20.00% of the total indirect effect(effect size=0.15), respectively. Mindfulness and perceived stress played individual mediating effects and chain mediating effect between childhood trauma and distress of psychotic-like experiences, with effect size of 0.07, 0.04, 0.03, accounting for 50.00%, 28.57%, 21.43% of the total indirect effect(effect size=0.14), respectively. Conclusion:Childhood trauma can affect psychotic-like experiences and distress through the indirect effects of mindfulness and perceived stress, or through the chain mediating effect of mindfulness-perceived stress.
ABSTRACT
Objective:To explore the mediating effect of empathy between personality traits and death attitude in nursing students.Methods:From April to May 2022, a total of 237 undergraduate nursing students were surveyed by general information questionnaire, big five inventory, Jefferson scale of empathy for nursing students, and death attitude profile-revised. Common method bias test, correlation analysis and descriptive analysis were conducted by SPSS 26.0 software.PROCESS macro program was used to test the mediating effect.Results:Agreeableness(32.78±4.92), empathy(110.03±16.83)were positively correlated with positive death attitude(57.95±12.35)( r=0.274, 0.571, both P<0.01), neuroticism(23.00±4.78)was positively correlated with negative death attitude(31.81±10.04)( r=0.199, P<0.01), empathy was negatively correlated with negative death attitude ( r=-0.226, P<0.01). Empathy partially mediated the relationship between neuroticism and negative death attitude, the mediating effect accounted for 16.08%(0.032/0.199) of the total effect, and empathy played a completely mediating role between the agreeableness and positive death attitude. Conclusion:The death attitude of undergraduate nursing students is mainly natural acceptance. Personality traits can directly affect death attitude and also indirectly affect death attitude through empathy.
ABSTRACT
Objective:To investigate the mediating roles of the fear of missing out and mobile phone addiction between the basic psychological needs satisfaction and phubbing behavior among high school students.Methods:In April 2022, a cross-sectional design survey was conducted on 14 666 high school students. All participants were evaluated by the basic psychological needs scales(BPNS), generic scale of phubbing(GSP), trait-state fear of missing out scale(T-S FOMOS) and mobile phone addiction index(MPAI). The SPSS 26.0 software was used to conduct common method deviation test, descriptive statistics, and correlation analysis.PROCESS 4.1 was used to construct the model, and the Bootstrap method was used to test for mediating effects.Results:(1)Among the 14 036 high school students, there were 1 752 (12.48%) students who were addicted to mobile phones.There were significant differences in gender in the scores including BPNS(boy: 4.43±0.79, girl: 4.36±0.79), GSP(boy: 2.72±1.01, girl: 2.76±1.03) and T-S FOMOS(boy: 1.73±0.60, girl: 1.84±0.64), ( t=5.22, -10.58, -2.78, all P<0.01). Among different grades, there were significant differences in the scores of BPNS, T-S FOMOS, MPAI, and GSP( F=25.43, 39.50, 53.45, 14.59, all P<0.01). (2)Basic psychological needs score were positively correlated with fear of missing out, mobile phone addiction and phubbing( r=-0.432--0.294, all P<0.01). Phubbing were negatively correlated with fear of missing out and mobile phone addiction( r=0.744, 0.538, both P<0.01). Fear of missing out were negatively correlated with mobile phone( r=0.646, P<0.01). (3)The basic psychological needs satisfaction had a direct effect on phubbing behavior, and the effect value was -0.188 (95% CI: -0.173--0.204). The mediating effect of fear of missing out between the basic psychological needs satisfaction and phubbing behavior was -0.035(95% CI: -0.028--0.042). The mediating effect of mobile phone between the basic psychological needs satisfaction and phubbing behavior was -0.203(95% CI: -0.191--0.214). Fear of missing out and mobile phone addiction played a chain mediating role between them, and the mediating effect value was -0.134(95% CI: -0.125--0.143), which accounted for 23.93%(-0.134/-0.560) of the total effect. Conclusion:The high level basic psychological needs satisfaction can alleviate the occurrence of phubbing behavior. It may be achieved by decreasing fear of missing out and reducing mobile phone addiction.
ABSTRACT
Objective:To explore the relationship between negative evaluation fear and mobile phone addiction, and the mediating role of balanced time perspective.Methods:In April 2021, totally 1 158 secondary vocational school students were investigated by scales of fear of negative evaluation(FNE), mobile phone addiction index(MPAI)and Zimbardo time perspective inventory(ZTPI). The balanced time perspective was calculated by deviation from the balanced time perspective(DBTP). SPSS 20.0 statistical software was used for descriptive statistical analysis and correlation analysis of the data.Bootstrap method was used to test the mediating effect.Results:(1) Negative evaluation fear(37.87±7.71)was significantly positively correlated with balanced time perspective(4.50±0.75)( r= 0.379, P<0.01) and mobile phone addiction(46.11±11.92)( r=0.437, P<0.01). The balanced time perspective was significantly positively correlated with mobile phone addiction( r=0.475, P<0.01). (2) Negative evaluation fear directly and positively predicted mobile phone addiction( β=0.300, 95% CI=0.248-0.352). The balanced time perspective played a partial mediating role between negative evaluation fear and mobile phone addiction, and the mediating effect value was 0.137, accounted for 31.31%(0.137/0.437) of the total effect. Conclusion:The fear of negative evaluation can directly affect the mobile phone addiction behavior of secondary vocational students, and can also indirectly affect the mobile phone addiction by affecting the balanced time perspective.Good balanced time perspective can reduce the risk caused by the fear of negative evaluation.

SPSS 25.0 software was used for common method deviation test, descriptive statistics and correlation analysis, while AMOS 24.0 software was used to build structural equation model and Bootstrap method was used for intermediary effect test. Results:(1)The prevalence of cognitive impairment among the elderly in the community was 14.1%. The differences between the cognitively normal group and cognitively impaired group were statistically significant in terms of age, education, number of chronic diseases suffered and depression ( χ2=59.21, 6.53, 9.84, 25.47, all P<0.05). The differences were statistically significant in terms of frailty( χ2=75.65, P<0.001) and self-perceptions of aging ( t=77.67, P<0.001). (2)Self-perceptions of aging in the cognitively impaired group (47.39±8.66) was higher than that in the cognitively normal group (38.22±8.24) ( t=77.67, P<0.001) .Frailty score in cognitively impaired group (2.00 (1.00, 3.00)) was higher than that in the cognitively normal group (0.00 (0.00, 1.00))( Z=-8.63, P<0.001) . (3)Frailty was negatively correlated with cognitive function ( r=-0.492, P<0.01), and positively correlated with self-perceptions of aging ( r=0.540, P<0.01). Self-perceptions of aging was negatively correlated with cognitive function ( r=-0.541, P<0.01) . After controlling the influencing factors such as age, education level, chronic diseases and depression, the correlation was still significant (all P<0.01) . (4) Self-perceptions of aging played a partially mediating role in the relationship between frailty and cognitive function, the mediating effect accounted for 58.5% of the total effect. Conclusion:Frailty and self-perceptions of aging have a significant impact on the cognitive function of the elderly in the community, and self-perceptions of aging plays a partial intermediary role between the frailty and cognitive function of the elderly in the community.
ABSTRACT
Objective:To explore the relationship between self-perceptions of aging and cognitive function, and the mediating and moderating effect of loneliness among them.Methods:A multi-stage stratified sampling was conducted in Jinzhou from September to November 2021, and 318 community-based elderly were included.General data questionnaire, the brief ageing perceptions questionnaire (BAPQ), UCLA loneliness scale(UCLA-LS) and mini-mental state examination (MMSE) were applied to all subjects.IBM SPSS 25.0 software was used to conduct independent sample t-test, analysis of variance and Pearson correlation analysis, and Bootstrap program of AMOS 22.0 was used to analyze the mediation effect.The model in SPSSAU on-line analysis program was used to test the moderating effect.

ABSTRACT
Objective To explore the current status of emotional exhaustion among clinical nurses and its relationship with work stress, thought suppression, difficulties in emotion regulation. Methods A totally of 1 159 clinical nurses from 10 cities in Henan Province and Fujian Province were enrolled as the research subjects using grabbing random balls method. And their status of work stress, thought suppression, difficulties in emotion regulation and emotional exhaustion were investigated by Depression-Anxiety-Stress Scale, White Bear Suppression Inventory, Brief Version of the Difficulties in Emotion Regulation Scale and Emotional Exhaustion Scale. Results The scores for work stress, thought suppression, difficulties in emotion regulation, emotional exhaustion were (23.5±3.8), (47.4±6.5), (54.1±7.2), (11.7±4.2), respectively. Among them, 40.0% of nurses experienced emotional exhaustion. Bootstrap analysis results showed that work stress positively affected emotional exhaustion among clinical nurses [standardized partial regression coefficient (β)=0.42, 95% confidence intervals (CI)： 0.36-0.44］. Work stress affected emotional exhaustion through thought suppression (β=0.16, 95%CI： 0.14-0.20), difficulties in emotion regulation (β=0.16, 95%CI： 0.14-0.19), and the chain mediating role of thought suppression and difficulties in emotion regulation (β=0.07, 95%CI： 0.04-0.09). Conclusion Emotional exhaustion symptoms are prevalent among clinical nurses. Work stress directly and indirectly influences thought suppression, difficulties in emotion regulation and emotional exhaustion of nurses.
ABSTRACT
Objective: To investigate the mechanisms of work-family conflict (WFC) and work-family enrichment (WFE) between job demands and subjective well-being (SWB) among nurses. Methods: A total of 1 420 nurses were selected as the study subjects from five tertiary public hospitals in Shandong Province using two-stage sampling method. Job Demands-Resources Scale, Work-Family Relationship Scale and General Well-Being Scale were used for investigating the job demands, job resources, WFC, WFE, and SWB. Results: The average score of SWB in nurses was (75.5±15.1). Job demands had a negative effect on SWB in nurses (standardized regression coefficient=-0.17, P<0.01). WFC and WFE played parallel mediating roles in the relationship between job demands and SWB, with the mediating effect values of -0.29 and -0.07, respectively (both P<0.01). The interaction of job resources and job demands positively affected WFC (standardized regression coefficient<0.01, P<0.01). Conclusion: Job demands affect SWB through the mediating roles of WFC and WFE, and the impact of job demands on WFC is moderated by job resources. The effect of job demands on WFC is relatively strong in nurses with high levels of job resources, but the difference in the effect of high and low levels of job resources is small.
ABSTRACT
Objective: To study the relationship between compassion fatigue and workplace psychological violence, alexithymia, and empathy in clinical nurses. Methods: A total of 1 159 clinical nurses from 10 cities in Henan and Fujian Provinces were enrolled using the method of grabbing random balls. Questionnaires including Workplace Psychologically Violent Behaviors Instrument, the Toronto Alexithymia Scale, Jefferson Scale of Empathy Health Professionals, Professional Quality of Life Scale were used to investigate the status of workplace psychological violence, alexithymia, empathy, and compassion fatigue in participants. Bootstrap analysis was used to analyze the relationship between workplace psychological violence, alexithymia, empathy, and compassion fatigue scores. Results: The average score for workplace psychological violence among clinical nurses was (26.2±6.5), with 405 nurses (34.9%) having experienced workplace psychological violence. The scores for alexithymia, empathy and compassion fatigue were (58.3±12.3), (104.3±18.6) and (48.5±6.7) respectively. Mild compassion fatigue was detected in 34.9% of participants, while moderate to severe compassion fatigue accounted for 48.8%. Bootstrap test result showed that workplace psychological violence had a positive impact on compassion fatigue ［standardized effect value (β)=0.40, 95% confidence interval(CI)： 0.35-0.44］. Workplace psychological violence had separate mediating effects through alexithymia (β=0.15, 95%CI： 0.10-0.19), empathy (β=0.16, 95%CI： 0.10-0.21) , and a chain mediating effect through alexithymia and empathy on compassion fatigue (β=0.06, 95%CI： 0.03-0.09). Conclusion: Compassion fatigue symptoms are relatively common among clinical nurses. Experiencing workplace psychological violence directly affects compassion fatigue and can indirectly affect it through the mediating effects of alexithymia and empathy.
ABSTRACT
Objective: To study the relationship between compassion fatigue and overall happiness among firefighters, and the mediating role of psychological stress and positive psychological capital. Methods: A total of 894 firefighters in Shandong Province were selected as the research subjects using purposive sampling method. Questionnaires including the Professional Quality of Life Scale, the Military Psychological Stress Self-Assessment Scale, the Positive Psychological Capital Scale, and the Overall Happiness Scale were used for data collection. Results: The scores of compassion fatigue, psychological stress, positive psychological capital and overall happiness among firefighters were (40.1±13.5), (13.9±3.9), (133.0±26.4) and (84.9±15.2), respectively. There were correlations between compassion fatigue, psychological stress, positive psychological capital and overall happiness (all P<0.01). Psychological stress partially mediated the relationship between compassion fatigue and overall happiness, and the mediating effect accounted for 27.0% of the total effect. Positive psychological capital moderated the front half path and the direct path between compassion fatigue and overall happiness (all P<0.01). Conclusion: Compassion fatigue can directly or indirectly affect the firefighters' overall happiness. Psychological stress plays a partial mediating role and positive psychological capital plays a moderating role between compassion fatigue and overall happiness.

Objective:To construct and validate a theoretical model of residents′ willingness to participate in tiered medical care based on harmonious management theory, providing reference for promoting the tiered medical care system and aiding governmental decision-making.Methods:Based on the harmonious management theory and literature review, a model capturing residents′ propensity to engage in tiered medical care was formulated. Using convenience sampling method, a questionnaire survey was conducted on 2 067 residents from 24 communities in Zhejiang province from April to May 2022. Descriptive statistical analysis was conducted on the survey results, and multilevel linear regression and structural equation modeling were used to analyze the driving mechanism of residents′ willingness to participate in tiered medical care.Results:The willingness rate of residents to participate in tiered medical care was 69.7%, which was at an average level. Regression insights highlighted the positive influence of policy support perception ( β=0.170, P<0.01), awareness of management mechanisms ( β=0.093, P<0.01), cognitive attitudes ( β=0.102, P<0.01), and trust levels ( β=0.244, P<0.01) on residents′ participation willingness. In contrast, resource allocation perceptions lacked a significant effect ( β=0.065, P>0.05). The structural equation model revealed that cognitive attitudes played a mediating role in the " policy system perception → participation willingness" and " management mechanism perception → participation willingness" pathways, with effect sizes of 0.030 and 0.039, respectively. Trust levels also mediated these paths, with effect sizes of 0.039 and 0.045, and entirely mediated the " resource allocation perception → participation willingness" path, registering an effect size of 0.053. Conclusions:The harmonious management theory can be used to explain the formation mechanism of residents′ willingness to participate in tiered medical care. The government and medical institutions urgently need to further improve residents′ awareness of tiered medical care, focus on enhancing residents′ trust, and further improve policies and management measures such as financial investment, medical insurance reimbursement, and referral systems.
