ABSTRACT
Background The mental health status of prison officers is crucial to the efficiency, security, and stability of a prison, and it is essential to pay attention to the factors that influence their mental health. Objective To understand the mental health status of prison officers, and analyze how nature exposure affects their mental health problems and a potential mediating role of mental fatigue. Methods A cross-sectional survey was carried out from May to June 2022 among 1392 prison officers from eight prisons in a province, and a total of 1284 valid questionnaires were recovered. The Nature Exposure Scale, Mental Fatigue Scale, and Depression-Anxiety-Stress Scale were used to assess nature exposure, mental fatigue, and mental health indicators among prison officers, and to explore the effect of nature exposure on mental health problems and a potential mediating role of mental fatigue. Results The recruited prison officers showed high levels of depression, anxiety, and stress. The prevalence rates of depression, anxiety, and stress were 59.11% (759/1284), 60.67% (779/1284),and 43.93% (564/1284), respectively. The results of correlation analysis revealed that nature exposure was negatively related with mental fatigue and mental health indicators (depression, anxiety, and stress) (rs=−0.242, −0.308, −0.235, −0.254, P<0.01), while mental fatigue was positively correlated with mental health indicators (depression, anxiety, and stress) (rs=0.546, 0.533, 0.536, P<0.01). The PROCESS macro results showed that the level of nature exposure among prison officers negatively associated with depression, anxiety, and stress (β=−0.180, −0.104, −0.123), and mental fatigue played a mediating role, with indirect effects of −0.200, −0.192, and −0.199, respectively. Conclusion The levels of depression, anxiety, and stress of prison officers are higher than those of other occupations. Nature exposure negatively associates with depression, anxiety, and stress, that is, it may directly alleviate the mental health problems of prison officers; and it may also alleviate mental health problems by relieving mental fatigue.
ABSTRACT
Background Job burnout has become an important factor affecting the mental and physical health and work efficiency of college counselors, and indirectly affects the quality and development of talent cultivation for college students. Objective To explore the relationship between job stress, job crafting, and job burnout among college counselors, and to test the mediating role of job crafting between job stress and job burnout, in order to take targeted measures to alleviate job stress and job burnout of college counselors, reduce associated health risks, and improve the effectiveness of higher education. Methods An anonymous questionnaire survey was conducted among 400 counselors from social network communication groups by convenience sampling. The Counselor Work Stress Scale, Job Crafting Scale, and Maslach Burnout Inventory-General Survey were used. Harman's single-factor method was used to evaluate common method bias in the survey data. One-way ANOVA was applied to test the difference in job stress, job crafting, and job burnout among college counselors by demographic characteristics, and chi-square test was used to analyze the difference in reporting job burnout. Partial correlation analysis was used to evaluate the correlation between selected variables. Structural equation modeling was used to analyze the relationship of job stress, job crafting, and job burnout among college counselors, and Bootstrap analysis was used to test if there was a mediating effect of job crafting on the relationship between job stress and job burnout. Results Of the 390 questionnaires recovered, there were 338 valid questionnaires (86.67%). Among the included subjects, the mean scores of job stress, job crafting, and job burnout were (2.70±0.62), (3.77±0.62), and (2.09±1.09), respectively. The positive rate of job burnout was 76.9% (260/338), with a positive rate of 72.8% in exhaustion dimension and 59.8% in cynicism dimension. There were significant differences in job crafting scores among the college counselors by different genders and professional titles (P<0.05). Female counselors had significantly higher job burnout scores and positive rates than male counselors (P<0.05). The partial correlation analysis showed that job stress, work load, school evaluation and expectation, and interpersonal relationship were positively correlated with job burnout (r=0.562, 0.442, 0.473, and 0.455, respectively, P<0.01), and negatively correlated with job crafting (r=−0.271, −0.169, −0.246, and −0.247, respectively, P<0.01); job crafting, cognitive crafting, relationship crafting, and task crafting were negatively correlated with job burnout (r=−0.447, −0.452, −0.366, and −0.340, respectively, P<0.01). The modified structural equation modeling indicated that job stress negatively affected job crafting (b=−0.348, P<0.001) and positively affected job burnout (b=0.454, P<0.001); job crafting negatively affected job burnout (b=−0.459, P<0.001), and played a partial mediating role in the relationship between job stress and job burnout, and the effect value was 0.160 (95%CI: 0.102, 0.230) that accounted for 26.10% of the total effect. Conclusion Job burnout among the college counselors is prominent. Job crafting presents an inhibitory effect on job burnout. Job stress indirectly affects the occurrence of job burnout by inhibiting the generation of job crafting.

ABSTRACT
Background Front-line power grid workers are required to face a variety of occupational hazards (such as aerial work), which make them susceptible to psychological problems and further reduce their performance efficiency and safety level. Objective To investigate the mental health status of front-line power grid workers and explore the influence of personality traits on mental health and the potential mediating role of work-family support between them. Methods This study was designed as a cross-sectional study. From January to June 2019, a cluster random sampling method was used to select two of the 20 power supply stations owned by a Guangdong power company. A total of 485 front-line power grid workers were included in the study. Sociodemographic characteristics were investigated, and NEO Five-Factor Inventory, Work-Family Support Scale, and Symptom Checklist 90 (SCL-90) were used in the survey. Spearman correlation analysis was conducted to analyze the correlations between measured variables. Structural equation modeling was used to analyze the relationships of personality traits, work-family support, and mental health, and Bootstrap analysis was used to test the mediating effect of work-family support on the relationship of personality traits and mental health. Results The M (P25, P75) of total SCL-90 score was 134.00 (110.00, 167.00）, and 139 (28.66%) front-line power grid workers showed positive mental health symptoms. The correlation analysis indicated that among the front-line power grid workers, neuroticism score was negatively correlated with work-family support total score (rs=−0.356, P<0.001), and positively correlated with the total score of SCL-90 (rs=0.557, P<0.001) as well as all the scores of its sub-dimensions (rs=0.436-0.550, P<0.001). Openness score was positively correlated with work-family support total score (rs=0.269, P<0.001), and except for paranoid ideation (P>0.05), openness score was negatively correlated with the scores of all the other sub-dimensions of SCL-90 (rs=−0.091-−0.147, P<0.05). The scores of the other three personality traits (extroversion, agreeableness, and conscientiousness) were positively correlated with work-family support total score (rs=0.331-0.466, P<0.001), and negatively correlated with the total score of SCL-90 as well as the scores of all its sub-dimensions (P<0.001). The modified structural equation modeling indicated that the direct effect of work-family support on mental health symptoms was −0.225 (P<0.001). The direct effects of extraversion and openness on work-family support were 0.241 (P<0.001) and 0.123 (P<0.05), respectively, while the effect on mental health symptoms was not statistically significant. The direct effects of neuroticism on work-family support and mental health symptoms were -0.152 (P<0.01) and 0.467 (P<0.001), respectively. The direct effects of conscientiousness on work-family support and mental health symptoms were not statistically significant (P>0.05). The direct effect of agreeableness on work-family support was not statistically significant (P>0.05), while the direct effect on mental health symptoms was −0.180 (P<0.001). Conclusion The front-line power grid workers show a high score of SCL-90. Workers with higher neuroticism are more vulnerable to mental health symptoms. Work-family support fully mediates the effects of extraversion and openness on mental health symptoms, and partially mediates the effects of neuroticism on mental health symptoms, while does not mediate the effects of agreeableness on mental health symptoms. Sufficient work-family support may improve mental health status.
ABSTRACT
Background Occupational aluminum exposure may associate with cognitive impairment in workers. At present, brain functional imaging data are not available for evaluating cognitive dysfunction in workers with occupational exposure to aluminum. The role of brain functional connectivity in cognitive decline associated with occupational aluminum exposure is not clear yet. Objective To explore potential mediating effect of brain functional connectivity value on cognitive decline induced by occupational aluminum exposure, to assess the relationship between cognitive impairment and brain functional connectivity, and to identify appropriate imaging evidence of early cognitive changes induced by occupational aluminum exposure. Methods This study used a subset data from a previous cross-sectional survey. Based on the data of aluminum-exposed workers, over 40 years old, aluminum-exposed working years >1 year, Montreal International Cognitive Assessment (MoCA) (Beijing version) score <26 points, 20 workers were selected as the case group, and 40 healthy workers with the same basic conditions (age, smoking, drinking, etc.) in non-aluminum production were selected as the control group with a 1∶2 matching ratio. The basic information of the subjects was collected, plasma aluminum level and cognitive function level were evaluated, and different brain functional connectivity values of default mode network (DMN) were measured by magnetic resonance imaging. The mediating effect analysis was conducted to examine the role of brain functional connectivity in the relationship between aluminum exposure and cognitive function. Results The plasma aluminum concentration of the case group was 1.76 times higher than that of the control group [(33.04±12.02) µg·L−1 vs (18.74±8.95) µg·L−1, P<0.05]; the MoCA score was 9.5 points lower [(18.35±2.64) vs (27.85±0.92), P<0.05]. The mean functional connection values of DMN1 and DMN2 in the case group were lower than those in the control group (P<0.05). The mean functional connection values of the left precuneus, left middle cingulate cortex, left superior medial gyrus, left precentral gyrus, and left cerebellum also decreased in the case group compared with the control group (P<0.05). Plasma aluminum concentration was negatively correlated with DMN1 functional connectivity value and MoCA scores (b=−0.004, 95%CI: −0.008–−0.001; b=−0.15, 95%CI: −0.233–−0.067; P<0.05). The mean functional connection values of DMN1 and DMN2 were positively correlated with MoCA scores (b=10.945, 95%CI: 5.574–16.316; b=10.107, 95%CI: 2.457–17.758; P<0.05). With the increase of plasma aluminum concentration, MoCA score decreased, but when the plasma aluminum concentration exceeded 19.50 µg·L−1, MoCA score decreased slowly. With the increase of the mean functional connectivity value of DMN1, MoCA score increased, but when the mean functional connectivity value of DMN1 exceeded 1.05 and continued to increase, the increase of MoCA score slowed down. The results of mediating effect analysis showed that the functional connectivity value of DMN1 partially mediated the relationship between plasma aluminum concentration and MoCA score, and the mediating effect was 25.80%. Conclusion Cognitive impairment in occupational aluminum-exposed workers is closely related to brain resting-state functional connectivity. There is a dose-response relationship of plasma aluminum concentration with DMN1 functional connectivity value and MoCA scores, and DMN1 functional connectivity value partially mediates the relationship between plasma aluminum concentration and MoCA scores. The brain functional connectivity value can be used as meaningful imaging data to study the cognitive decline induced by chronic aluminum exposure.
ABSTRACT
Background The correlation between noise exposure and negative emotions of noise-exposed workers has received increasing attention and related studies have been reported. However, there is a lack of research on the path and effect analysis of the relationship between noise exposure and negative emotions, which will contribute to a more comprehensive understanding of the health damage characteristics of noise in addition to hearing loss. Objective To explore the path and effects of cumulative noise exposure, tested hearing thresholds, and conscious hearing level of noise-exposed workers on negative emotions. Methods Using stratified random sampling, 312 noise-exposed workers from a machinery and equipment manufacturing enterprise were selected. Occupational history, negative emotions (including the feelings of stress, anxiety, and depression), and conscious hearing level of the workers were investigated using the Depression-Anxiety-Stress Scale (DASS-21) and a self-made questionnaire. The hearing threshold of the workers was measured by pure tone air conduction audiometry. Sound level meter was used to measure noise equivalent sound level at selected work sites. Individual cumulative noise exposure was estimated based on work site noise level and personal noise exposure history. Path analysis was used to analyze potential mediating effects of workers' hearing thresholds and conscious hearing levels on the relationship between noise exposure and negative emotions (including stress, anxiety, and depression). Results The positive rates of negative emotions among the 312 noise-exposed workers were 18.27% (57/312) for stress, 46.79% (146/312) for anxiety, and 28.53% (89/312) for depression; the cumulative noise exposure ranged from 101.0 to 136.1 dB(A)·d, with an average of 125.69 dB(A)·d. The distributions of tested hearing thresholds and conscious hearing levels among the workers exposed to noise were significantly inconsistent (P<0.001), with both unweighted and weighted Kappa values less than 0.4. The percentage of workers with conscious hearing levels higher than their hearing threshold levels was 16.0%, and the percentage of workers with conscious hearing levels lower than conscious hearing levels was 38.7%. The path analysis results showed that tested hearing thresholds had no mediating effect on the relationship between cumulative noise exposure and negative emotions. There was a partial mediating effect of conscious hearing level on the relationship between cumulative noise exposure and negative emotions, with a mediating effect value of 0.06 (95%CI: 0.03, 0.11) and a mediating effect ratio of 28.57%. Conclusion Conscious hearing plays a partial mediating role in the relationship between cumulative noise exposure and negative emotions of noise-exposed workers, while tested hearing thresholds do not.
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.
ABSTRACT
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.
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).

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.

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.
ABSTRACT
Objective:To explore the mediating effect of experiential avoidance and emotional eating between intolerable uncertainty and life satisfaction of college students.Methods:From October to December 2021, a total of 890 college students in the Beijing-Tianjin-Hebei region were tested by the intolerable uncertainty scale (simplified version), the acceptance action scale second edition, the Dutch eating behavior questionnaire and the life satisfaction scale. All data processing and analysis were preformed by SPSS 22.0 software, and the mediating effect was tested by Pearson correlation analysis and Bootstrap analysis.Results:The intolerable uncertainty score was (26.43±7.64), the experiential avoidance score was (22.63±9.67), the emotional eating score was (26.43 ±11.83), and the life satisfaction score was (16.74±6.03). Intolerable uncertainty was significantly and negatively correlated with life satisfaction( r=-0.76, P<0.01), and was significantly and positively correlated with experience avoidance and emotional eating( r=0.66, 0.78, both P<0.01). Experience avoidance was significantly and positively correlated with emotional eating( r=0.70, P<0.01), and was significantly and negatively correlated with life satisfaction( r=-0.62, P<0.01). Emotional eating was significantly and negatively correlated with life satisfaction( r=-0.68, P<0.01). Intolerable uncertainty affects life satisfaction through four paths.The direct effect value of intolerable uncertainty on life satisfaction was -0.53, accounting for 70.23% of the total effect. The separate mediating effect value of experience avoidance was -0.11, accounting for 50.00% of the total indirect effect.The separate mediating effect value of emotional eating was -0.08, accounting for 36.36% of the total indirect effect, and the chain mediating effect value of experience avoidance and emotional eating was -0.03, accounting for 13.64% of the total indirect effect. Conclusion:Intolerable uncertainty can directly affect life satisfaction of college students and indirectly through experiencing avoidance and emotional eating.
ABSTRACT
Objective:To explore the mediating role of self-perceptions of aging between frailty and cognitive function in community-dwelling older adults.Methods:From February to July 2021, a total of 528 elderly people in Xinxiang community were investigated with the frailty phenotype, the brief self-perceptions ageing questionnaire and the Mini-mental state examination(MMSE) scale.According to the MMSE total score and education level, the subjects were divided into cognitive impairment group (illiteracy≤17, primary school≤20, junior high school and above≤24, n=74) and cognitive normal group( n=454). 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. Results:The average scores of self-perceptions of aging, loneliness and cognitive function were (44.85±12.48), (41.70±8.73) and (24.87±3.40) respectively.And 65 of 318 subjects had cognitive impairment, and the detection rate was 20.44%(65/318). Self-perceptions of aging, loneliness and cognitive function scores were significantly correlated between each other(all P<0.05). Self-perceptions of aging had a negative effect on cognitive function ( β=-0.467, P<0.01). Self-perceptions of aging had a positive effect on loneliness ( β=0.585, P<0.01). Loneliness had a negative effect on cognitive function ( β=-0.234, P<0.01). The indirect standardization effect of loneliness between self-perceptions of aging and cognitive function was -0.137, and the mediating effect accounted for 22.68% of the total effect.Loneliness played a moderating role between self-perceptions of aging and cognitive function ( β=-0.114, t=-2.26, P=0.025). Conclusion:Self-perceptions of aging and loneliness can predict the cognitive function in the elderly, and loneliness plays a mediating role between self-perceptions of aging and cognitive function.Early detection of negative senility emotion and loneliness of the elderly will play a positive role in preventing the occurrence of cognitive impairment.
ABSTRACT
Objective:To explore the relation among self-esteem, psychological flexibility and mental health in medical students, and to provide scientific reference for mental health education for medical students.Methods:A total of 788 medical students selected from a medical university in Chongqing City were investigated with the symptom checklist 90 (SCL-90), self-esteem scale (SES), acceptance and action questionnaire-Ⅱ (AAQ-Ⅱ), and cognitive fusion questionnaire-fusion (CFQ-F). SPSS 22.0 software was used for statistical analysis. T test, ANOVA, correlation analysis and tests for mediation effects were conducted. Results:There were significant differences in self-esteem and mental health level among medical students in gender and different grades ( t=-2.55, P<0.05; F=6.53, P<0.05). Mental health, self-esteem and psychological flexibility of medical students were correlated in pairs ( r=-0.528-0.694, P<0.01). Psychological flexibility played a partial mediation role between self-esteem and mental health of medical students, and the mediating effect accounted for 60.03% of the total effect. Conclusion:Self-esteem can directly predict the mental health of medical students, and can also indirectly affect mental health through psychological flexibility. Medical universities should carry out psychological education and promotion work with pertinence.
