The Symptom Network Structure of Teachers' Burnout and Its Connection to Psychological Capital.

Background: Teacher burnout is characterized by emotional and physical exhaustion resulting from excessive work-related stress. Previous research based on traditional latent variable theory has revealed a significant negative relationship between TB and psychological capital (PsyCap). This study explored the complex symptoms of TB and the contact points of PsyCap in reducing TB using psychometric network analysis. Methods: A total of 3991 teachers completed the burnout subscale of the Professional Quality of Life and Psychological Capital Scale. Results: The results showed that: (a) In the TB network, the core symptoms displayed by teachers due to burnout are difficulty feeling "I am a very caring person", "I am happy", and "I am the person I always wanted to be"; (b) The TB-PsyCap network was closely connected, and the symptoms affected each other. PsyCap affected the TB network through "I feel optimistic and happy almost every day" and "I often feel that there is a future as a teacher"; (c) PsyCap's bridge symptoms had a negative impact on TB, and PsyCap may reduce TB primarily through optimistic, hopeful dimensions. Conclusion and Implications: Psychometric network analysis helps us understand the complex symptoms of TB and the contact points of PsyCap in reducing TB. This study offers valuable insights into the prevention of, and intervention in, burnout within the teaching community.

Professional Identity Makes More Work Well-Being Among In-Service Teachers: Mediating Roles of Job Crafting and Work Engagement.

Though the positive association between well-being and professional identity among employees is well-document, the internal mechanism underlying this association is known little. Guided by self-determination theory (SDT) and the job demands-resources (JD-R) model, this study examined the roles of job crafting and work engagement in mediating the association between professional identity and workplace well-being. We surveyed 2090 teachers (including Primary, Middle, and High School teachers) (M age = 39.42 years; SD = 8.72). Teachers completed a series of questionnaires, such as the Teachers' Professional Identity Scale, Employee's Workplace Well-being Scale, Job Crafting Scale, and Utrecht Work Engagement Scale. We controlled age, teaching age, and gender covariates to get conservative predictions. Multiple mediation analyses were utilized in this study to prove that: (a) professional identity was positively linked to workplace well-being; (b) both job crafting and work engagement take mediator roles in associating the relationships between professional identity and workplace well-being; and (c) a serial indirect pathway (professional identity → job crafting → work engagement → workplace well-being) emerged. These findings explore the factors that affect well-being and point to potential ways in enhancing teachers' workplace well-being even when the task is severe.

The Influence of Subjective Socioeconomic Status on Life Satisfaction: The Chain Mediating Role of Social Equity and Social Trust.

Life satisfaction is significantly influenced by social capital, a key sociological term that links people to their social surroundings. Through a survey of 17,217 Chinese residents, this study investigated the probable processes of how subjective socioeconomic status affects life satisfaction within the framework of social capital. The results indicate that there is a positive correlation between subjective socioeconomic status and life satisfaction. Subjective socioeconomic status influences citizens' life satisfaction not only through the independent mediating effects of perceived social equity and social trust, but also through the chain mediation of perceived social equity and social trust. This research advances our knowledge of the mechanisms behind the association between subjective socioeconomic status and life satisfaction. In improving citizens' life satisfaction, we should not only provide sufficient subjective socioeconomic status to improve it, but also focus on the improvement of their social equity perceptions and social trust.

How Does Shyness Affect Chinese College Students' Tendency to Mobile Phone Addiction? Testing the Mediating Roles of Social Anxiety and Self-Control.

Background and Aims: Mobile phone addiction among college students has gained considerable research attention because of its adverse effects on their health and academic performance. However, little is known about the mechanisms underlying the relationship between shyness and mobile phone addiction among college students. Methods: Four questionnaires were used to examine whether mobile phone addiction tendency was predicted by shyness and the mediating roles of social anxiety and self-control among 3,189 Chinese college students. Correlation and mediation analyses were conducted using Hayes PROCESS. Results: The results showed that (1) social anxiety (indirect effect = 0.22, 95% CI = 0.18-0.26) and self-control (indirect effect = 0.23, 95% CI = 0.21-0.25) played a partial mediating role in the relationship between shyness and mobile phone addiction tendency; (2) social anxiety and self-control also mediated the link between shyness and mobile phone addiction tendency sequentially (indirect effect = 0.10, 95% CI = 0.09 to 0.12). Conclusion: These results suggest that mobile phone addiction among shy college students could be eliminated by alleviating social anxiety and strengthening self-control.

How Is Professional Identity Associated with Teacher Career Satisfaction? A Cross-Sectional Design to Test the Multiple Mediating Roles of Psychological Empowerment and Work Engagement.

(1) Purpose: Previous studies investigated the positive relationship between professional identity and career satisfaction in teachers, but the underlying reasons were not explored. Therefore, the present study explores the mediating effects of two variables, namely, psychological empowerment and work engagement on the relationship between professional identity and career satisfaction. (2) Method: The present study used the professional identity scale, psychological empowerment scale, Utrecht Work Engagement scale and career satisfaction scale to investigate 2104 teachers (Mage = 39.50 years, SD = 8.74) in a province in China. The demographic variables (e.g., gender, age, teaching age) were controlled as covariates to conduct conservative predictions. (3) Result: (a) professional identity is positively related to career satisfaction; (b) psychological empowerment and career satisfaction play parallel mediator roles between professional identity and career satisfaction; (c) psychological empowerment and career satisfaction play serial mediator roles between professional identity and career satisfaction. (4) Limitations: Data were collected by participant self-report. This method may lead to recall bias. Further, we adopted a cross-sectional rather than experimental or longitudinal design, thus precluding causal conclusions. Lastly, it would be useful to validate our findings with a national sample. (5) Conclusions: The present study indicates that the relationship between professional identity is positively associated with teacher career satisfaction. More importantly, professional identity can indirectly make an impact on teacher career satisfaction through the single mediating effects of psychological empowerment and work engagement, and the chain mediating effect, by improving the level of psychological empowerment, and thereby increasing work engagement.

The influence of alexithymia on problematic mobile phone use among Chinese adolescent students: Multiple mediating roles of social interaction anxiousness and core self-evaluations.

BACKGROUND: Alexithymia can lead to problematic mobile phone use (PMPU). However, the underlying mechanisms remain unclear. METHODS: Drawing on the Interaction of Person-Affect-Cognition-Execution model, the present study tests the mediating effects (parallel and serial) of social interaction anxiety (SIA) and core self-evaluations (CSE) on the relationship between alexithymia and PMPU. We obtained 1267 valid responses from adolescent students (mean age, 20.36, standard deviation, 0.97) from southeast China who completed the Mobile Phone Addiction Index, Toronto Alexithymia-20 Scale, Social Interaction Anxiousness Scale, and Core Self-Evaluation Inventory. RESULTS: After controlling for demographic variables (i.e., gender) as covariates, the results revealed that: (1) alexithymia had a positive predictive effect on PMPU in adolescent students; (2) SIA and CSE mediated the association between alexithymia and PMPU; and (3) a series of indirect pathways (i.e., from alexithymia to PMPU via SIA and CSE) were detected. Thus, alexithymia can directly affect (parallel mediation) PMPU by increasing SIA and lowering CSE simultaneously. However, alexithymia can also indirectly affect (serial mediation) PMPU by increasing the level of SIA by decreasing CSE. LIMITATIONS: Data were collected by participant self-report. This method may lead to recall bias. Further, we adopted a cross-sectional rather than an experimental design, thus precluding causal conclusions. Lastly, it would be useful to validate our findings with other age groups outside southeast China. CONCLUSIONS: The current study findings are conducive to understanding the relationship between alexithymia and PMPU and inspire the prevention and intervention of PMPU.

Moral Threshold Model is Universal? Initial Evidence from China's Collectivist Culture.

PURPOSE: People choose actions that maintain their moral self-regard. This paper explains how one's moral actions influence moral self-regard. The moral threshold model (MTM) has been proposed by scholars and tested using a limited sample. However, whether the MTM is universally applicable among people is still unknown. PARTICIPANTS AND METHODS: Our sample comprised 1761 individuals living in China, a collectivist culture, who were recruited to test the two main hypotheses of the MTM. Participants engaged in a hypothetical investment task. RESULTS: 1) When the beneficiary was a prosocial cause, participants showed stronger preferences for smaller guaranteed positive payouts over larger uncertain ones; 2) as compared to making decisions for charities, when a participant made decisions exclusively for themselves, the maximum potential benefit was more likely to influence participant behavior. CONCLUSION: The current study provides initial evidence for the validity of using the worst outcome avoidance (WOA) hypothesis of MTM among members of China's collectivist culture, indicating that the WOA hypothesis of MTM may have universal application.

Why are Individuals with Alexithymia Symptoms More Likely to Have Mobile Phone Addiction? The Multiple Mediating Roles of Social Interaction Anxiousness and Boredom Proneness.

PURPOSE: Previous studies have investigated the relationship between alexithymia and problematic mobile phone use (PMPU). However, yet gaps in identifying the internal mechanisms of this relationship remain. Hence, based on the Interaction of Person-Affect-Cognition-Execution model, the current research examined the mediating roles of college students' social interaction anxiousness (SIA) and boredom proneness (BPS) in the relationship between alexithymia and PMPU. METHODS: A total of 1300 college students (M age = 20.36 years, SD = 0.97) were recruited from two universities in the southeast of China to complete a series of questionnaires, including the Toronto alexithymia scale, SIA scale, BPS scale, and mobile phone addiction index questionnaire. In order to conduct conservative predictions, the demographic variables (ie, gender) were controlled as covariates. RESULTS: The results of multiple mediation analysis showed that (1) alexithymia was positively linked with PMPU; (2) both SIA and BPS mediated the link between alexithymia and PMPU; and (3) a serial indirect pathway emerged (ie, alexithymia → SIA → BPS → PMPU). CONCLUSION: These findings indicated that alexithymia could influence PMPU in a simple indirect way (parallel mediation) and in a complex indirect way (serial mediation). Besides, these findings provide some insights into the prevention and intervention of PMPU.

Cooperation with partners of differing social experience: An fNIRS-based hyperscanning study.

Previous studies have shown the brain synchronization of all team members while completing a collaborative task. Moreover, this effect is influenced by a team's compositional elements, such as gender (opposite or same) or relationships (i.e., friends, lovers, or strangers) among team members. However, whether interpersonal brain synchronization (IBS) is affected by team members' experience, as well as the temporal dynamics of such brain synchronization, remains to be investigated. In the current study, we combined behavioral methods and functional near-infrared spectroscopy-based hyperscanning to examine the effect of member experience on team cooperation by an adopted continuous joint drawing task with 21 student-student dyads (S-S dyads) and 22 teacher-student dyads (T-S dyads). The results revealed that team members with differing experiences (T-S dyads) perform better than those with similar ones (S-S dyads). Moreover, we observed IBS in the left frontopolar region (channel 11). However, we did not observe significant changes of the task-related IBS across time. Besides, IBS was negatively correlated with the participants' behavioral performance. Our findings demonstrate the importance of social experience in teamwork in the real world and suggest a possible mechanism for cooperation from a temporal and spatial perspective.

Loneliness and Mobile Phone Addiction Among Chinese College Students: The Mediating Roles of Boredom Proneness and Self-Control.

INTRODUCTION: Mobile phones bring convenience to people's lives, but also affect their physical and mental health (especially in college students). Previous studies have revealed that mobile phone addiction is positively related to loneliness. This study further explored the mediating effects of boredom proneness and self-control on the relationship between loneliness and mobile phone addiction. METHODS: A cross-sectional design was conducted in the present study. The investigation employed the Chinese version of the UCLA Loneliness Self-report Scale, Boredom Proneness Scale-Short Form, the Chinese version of the Self-control scale, and the Mobile Phone Addiction Index. Out of 1122 college students, 1078 completed the questionnaire survey and became our final subjects. PROCESS macro of SPSS 21 was used to conduct explore the mediating roles of boredom proneness and self-control in the relationship between loneliness and mobile phone addiction. RESULTS: Loneliness, boredom proneness, and mobile phone addiction were significantly and positively correlated with each other, as well as significantly negatively correlated with self-control. Boredom proneness and self-control, when operating in parallel, partially mediated the relationship between loneliness and mobile phone addiction. By contrast, when occurring sequentially, they fully mediated the relationship between loneliness and mobile phone addiction. CONCLUSION: Mobile phone addiction among lonely college students can be eliminated by exercising self-control and alleviating boredom proneness.

Activation of MnFe2O4 by sulfite for fast and efficient removal of arsenic(III) at circumneutral pH: Involvement of Mn(III).

As(III) oxidation to As(V) is deemed necessary for better arsenic removal, and separation is still the optimal approach for water remediation from As(III). Herein, sulfite (SIV) was adopted to activate MnFe2O4 for simultaneous oxidation and adsorption of As(III) in neutral water. The As(III) removal was more efficient than a peroxidation of As(III) followed by adsorption. The adsorption capacity of MnFe2O4/S(IV) for As(III) (26.257 mg g-1) was much higher than those of MnFe2O4 alone for As(III) (9.491 mg g-1) and As(V) (9.142 mg g-1). The mechanistic study corroborated that intermediate Mn(III) was the dominant oxidant responsible for rapid oxidation of As(III), and the dual roles of S(IV) as a complexing ligand and a precursor of oxysulfur radicals accelerated the redox cycle of Mn(II)/Mn(III). Moreover, S(IV) enhanced arsenic adsorption by driving more production of monodentate complexes. As(III) can be effectively removed over a wide range of temperatures (283.15-313.15 K) and pH (3-10) with the optimal pH of 7. The effect of coexisting ions and reusability of MnFe2O4 were also investigated. Especially, the superior performance of MnFe2O4/S(IV) for As(III) removal in various water matrixes may help develop new removal technologies based on active Mn(III) for the water decontamination from As(III).

Self-other overlap and interpersonal neural synchronization serially mediate the effect of behavioral synchronization on prosociality.

Behavioral synchronization has been found to facilitate social bonding and prosociality but the neural mechanisms underlying such effects are not well understood. In the current study, 60 dyads were hyperscanned using functional near-infrared spectroscopy while they performed either a synchronous key-pressing task or a control task. After the task, they were asked to perform the dictator game to assess their prosocial behavior. We also measured three potential mediating variables: self-other overlap, perceived similarity and interpersonal neural synchronization. Results showed that dyads in the synchronization group were higher in behavioral synchronization, interpersonal neural synchronization (INS) at the right dorsolateral prefrontal cortex, self-other overlap, perceived similarity and prosociality than those in the control group. INS was significantly associated with prosocial behaviors and self-other overlap. After testing four meditation models, we found that self-other overlap and INS played a serial mediation role in the effect of behavioral synchronization on prosociality. These results contribute to our understanding of the neural and cognitive mechanisms underlying the effect of behavioral synchronization on prosocial behavior.

Behavioral and brain synchronization differences between expert and novice teachers when collaborating with students.

Differences in behavior and neural mechanisms between expert and novice teachers when collaborating with students are poorly understood. This study investigated whether expert teachers do better in collaborating with students than novice teachers and explored the neural basis of such differences. Novice teacher and student (NT-S) dyads and expert teacher and student (ET-S) dyads were recruited to complete an interactive task consisting of a cooperation and an independent condition. During the experiment, neural activity in the prefrontal cortex of the participants was recorded with functional near-infrared spectroscopy. The results show higher accuracy for the ET-S dyads than the NT-S dyads in the cooperation condition; however, no difference was found in the independent condition. Increased interpersonal brain synchronization (IBS) was detected in the left dorsolateral prefrontal cortex of participants in ET-S dyads, but not in NT-S dyads in the cooperation condition. Moreover, an interaction effect of dyad type and conditions on IBS was observed, revealing IBS was stronger in ET-S dyads than in NT-S dyads. In ET-S dyads, IBS was positively correlated with the teachers' perspective-taking ability and accuracy. These findings suggest that expert teachers collaborate better with students than novice teachers, and IBS might be the neural marker for this difference.

Accurate empathy of romantic partners increases pain ratings but promotes recovery.

BACKGROUND: Perceived empathy is a commonly used strategy to cope with pain and is crucial for maintaining intimacy in dyadic relationships. MATERIALS AND METHODS: This study used the cold pressor test to investigate how perceived empathy and relationship type interact with the subjective perception of pain and objective measures of recovery time, using heart rate as an index. One hundred and ninety participants were recruited, including 49 friend dyads and 46 romantic partner dyads. Perceived empathy was manipulated by adopting three levels as the experimental conditions: high, accurate, and low. RESULTS: In the subjective perception stage, the results showed a significant interaction of relationship type and empathy with pain reporting, indicating that romantic partners reported more pain than friends under the accurate empathy condition. There were no differences between the two groups in the high and low perceived empathy conditions. In the self-recovery stage, the results showed that romantic partners had less pain tolerance than friends in all three perceived empathy conditions. On the other hand, romantic partners recovered faster than friends under the accurate empathy condition, but not under the high and low perceived empathy conditions. CONCLUSION: These results suggest that perceived accurate empathy is necessary for romantic relationships when coping with pain. The findings deepen our understanding of the mechanism of perceived empathy, and the ways in which it modulates psychological and physiological responses in a social context.
