Background: Several studies have explored the positive relationship between socioeconomic status and sense of gain. However, little is known about the underlying mechanism between them. This study aimed to explore whether community identity had a mediating role between them among Chinese adults. Methods: Data were collected from a nationally representative samples of 28,300 adults from the China Family Panel Studies. Socioeconomic status was assessed using individuals' income and social status. Community identity was assessed through evaluation of the community's public facilities, surrounding environment, surrounding security, neighborhood relationship, neighborhood assistance and feelings towards the community. Sense of gain was measured by evaluation of environmental conservation, gap between the rich and the poor, employment, education, medical treatment, housing, social security, and government corruption. Pearson's correlation was used to examine the associations between major variables. Mediation analyses were performed to explore the mediating role of community identity between socioeconomic status and sense of gain. Results: Socioeconomic status was positively associated with sense of gain. Community identity played a mediating role between socioeconomic status and sense of gain. Conclusion: Community identity mediated the relationship between socioeconomic status and sense of gain. Promoting the mobility of socioeconomic status and actively intervening in community identity are conducive to improve sense of gain. political sense of gain, security sense of gain and self-realization sense of gain. Studies have reported there is positive associations between sense of gain and cognition and psychological health, such as well-being [5,6], government trust [2,7], andperception of social stability [8]. Therefore, exploring how to enhance individuals' sense of gain contributes to national stability and psychological health.Socioeconomic status is a social classification used to reflect the relative position of an individual in the social hierarchy, which is composed of objective material resources (often measured by income, education level, and occupational status), and subjectively perceived social status [9,10]. Socioeconomic status affects every aspects of an individual's life, including sense of gain. For example, Wang [11] found that the increase of socioeconomic status was often accompanied by the improvement of sense of gain. Specifically, upper-middle status or upper-status residents have higher sense of gain than lower status residents. Wang, Tan, and Fu [12] also found that socioeconomic status had a significant and positive effect on sense of gain. Tan, Wang and Zhang [13] found significant differences in sense of gain among different educational levels and monthly income. Dou, Dong and Tan [14] found that there were positive relationship between subjective and objective socioeconomic status and sense of gain. There are also studies that provide indirect evidence for the relationship between socioec...

Socioeconomic status is related to altruistic behaviour, but the link between them remains controversial. The present study explored the link between socioeconomic status and altruistic behaviour, as well as the psychological mechanism between them. We recruited 1,052 residents from 34 provinces in China to investigate the relationship between socioeconomic status and altruistic behaviour and the mediating mechanism. Results showed that objective socioeconomic status was positively related to altruistic behaviour. Subjective socioeconomic status was positively associated with community identity and altruistic behaviour. Community identity mediated the relationship between subjective socioeconomic status and altruistic behaviour. The findings suggest that enhancing individuals' community identity or subjective status perception can effectively increase their altruistic behaviour.

China was a major hotspot during the beginning of the COVID-19 pandemic. Several studies have reported changes in residents' eating behaviors and appetite during city wide lockdowns and home confinements. However, few have investigated how neuroticism interacts with the impact of COVID-19 to influence eating behaviors during city lockdowns. Thus, the current study aims to establish a pathway model to understand social media exposure, negative affect, neuroticism, and their interaction with eating behaviors during the COVID-19 lockdowns. We present data from 1,128 participants (Mage = 24.34 ± 10.48 years) who completed an online survey between February 17 and 27, 2020.

Background Studies have explored the relationship between social class and health for decades. However, the underlying mechanism between the two remains not fully understood. This study aimed to explore whether health self-management had a mediating role between social class and health under the framework of Socio-cultural Self Model. Methods 663 adults, randomly sampled from six communities in Southwest China, completed the survey for this study. Social class was assessed using individuals’ income, education, occupation. Health self-management was assessed through evaluation of the health self-management behavior, health self-management cognition, health self-management environment. Physical health and mental health were measured by the Chinese version of Short-Form (36-item) Health Survey, which contains Physical Functioning, Role-Physical, Role-Emotional, Vitality, Mental Health, Social Function, Bodily Pain and General Health. Pearson’s correlation was used to examine the associations between major variables. Mediation analyses were performed to explore the mediating role of health self-management. Results Social class positively predicted self-rated health. The lower the social class, the lower the self-reported physical and mental health. Health self-management partially mediated the relationship between social class and self-rated health. That is, the health self-management ability of the lower class, such as access to healthy and nutritious food and evaluate their own health status, is worse than that of the higher class, which leads to physical and mental health inequality between the high and the low classes. Conclusion Health self-management mediated the relationship between social class and health. Promoting health self-management abilities are conducive to improving both physical and mental health.
