BACKGROUND: While prior studies have established a close association between the use of social network sites (SNSs) and materialistic values, there is limited understanding of the mediating and moderating mechanisms related to important self-related processes, such as self-control and self-acceptance. This paper explores whether and how these factors play a role in comprehending online behavior. One could state that frequent SNS use may pose a risk of virtual addiction, may be related to decreased self-control capacity, and may increase attention to material information on SNS, thereby making it more likely that users affiliate with behaviors associated with materialistic values. In contrast, self-acceptance, as a stable self-process indicating a genuine alignment with one\'s true self and the ability to make decisions based on inner needs, may be related with reduced engagement in complex information on SNSs. Consequently, this could serve as a buffer against excessive SNS use and its potential associations with issues of self-control and materialistic values.
METHODS: A total of 706 Chinese college students were surveyed in a cross-sectional study. They completed self-report questionnaires including the WeChat use intensity scale, the Material Value Scale, the Trait Self-control Scale, and the Self-acceptance Questionnaire. A moderated mediation model was examined to test predictions.
RESULTS: SNS use intensity was positively associated with materialistic values, and self-control partially mediated this association. That is, higher intensity SNS users are more likely lower in self-control, which relates to stronger materialistic values. In addition, the indirect effect through self-control was moderated by self-acceptance, such that this indirect effect was significant only for individuals with low levels of self-acceptance.
CONCLUSIONS: This study reveals that self-acceptance may be a protective factor that helps to mitigate excessive SNS use and its potential effects on self-control and materialistic values. It further suggests that psychological interventions targeting the enhancement of self-acceptance and self-control could hold promise in alleviating the negative association between SNS use and materialistic values.

This meta-analysis examines the relationship between materialism (materialistic values and extrinsic aspirations) and subjective wellbeing in the Chinese population. Fifty-six relevant studies covering the period from 1998 to 2022 were included in the meta-analysis. Fifty-eight independent effect sizes from a total of 52,368 participants were obtained to calculate the mean effect sizes. Materialistic values correlated with significantly lower subjective wellbeing (r = -0.205), while the mean effect size for extrinsic aspirations was found to be not significant (r = -0.048). The effect sizes varied across different types of wellbeing outcomes (materialistic values: rs = -0.095 to -0.202; extrinsic aspirations: rs = 0.066 to -0.125). The associations were also moderated by certain demographic factors (age and gender), methodological factors (study design and scoring method), publication features (type of publication and publication year), and economic indicators (economic growth and wealth inequality). We discuss our limitations and the implications for future research.

We designed three studies to explore the effect of materialistic values on pro-environmental behavior among youth and the mediated role of nature connectedness between materialistic values and pro-environmental behavior. Through a self-report questionnaire survey (Study 1) and an experimental manipulation of materialistic values (Study 2), we found that materialistic values negatively predicted pro-environmental behavior, and that nature connectedness played a mediating role. Further, we used natural contact strategies to control the level of nature connectedness, and found that the negative impact of high materialistic values on pro-environment behavior decreased with the increase of nature connectedness, further supporting the mediating role of nature connectedness (Study 3). These results may contribute to the design of strategies that effectively mitigate the negative effects of materialistic values on pro-environmental behavior.

Cars represent a valuable real asset that most individuals use on a daily basis. Although cars are a form of material prosperity like income and other forms of wealth, the link between cars and subjective well-being (SWB) is barely covered in the existing literature. Furthermore, few existing contributions are scattered across specific cultural contexts. Here, we analyze the relationship between cars and the SWB of seniors in different European countries using the SHARE dataset. We construct multilevel and fixed-effect models to explore the extent of economic, infrastructural, and cultural factors and how they can explain this relationship. The results show that the value of the car is, among all wealth components (houses, bank account, bonds, stocks, mutual funds, debts and mortgages), the form of wealth most related to life satisfaction. In addition, cars matter less (a) in affluent societies, (b) where rail infrastructure is more developed, and (c) where people hold fewer materialistic values. We discuss these results in the framework of the functional and positional value of cars, i.e., respectively, the value derived from it regardless of others and the value derived from it vis-à-vis others.

Individuals with high levels of externally contingent self-worth tend to base their self-esteem on factors such as appearance, competitive success, and others\' approval. Such tendencies might also elevate people\'s focus on material possessions. However, cultural moderation of these associations has yet to be explored. A cross-cultural survey among Chinese and Dutch college students examined the link between externally-based contingent self-worth and materialistic values, as well as the mediating roles of need to belong and need for self-enhancement. An initial multi-group path analysis indicated a stronger link between externally contingent self-worth and materialism for Chinese students than for Dutch students. For both Chinese and Dutch students, externally contingent self-worth was positively related to materialistic values, need to belong, and need for self-enhancement. Need to belong and need for self-enhancement were positively linked with materialism, and need to belong and need for self-enhancement mediated the link between externally contingent self-worth and materialism. Though the indirect effect via self-enhancement was somewhat stronger among Chinese participants, this research demonstrates that people\'s externally contingent self-worth might be a factor predicting materialism across cultures, with need to belong and need for self-enhancement playing similar roles as underlying processes in different societies.

Studies consistently show that materialism might be a strategy people use to cope with low self-esteem. This link might differ among people holding different definitions of the \"self\" in terms of their relationships with others, however. This research examined the link between self-esteem and materialistic values from the perspective of how people define the self, or their self-construal. In three studies, we explored the moderating role of self-construal in the link between Chinese participants\' self-esteem and materialistic values. Through a self-report survey (Study 1, N = 422), experimental manipulation of self-construal (Study 2, N = 151), and experimental manipulation of both self-esteem and self-construal (Study 3, N = 123), results indicated that self-esteem and self-construal interacted in predicting materialistic values. Specifically, self-esteem negatively predicted materialistic values when interdependent self-construal was low, but not when it was high. We suggest that individuals\' pursuit of materialism under conditions of low self-esteem might depend on how they define the \"self.\"
