Storing, Not Reading: Investigating the Link Between Upward Social Comparison via Social Media and Digital Hoarding Behavior in Chinese Youth

Background

Digital hoarding has emerged as a pervasive psychological phenomenon and behavioral challenge among contemporary youth. This study focused on exploring the relationship between upward social comparison via social media, fear of missing out (FoMO), mindfulness, digital hoarding behavior, and its underlying mechanisms.

Methods

A total of 927 young people participated in this cross-sectional study. Research instruments included the Social Comparison Scale, the Fear of Missing Out Scale, the Mindfulness Measure, and the Digital Hoarding Behavior Questionnaire. The data analysis comprised descriptive statistics and correlation analyses. Advanced analyses were conducted using Model 4 for mediation and Model 8 for moderation from the PROCESS macro.

Results

(1) Upward social comparison via social media was a strong predictor of digital hoarding behavior, even after controlling for variables such as gender, age, and education. (2) FoMO mediated the relationship between upward social comparison via social media and digital hoarding. (3) Mindfulness moderated both the direct effect of upward social comparison via social media on digital hoarding and the first segment of the mediating role of FoMO.

Discussion

The study further clarified the antecedents and psychological mechanisms that drive digital hoarding behavior. The findings contribute new perspectives for understanding the emerging concept of digital hoarding, while providing empirical evidence and valuable guidance for encouraging young adults to use social media responsibly and reduce impulsive hoarding tendencies.

Relationship between fruit and vegetable consumption and internet addiction with insomnia and depression as multiple mediators during the COVID-19 pandemic: a three-wave longitudinal study in Chinese college students

BACKGROUND

The relationships between fruit and vegetable consumption (FV) and Internet addiction (IA) in college students still remained unknown together with the internal mechanisms. Given the limitations of previous cross-sectional design, longitudinal research was necessary to be conducted to explore more precise correlations. Using the three-wave data in a longitudinal design, this study aimed to explore the association between FV and IA among Chinese college students and potential multiple mediators of insomnia and depression during the COVID-19 pandemic.

METHODS

A total of 579 college students were recruited during three waves (T1: August 2020; T2: November 2020; T3: February 2021). FV (T1), insomnia (T2), depression (T2) and IA (T3) symptoms were reported. The descriptive statistics of the sociodemographic characteristics and correlation analyses of the study variables were calculated. The significance of the mediation effects was measured conducting a bootstrap method with SPSS PROCESS macro.

RESULTS

FV was negatively correlated with IA, and lower FV predicted higher risk of IA. Depression mediated the association between FV and subsequent IA. Insomnia and depression were multiple mediators, which in turn mediated the links between FV and subsequent IA.

CONCLUSIONS

The three-wave longitudinal study has revealed that FV had indirect effects on IA through individual mediating factor of depression and multiple mediating roles of insomnia and depression sequentially. The policy makers, educators and researchers should pay attention to the impact of the interventions from healthy diet, in order to optimize the coping strategies for preventing college students from IA.
