Exploring the relationship between social exclusion and smartphone addiction: The mediating roles of loneliness and self-control

Previous studies have identified many antecedents of smartphone addiction. However, social exclusion as a risk factor for smartphone addiction has not been widely studied, and little is known concerning the psychological mechanism underlying this association. The present study tested the influence of social exclusion on smartphone addiction as well as the mediating roles of loneliness and self-control in this relationship. An online survey was conducted, and the sample consisted of 573 university students (323 females). The results revealed that (1) social exclusion was a positive predictor of smartphone addiction; (2) loneliness and self-control separately mediated the association between social exclusion and smartphone addiction; and (3) loneliness and self-control sequentially mediated the relation between social exclusion and smartphone addiction. Possible explanations were discussed. The findings of the current study would contribute to understanding the relationships between these study variables as well as the psychological mechanisms underlying these associations.

Peer Phubbing and Social Networking Site Addiction: The Mediating Role of Social Anxiety and the Moderating Role of Family Financial Difficulty

A growing body of research has pinpointed the consequences as well as mechanisms of phubbing. However, few studies have explored the relationship between peer phubbing and social networking site addiction. Based on the self-determination theory, the exclusion theory of anxiety, the social compensation model, and the reserve capacity model, the present study examined whether peer phubbing was positively related to social networking site addiction among undergraduates, whether social anxiety mediated the relationship, and whether this mediating process was moderated by family financial difficulty. Our theoretical model was tested using the data collected from 1,401 Chinese undergraduates (M_age = 18.83 years, standard deviation = 0.93). The participants completed anonymous questionnaires that assessed their peer phubbing, social anxiety, social networking site addiction, and family financial difficulty. The correlation analysis indicated that peer phubbing was positively associated with social networking site addiction. The testing for moderated mediation further revealed that social anxiety partially mediated the association between peer phubbing and social networking site addiction, with family financial difficulty moderating the first stage. To be specific, the indirect association between peer phubbing and social networking site addiction via social anxiety was stronger for undergraduates in high family financial difficulty. The results from this study extend research on the potential consequences of phubbing as well as highlight the significance of uncovering the underlying mechanisms.

An experimental investigation of peer rejection and social anxiety on alcohol and cannabis use willingness: Accounting for social contexts and use cues in the laboratory

OBJECTIVE

Evidence suggests that social anxiety (SA) is a risk factor for problematic alcohol and cannabis use, particularly during states of social stress. Unfortunately, laboratory studies to date have overlooked decision-making mechanisms (e.g., use willingness) and contextual features of commonly used social stress tasks that may clarify what is driving these links. The current study begins to address this gap by testing the effects of SA and laboratory-induced peer rejection on acute alcohol and cannabis use willingness within a simulated party setting.

METHOD

80 emerging adults (18-25 years; 70% women) endorsing lifetime alcohol and cannabis use were randomly assigned to experience rejection or neutral social cues. They rated their willingness to use alcohol and cannabis before and after cue exposure within the simulated party. A hierarchical regression tested the main and interaction effects of SA symptoms and experimental condition (Rejection vs. Neutral) on alcohol and cannabis use willingness, controlling for past-year use frequency and willingness to accept any offers (e.g., food and nonalcoholic drinks).

RESULTS

There were statistically significant main (but not interaction) effects of SA and experimental condition on cannabis use willingness. Higher SA and Rejection exposure were each associated with greater cannabis use willingness. There were neither main nor interaction effects on alcohol willingness.

CONCLUSIONS

Results suggest that elevated SA increases cannabis use willingness across social contexts, regardless of Rejection exposure, while Rejection exposure increases use willingness similarly across levels of SA. Together, findings reinforce the need to consider social-contextual factors and polysubstance use in laboratory settings. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
