Although prior studies have to some extent clarified the mechanism underlying the development of social media burnout, the present study contributes to the literature by showing how social media addiction contributes to this phenomenon. Chinese university students (N = 519) completed self-report questionnaires on social media addiction, social media burnout, envy, and social media use anxiety. The results showed that addiction, envy, and social media use anxiety were all significant predictors of burnout. Moreover, envy and social media use anxiety mediated the relationship between social media addiction and burnout, both in parallel and as a pair in series. Considering the negative effect of social media burnout such as depression, the findings may provide new path to understand the detrimental of excessive use of social media toward corresponding psychological outcomes.

Although prior research has found that receipt of social support through social networking sites is a significant predictor of Facebook addiction, the mechanism underlying this association remains unclear. This study aimed to explore the mediating roles of fear of missing out and problematic smartphone use in the relationship between these two variables in a Chinese context. Four hundred and sixty-five undergraduates participated in this study by completing measures of support received through online social networking sites, fear of missing out, problematic smartphone use, and addiction to Chinese social media. The results showed that fear of missing out and problematic smartphone use mediated the relationship between support through online social networking sites and addiction to such sites, both in series and in parallel. This might be among the first studies to elucidate the mechanism underlying the development of social media addiction from the perspective of online support. Although the cross-sectional design employed has several limitations, these findings offer a potential avenue of research in the development of strategies for the prevention of addiction to social networking sites and interventions for treating this affliction.

Accumulating evidence has shown that social media addiction is a growing problem in China, especially among emerging adults. Nonetheless, the absence of a psychometrically sound measuring tool obstructs further progress in this field. Therefore, we examined the properties of a newly developed social media addiction scale among a sample of 619 college students. An exploratory factor analysis revealed that the scale had six factors: preference for online social interaction, mood alteration, negative consequence and continued use, compulsive use and withdrawal, salience, and relapse, which explained 63.83% of the total variance. Cronbach's alpha and half-split coefficient of the whole scale were 0.937 and 0.879, respectively. A confirmatory factor analysis indicated that the six-factor model was a good fit to the data. Moreover, the social media addiction scores were positively correlated with smartphone addiction, pathological Internet use, and narcissism, but negatively associated with self-esteem. Our study suggests that the newly developed social media addiction scale could be used as an effective tool to assess social media addiction among emerging adults in China. [ABSTRACT FROM AUTHOR]
