Smartphone addiction affects life satisfaction among Chinese university students: the serial mediation effects of social anxiety for social media users and mental well-being.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLife satisfaction is an essential component that enables individuals to discover meaning in their lives and attain cognitive well-being. Life satisfaction is typically associated with aspects such as meaningfulness, fulfilment, and happiness. To gain a deeper understanding of university students' life satisfaction, this study explores the influence of psychological mechanisms of social anxiety for social media users and mental well-being from the perspective of smartphone addiction. Specifically, it aims to examine the effect of smartphone addiction on life satisfaction among university students in China, with social anxiety for social media users and mental well-being acting as serial mediators within the proposed research model.
methodsThe respondent in this study was analyzed using a non-probability cross-sectional survey approach. Questionnaires were distributed to university students in China, which include the regions of Northeast China, North China, Northwest China, Central China, South China, East China, and Southwest China. Eventually, 4,159 university students were identified as usable data for analysis. The data were analyzed using IBM SPSS 29 and SmartPLS 4.1.1.4 software, specifically adopting the partial least squares-structural equation modelling (PLS-SEM) approach.
resultsThe results indicated that, for the direct effect hypotheses, smartphone addiction was not significantly associated with life satisfaction. However, smartphone addiction was positively and significantly associated with social anxiety related to social media use, and negatively and significantly associated with mental well-being. Social anxiety for social media users was negatively and significantly associated with both mental well-being and life satisfaction. Mental well-being, in turn, was positively and significantly associated with life satisfaction. Regarding the mediation and serial mediation hypotheses, the results showed that social anxiety for social media users and mental well-being both had significant negative indirect associations with the relationship between smartphone addiction and life satisfaction. Additionally, the serial mediation pathway through social anxiety and mental well-being was also statistically significant.
conclusionsThis study contributes to a better understanding of the associations among smartphone addiction, social anxiety, mental well-being, and life satisfaction among university students. While causal interpretations cannot be drawn due to the cross-sectional design, the findings highlight potential psychological pathways that may underlie the link between intensive smartphone use and reduced life satisfaction. These insights may inform the development of future university-based interventions that aim to address smartphone-related difficulties and promote student well-being. As digital engagement continues to grow, further longitudinal research is recommended to clarify the directionality of these associations and to support the design of effective strategies for enhancing university students' quality of life.
