The mechanism of physical exercise and adolescent short-form video app addiction: the chain mediating role of autonomous motivation and mental health literacy.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundIn the digital era, excessive use of short-form video applications (Apps) can exert numerous negative effects on the physical and mental health of adolescents. Physical exercise not only benefits physical health but also enhances intrinsic motivation levels and psychological regulation abilities. Therefore, this study aims to explore the association between Physical Exercise and Short-form Video App Addiction, as well as the mediating roles of Autonomous Motivation and Mental Health Literacy in the relationship between physical exercise and short-form video app addiction.
methodsThis study employed a combination of convenience sampling and stratified sampling to conduct a cross-sectional survey among 644 junior and senior high school students. The cross-sectional nature of the data limits causal inference. Measurements included the Physical Activity Rating Scale, Autonomous Motivation Scale, Mental Health Literacy Scale, and Short-form Video App Addiction Scale. Data analysis was performed using AMOS 24, SPSS 27.0, and PROCESS 4.1 for reliability and validity assessment, descriptive statistics, correlation analysis, and mediation analysis.
results(1) Physical exercise showed a statistically significant negative correlation with adolescent short-form video app addiction; (2) Both autonomous motivation and mental health literacy independently mediated the relationship between physical exercise and adolescent short-form video App addiction; (3) Autonomous motivation and mental health literacy played a chain mediating role between physical exercise and adolescent short-form video App addiction.
conclusionPhysical exercise is negatively associated with adolescent short-form video app addiction, while also positively associated with autonomous motivation and mental health literacy. High levels of autonomous motivation and mental health literacy are associated with lower levels of short-form video app addiction. Based on these association patterns, we suggest that schools and families, in holistic practices promoting adolescent health development, should emphasize the integration of physical exercise, autonomous motivation development, and mental health literacy enhancement. This comprehensive health promotion approach may provide a reference for future research exploring how to promote healthy digital media use habits among adolescents. It should be noted that the directionality of the aforementioned associations and their potential intervention effects still require further validation through longitudinal tracking or experimental studies.
