The mechanism of mandatory exercise check-in on college students' intention to use fitness apps: a complete mediation model.
Article in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Based on the Theory of Planned Behavior (TPB), this study investigates the underlying motivational mechanism linking subjective norms (SN) to the behavioral intention (BI) to use fitness applications among college students. A questionnaire survey was conducted on 387 university students in Shanghai to construct a sequential mediation model. The results reveal that while SN has a significant total effect on app usage intention, its direct effect is statistically insignificant. Crucially, the analysis confirms that the relationship between SN and BI is entirely driven by a complete serial mediation involving Self-determined Motivation (SDM) and Exercise Volume (EV). This mechanism reveals that external norms influence intention predominantly through the process of internalization mediated by SDM. The findings emphasize that the long-term efficacy of mandatory policies hinges on fostering intrinsic motivation. Therefore, higher education sports policies should shift from a purely task-driven framework to a motivation-driven approach to effectively enhance exercise quality and cultivate students’ autonomous and persistent exercise habits.
