Positive perfectionism and exercise persistence in Chinese adolescents: a moderated serial mediation model of self-efficacy, autonomous motivation, and perceived social support.
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
backgroundTo clarify whether positive perfectionism is associated with exercise persistence in adolescents and to test a moderated serial mediation model.
methodsA cross-sectional school-based survey was conducted among 1,032 students (12–18 years) in Dalian, China. Participants reported positive perfectionism, self-efficacy, exercise-related autonomous motivation, perceived social support, and exercise persistence. Regression with bootstrapping tested mediation and moderated mediation.
resultsPositive perfectionism was positively associated with exercise persistence. This association was statistically mediated by self-efficacy and autonomous motivation in sequence. Perceived social support moderated the autonomous motivation–exercise persistence link, such that the serial indirect association was stronger at higher levels of perceived social support.
conclusionsPositive perfectionism was associated with greater exercise persistence via higher self-efficacy and autonomous motivation, and this indirect association was stronger when perceived social support was higher. Longitudinal or experimental studies are needed to clarify causal directions.
