How Psychological Capital and Academic Burnout Shape Short-Video Addiction: A Latent Profile Analysis of Heterogeneity.
Article in Brain and behavior, 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
backgroundShort-video addiction among adolescents is a growing concern, yet existing research has largely adopted variable-centered approaches that assume homogeneity.
aimThis study aimed to identify distinct stress-resource profiles based on psychological capital and academic burnout and to examine differences in self-control and short-video addiction across profiles, along with predictors of profile membership and the interactive effect of psychological capital and academic burnout on addiction.
methodsA cross-sectional survey was conducted among 1719 Chinese middle school students (53.1% male). Latent profile analysis (LPA) was used to identify profiles. Differences in self-control and addiction were tested with ANOVA, predictors with multinomial logistic regression, and the interaction with multiple linear regression.
resultsThree profiles emerged: Adaptive (57.6%), Maladaptive (14.5%), and Advantaged (27.9%). The Advantaged profile showed the highest self-control and the lowest addiction, whereas the Maladaptive profile showed the lowest self-control. Post-hoc tests revealed no significant difference in addiction between the Adaptive and Maladaptive profiles (p = 0.351), but both showed significantly higher addiction than the Advantaged profile. Female adolescents were less likely to belong to the Advantaged profile (OR = 0.75); a higher grade reduced odds of Maladaptive (OR = 0.86) and Advantaged (OR = 0.82) profiles; and left-behind status increased odds of the Advantaged profile (OR = 1.90). Psychological capital moderated the burnout-addiction relationship (B = 0.035, p = 0.005); notably, the association strengthened as psychological capital increased, challenging the view of psychological capital as universally protective.
conclusionAdolescents exhibit heterogeneous stress-resource profiles with distinct patterns of self-control and addiction. Person-centered approaches can inform tailored interventions, particularly by addressing both resource deficits and the complex role of psychological capital in coping processes.
