How balanced time perspective affects short-video addiction: a chain mediation model based on trait anxiety and ego depletion.
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
backgroundPrevious studies have identified balanced time perspective as a protective factor against short-video addiction among adolescents. However, the underlying psychological mechanisms linking these two constructs remain insufficiently explored. Guided by the cognition-emotion-behavior theory, this study aimed to investigate the mediating mechanisms through which balanced time perspective influences short-video addiction.
methodsTwo studies were conducted: a cross-sectional study (Study 1, N = 689; 54.3% male, mean age = 14.40 years, SD = 2.11) and a two-wave longitudinal study (Study 2, N = 470; 50.0% male, mean age = 14.23 years, SD = 1.01). In Study 1, a multiple mediation model was employed to examine the mediating role of trait anxiety and ego depletion in the relationship between balanced time perspective and short-video addiction. In Study 2, a cross-lagged model was used to verify the longitudinal mediating chain involving balanced time perspective, trait anxiety, ego depletion, and short-video addiction.
resultsFindings from both studies consistently supported the proposed hypotheses. Study 1 found a serial mediation effect of trait anxiety and ego depletion (total indirect effect = -0.2159, 95% CI [-0.2771, -0.1578], 78.52% of total effect). Study 2 confirmed the longitudinal chain.
conclusionsThis study reveals a cognition-emotion-resource-behavior mechanism underlying the association between balanced time perspective and short-video addiction. It enriches the existing research on short-video addiction prevention from the perspective of time psychology and provides theoretical implications for developing targeted intervention strategies to reduce adolescent short-video addiction.
