Self-esteem and psychological well-being as predictors of life satisfaction among university students in southern Peru: a cross-sectional predictive study.
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
backgroundSelf-esteem and psychological well-being are fundamental pillars of individuals' integral development, especially during the university stage, when students face multiple personal challenges and intense academic demands.
objectiveThis study aimed to determine whether self-esteem and psychological well-being predicted life satisfaction among university students in southern Peru.
methodThe sample of 506 university students, aged 18 to 30 years (M = 22.1; SD = 2.84), participated in this cross-sectional predictive study. The data were collected from three universities in southern Peru via non-probabilistic convenience sampling. The instruments were the Rosenberg Self-Esteem Scale, the BIEPS-A Psychological Well-Being Scale for Adults, and the Satisfaction with Life Scale. Hierarchical regression analysis was performed.
resultsHierarchical regression showed that psychological well-being dimensions (ΔR²=0.426) and self-esteem (ΔR²=0.157) significantly predicted life satisfaction, explaining 59.6% of the variance, while sociodemographic variables showed no significant contribution (R²=0.013,p = 0.240). Self-esteem was the strongest predictor in the final model (unstandardized B = 0.363, SE = 0.026, β = 0.572,p < 0.001), followed by the psychological well-being dimension of social bonds (B = 0.424,SE = 0.087,β = 0.185,p < 0.001).
conclusionThe self-esteem and psychological well-being dimensions are significant predictors of life satisfaction among university students in southern Peru, with self-esteem also operating as a mediating mechanism linking psychological well-being to life satisfaction.
