Psychometric validation of the positive youth development scale-short form in Peruvian university students.
Article in Frontiers in 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
Introduction: Evidence on the psychometric performance of the Positive Youth Development Scale-Short Form (PYD-SF) in Spanish-speaking university populations remains limited. This study examined evidence based on internal structure, measurement invariance across sex, internal consistency, the empirical distinctiveness of the five dimensions, and relations with purpose in life for PYD-SF scores in Peruvian university students. Methods: A cross-sectional instrumental study was conducted with 1,015 Peruvian university students aged 18 to 30 years. Confirmatory factor analysis was performed using the diagonally weighted least squares (DWLS) estimator for ordinal data. Measurement invariance across sex, internal consistency, the empirical distinctiveness of the five dimensions, and relations with purpose in life were also assessed. Results: The findings supported a correlated five-factor structure consistent with the theoretical 5Cs model. Strict measurement invariance across sex was established. Internal consistency coefficients were generally acceptable, although the categorical omega coefficient for Caring was marginal. Heterotrait-monotrait ratios remained below 0.85, and all five dimensions showed positive and statistically significant correlations with purpose in life. Conclusion: The findings provide evidence based on internal structure, internal consistency, measurement invariance across sex, the empirical distinctiveness of the five dimensions, and relations with purpose in life for PYD-SF scores in Peruvian university students. These results support their use for group-level research in comparable university populations.
