A predictive and moderation model of depression in adolescents, and the creation of the Javier-Aliaga's single-item scales of happiness and self-efficacy (version 1.0).
Article in BMC psychology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundThe high prevalence of depression among adolescents highlights the need for research aimed at identifying variables with predictive capacity for this condition. In parallel, the scarcity of single-item scales assessing happiness and self-efficacy underscores the importance of developing validated instruments tailored to the Peruvian context. This study aims to examine the predictive roles of perfectionism, self-efficacy, and happiness on depression, as well as the moderating role of sex among Peruvian adolescents. Additionally, it proposes the development of two new instruments: the Javier-Aliaga's Single-Item Scale of Happiness and the Single-Item Scale of Self-Efficacy.
methodsA cross-sectional predictive study was conducted in 380 adolescents from a public school in Lima, Peru, of whom 50.3% were male and M
resultsThe multiple regression analysis showed that Model 2 was the most appropriate (F = 128, p < 0.001, BIC = 2878). The variables perfectionism (β = 0.283, CI [0.215, 0.351], p < 0.001), self-efficacy (β = -0.236, CI [-0.312, -0.161], p < 0.001), happiness (β = -0.386, CI [-0.463, -0.309], p < 0.001), and sex (β = 0.239, CI [0.170, 0.307], p < 0.001) explained 57.3% of the variability in depression (adjusted R
conclusionThe findings highlight the significant influence of perfectionism, self-efficacy, and happiness on depression among Peruvian adolescents, with happiness emerging as the most impactful variable. Moreover, the moderating role of sex suggests that interventions targeting these factors should be designed differently for males and females. Additionally, the development and validation of the JASIHS-v1.0 and the JASISS-v1.0 represent a valuable contribution by providing brief, culturally relevant, and psychometrically sound instruments.
