Cross-cultural adaptation and reliability assessment of the Ecuadorian youth risk behavior survey in Ecuadorian adolescents.
Article in Frontiers in pediatrics, 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
Background: Reliable and culturally adapted instruments are essential for monitoring health-risk behaviors among adolescents and supporting evidence-based public health interventions. The Youth Risk Behavior Survey (YRBS) is widely used internationally; however, no culturally adapted version had previously been evaluated for use among Ecuadorian adolescents. Objective: To assess the internal consistency and test-retest reliability of the Ecuadorian adaptation of the Youth Risk Behavior Survey (EYRBS). A cross-sectional study with a longitudinal test-retest component was conducted among 356 adolescents aged 12-17 years from public schools in Ecuador. The Spanish version EYRBS was administered online. To evaluate temporal stability, 67 participants completed the questionnaire a second time 15 days after the initial administration. Internal consistency was assessed using Cronbach's alpha coefficient and McDonald omega. Test-retest reliability was evaluated using the intraclass correlation coefficient (ICC) based on a two-way mixed-effects model with absolute agreement. Results: The final version of the EYRBS consisted of 51 items organized into two domains: Social Aspects and Health Aspects. The overall Cronbach's alpha coefficient was 0.686, while the Social Aspects and Health Aspects domains achieved alpha values of 0.616 and 0.644, respectively. Internal consistency, assessed via McDonald's omega ( Conclusions: The EYRBS demonstrated acceptable internal consistency and excellent temporal stability, providing initial evidence of reliability. Structural validity and advanced psychometric evaluations are intentionally deferred to a subsequent, separate investigation.
