Psychometric Validation of the Korean Preparedness to Help Scale for Assessing Adolescents' Readiness to Support Peers at Risk of Suicide.

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
Purpose: Adolescents are often the first to recognize emotional distress and suicidal warning signs among their peers, making their readiness to provide appropriate support an essential component of school-based suicide prevention. However, no validated Korean version of the Preparedness to Help Scale (PHS) is currently available for adolescents. This study aimed to translate and culturally adapt the PHS into Korean and evaluate its validity and reliability among Korean adolescents. Patients and Methods: A cross-sectional psychometric validation study was conducted with 434 middle and high school students in South Korea. Construct validity was examined using confirmatory factor analysis (CFA). Convergent validity was evaluated using standardized factor loadings, average variance extracted (AVE), and composite reliability (CR). Criterion-related validity was examined through concurrent validity and known-groups validity. Internal consistency was evaluated using Cronbach's α and McDonald's ω. Results: CFA yielded fit indices consistent with the hypothesized unidimensional structure, although these indices should be interpreted cautiously given the model's two degrees of freedom (χ Conclusion: The Korean PHS demonstrated promising initial psychometric properties for assessing adolescents' preparedness to support peers at risk of suicide. It may provide a brief and feasible measure for school-based suicide prevention and peer gatekeeper program evaluation, although further validation in diverse samples and against behavioral outcomes is warranted.
