Development and effectiveness of a digital health literacy improvement program (DHL-Up) for multicultural children and adolescents in South Korea: a quasi-experimental study.
Article in Child health nursing research, 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
purposeDigital health literacy is essential for health management among children and adolescents, with multicultural youth being particularly vulnerable to challenges in accessing, appraising, and using digital health information. This study aimed to develop a digital health literacy improvement program (DHL-Up) tailored to multicultural children and adolescents and evaluate its effectiveness.
methodsGuided by the Transactional Model of eHealth Literacy and the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model, a five-session program was developed to strengthen functional, communicative, critical, and translational digital health literacy. A non-equivalent control group pretest-posttest design was used. The participants included 31 multicultural children and adolescents aged 10-15 years (experimental group: 14; control group: 17). The experimental group participated in a 5-week online program (60 minutes per session) delivered to small groups via Zoom. Data were collected before and after the intervention and analyzed using descriptive statistics, independent t-tests, Mann-Whitney U tests, chi-square tests, and Fisher's exact tests.
resultsThe experimental group showed significantly greater improvements in digital health literacy (t=2.73, p=.011) and the usefulness of Internet health information (t=3.11, p=.004) than the control group. No significant difference was found for information overload (t=-0.17, p=.854).
conclusionThis study developed and validated a tailored digital health literacy intervention for multicultural children and adolescents, demonstrating its applicability in schools, public health centers, and community settings. These findings provide foundational evidence to support the institutionalization of digital health literacy education and highlight its potential to mitigate digital health information disparities among vulnerable populations.
