Health literacy scale for English-speaking children: translation and validation of the HLS-Child-Q15-EN.
Article in BMJ open, 2025. 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
objectiveTo translate and validate the HLS-Child-Q15, a relatively short questionnaire for assessing health literacy in children originally validated in German, into English to make it accessible to a large population of English-speaking children.
designWe translated the HLS-Child-Q15 into English following established methods, including forward and backward translation, using multiple translators. We incorporated clinician and consumer input into the translation process. We conducted a qualitative pre-test to assess comprehension and a validation to assess psychometric properties and test-retest reliability.
settingPerth Children's Hospital, Perth, Western Australia PATIENTS: We recruited English-speaking children aged 8 to 15 years.
main outcome measuresQualitative analysis of pre-test interviews, Cronbach's α coefficient for internal consistency and intraclass correlation coefficient for test-retest reliability.
resultsThe translation process yielded an acceptable translation. A qualitative pre-test conducted with 10 children demonstrated good comprehension of questionnaire items and resulted in small changes to increase item clarity. Validation with 207 participants demonstrated that questionnaire output score increased with age, school year, self-efficacy score, parental educational level and home literacy environment score. Internal consistency was assessed, with a Cronbach's α coefficient of 0.854 (95% CI 0.812 to 0.887). Test-retest reliability was moderate, with an intraclass correlation coefficient of 0.612 (95% CI 0.402 to 0.761).
conclusionsThe translated HLS-Child-Q15 was well understood by children. Validation of the translated questionnaire demonstrated adequate psychometric properties, consistent with the original German questionnaire. The translated HLS-Child-Q15 is suitable for use with English-speaking children.
