Health literacy and trust in health information sources in Ireland: anonymised survey data

This dataset contains the anonymised respondent-level data from an online descriptive cross-sectional survey of health literacy and trust in health information sources among adults living in Ireland. Respondents (n = 448) were recruited through Prolific and completed the survey on QuestionPro between 18 and 24 March 2025.

The survey included the Health Literacy Questionnaire (HLQ) Parts 1 and 2, demographic and health-service questions, and questions on how often respondents use different sources of health information.

The deposit contains:

• iHF_health_literacy_survey_anonymised_v2.csv and .xlsx: the anonymised data (448 rows × 71 columns), identical in content
• iHF_codebook_v2.xlsx: variable list, value labels and recoding details
• qualitative_coding_framework_v1.1.pdf: the framework used to code the free-text responses (the responses themselves are not deposited)
• README_iHF_health_literacy_survey_v2.pdf: full documentation

To protect anonymity, demographic variables have been banded and some values suppressed, and all free-text responses have been removed. The survey weights used in the associated paper are not included. Please read the README before analysing the data.

HLQ item wording is not included, because the HLQ is the intellectual property of Swinburne University of Technology and was used under licence.
