This cross-sectional study describes the conceptualization, development, and psychometric properties of the first Chinese Medication Literacy Measurement (ChMLM) to assess the level of health literacy on medication use. The 17-item ChMLM (ChMLM-17) and its short form, 13-item ChMLM (ChMLM-13), consist of four sections (vocabulary, over-the-counter labels, prescription labels, and advertisements) to cover six domains of medication-related health literacy. Multistage stratified quota sampling was attempted to recruit a representative sample in Taiwan. Receiver operating characteristic curves were used to identify the cut-off point for differentiating high and low medication literacy. Psychometric analyses were performed (n = 1410) to assess the reliability and validity separately on all samples and sociodemographic subgroups. The 17- and 13-item versions both had high construct validity among all patients and patients with low medication literacy. The developed ChMLM-17 and ChMLM-13 is expected to help healthcare providers and researchers to accurately measure medication-related health literacy and improve medication use in the real-world practice.enhealth literacy; health professionals; medication literacy; psychometric propertiesHealth literacy; Health professionals; Medication literacy; Psychometric properties[SDGs]SDG3non prescription drug; conceptual framework; health care; literacy; measurement method; public health; adult; aged; Article; assessment of humans; Chinese Medication Literacy Measurement 13 item; Chinese Medication Literacy Measurement 17 item; clinical practice; conceptual framework; construct validity; controlled study; cross-sectional study; demography; drug marketing; drug use; female; health literacy; health survey; human; major clinical study; male; medical terminology; pilot study; prescription; psychometry; reliability; Taiwan; Asian continental ancestry group; attitude to health; concept formation; patient education; psychometry; questionnaire; reproducibility; Taiwan; Asian Continental Ancestry Group; Concept Formation; Cross-Sectional Studies; Health Knowledge, Attitudes, Practice; Health Literacy; Humans; Patient Education as Topic; Patient Medication Knowledge; Psychometrics; Reproducibility of Results; Surveys and Questionnaires; Taiwanjournal article10.3390/ijerph17196951329775202-s2.0-85091363948https://api.elsevier.com/content/abstract/scopus_id/85091363948
