RESUMO
Objective To evaluate the methodological quality and measurement characteristics of health literacy assessment tools for diabetic patients and to provide references for medical staff to select the best assessment tools.Methods The PubMed,Embase,CINAHL,Web of Science,CNKI,VIP database,Wanfang Data,and Chinese Biomedical Database were searched from inception to December 31,2022.Data were screened and extracted independently by 2 researchers.The consensus-based standards for the selection of health measurement instruments(COSMIN)system evaluation guidelines were spontaneously used to evaluate the included assessment tools.Finally,recommendations were made.Results A total of 15 studies were included,involving 12 health literacy assessment tools for diabetic patients.Among them,KHLS-DM and DNT-15 have satisfactory content validity and internal consistency and are recommended as Grade A.HLSQ-3 has high-quality evidence to suggest that its internal consistency is"inadequate"and recommended as Grade C,while the other 9 scales are recommended as Grade B for content validity or internal consistency of uncertain/inadequate evidence at or above the intermediate level.Conclusion KHLS-DM can evaluate written literacy,numeracy,and critical literacy of patients,and each measurement characteristic has been comprehensively evaluated with high reliability and validity,so it is recommended to be applied first.DNT-15 focuses on evaluating the numeracy of patients,which can be used in combination with other scales to evaluate health literacy of patients more comprehensively.
