Psychometric properties of Persian version of diabetes health literacy scale (DHLS) in patients with type 2 diabetes

Abstract

Background The purpose of this study was to investigate the psychometric properties of the Persian version of Diabetes Health Literacy Scale in type 2 diabetic patients. Method This cross-sectional study was conducted in 2021 in 1040 patients with type 2 diabetes in eastern Iran. Participants was selected by proportional stratified sampling method. The validity of DHLS was investigated through qualitative face validity, qualitative content validity, and structural validity (exploratory factor analysis and confirmatory factor analysis). The reliability of DHLS was checked by Cronbach's alpha coefficient, McDonald omega coefficient, and test–retest. Results In exploratory factor analysis, 3 factors with eigenvalues greater than 1 were extracted, explaining 68.57% of the variance. These factors entered the confirmatory factor analysis, none of the questions were removed, and all questions had factor loading above 0.4. Cronbach's alpha coefficient and McDonald omega coefficient of DHLS were 0.919 and 0.922. Also, the Intraclass correlation coefficient of DHLS was 0.957. Finally, the DHLS was approved with 14 questions and the three subscales of Informational Health Literacy (6 items), Numerate Health Literacy (5 items), and Communicative Health Literacy (3 items). Conclusions DHLS with 14 questions and the three subscales is a valid and reliable tool for examining diabetes health literacy in people with type 2 diabetes.

The evaluation of the role of diabetes health literacy and health locus of control on quality of life among type 2 diabetes using the Path analysis

“…4) Diabetes health literacy scale (DHL): The questionnaire was designed by Lee and consisted of 14 questions and three subscales of Numerate Health Literacy (5 items), Informational Health Literacy (6 items), and Communicative Health Literacy (3 items) 33 . The validity and reliability of this tool in Iranian population has been verified by Moshki 34 and Cronbach's alpha for all questions and subscales of Numerate Health Literacy, Informational Health Literacy, and Communicative Health Literacy were 0.919, 0.879, 0.865, and 0.784, respectively 34 . Path analysis.…”
