Abstract:
Objective To develop a self-assessment scale for medication literacy in patients with coronary heart disease comorbidity diabetes and to test its reliability and validity.Methods According to medication literacy theory model,the initial scale was formed through literature review,the qualitative interview and expert inquiry.Cognitive interview was used to optimize the expression of item text.421 patients with coronary heart disease comorbidity diabetes in a tertiary hospital in Zhejiang province from November 2022 to April 2023 were selected to investigate the reliability and validity of the scale by convenience sampling.Results The self-assessment scale of drug literacy for coronary heart disease comorbidity diabetes mellitus included 23 items in 5 dimensions including acquisition,understanding,communication,evaluation and calculation.The total Cronbach's α coefficient of the scale was 0.911;the retest reliability was 0.948;the average content validity index was 0.997;the correlation coefficients between each dimension and total score of the scale and the calibration scale ranged from 0.485 to 0.926.The exploratory factor analysis was employed to extract 5 common factors,and the cumulative variance contribution rate was 73.753％.Confirmatory factor analysis showed that the scale factor structure was stable.Conclusion The scale has good reliability and validity,and it can be used as an effective tool to evaluate the self-rated medication literacy level of patients with coronary heart disease comorbidity diabetes.
