The Medication Understanding and Use Self-Efficacy Scale is a reliable tool with a two-factor structure for measuring medication self-efficacy in patients with hypertension.
Supports self-efficacy scale validation for Iranian hypertension patients; leaves open predictive utility for adherence or outcomes.
Introduction This study was designed to determine self-efficacy and its related factors in patients with hypertension. Materials and methods This study is descriptive-sectional from the correlation. A total of 250 patients from a blood pressure clinic of Semnan city (in Iran) completed Medication Understanding and Use Self-Efficacy Scale were randomly selected in 2017. Data were analyzed using variance, Pearson’s Correlation, and χ2 using the LISREL 8.8 software. Results The items 1, 6, 7, and 8 have high correlation (at least higher than 0.60), indicating the possibility of aggregation of these four variables in the first factor (taking medication), and the four items 2, 3, 4, and 5 are highly correlated with each other, which are the second factor (learning about medication). In addition, Cronbach’s α of reliability (taking medication) for the first factor was 0.67 and 0.63 for the second factor (learning about medication) and 0.69 for the whole scale. Conclusion The effectiveness of blood pressure self-efficacy is an appropriate tool for measure-taking responsibility for the time and taking medications by patients, and researchers can use it as a valid tool in therapeutic, psychological, and health research.

Ghadiri et al. (2018) conducted a cross-sectional in Hypertension (n=250). Medication Understanding and Use Self-Efficacy (MUSE) Scale was evaluated on Construct validity and internal consistency (Cronbach's alpha) of the MUSE scale. The Medication Understanding and Use Self-Efficacy Scale demonstrated a valid two-factor structure and acceptable internal consistency with an overall Cronbach's alpha of 0.69 in patients with hypertension.
