Hypertension is one of the more common comorbidities among patients infected with the Sars-CoV-2 virus, which causes COVID-19, but many hypertensive patients do not comply with taking medication. This study analyzed the relationship of self-motivation and health locus of control with self-management (medication adherence) among hypertensive patients during the COVID-19 pandemic at Private Hospital Surabaya, Indonesia. The research adopted a correlative analytic design with a cross-sectional approach, and the study’s population comprised 74 hypertensive patients recruited by simple random sampling who were treated at Private Hospital Surabaya, Indonesia The instruments used included the Treatment Self-Regulation Questionnaire to measure self-motivation, the Multidimensional Health Locus of Control Scale to measure locus of control, and the Morisky Medication Adherence Scale–8 to measure self-management (medication adherence). Spearman’s rank correlation coefficient was employed for data analysis to measure the relationships between self-motivation, locus of control, and with self-management (adherence to taking medication). The results reveal a relationship between self-motivation and adherence to medication at a level of p = 0.000 and a relationship between health locus of control and adherence to taking medication at a level of p = 0.000 among hypertensive patients during the COVID-19 pandemic at Private Hospital Surabaya, Indonesia. The findings suggest the value of efforts to provide motivation to patients and support their being more responsible in controlling their health conditions by adherence to medication.
