  • Hypertension (HTN) is a serious health issue across the globe. Oman, an Arabic Muslim country located in the Middle East, has high prevalence of HTN and uncontrolled blood pressure (BP). Appropriate management of HTN and control of BP require adherence to antihypertensive medication to prevent HTN-related serious complications. Worldwide, proper adherence remains a challenge. Several factors contribute to medication adherence among patients with HTN. Patients’ beliefs about HTN and medication are among the significant predictors of medication adherence. In Oman, studies that examined patients’ health beliefs of patients with HTN as determinants of medication adherence are not available. Hence, this dissertation aimed to examine the relationship between beliefs about the necessity of and concerns about medication, beliefs about HTN, and self-efficacy and medication adherence among Omanis with HTN. The health beliefs model was used to guide this dissertation. Three manuscripts were produced to achieve the overall purpose of this dissertation. The first manuscript is a systematic review of available quantitative evidences on the relationship between patients’ different health beliefs and medication adherence among patients with HTN. The second and third manuscripts constituted a pilot study and a main study, respectively, which reported findings on the relationship between patients’ beliefs (HTN severity, medication necessity, medication concerns, and self-efficacy) and medication adherence among Omanis with HTN. The main finding of the three manuscripts were that patients with stronger beliefs about the necessity of antihypertensive medications, fewer concerns regarding medication side effects, long-term and dependency effects, and higher self-efficacy regarding medication adherence significantly associated with high adherence. Findings of this dissertation denote that patients’ beliefs are important determinants of medication adherence and should be considered by clinicians and researchers to optimize adherence to antihypertensive medications.
