Aims: Medication adherence is one of the most important concepts in the field of physical diseases, including hypertension. Many patients do not adhere to the treatment and ignore the doctor's instructions, which can cause many economic, physical, and cultural problems for the individual, family, and society. This study aimed to investigate the factors related to mediation adherence using social cognitive theory in hypertensive patients. Instrument & Methods: This descriptive-analytical study was carried out on ۱۱۲ patients (male and female) with hypertension in Yasuj, Iran in ۲۰۲۰. Data collection tools included the demographic information questionnaire, the Maurice therapy adherence questionnaire, and the bandura social theoretical constructs questionnaire (including self-efficacy, social support, and self-regulatory constructs). the collected data were analyzed using SPSS ۲۲ software. Findings: The rate of treatment adherence was ۴۶.۴% among patients (۵۵.۶% for men and ۴۰.۳% for women). There was a statistically significant relationship between age, education, and adherence to treatment (p<۰.۰۰۰۱). The self-efficacy self-regulatory constructs predicted ۲۲% of the variance in treatment adherence. Conclusion: The results of this study showed that medication adherence in hypertensive patients referred to medical centers in Yasuj is at a weak level. Due to the correlation between the constructs of social cognitive theory and mediation adherence, the constructs of this theory can be used in adherence to treatment in patients with hypertension.
