Key result
Higher patient self-efficacy is paradoxically linked to lower medication adherence in hypertension, where ~88% report nonadherence.
Why the study?
Hypertension is a major public health concern in Saudi Arabia, where poor medication adherence and inadequate self-care contribute to uncontrolled blood pressure and increased morbidity.
Cross-Sectional (n=408)
Effect estimate: r = -0.251
A large majority (88.2%) of hypertensive patients in Saudi Arabia report low medication adherence, which correlates negatively with self-efficacy, highlighting the need for behavioral interventions.
May guide adherence interventions targeting self-efficacy; leaves open causal effects and efficacy in prospective trials.
Background Hypertension is a major public health concern in Saudi Arabia, with poor medication adherence and inadequate self-care contributing to uncontrolled blood pressure and increased morbidity. Aim This study aimed to assess levels of medication adherence and self-care behaviors among hypertensive patients in Saudi Arabia and to explore how patient perceptions—behavior, motivation, and self-efficacy—affect adherence. Methods A cross-sectional study was conducted among 408 hypertensive patients using the Morisky Medication Adherence Scale (MMAS-8) and the Hypertension Self-Care Profile. Data were analyzed using SPSS v29. Results Low medication adherence was reported by 88.2% of participants. Females showed higher self-care perceptions, while males had higher adherence scores ( P = 0.0088). Younger adults (18–29 years) had the lowest adherence and self-care scores. Significant negative correlations were found between MMAS scores and self-efficacy ( r = −0.251). Conclusion Patient perceptions, particularly self-efficacy, are strongly associated with adherence. Culturally tailored behavioral interventions are needed to improve hypertension management outcomes.

A 2025 study conducted a cross-sectional in Hypertension (n=408). Patient perceptions (behavior, motivation, and self-efficacy) was evaluated on Medication adherence and self-care behaviors (r = -0.251). Patient self-efficacy was significantly negatively correlated with medication adherence (r = -0.251) among hypertensive patients, 88.2% of whom reported low adherence.
