Effect of Modular Training on Self‐Management, Disease, and Treatment Adaptation in Individuals With Hypertension: A Randomized Controlled Trial

Hypertension requires sustained self-management, behavioral adaptation, and effective patient education. Individuals often experience insufficient knowledge, low motivation, and difficulty maintaining treatment behaviors. This randomized controlled trial evaluated the effect of nurse-led modular education on self-efficacy, medication adherence, and disease adaptation in hypertensive individuals. A pretest/posttest randomized controlled trial was conducted with 46 hypertensive adults (intervention = 23, control = 23) in an internal medicine outpatient clinic. Data were collected using the Hypertension Self-Efficacy Scale (HSES), Modified Morisky Scale (MMS), and Adaptation to Chronic Illness Scale (ACIS). The intervention group received one face-to-face session and four modular educational sessions via telephone over 12 weeks. The control group received routine care and completed the same measurements. Intervention participants demonstrated significant improvements in self-efficacy (p = 0.001), medication knowledge (p = 0.001), motivation (p = 0.011), and total disease adaptation (p = 0.001). No significant improvement was observed in psychological adaptation. The control group showed a significant decline in self-efficacy and total adaptation scores. Nurse-led modular education significantly improved key hypertension self-management outcomes, including self-efficacy, medication knowledge, and physical and social adaptation to chronic illness. However, blood pressure control rates were not assessed as a primary outcome. Trial Registration: ClinicalTrials.gov: NCT06816732.
