The effect of Leventhal’s Self-Regulatory Intervention on the hypertensive patients’ Illness Perception and Lifestyle: A randomized controlled trial

Abstract

Abstract BackgroundThe perception of illness may lead to the improvement of the hypertensive patients’ lifestyle, but no study was found in this regard. Therefore, this study was conducted to determine the effect of intervention based on Leventhal’s self-regulatory model on illness perception and lifestyle of patients with hypertension.MethodsIn the present randomized controlled trial study, ninety eligible patients with primary hypertension were randomly assigned to one of the two groups of intervention and control. Patients in the intervention group received five sessions of Leventhal’s self-regulatory intervention, and the control group received routine care. The outcomes were illness perception and lifestyle of the patients with hypertention. The Revised Illness Perception Questionnaire and the Lifestyle Questionnaire were administered to assess illness perception and lifestyle prior to the treatment to establish a baseline and subsequently 12 weeks after the intervention. The collected data was analyzed, using statistical IMB SPSS software, version 21. ResultsLeventhal’s self-regulatory intervention improved subscales of illness perception (p<0.05) except for emotional representations and consequences. The global mean scores of the hypertensive patients ̓ lifestyle in the intervention group significantly increased from 102.8±2.3 at the baseline to 112.1±3 post intervention.Conclusions: Interventions based on Leventhal’s self-regulatory model could improve illness perception and lifestyle of patients with hypertension.
