The Effect of an Educational Intervention According to Hygienic Belief Model in Improving Care and Controlling among Patients with Hypertension

Patients play a major role in controlling and treatment of hypertension. Therefore، to be aware of different aspects of this disease is very important for these patients. This study was conducted to determine the effectiveness of the Hygienic Belief Model (HBM) on the health education of patients with hypertension. This study was an educational trial. Two hundred hypertensive patients attending health centers in Bam city، were selected to participate in this study (100 in intervention group and 100 in control group). The educational intervention was conducted during three 60-minute sessions. Data were collected by a validity and reliability questionnaire containing (64 questions) before educational intervention and three months after it. Data was analysed by chi-square، Fisher''s exact، paired t-test and independent t-test. After intervention، knowledge scores increased in the intervention group compared to the control group (p<0. 001). Perceived susceptibility، perceived severity، perceived benefits and barriers، cues in order to action، and self-efficacy significantly increased in the intervention group compared to the control one (p<0. 001). But، there was no addition or significant difference in the control group. Also systolic and diastolic blood pressures significantly decreased in the intervention group compared to the control one (p<0. 05). HBM was effective in educating hypertensive patients. Therefore، it is proposed to apply the HBM in training hypertensive patients as well as traditional training methods.
