The Effect of Applying the Information- Motivation-Behavioral Skills Model on Treatment Adherence in Patients with Cardiovascular Disease: A Quasi-Experimental Study
Abstract
Background: Non-adherence complicates the management of patients with cardiovascular disease.This study aimed to determine the effect of applying the information-motivation-behavioral skills(IMB) model on the treatment adherence among these patients.Methods: This quasi-experimental study was conducted on 112 patients with cardiovascular diseasein Nemazee and Al-zahra hospitals in Shiraz, Iran, from October 2019 to July 2020. Eligible patientswere selected and divided into intervention and control groups. The intervention was based on anintegration of IMB model constructs and included 10 motivational-educational sessions for threemonths, followed by telephone consultations for six months. Data were collected before, and three andsix months after the end of the motivational-educational sessions using adherence questionnaire inpatients with chronic diseases, and adherence in chronic disease scale for medication adherence. Datawere analyzed using SPSS 22, and descriptive statistics, chi-square, independent t-test, and repeatedmeasure ANOVA were performed. p Results: The intervention and control groups were homogenous based on demographic characteristics.Repeated measure ANOVA findings revealed an increasing trend in the mean scores of the interventiongroup in treatment adherence from 51.10±3.20 at baseline to 66.40±5.50 three months and 73.80±6.80six months after the end of the intervention (p <0.001). Furthermore, based on repeated measureANOVA findings, the mean score of the intervention group in medication adherence significantlyincreased from 20.10+3 at baseline to 24.10+2.40 three months and 24.50+3.20 six months after theend of the intervention (p <0.001).Conclusion: Applying the IMB model promoted adherence to treatment and medication among patientswith cardiovascular disease. Therefore, such interventions are recommended for these patients.
