Abstract: (15 Views)

Background and Objective: Coronary artery disease accompanied by various physical and psychological consequences for patients. One of the key factors in managing this disease is patients’ proper understanding of the illness and their adherence to treatment. In this regard, utilizing effective educational models such as Leventhal’s Model can be a promising approach to improving treatment adherence in these patients. Therefore, the present study was conducted to investigate the effect of education based on this model on illness perception and treatment adherence among Individuals with coronary artery disease hospitalized.

Materials and Methods: In this quasi-experimental study, 80 patients with coronary artery disease were selected using a convenience sampling method based on inclusion criteria and were randomly assigned to intervention and control groups. Data collection tools included a demographic information form, the Brief Illness Perception Questionnaire (Brief IPQ), and the Seyed Fatemi Treatment Adherence Questionnaire. The intervention group received four educational sessions based on Leventhal’s Self-Regulation Model. Data were analyzed using chi-square, independent t-test, paired t-test, and Fisher’s exact test in SPSS software version 27.

Results: The mean changes in illness perception scores in the intervention and control groups were 6.57 ± 1.272 and 0.07 ± 0.034, respectively, and the mean changes in treatment adherence scores were 5.82 ± 0.074 and 0.05 ± 0.267 for the intervention and control groups, respectively. These changes were statistically significant in the intervention group (P < 0.001), and education based on Leventhal’s model led to improvements in all dimensions of These two variables in the intervention group (P < 0.05).

Conclusion: Individual education based on Leventhal’s model is an effective method for improving illness perception and treatment adherence in patients with coronary artery disease, and it is recommended that this approach be used to design targeted individual education programs for these patients.
