The Effect of the Intervention Based on Protection Theory on the Drug Compliance of the Patients with Ischemic Heart Disease

The patients with ischemic heart disease gradually stop following their treatment and self-care behaviors due to vulnerable physical conditions and high involvement in the treatment process. Therefore the present study was conducted to investigate the effect of the intervention based on protection theory on the drug complianceof the patients with ischemic heart disease.

The present study was quasi-experimental with pretest, posttest and control group design. The statistical population of the present study included the patients with ischemic heart disease at Payamabar-e-A’zam hospital in Bandar Abbas  who came there more than once in the period of March 2019 to May 2020. 16 patients with ischemic heart disease were selected through purposive sampling via paired method and randomly accommodated into experimental and control groups (each group of 8 patients). The experimental group received six ninety-minute sessions of protection motivation theory intervention during one-and-a-half months. The applied questionnaire included drug compliancequestionnaire (Morisky et.al, 2008). The data were analyzed through ANCOVA method via SPSS23 software.

The results of ANCOVA method showed that the intervention based on protection motivation theory has been effective on the drug compliancein the patients with ischemic heart disease (p<0.001) in a way that this type of intervention led to the increase of drug compliance (0.46)in these patients.

According to the findings of the present study it can be concluded that the intervention based on protection motivation theory can be used as an efficient intervention to increase drug compliance of the patients with ischemic heart disease with the emphasis on teaching correct nutrition, self-care skills, increasing awareness, and relaxation exercises.
