The Impact of Intervention Based on Protection Motivation Theory on Treatment Adherence in Patients with Ischemic Heart Disease

Abstract

Background: Patients with ischemic heart disease (IHD) gradually reduce their follow-up treatment due to the vulnerable physical condition and high involvement with the disease-related treatment process. The purpose of this research was to investigate the effect of intervention based on the protection motivation theory (PMT) on treatment adherence in patients with IHD. Methods: This quasi-experimental research used a pretest-posttest design with a control group. The statistical population included all patients with IHD referred to the Payambar Azam hospital in Bandar Abbas, Iran for more than once between March 2019 and May 2020. A total of 16 patients were selected through the matched targeted sampling and randomly assigned into two equal groups of experimental and control (n = 8 each). The test group received an intervention based on the PMT in six 90-minute sessions within 45 days. We used the Modanloo Treatment Adherence Questionnaire (TAQ), and the data were analyzed using the analysis of covariance (ANCOVA) in the SPSS23 statistical software. Results: The results of ANCOVA showed that the intervention based on the PMT significantly increased the treatment adherence and its subscales in patients with IHD (P<0.001). Conclusion: Intervention based on the PMT can be used as an effective intervention to increase treatment adherence in patients with IHD, depending on proper nutrition training, self-care skills, awareness-raising, and relaxation exercises.

“…This finding is compatible with the findings of studies by Mirkarimi et al, Sanaie et al, and Posht-Chaman et al (4,11,12). A study by Zakipour et al showed that teaching proper nutrition, self-care skills, and relaxation exercises based on the protection motivation theory effectively improved self-care in patients with ischemic heart disease (18). Habibzadeh et al also reported that implementing the Health Belief Model could significantly increase the mean scores of all components of treatment adherence in patients with CAD.…”

Development and validation of a questionnaire based on the protection motivation theory to predict cigarette smoking preventive behavior in the Iranian university students

“…[ 13 ] Previous studies have shown that both factors that make up the theory with high power are able to predict a person's intentions and behavior; especially, the coping appraisal factor and the self-efficacy component provide a strong prediction of a person's behavior. [ 1 15 ] PMT has been used in various studies to prevent a behavior, for example, to prevent risky behaviors such as acquired immunodeficiency syndrome (AIDS),[ 16 ] cardiovascular disease,[ 17 18 19 ] Ebola infection,[ 20 ] corona virus,[ 21 ] coronavirus vaccination.
