Insights
Motivational interviewing (MI) can improve illness perception in patients with coronary heart disease (CHD). A short MI intervention positively affected emotional reactions to the disease in CHD patients post-PTCA.
Area of Science:
- Cardiology
- Psychology
- Health Behavior
Background:
- Coronary heart disease (CHD) is a leading cause of death in individuals over 60.
- Lifestyle factors significantly influence CHD risk.
- Effective cardiac rehabilitation requires patients to understand their condition, which is often lacking.
Purpose of the Study:
- To evaluate the impact of motivational interviewing (MI) on illness perception in patients with stable CHD.
- To assess if a brief MI intervention enhances understanding of CHD and its risk factors.
Main Methods:
- A randomized-controlled trial involving 312 patients with stable CHD after percutaneous transluminal coronary angioplasty (PTCA).
- The intervention group received a short MI session; the control group received usual care.
- Illness perception was measured using the Illness Perception Questionnaire-Revised before and six months after the intervention.
Main Results:
- A significant improvement was observed in the emotional reactions domain of illness perception after the MI intervention.
- The study included 312 patients (148 intervention, 164 control) with a mean age of 66.2 years.
Conclusions:
- A single, short motivational interviewing intervention may be effective in improving illness perception in stable CHD patients.
- Further research is needed to determine if more intensive MI interventions yield greater benefits.
Abstract:
Background: Coronary heart disease (CHD) constitutes one of the most frequent causes of death for individuals > 60 years. Lifestyle dependent risk factors are key. Hence, cardiac rehabilitation is essential for optimal CHD treatment. However, individuals rarely comprehend their illness. Motivational interviewing promotes illness perception. Aim/Methods: A randomised-controlled study was conducted to determine the effect of motivational interviewing on illness perception. Patients with stable coronary heart disease were consecutively recruited after elective percutaneous transluminal coronary angioplasty (PTCA). The intervention group received a short motivational interview (MI) about the disease and related risk factors as an intervention. The control group had usual treatment. Illness perception was assessed (Illness Perception Questionnaire-Revised) prior to the intervention and six months afterwards. Results: A total of 312 patients (intervention group: n = 148, control group: n = 164) were recruited into the study (mean age: 66.2 years). After the intervention, a significant change was observed in the domain of emotional reactions regarding the disease. Conclusion: To improve illness perception in patients with stable CHD, one short intervention with MI may have an effect. Whether intensifying the MI-intervention is more effective, requires further research.
