This study is a prospective, randomized controlled clinical trial designed to evaluate the effects of a structured mind-body intervention on psychological outcomes in patients with stable coronary artery disease.
Eligible participants will be recruited from Ufuk University Department of Cardiology and randomly assigned to either an intervention group or a control group using a simple randomization method. The intervention group will receive eight individualized sessions of progressive muscle relaxation and guided imagery over a four-week period in addition to standard medical care. Each session will last approximately 45-60 minutes and will be conducted in a controlled clinical environment by trained researchers. The control group will continue receiving standard medical care without any additional psychological or behavioral intervention.
Outcomes will be assessed at baseline and post-intervention using validated self-report instruments, including the Perceived Stress Scale (PSS), Hospital Anxiety and Depression Scale (HADS), and COPE Inventory. The primary outcome is change in perceived stress levels. Secondary outcomes include changes in anxiety, depression, and coping strategies.
Data will be analyzed using repeated measures ANOVA to examine the interaction effects between group (intervention vs control) and time (baseline vs post-intervention). Effect sizes will be reported, and statistical significance will be set at p < 0.05.
The study does not involve any investigational drugs, biologics, or medical devices, and poses minimal risk to participants.
