This study aims to determine the factors affecting exercise adherence in patients with coronary artery disease (CAD). For this purpose, the following measurement tools will be used respectively: (1) "Patient Information Form" including sociodemographic characteristics of the patients and medical information related to the disease, (2) the Exercise Adherence Rating Scale (EARS), (3) Exercise Self-Efficacy Scale (ESE) and, (4) Turkish-Health Literacy Survey Europe-Q12 (HLS-EU-19-12Q-TR). Statistical analyses will be carried out by descriptive statistics (number, percentage, mean, standard deviation, etc.), correlation analysis and regression analysis.

Coronary Artery Disease (CAD) is the most common form of cardiovascular disease in the world and is one of the leading causes of mortality and morbidity in Turkey and worldwide. Exercise training is very important in the treatment of CAD because of its various cardiovascular benefits. However, most patients have been shown to have low to moderate adherence rates to the recommended exercise prescription. The results of a limited number of studies show that the factors affecting exercise adherence in patients with CAD need to be supported by new studies. This study aims to determine the factors affecting exercise adherence in patients with coronary artery disease (CAD). The study will be conducted with CAD patients followed up in the cardiology clinics of a tertiary care hospital in northern Turkey. A cohen's d will be calculated using preliminary data from 20 patients using Exercise Adherence Rating Scale (EARS), and an adequate sample size will be determined with a 95% confidence interval, a bias level of 0.05, and 80% power. Patients with a diagnosis of CAD confirmed by a physician at least one year ago, who have been recommended any exercise/physical activity by a physician according to article 1 of EARS, who are ≥18 years old and <75 years old, and who have the ability to understand and speak Turkish will be included in the study. The data will be collected using the following measurement tools respectively: (1) "Patient Information Form" including sociodemographic characteristics of the patients and medical information related to the disease, (2) the Exercise Adherence Rating Scale (EARS), (3) Exercise Self-Efficacy Scale (ESE) and, (4) Turkish-Health Literacy Survey Europe-Q12 (HLS-EU-19-12Q-TR). Statistical analyses will be carried out by descriptive statistics (number, percentage, mean, standard deviation, etc.), correlation analysis and regression analysis.

Inclusion Criteria:

• A diagnosis of CAD confirmed by a physician at least one year ago,
• Individuals who have been recommended any exercise/physical activity by a physician according to item 1 of the EARS,
• Turkish comprehension and speaking skills.

Exclusion Criteria:

• Presence of serious physical and mental health problems,

The study population refers to adults with coronary artery disease.

Participant data will not be shared openly with other researchers due to the confidentiality of personal data. The primary investigator of the study can be contacted for data sharing.
