Supplementary materials for: Social Support and Adherence to Self-Care Behavior among Patients with Coronary Heart Disease and Heart Failure: A Systematic Review

Cardiovascular diseases stand out as the foremost cause of mortality on a global scale and encompass conditions that require long term self-care. Coronary heart disease and heart failure are two cardiovascular conditions that require significant lifestyle modifications. Adherence to self-care is a multifaceted phenomenon, and is influenced by various factors that include social, economic, disease-related and healthcare system-related factors. A key factor in adherence to self-care in chronic illnesses is social support. To explore this relationship between social support and adherence to self-care, a systematic review was carried out across Scopus, EBSCO host and ProQuest from October 2022 to February 2023 using predefined search criteria. Studies from inception to February 2023 were considered for the review, ultimately incorporating a total of 11 studies. Six studies had an adult population with coronary heart disease while the remaining five had adults with heart failure. All the studies reported a significant positive correlation between social support and adherence to self-care. Our findings revealed that social support plays a significant role in promoting self-care, emphasizing the need for a holistic understanding of self-care to develop effective interventions. Along with self-report measures, objective measures should be used to assess adherence accurately. There is a need for scales that assess all aspects of self-care, as well as the development of new interventions and teaching strategies to facilitate the individual’s self-care journey. In addition, family members and trusted resources should be involved in encouraging self-care, and interventions should target both patients and their family members.
