Abstract
This study aimed to investigate the mediating role of spiritual health in the relationship between ego-strength and adjustment to heart disease. In total, 327 patients with coronary artery disease (138 women, 189 men) completed the Ego-Strength Scale, Adjustment to Illness Scale, and Spiritual Well-Being Scale. Results showed that both ego-strength and spiritual health had a significantly positive correlation with adjustment to heart disease. Results also revealed that spiritual health mediated the relationship between ego-strength and adjustment to heart disease. More improvement in adjustment to heart disease requires more improvement in patients' spiritual health as well as to ego-strength.
