The role of motivation and the regulation of eating on the physical and psychological health of patients with cardiovascular disease.

This study tested a longitudinal motivation model for healthy eating in patients with cardiovascular disease, using self-determination and social-cognitive theories. A total of 513 patients completed measures of eating habits, global motivation, motivation for eating, self-efficacy for eating and life satisfaction, immediately after a major cardiac incident and at three times during a year (e.g. 2008-2009). Physiological indicators were measured to examine how they predicted the participants' physical health. Results found participants with self-determined motivation were more likely to develop a sense of self-efficacy towards eating and a healthy diet, which had beneficial effects on their physical health and life satisfaction.
