Religiosity and religious coping in patients with cardiovascular disease: change over time and associations with illness adjustment.

Little is known about the longitudinal relationship between religiosity/spirituality (R/S) and patient physical and mental health in patients with cardiovascular disease. Forty-three patients with a first-time myocardial infarction or coronary artery revascularization bypass surgery completed measures of religiosity, religious coping, quality of life (QOL), and weight prior to a cardiac rehabilitation program and 1 and 2 years later. R/S changed over time; the direction of the change varied by type of R/S. Increases in religiosity were associated with increases in weight and QOL; increases in religious coping were associated with decreases in weight and increases in QOL.
