This study investigated the impact of a new stress management program on physiological and psychological stress and health risk factors among 75 correctional officers. The experimental group received training in emotion self-regulation techniques intended to reduce stress and health risk factors. Practice of the techniques was enhanced by heart rate variability feedback, which helped participants learn and sustain use of the self-management tools. Measures of physiological stress included cortisol, DHEA, cholesterol, triglycerides, fasting glucose levels, 10-min resting electrocardiogram, heart rate variability, and blood pressure. Three psychological questionnaires assessed emotional stress and work-related variables. There were significant improvements in the experimental group in cholesterol, glucose, heart rate, blood pressure and positive outlook and significant reductions in overall psychological distress. There were significant increases in productivity, motivation, goal clarity, and perceived support. The mean difference between pre-and post-intervention projected health care costs was calculated to be $1,179 per employee per year.

This study examined the effect of the Ornish Program for Reversing Heart Disease and cardiac rehabilitation (CR) on psychosocial risk factors and quality of life in patients with confirmed coronary artery disease. Participants had previously undergone a revascularization procedure. The 84 patients self-selected to participate in the Ornish Program for Reversing Heart Disease (n = 507 28), CR (n = 28), or a control group (n = 28). Twelve psychosocial risk factors and quality of life variables were collected from all three groups at baseline, 3 months, and 6 months. At 3 and 6 months, Ornish group participants demonstrated significant improvements in all 12 outcome measures. The rehabilitation group improved in 7 of the 12, and the control group showed significant improvements in 6 of the variables. Intensive lifestyle modification programs significantly affect psychosocial risk factors and quality of life.
