To test the efficacy of MBSR, patients will be randomly assigned to one of three groups. The MBSR condition will be provided training in mindfulness meditation methods. The patient education control group will be provided information about CAD in a didactic format. This condition will control for the nonspecific effects of contact in a therapeutic setting. Excluding intervals spent in personal meditation practice in the mindfulness meditation condition, the length of sessions in the two intervention conditions will be approximately equal. The third group, a stress-monitoring usual care control condition, will control for the effects of symptom measurement reactivity in patients receiving routine medical care.
