Study Arms:
- 1 (Type: EXPERIMENTAL): Meditation training group-- received Mindfulness Based Stress Management from the Penn Program for Stress Management.~The meditation practice initially emphasized attention to a single focus. For most concentrative exercises, this focus was the breath. The sensations of breathing were to be examined closely, and when attention wandered it was to be redirected back to the breath. In other exercises, the focus of attention was to be directed to sensations within specific body parts (body scan exercise) and sensations of walking (walking meditation). During the 5th week of classes, the mindfulness training was expanded to include some explicit training in receptive attention.
- 2 (Type: ACTIVE_COMPARATOR): Nutrition education group~An active comparison condition involving nutrition education was offered. This course matched the mindfulness course in all dimensions including course duration, homework, psychosocial support, and teacher expertise. The course was taught by a nurse who had expertise in nutrition and offered a program described in the book, Nutrition for Life by Lisa Hark.
