Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to better understand the potential value of reducing stress to ameliorate a cluster of biological and behavioral factors implicated in cardiovascular disease (CVD) risk. These factors include psychological distress, poor sleep quality, and exaggerated physiological responses to emotional stress. Results will be used to develop an innovative brief intervention to reduce risk for CVD by improving sleep quality, ameliorating psychological distress, and attenuating stress physiology.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will be conducted among 200 men and women participating in 8-week Mindfulness-Based Stress Reduction (MBSR) classes at Duke Integrative Medicine in Durham, North Carolina. The central hypothesis of this NIH-funded clinical trial (R00 AT004945, PI: Greeson) is that mindfulness meditation training is associated with increased levels of mindfulness and improved cognitive-emotional functioning that, together, are associated with reduced psychological distress, improved sleep quality, and less exaggerated physiological responses to emotional stress, including blood pressure and inflammation. This study is designed to examine psychological and biological mechanisms that may explain individual differences in MBSR outcomes. This knowledge is important because it will help us better understand who is most likely to benefit from mindfulness meditation training, and why. The results from this study are expected to elucidate mechanisms underlying the mental and physical health benefits of stress reduction, which can help guide clinicians in referring the most suitable patients to local MBSR programs.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Meditation

Both arms will undergo 8-weeks of Mindfulness-Based Stress Reduction (MBSR) training. The experimental arm will be randomly assigned to practice meditation immediately following the emotional stress task in the lab during the post-MBSR lab visit.

Group Type EXPERIMENTAL

Mindfulness Based Stress Reduction (MBSR)

Intervention Type BEHAVIORAL

The MBSR program consists of 8 weekly classes that last for 2.5 hours each and a commitment to daily meditation practice for the duration of the course. Classes include didactic instruction on mindfulness and its relationship to stress and health, guided meditation practices, and group discussion. Mindfulness meditation practices include awareness of breathing, awareness of emotions, body scan, mindful hatha yoga, mindful walking, mindful eating, mindful listening, and lovingkindness (metta). Participants are expected to practice formal meditation outside of class for 20-45 min per day, 6 days per week. In addition, participants are encouraged apply mindfulness to everyday activities like eating, communicating with others, and hobbies. Written materials and audio CDs with guided meditations and yoga are provided. The course also includes one full day (7-hours) of meditation on a Saturday following the 6th week of class.

No meditation

Both arms will undergo 8-weeks of Mindfulness-Based Stress Reduction (MBSR) training. The active comparator arm will be randomly assigned to not practice meditation, but rather listen to a non-meditative audio track of equal length, immediately following the emotional stress task in the lab during the post-MBSR lab visit.
