Arm Intervention/treatment
Experimental: Early Intervention, MBSR therapy
Group that receives Mindfulness Based Stress Reduction Therapy immediately after randomization
 Behavioral: Mindfulness Based Stress Reduction (MBSR) Therapy
The objectives of MBSR therapy are to 1) understand their personal response to stress and 2) develop techniques to change the way these patients respond and cope with stress
Other Names:
  • stress reduction therapy
  • Jon Kabat-Zinn
  • mindfulness meditation
Active Comparator: Delayed Treatment Arm, MBSR Therapy
Group that receives Mindfulness Based Stress Reduction Therapy within 3 months of randomization
 Behavioral: Mindfulness Based Stress Reduction (MBSR) Therapy
The objectives of MBSR therapy are to 1) understand their personal response to stress and 2) develop techniques to change the way these patients respond and cope with stress
Other Names:
  • stress reduction therapy
  • Jon Kabat-Zinn
  • mindfulness meditation


Outcome Measures

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. The primary outcome is the difference in 24-hour systolic and diastolic blood pressure between the treatment and wait-list group for the 12-week primary assessment period. [ Time Frame: 12 weeks ]

Secondary Outcome Measures :
  1. Changes in 24 hour ambulatory systolic and diastolic blood pressure at the end of the treatment assessment period compared to the beginning. [ Time Frame: 12 weeks ]
  2. Between and within group comparisons of MBSR on blood pressure at different times of the day including daytime, night time and work time. [ Time Frame: 24 weeks ]
  3. The proportion of patients achieving blood pressure targets (24-hour ABPM<130/80 mmHg, daytime ABPM<135/85 mmHg) at the end of the Primary Outcome period [ Time Frame: 24 weeks ]
  4. The effect of MBSR on ambulatory blood pressure by gender [ Time Frame: 24 weeks ]
