About

The primary aim is to identify the impacts of a behavioral intervention called "Mindfulness-Based Blood Pressure Reduction" (MB-BP) vs. enhanced usual care on the primary self-regulation target, specifically an assay of self-related processes (Multidimensional Assessment of Interoceptive Awareness) (MAIA) at 6 months, via a randomized controlled trial.

Full description

Effects of mindfulness interventions customized for prehypertensive/hypertensive patients are poorly understood. Until methodologically rigorous studies to evaluate customized interventions for hypertension are performed, it will be unknown whether the observed preliminary effects of general mindfulness interventions on blood pressure reduction could be much more effective with a tailored approach. Consequently, this study proposes to conduct a behavioral intervention study to evaluate whether Mindfulness-Based Stress Reduction (MBSR) customized to prehypertensive and hypertensive patients has the potential to provide clinically relevant reductions in blood pressure. This customized intervention is called Mindfulness-Based Blood Pressure Reduction (MB-BP). The study follows the NIH Stage Model for Behavioral Intervention Development, where targets likely proximally affected by the intervention are identified, that should also have effect on the longer-term outcomes (e.g. blood pressure, mortality). The selected targets, consistent with theoretical frameworks and early evidence how mindfulness interventions could influence mental and physical health outcomes, are measures of self-regulation including (1) attention control (specifically the Sustained Attention Response Task and Mindful Attention Awareness Scale), (2) emotion regulation (specifically the Pittsburgh Stress Battery and the Perceived Stress Scale), and (3) self-awareness (specifically the Heart Beat Detection Task and Multidimensional Assessment of Interoceptive Awareness). Based on the degree of target engagement, MB-BP can be further customized to better engage with the targets as needed.

MB-BP Intervention
Experimental group
Description:
MB-BP customizes Mindfulness-Based Stress Reduction (MBSR) to participants with hypertension. It consists of nine 2.5-hour weekly group sessions & a 7.5-hour one-day session. Content includes education on hypertension risk factors, hypertension health effects, & specific mindfulness modules focused on awareness of BP determinants such as diet, physical activity, anti-hypertensive medication adherence, alcohol consumption, & stress reactivity. Students learn a range of mindfulness skills (body scan exercises, meditation and yoga). Participants are given a home BP monitor. Participants with uncontrolled hypertension are offered to have their physicians notified; for those without a physician, the investigator works to provide access within health insurance constraints.
Treatment:
Behavioral: MB-BP
Enhanced Usual Care Control
Active Comparator group
Description:
Those in the control group receive an educational brochure from the American Heart Association (product code 50-1731) and a validated home blood pressure monitor (Omron, Model PB786N), that has an evidence-based approach to lower blood pressure. All participants who have uncontrolled hypertension (blood pressure >140/90 mmHg) will be offered to have their physicians notified, if not already being overseen for it. For participants with uncontrolled hypertension who do not have a physician, the investigator works to provide access within constraints of their health insurance. Additionally, participants randomized to the control group are asked to refrain from engaging in any type of formal mindfulness practice more than weekly during the first six months of study involvement.
Treatment:
Other: Enhanced Usual Care Control
