Awareness, Acceptance, And Equanimity: Relationships Between Trait Mindfulness, Stress, And Blood Pressure, Gabrielle Renee Chin Aug 2023

Awareness, Acceptance, And Equanimity: Relationships Between Trait Mindfulness, Stress, And Blood Pressure, Gabrielle Renee Chin

Theses and Dissertations

Hypertension (HTN) is associated with stress and unhealthy emotion regulation. Mindfulness-based interventions (MBIs) are said to help address stress-related diseases like cardiovascular disease by impacting stress and emotion regulation, yet studies of MBIs on cardiovascular health show inconsistent findings. Limited research has examined the basic links between trait mindfulness and cardiovascular health, leaving the active components of MBIs in this context unclear. Therefore, the current study examined the relationship between trait mindfulness and blood pressure (BP) in individuals with pre-hypertension (pre-HTN). Latent variables representing two conceptualizations of trait mindfulness -Monitor and Accept Theory (MAT) and Equanimity- were calculated using facets …
