Positive Psychology Intervention for Spanish-speaking Hispanic/Latino Adults at Risk for Cardiovascular Disease
Study Details
Study Description
Brief Summary
The largest epidemiologic study of Hispanic/Latino participants thus far, i.e., the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) documented that 80% of men and 71% of women have at least one major cardiovascular disease (CVD) risk factor. The American Heart Association emphasizes that current CVD prevention efforts are sparse and ineffectual in minority populations and acknowledges the need for new and more effective disease prevention strategies. This observational study and pilot cluster-randomized clinical trial seeks to implement and evaluate a novel 8-week Positive Psychology (PP) Intervention (compared to an attention control condition) in Hispanic/Latino adults with uncontrolled hypertension, i.e., elevated 24-hour ambulatory blood pressure, with primary interest in testing efficacy for clinically meaningful improvements in cardiovascular function.

Detailed Description
The study features piloting of a cluster-randomized trial to determine whether a positive psychology (PP) intervention is associated with greater improvements in blood pressure compared to an attention control condition. The pilot trial additionally evaluates the efficacy of the PP intervention with respect to psychological well-being, hypertension-related health behaviors, autonomic cardiac control, and high-sensitivity C-reactive protein. Serum blood assays will facilitate exploration of mechanistic indicators linking psychological well-being to cardiac functioning.

| Experimental: Positive Psychological Intervention Our culturally-tailored Positive Psychology (PP) Intervention is a non-pharmacotherapy approach aimed at increasing positive emotional experiences by teaching individuals to engage in intentional activities known to increase psychological and emotional well-being through targeting of constructs such as optimism, gratitude, mindfulness/relaxation, and resilience. |

Outcome Measures
Primary Outcome Measures
- Change from Baseline Ambulatory Blood Pressure at 8- and 12-weeks [Baseline, 8-, and 12-weeks]
The device, Vitavue, consists of a wireless microcontroller that connects to a desktop computer running proprietary software when operated in real time connected mode. Alternatively, it can be operated in standalone unconnected mode by logging acquired data to an internal memory storage device. The device contains a number of sensors including ECG single channel amplifier, Multispectral Photodiode to record photo pulse plethysmograms, temperature sensor to measure skin temperature, and an accelerometer to record the level of activity.
Secondary Outcome Measures
- Center for Epidemiological Studies Depression Scale (CESD): Change from Baseline Depressive Symptoms at 8- and 12-weeks [Baseline, 8-, and 12-weeks]
Center for Epidemiological Studies Depression-Scale
- Life Orientation Test-Revised (LOT-R): Change from Baseline Dispositional Optimism at 8- and 12-weeks [Baseline, 8-, and 12-weeks]
