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 proof-of-concept study and pilot randomized clinical trial seeks to implement and evaluate a novel internet-based 5-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 randomized trial to determine whether an internet-based 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 internet-based 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.
Interventions
BEHAVIORALInternet-based Positive Psychological Intervention
The investigator's culturally-tailored internet-based Positive Psychology 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, e.g., mindfulness/meditation. The current 5-week Internet-based intervention will be delivered via a secure website which participants will access at home (or in a public setting with Wi-Fi) using an assigned username and password. The on-line program includes didactic material and home practice with participants logging into the website 3-4 times per week for 15 to 20 minute sessions. In addition to weekly on-line instruction, participants are assigned homework as a means of incorporating skills learned into their day-to-day activities.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline Ambulatory Blood Pressure at 5- and 12-weeks | Baseline, 5-, and 12-weeks | The ambulatory blood pressure monitor (the Spacelabs Healthcare 90217A ABPM) will capture 24-hour daytime and nighttime systolic and diastolic blood pressure reading in the natural environment and will capture heart rate variability. The ambulatory blood pressure monitor will record the subject's systolic and diastolic blood pressure periodically every 30 minutes to one hour and the data will be stored in the internal memory until uploaded to a companion application for visualization and analysis. In addition to ambulatory blood pressure the wearable device will record pulse waves on a beat to beat basis from which heart rate variability will be calculated and analyzed. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Life Engagement Test: Change in Baseline Life engagement and Meaning at 5- and 12-weeks | Baseline, 5-, and 12-weeks | Life Engagement Test |
| Positive Skills: Change in Baseline Positive Skills at 5- and 12-weeks | Baseline, 5-, and 12-weeks | Positive Skills |
| Medical Outcomes Study Social Support Survey: Change in Baseline Perceived Social Support at 5- and 12-weeks | Baseline, 5-, and 12-weeks | Medical Outcomes Study Social Support Survey. Four sub-scale scores are computed for 1) emotional/informational support 2) Tangible support 3) Affectionate Support and 4)Positive Social Interaction. An additional item asks the participant to quantify the number of persons of support. Sub-scale scores range from 1-5, and they are summed for a total score for perceived social support ranging from 0-25, with higher scores indicating greater perceived support. |
| Medication Adherence: Change in Baseline Medication Adherence at 5- and 12-weeks | Baseline, 5-, and 12-weeks | Medication Adherence |
| 12-Item Short Form Survey: Change in Self-Reported Mental and Physical Health at 5- and 12-weeks | Baseline, 5-, and 12-weeks | 12-Item Short Form Survey. The total score is computed. Scores range from 0-100, with higher scores indicating greater perceived physical and mental health. |
| Center for Epidemiological Studies Depression Scale: Change from Baseline Depressive Symptoms at 5- and 12-weeks | Baseline, 5-, and 12-weeks | Center for Epidemiological Studies Depression-Scale. The total score is computed. Scores range from 0-60, with higher scores indicating greater symptoms of depression. |
| Life Orientation Test-Revised: Change from Baseline Dispositional Optimism at 5- and 12-weeks | Baseline, 5-, and 12-weeks | Life Orientation Test-Revised. Two sub-scale scores are computed for affirming optimism and disaffirming pessimism. Scores range from 0-12 on each sub-scale and summed, with higher scores indicating greater optimism. |
| General Well-being Schedule: Change in Baseline Emotional Vitality at 5- and 12-weeks | Baseline, 5-, and 12-weeks | General Well-being Schedule |
| Perceived Stress Scale: Change from Baseline Perceived Stress at 5- and 12-weeks | Baseline, 5-, and 12-weeks | Perceived Stress Scale. The total score is computed. Scores range from 0 to 16, with higher scores indicating greater perceived stress. |
| Modified Differential Emotions Scale: Change from Baseline Positive and Negative Affect at 5- and 12-weeks | Baseline, 5-, and 12-weeks | Modified Differential Emotions Scale. Two sub-scale scores are computed for positive emotions and negative emotions. The sub-scales are averaged, with higher scores indicating higher positive or negative emotions. |
