Technology-based Intervention and Positive Psychological Training for Blood Pressure Control in African Americans

Completed · Not applicable

Conditions studied: Hypertension, Self-management, Technology

In brief

The purpose of this pilot study is to evaluate the effects of a theoretically-derived technology-based intervention (called TechSuPPorT) and its associated neurological mechanisms for hypertension self-management in African Americans. The investigators will compare two intervention arms in this study, the Technology-Based Component Only arm (comparison group) and the TechSuPPorT arm (intervention group) in 20 African Americans with uncontrolled hypertension. We aim to: 1. Determine whether there are differences in blood pressure (BP), health-related quality of life (HRQoL), and psychological health (affective well-being, depressive cognitions, anxiety) betweenTechSuPPorT and the Technology-based Component only arm. 2. Determine whether there are differences in self-management behaviors (medication adherence, diet, exercise, self-monitoring BP) between the two groups. 3. Examine whether self-efficacy, decision-making, motivation, patient activation, and perceived stress, and positive emotions mediate the relationship between the interventions and self-management behaviors. 4. Determine if social support, demographics (age, gender, education), discrimination, and technology utilization moderate self-management behaviors, BP, HRQoL, and psychological health. 5. Explore differences in neural processing (diffusion tensor imaging \[DTI\]/ task positive network \[TPN\] task-differentiation), and stress response (cortisol and inflammation panel) between the two groups.
