The following secondary exploratory hypothesis related to patient-level outcomes will be evaluated: The HAT program will have a positive impact on behavioral and cognitive factors that play an important role in the process of patient self-management, including hypertension treatment self-efficacy, health locus of control, health beliefs, and hypertension knowledge. Researchers will also investigate the impact of HAT on patients' compliance with multi-component treatment plans (including adherence to medication regimens and therapeutic lifestyle changes) and explore the effect of the HAT system on patients' ability to reach dietary, physical activity, weight control, and sodium consumption goals recommended by the JNC 7 Report.
