Intervention type: BEHAVIORAL
Group type: ACTIVE_COMPARATOR
Intervention: Financial reward
Description: In contingency management, financial rewards are contingent upon an individual changing behavior. In our study, financial incentives are contingent upon group behavioral changes.. In the intervention phase participants will be randomly assigned to one of the three treatment arms and they will receive the financial incentive that corresponds to their treatment arm. Data will be collected for four months and all participants will continue receiving a compensation for participation

Group type: ACTIVE_COMPARATOR
Intervention: Social norms
Description: To build social norms the study adds a group component to a contingency management model. In contingency management, financial rewards are contingent upon an individual changing behavior. Social norms are expected to emerge as a result of the designed group contingency management, monthly-facilitated meetings at a local clinic, and daily basis interaction through social media. The intervention will build social norms that improve medication adherence of each member of a group. A three-arm randomize trial is designed to test this hypothesis. Hypertensive patients will be randomly assigned to a group contingency management (GCM) arm, an individual contingency management (ICG) arm, or a control arm.

Intervention: Medication adherence assessment
Description: Participants will be informed that they will receive and learn how to use eCap, a medication event monitoring system that participants will return after completing the study. The project nursing student will count the number of pills the participant currently has and make a record of it on the Data Collection form.The participant will provide the project nursing student with his/her antihypertension prescription records so that the dosage amount and number of pills can be recorded on the Data Collection form.
