Primary Outcome Measures

Name	Time	Method
Change in Blood pressure	Measured at baseline and 6 months and 12 months after start of the intervention	The primary outcome is systolic blood pressure at 6 months post start of the intervention. The Omron digital blood pressure monitor will be utilized to measure blood pressure (Omron Healthcare, Inc., Lake Forest, IL). The participant will sit quietly for \>5 minutes, 3 readings will be taken 1-2 minutes apart while seated, and an average of the last 2 readings will be taken to evaluate blood pressure.

Secondary Outcome Measures

Name	Time	Method
Change in Medication adherence	Measured at baseline and 6 months and 15 months after start of the intervention	Medication adherence will be measured using the 15-item Adherence to Refills and Medications Scale (ARMS). The items are evaluated on a 4-point scale ranging from "none of the time" to "all of the time".
Change in DASH diet adherence	Measured at baseline and 6 months and 15 months after start of the intervention	Adherence to the Dietary Approaches to Stop Hypertension (DASH) diet will be measured using the food frequency questionnaire developed by Viocare (Princeton, NJ). This 156-item graphical, web-based FFQ queries respondents about usual intakes of 156 food and beverage items over the past three months. It also provides food and nutrient analyses to the research team based on the Nutrition Data System for Research 2018 (NDSR, University of Minnesota, Minneapolis, MN).
Change in Self efficacy	Measured at baseline and 6 months and 15 months after start of the intervention	Self efficacy will be measured using the Hypertension Self-Care Profile Self-efficacy scale which evaluates self efficacy for 8 common self care recommendations for individuals with hypertension. The items are evaluated on a 4-point scale ranging from "not confident" to "very confident".
Change in Social support	Measured at baseline and 6 months and 15 months after start of the intervention	Social support for eating a healthy diet will be measured using a 4-item questionnaire which will evaluate the participant's perception of social support received from family members, friends, church members, and their Pastor. The items are evaluated on a 5-point scale ranging from "never" to "always".
Change in Quality of life	Measured at baseline and 6 months and 15 months after start of the intervention	Quality of life will be measured using the EuroQual (EQ-5D-5L) questionnaire. The measure evaluates the participant's perception of their "health today" with respect to mobility, self-care, usual activities, pain/discomfort, and anxiety depression. The items are evaluated on a 5-point scale ranging from "no problem" in the area to "extreme problem" in the area.
Change in Hypertension knowledge	Measured at baseline and 6 months and 15 months after start of the intervention	Hypertension knowledge will be evaluated using a 10-item questionnaire adapted from the Hypertension Evaluation of Lifestyle and Management (HELM) Knowledge Scale. Systolic and diastolic blood pressure measurements will be evaluated using the following 4 categories: high, low, normal, and don't know. The frequency with which medication should be taken, lifestyle factors associated with hypertension, and health risks associated with hypertension will also be evaluated.
Change in Nutrition knowledge	Measured at baseline and 6 months and 15 months after start of the intervention	Nutrition knowledge will be evaluated using an 18-item survey adapted from the International Food Policy Study 2020 - United States Survey. Common foods and food labels are evaluated on a 10-point scale ranging from "not healthy at all" to "extremely healthy".
Change in Barriers to medication use	Measured at baseline and 6 months and 15 months after start of the intervention	Barriers to medication use will be measured using the 15-item BRIGHT study Barriers to Medication Scale. The scale evaluates different reasons why it is difficult for participants to take medications or to take the medications on time. The items are evaluated on a 5-point scale ranging from "never" to "all the time".
