Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to determine whether experiencing stress from discrimination may increase chronic kidney disease (CKD) progression in African Americans. Study participation occurs over the course of 2 days, and participant time burden is expected to be about 4.5 hours, plus a 24-hour period of wearing a blood pressure monitor.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

On Day 1, the project coordinator will explain the study to participants and answer any questions he/she may have. Those who agree to participate in the study will provide consent at the clinic and will also be asked to complete a questionnaire on an iPad in a small, private room at the clinic. The participant will complete the questionnaire alone, however, the project coordinator will read questions aloud if the participant chooses. Before leaving on Day 1, participants will fitted with a blood pressure monitor to be worn for the next 24 hours.

The clinical intervention portion of the study occurs during the morning of Day 2 (between 9:00 AM and 11:00 AM). Participants will be instructed to bring the blood pressure monitor and a list of current medications (or the actual medications) with them. First, participants will provide a urine sample and undergo blood pressure testing. A research nurse will insert a catheter (a small thin tube) into the participant's vein, and allow a 30-minute resting period so that the participant gets used to the catheter, and then take a baseline blood draw. Participants will judge how distressed they feel in that moment using a standard scale and tell the project coordinator his/her rating. Next, participants will be randomized to one of two study arms such that half will recall the racial experience and half will recall the non-racialized stressful event. An audience of two observers of same race will wear white coats and watch as the participants recall the stressful events. The research nurse will draw blood and take blood pressure measurements at multiple time points during both recall experiences. Immediately before and after each recall task, the participant will again judge how distressed he/she is feeling in that moment using the same scale as before. The project coordinator will explain the purpose of the story recall and common ways that individuals may respond to the task (such as feeling anxious after the task). A total of 100 people will take part in this study.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Of the 100 participants recruited, 80 will have a diagnosis of chronic kidney disease (CKD) and 20 will not. Participants will be randomized such that half will recall the racial experience and half will recall the non-racialized stressful event. Each participant will have an equal chance of being placed in the racialized or non-racialized experience group.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Racialized Stressful Event Recall

Participants in this study are recall a stressful event related to race.

Group Type EXPERIMENTAL

Racialized Stressful Event Recall

Intervention Type BEHAVIORAL

Participants will undergo a moderate psychological stress adapted from the Trier Social Stress Test (TSST) where they will be asked to recall a stressful, real-life, race-related event.

After instructions are provided, participants will be given two minutes to prepare their statement, and three minutes to deliver their statement. There will be an 'audience' present at each participant's speaking task which will include two observers who are of same race as the participant (African American), to heighten stress responses.

Non-racialized Stressful Event Recall

Participants in this study arm recall a stressful event unrelated to race.

Group Type EXPERIMENTAL

Non-Racialized Stressful Event Recall

Intervention Type BEHAVIORAL

Participants will undergo a moderate psychological stress adapted from the Trier Social Stress Test (TSST) where they will be asked to recall a stressful, real-life, event unrelated to race.

After instructions are provided, participants will be given two minutes to prepare their statement, and three minutes to deliver their statement. There will be an 'audience' present at each participant's speaking task which will include two observers who are of same race as the participant (African American), to heighten stress responses.
