The trial was part of the Collaborative Projects on Minority Health, an Institute- initiated program to foster collaborative clinical research that focused on new and improved approaches for diagnosis, management, and prevention of cardiovascular, lung, and blood diseases in minorities. The trial was part of a two-grant collaboration on Nonpharmacologic Treatments for Managing Hypertension in African American Adults. Ernest Johnson (R01HL50516),the Program Coordinator collaborated with Robert Schneider (R01HL51519). The objectives of their studies were complementary and the collaborative arrangements allowed them to determine the effectiveness of different approaches to stress management in comparison with a control group that was comparable at both sites. In addition, the treatment schedules in both studies resulted in identical contact time, length of interventions, expectations regarding treatment effectiveness, and follow-up assessment periods. As a result, a considerable degree of pooling of data for analysis was possible.
