Exploring the Use of the Stages of Change Model to Increase Organ Donations Among African Americans

Abstract

The success of organ transplants is affected by the degree of antigen match between donor and recipient. With organ transplants among African Americans, finding a good antigen match is difficult. While the consent rate for organ donations among Caucasians is 50%, this rate among African Americans is only 12%. The resulting ratio of donors to “recipients” is 1 to 9 in African Americans. The majority of organs received by African Americans come from Caucasian donors, thereby reducing the probability of an antigen match and increasing the probability of organ rejection. These circumstances could be improved if the organ donation rate eamong African Americans was increased. There is some empirical support for the theory that behavior change occurs through identifiable stages. This paper presents evidence for the construct validity of a stage of change measure suitable for use in designing and evaluating attempts to promote organ donations in the African American community. Use of this measure also permits clinicians to assess how receptive a client will be to organ donation promotional material. Use of this measure offers the possibility of refining approaches to organ donations among African Americans. Increases in the donor rate will result in a larger pool of antigen compatible organs in this subpopulation.
