Identifying belief targets to increase bone marrow registry participation among students who have never donated blood.

New members on bone marrow registries worldwide are needed to allow sufficient diversity in the donor pool to meet patient needs. We used the theory of planned behaviour belief-basis and surveyed students who had not donated blood previously (i.e. non-donors) (N = 150) about the behavioural, normative, and control beliefs informing their intentions to join the Australian Bone Marrow Donor Registry. Key beliefs predicting non-donors' intentions included: viewing bone marrow donation as an invasion of the body (β = -.35), normative support from parents (β = .40), anticipating pain/side effects from giving blood (β = -.27), and lack of knowledge about how to register (β = -.30). Few non-donors endorsed these beliefs, suggesting they are ideal targets for change in strategies encouraging bone marrow donor registration.
