A large amount of empirical material has been accumulated with respect to the attitudes to and determination of such type of prosocial behavior as a donation of blood as well as effective interventions to attract and retain donors. The aim of our work was to systematize and synthesize the data obtained in empirical studies and to build a single model that takes into account both factors of different levels and heterogeneity of the donation itself as a socio-psychological phenomenon.
