The paper deals with the results of an investigation focused on motivation for non-remunerated Blood Donation which were obtained by enquiries in a group of 400 blood donors in the Cheb District Transfusion Station. The clients were asked to give three reasons why they are blood donors. The most frequent motive was an effort to help sick people. This motive was mentioned by almost all respondents and accounted for one third of all given motives. Other motives suggested possible differences between donor groups by sex, age and occupation. A strong motive was a check of the health status before blood collection, „fatality“, i.e. admission of the possibility that the donor may one day be in a position to need blood and the feeling of paying a debt, because the donor or somebody of his close relatives or friends needed blood in the past. Medium strong motives in young people regardless of sex and in the group of women was the desire to attain self-respect by a noble deed: in men a stronger motive was one day off with full pay. Very weak were motives such as gaining respect of the partner, respect of other people, tax reductions for each batch of donated blood and advantages offered to donors by insurance companies. The investigation was made in an attempt to help public relations workers to elaborate materials and to increase the effectiveness of communication with potential donors.
