[Psychological structure of personality and motivation in blood donors].

The study comprised 500 persons who donated blood for five and more times. The psychic personality structure was studied by EMOTIONS PROFILE INDEX tests with the forced-choice personality index (4) by Henry Kellerman and Robert Plutchnik. Blood donor motivation was examined by the standardized questionnaires which was interpreted by the so-called keys of desirable responses, separately for every potentially primary motive (altruism; habits; superiority complex; inferiority complex; selfpunishment; benefit; indefinite motive). The aim of the study was to assess whether the psychic structure of a personality has effects on blood donor motivation. The study has shown that: a) the psychic personality structure in repeated blood donors has effects on their blood donor motivation; b) altruism is the most common motive for blood donation in persons with the emotionally stable structures of personality and in persons with neurotic potentials; c) among persons with different psychic personality structure there are differences in the percentage of some of primary motives for blood donation. The altruism is the most common motive for blood donation found in 85% of repeated blood donors. All other motives together are found in 8% of cases while in 7% of the examines it was not possible to confirm the primary motive for blood donation.
