title: How some attitudes, beliefs and motivations of Spanish blood donors evolve over time.
abstract: OBJECTIVE
  To determine whether the attitudes, beliefs and motivations of blood donors evolve over time.
  
  
  METHODS
  Using questionnaires a 7-year longitudinal study of a cohort of 126 donors was performed to gather their sociodemographic characteristics and their attitudes, beliefs and motivations relating to blood donation.
  
  
  RESULTS
  Changes were observed in a large number of beliefs and attitudes, with a reduction in fear about donation and in the need for rewards and recognition, and an increase in comfort during donation and in attitudes of duty and solidarity. However, the motivations of 65% of the sample did not change.
  
  
  CONCLUSIONS
  With the passage of time, donors' attitudes and beliefs evolve in a way that is favourable to blood donation and their motivations remain stable.
