Predicting first lifetime plasma donation among whole blood donors




The aim of the study was to predict a first lifetime plasma donation among whole blood donors.

Study Design and Methods

A sample of 252 whole blood donors, who never donated plasma, completed the study questionnaire assessing intention, attitudes, subjective norm, and perceived behavioral control toward giving plasma. The dependent variables were intention to give plasma and first lifetime plasma donation within 6 months.


At 6 months, 57 individuals had made 98 plasma donations. First lifetime plasma donation was predicted by intention (p < 0.05) and age (50+ years, p < 0.05). Intention was determined by attitudes (p < 0.001) and perceived behavioral control (p < 0.001).


Promotional strategies to recruit new plasma donors should target individuals aged 50 years and more. Such strategies should be coupled with actions to lower the perceived barriers and highlight the perceived advantages of becoming a plasma donor.
