Blood donors and their changing engagement in other prosocial behaviors.

This study provides new insights into blood donors' prosocial behavior. While most previous studies neglected blood donors' engagement in other prosocial behaviors, this study highlights the fact that blood banks need to be aware of blood donor switching behavior between all prosocial behavior forms. As most blood banks also are providing other types of donations forms, they can use this knowledge and cross-recruit blood donors to engage in other forms of prosocial behavior.
