Brief Summary

This study examines the effects of a web-based motivational interview on 1) internal motivation to donate blood; 2) donor autonomy, competence and relatedness; and 3) donation intention and behavior. The study also evaluates whether group differences in donation intention and behavior are mediated by autonomy, competence, and relatedness, and in turn, internal motivation.
