Participants answered 21% of marrow donation knowledge questions correctly, and higher knowledge and lower ambivalence were related to a greater likelihood of joining the NMDP. The emotional appeal increased the likelihood of registering more than the rational appeal. Race did not moderate the response to the intervention condition. Future studies seeking to increase participation by diverse young adults should target knowledge and emotional aspects of the need for donors.
