Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Participants will be recruited through the Psychology Subject Pool, which will then link students to the study measures in an online survey. Participants will be asked their age to confirm eligibility to participate (students must be between 18-35), and eligible students will be presented with the consent form through the online survey system. Participants will then be asked to complete measures of demographic information, personality/psychological characteristics, and transplant-related knowledge, intentions, and attitudes. All participants will then be given background information on bone marrow transplants.
Randomization: Students will be randomized by sex in the online survey system to the emotional presentation condition or the rational presentation condition. The emotional condition will tell the story of a fictional pediatric patient with cancer who needs a transplant. The rational condition will describe the facts about the need for diversity in the registry.
After being presented with the rational or emotional appeal, participants will again be asked about their intentions to register, their motivations for registering, and their mood.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Emotional Group
Participants will be randomly assigned to receive an emotional or rational appeal, stratified by sex.
Emotional Appeal
Participants will be presented with a short vignette about a child undergoing cancer treatment and needing a bone marrow transplant in order to survive cancer.
Rational Group
Participants will be randomly assigned to receive an emotional or rational appeal, stratified by sex.
Rational Appeal
Participants will be presented with data regarding the importance of considering race/ethnicity when looking for a bone marrow transplant donor and the likelihood of finding a match based on the patient's racial/ethnic background.
