A. How Siblings Cope With Bone Marrow Transplants

Narrator: This is Science Today. It's been found that sibling donors for pediatric bone marrow transplants, often suffer more anxiety and lower self-esteem than non-donor siblings. Dr. Mary Crittenden, a psychologist at the University of California, San Francisco, directed a study which, for the first time, looked into the emotional health of the child donor.

Crittenden: Donors, as a group, reported feeling more anxiety and having lower self-esteem than the non-donor sibs. Now, that's kind of a striking finding. It's not surprising to think anxiety. You've gone through a procedure needless to say, you will have some effect. You're a human being and anxiety is a very normal reaction.

Narrator: But Crittenden warns these findings are based on group data.

Crittenden: This doesn't mean that every sibling who gives bone marrow or every sibling who doesn't, is going to experience this, but we found this in the study, so it's a thing we want to pay a little attention to.

Narrator: Crittenden hopes more attention will be given to the donor from both parents and doctors. For Science Today, I'm Larissa Branin.
