Long Term Minor Sibling Donor Well-Being

FOR PARENT or Legal Guardian: Half of the young persons being asked to participate in this study will be donating bone marrow or stem cells and will be referred to as "minor donors." The other half will not be donating marrow or cells but have a sick family member who will be having a bone marrow or stem cell transplant and will be referred to as "non-donors". For each participating young person, one parent or legal guardian will need to complete the parent questionnaires as well. You are being asked to participate in this study because you have a sick family member who will have a bone marrow or stem cell transplant at this hospital and you are a caregiver to a healthy child. You will be asked to complete 5 questionnaires shortly before the bone marrow or stem cells are collected, shortly after the transplant, and 6 months after the transplant. You will be asked about your children, family atmosphere, and parental well-being. Most of the questions have a list of possible answers, and you will choose the answer that best describes you. Some questions are left blank for you to write in your answer. It will take about 45 minutes to complete the questionnaires. FOR CHILD: If you agree to take part in this study, you will be asked to complete 9 questionnaires shortly before the bone marrow or stem cells are collected, shortly after the transplant, and 6 months after the transplant. You would be asked about your feelings, behavior, and how you are doing in school. These types of questions do not have wrong answers. Most of the questions have a list of possible answers, and you will choose the answer that best describes you. Some questions are left blank for you to write in your answer. It will take about 1 hour to fill out the questionnaires. Length of Study: You will participate in the study across a 7 month period. You will begin the study one month before donation and complete the study 6 months after the donation. This is an investigational study. Up to 30 participants (15 minor donor's parents and 15 non-donor's parents) will be enrolled on this study. All will be enrolled at M. D. Anderson.
