This dissertation is dedicated to my family, who provided me unconditional support and love during this journey through my doctoral education: my children, David, Laura and John and my husband, Paul. v Acknowledgements There are so many people to whom I am very grateful for their assistance, support and mentoring during my doctoral education. I am especially thankful to the following individuals: Dr. Roberta Rehm, my faculty advisor and dissertation chair, whose wisdom and gentle guidance has been invaluable. She was constantly encouraging and teaching me. She spent immeasurable time sharing her knowledge and teaching me about qualitative research, family research and its application to pediatric nursing. She was instrumental in my successful grant applications to the National Institutes of Health/National Institute of Nursing Research and the American Cancer Society. I am humbled to have been her student over the past few years and aspire to be like her in the future. Dr. Linda Franck, chair of my qualifying exam, challenged me to look at my research through a broader lens. Her vast research experience set the bar high, which I strove to reach, and hope I did. She provided incredible mentorship and increased my understanding of the research process. Dr. Bonnie Halpern-Felsher, whose enthusiasm and knowledge of AYAs was critical for my dissertation. Thank you for sharing not only your expertise about AYAs, but also allowing me to participate in your lab meetings and learning from your wonderful staff. Dr. Robert Goldsby, whose long-time experience in pediatric oncology and especially in the area of AYAs helped to guide me. He kept the study grounded in reality, with a practical focus on research and the care of these patients. I was fortunate to learn so much from each of my committee members. Thank you for your time, expertise and patience. vi To the many members of the oncology team who enthusiastically supported this work in so many ways to move the science forward: Pam Simon, NP, Christie Chaudry, NP, Dr. Sheri Spunt MD, and the staff at both Lucile Packard Children's Hospital Stanford and Benioff Children's Hospital. I could not have done this work without your warm welcome and enthusiasm for me to conduct this research at your respective institutions. I felt supported and encouraged by your advice, words of encouragement, and assistance with the recruitment of participants. Finally, to the AYAs who participated in this study, it is with deep gratitude that I thank you for sharing your stories. You have taught me so much and I will never forget you.
