Several of these committee members met with me on multiple occasions to teach me new statistical procedures and ensure that this dissertation was scientifically valid and completed to the best of my abilities. I want to especially thank Dr. Brad Nakamura, my advisor, for his dedication in my development as a scientist. Dr. Nakamura's support, encouragement, and motivation greatly influenced the progress and completion of this dissertation.My sincerest thanks are also given to Hilary Gould, Kaitlin Hill, Priya McLennan, Albert Mah, and Amanda Vincent for their support with edits and consultation. Additionally, I would like to extend my appreciation to the therapists and youth in Hawai'i's Child and Adolescent Mental Health Division, who completed and allowed for the collection of data that comprised my archival analyses. I hope that my analyses will help with large scale quality improvement efforts for Hawai'i's youth mental health system. Lastly, I would like to thank my family and my partner for all of the emotional support that they provided me during this challenging process.
