I would first like to thank my wife and best friend, Katie, who has made countless sacrifices, and has helped me navigate the complex challenges of graduate school. I would also like to thank my parents, brother, and extended family members for their endless love and support, and for inspiring me to serve others and encouraging me to follow my dreams. There are also several professional mentors that I would like to acknowledge. First, I would like to thank my dissertation advisor, Dr. Paul J. Rosen, who has pushed me to become a better scientist, and whose expertise in emotion regulation and peer victimization has been critical to helping me build my program of research. In particular, his initial theoretical conceptualization of the relation between emotion regulation and peer victimization helped lay the groundwork for much of my work in graduate school, and culminates with this dissertation project. I would also like to thank Drs. Brendan E. Depue and Janet Woodruff-Borden for their advice, guidance, and mentorship throughout graduate school; they have been instrumental in my development as both a researcher and clinician. Additionally, I would like to thank Drs. Cheri A. Levinson and Jeffrey C. Valentine for taking time to serve on my dissertation committee, and for providing thoughtful feedback and improving the quality of my dissertation project. Lastly, I would like to say thank you to Dr. Stephen P. Becker for his dedication to my training and his guidance on my v dissertation project, and William Gardner for helping me make this dissertation project possible. I would also like to thank my research mentors over the years (Drs. José A.
