The relationships between burnout, stress, and social support have been evaluated across a number of populations within the helping professions. However, no published studies have addressed the relationships between the aforementioned variables among doctoral students in psychology. As a result, the current study attempted to expand knowledge of the relationships between burnout, stress, and social support specifically among Clinical, Counseling, and School Psychology doctoral students. Results suggested that Clinical, Counseling, and School Psychology doctoral students are generally similar in their reports of burnout, stress, and social support. However, several differences were observed between the groups, and these differences are reported. The direct influence of stress on burnout was supported. Minimal support was observed for the direct influence of social support on burnout. Limited support was observed for the moderating or buffering effect of social support on the stress-burnout relationship. Implications of research findings for practice are evaluated. Additionally, recommendations for future research are provided. I am fortunate to have many supportive individuals in my life who consistently encourage, challenge, console, inspire, and comfort me, and generally add color to my life. As a result, I wish to thank a number of individuals for the support, guidance, and friendship they have offered to me specifically during the completion of this dissertation. First, I wish to thank my classmates, Brian, Jan, Justin, Larry, Lynn, and Heather. I am grateful for their support, humor, and encouragement, in spite of their own personal and professional challenges. Second, I wish to thank my lifelong friends, Denise and Erin, and more recently established friends Sarah, Becky, Julie, and Vicki for their patience, assistance, and consistent encouragement throughout the dissertation process. Thank you to my faculty advisor and dissertation chair, Dr.
