All students must complete an empirical dissertation as part of the Psy.D. degree. The dissertation represents the culmination of the students' scientific training and reflects competence in the ability to conceptualize, design, enact, describe and disseminate an empirical project. The School of Psychology requires that the dissertation be the students' own work, under the guidance and direction of the dissertation chair. Options for the dissertation include but are not limited to: original research investigation, program evaluation projects, and development and empirical evaluation of a new assessment or intervention technique. The common theme to all dissertations, however, is expansion of the student's understanding of the knowledge base of psychology, as well as scholarly competence and knowledge of research design and analysis.
