Course Sequence

Students in this course will be prepared for success in the psychology doctoral program at the University. Students are introduced to relevant academic communities, professional standards, and doctoral-level expectations. Essential skills needed to pursue a doctoral degree in psychology are emphasized, including critical thinking, comprehending complex scholarly texts and research articles, and effective written communications. Students will identify and begin to explore potential research topics for use in their doctoral studies and complete the course with a roadmap to navigate their way to degree completion.

This course focuses on scholarly and academic writing with an overarching goal of critically analyzing and thoughtfully synthesizing research findings while adhering to APA style and the principles of Academic Integrity. The emphases in this course are on how to (a) conduct effective literature searches; (b) critically review and summarize research studies; (c) write comprehensive, critical, and synthesized reviews of research literature; (d) formulate ideas and convey them in an ethical fashion; and (e) use feedback to revise and improve one’s work.

This doctoral-level course focuses on the fundamentals of quantitative, qualitative, and mixed methods approaches to psychological research. Students gain an understanding of the strengths and limitations of each approach, and how these methods apply to a research topic. The concepts of critical evaluating, published research, research ethics, and developing a research proposal will also be explored and practiced. In addition, it provides a foundation for subsequent research courses in preparation for successfully completing a dissertation at the University.

This course provides an introductory exploration of statistics for the graduate student. It includes instruction on the calculation, use, and interpretation of descriptive statistics, and introduces inferential statistical analysis. The emphasis of this course is on providing a working knowledge of basic statistical concepts to help the student understand statistical methodology used in psychology, and also more generally, developing a working knowledge of statistical usage in everyday life.

This doctoral course in tests and measurements provides the student conceptual as well as practical guidelines in test and scale construction. This course will expose the students to concepts and theories including: the nature of psychological constructs and concepts, measurements and measurement error, item construction and analysis, Classical Test Theory, and the different approaches to establishing instrument reliability and validity. Students will have the opportunity to apply the skills and concepts to a construct relevant to their own research interests.

This doctoral-level course will introduce the student to psychological test construction, administration and interpretation as well as current research in the area. Commonly used tests to assess cognition and personality will be studied.

This course will provide a foundation for knowledge of quantitative and qualitative research methods used in the social sciences, including psychology. Knowledge of research methods is essential both for successful completion of the dissertation and for being a skilled consumer and creator of scholarly knowledge in your field. Topics explored will include the purposes of the two basic research methods (quantitative and qualitative), the nature of multiple research designs within each method, analytic strategies used within each method, factors in quality research within each method, and ethical issues in research methods. Scholarly writing and appropriate use of the scholarly literature will also be reinforced through all topics. This course is intended to provide a broad understanding of research methods to support deeper exploration and application using more refined resources in future courses.

The purpose of this course is to acquire deeper knowledge of the quantitative and qualitative designs. The focus is on active learning to develop applied research skills that will help you in design development, data collection, and data analysis reporting phases. During the course, you will also examine how your research reflections and analysis are grounded in the empirical literature.

This course focuses on how to conduct effective literature searches, specifically in preparation for the dissertation, develop a plan for writing comprehensive, critical, and synthesized reviews of research literature, and critically review and write about underlying theoretical frameworks that lay the foundation for future research. The overarching goal of this course is for students to conduct an extensive search of the peer-reviewed empirical and theoretical literature in their topic area and identify potential areas of inquiry for their dissertation.

The Pre-Candidacy Prospectus is intended to ensure students have mastered knowledge of their discipline prior to candidacy status and demonstrated the ability to design empirical research as an investigator before moving on to the dissertation research coursework. Students will demonstrate the ability to synthesize empirical, peer-reviewed research to support all assignments in this course. The Pre-Candidacy Prospectus is completed only after all foundation, specialization, and research courses have been completed.

Students in this course will be required to complete Chapter 1 of their dissertation proposal including a review of literature with substantiating evidence of the problem, the research purpose and questions, the intended methodological design and approach, and the significance of the study. A completed, committee approved (against the minimum rubric standards) Chapter 1 is required to pass this course successfully. Students who do not receive approval of Chapter 1 to minimum standards will be able to take up to three supplementary 8-week courses to finalize and gain approval of Chapter 1.

Frequently Asked Questions

A Doctor of Philosophy (PhD) is a doctoral degree that can be awarded in various fields of study, including psychology, while a Doctor of Psychology (PsyD) is a professional degree focused specifically on psychology. The primary difference between the two is that PhD programs tend to focus on research and theoretical knowledge, while PsyD programs focus more on practical, hands-on experience.

Both PsyD and PhD degrees are highly respected and valued in the field of psychology. The choice between the two depends on individual career goals and interests. If the focus is on clinical practice and practical experience, a PsyD may be a better fit. If the goal is to conduct research and teach at the university level, a PhD may be a better choice.

The value of earning a PhD in Psychology depends on your career goals and interests. A PhD in psychology can lead to a variety of career paths, including academic research, teaching, clinical practice, and more. However, a PhD requires a high level of dedication and commitment. Prospective students should carefully consider their goals and options before pursuing a degree in Psychology.

NU graduates will be subject to additional requirements on a program, certification/licensure, employment, and state-by-state basis that can include one or more of the following items: internships, practicum experience, additional coursework, exams, tests, drug testing, earning an additional degree, and/or other training/education requirements.

All prospective students are advised to review employment, certification, and/or licensure requirements in their state, and to contact the certification/licensing body of the state and/or country where they intend to obtain certification/licensure to verify that these courses/programs qualify in that state/country, prior to enrolling. Prospective students are also advised to regularly review the state’s/country’s policies and procedures relating to certification/licensure, as those policies are subject to change.

National University degrees do not guarantee employment or salary of any kind.
