Doctoral nursing programs end with a large piece of scholarship, but a DNP project and a PhD dissertation are built for different purposes. This guide explains the difference, lays out the chapters, and shows what a strong purpose statement looks like.
A Doctor of Nursing Practice (DNP) program prepares you to lead and improve practice, so the final project usually translates existing evidence into a real setting and evaluates the result. A PhD in nursing prepares you to be a scientist, so the dissertation generates new knowledge through original research. Both need rigor and a committee, but their questions and goals differ. The American Association of Colleges of Nursing publishes the standards that shape DNP programs; your own handbook will tell you what your institution expects.
| Feature | DNP scholarly project | PhD dissertation |
|---|---|---|
| Main aim | Improve a practice, process, or outcome | Create new, generalisable knowledge |
| Typical design | Quality improvement, implementation, program evaluation | Original quantitative, qualitative, or mixed methods study |
| Setting | Clinical site or health system partner | Sites chosen for the research question |
| Result | Evidence of change and a plan to sustain it | Findings that add to the literature |
You will usually have a chair and two or more members, sometimes including a clinical partner or a methodologist. Choose them for their fit with your topic and their responsiveness, then agree on how often you will meet and how drafts will be reviewed. Approval typically runs in stages: proposal defense, ethics or IRB determination, data collection or implementation, final defense. A DNP project often receives a QI or non-research determination, while a dissertation study more often needs IRB review. Build those waiting periods into your schedule from the start.
Programs vary, but five chapters is common for both. What changes is what fills them.
The first three chapters form the proposal. If your program calls for a shorter capstone, compare with the capstone project guide and the research proposal guide.
Our nursing writers can support you with sections, editing, and formatting, following your committee's requirements.
The purpose statement is one or two sentences that tell the reader what you will do, in what setting, with whom, and how you will judge it. Use plain verbs (implement, evaluate, explore, examine) and avoid promising results.
| Version | Purpose statement |
|---|---|
| Weak | The purpose of this project is to look at improving patient education in hospitals. |
| Strong (DNP) | The purpose of this DNP project is to implement and evaluate a nurse-led teach-back protocol for discharge education on one fictional adult medical unit, measuring change in documented teach-back use and in patient-reported understanding over twelve weeks. |
| Strong (PhD) | The purpose of this qualitative descriptive study is to explore how newly licensed nurses in acute care describe the factors that shape their decision to stay in or leave their first position. |
Both strong versions name the design, population, setting, and focus, and neither claims an outcome in advance. The examples are fictional and for structure only.
Choose a framework that guides decisions rather than one that simply looks scholarly, and state how it shapes the intervention or the interview guide. In the methods chapter, be exact enough that another researcher could repeat the work. In the results chapter, keep description and interpretation apart: report the numbers or themes first, and save meaning for the discussion.
Programs, particularly DNP programs, expect you to share your work. Plan for a defense presentation, a poster (see the poster guide), an executive summary for your clinical partner, and possibly a manuscript or conference abstract. Cite carefully throughout; the dissertation citation guide shows how to reference other doctoral work.
Typical problems include a purpose that shifts between chapters, a framework that appears in Chapter 2 and then disappears, and a discussion that repeats the results instead of interpreting them. Another is working alone for months and then discovering the committee wants a different direction. Follow your institution's academic-integrity policy and program requirements, especially on the use of shared data and your own earlier coursework.
Some programs allow it, but many require practice-focused work. Ask your committee chair early.
It varies widely by institution and method, so rely on your program's manual and past approved examples.
If your analysis goes beyond basic descriptive statistics, consult one before finalizing your plan.
