How to Critique a DNP Mixed Methods Project and Summarize Its Results
A section-by-section guide for DNP students on how to select the right project, critique quantitative and qualitative methods separately, summarize the findings with precision, and connect both strands of evidence to the practice-focused question — without losing analytical marks to vague summaries or disconnected critiques.
This assignment looks straightforward on the surface — pick a DNP project, critique the methods, summarize the results, link it to the practice-focused question. But most students lose marks in at least two of those four steps. Either the quantitative critique stays at the level of “data was collected and analyzed” without actually evaluating the method’s rigor, or the qualitative summary reproduces what the author said without assessing how well the method answered the question it was supposed to answer. And the connection to the practice-focused question? That section is where almost every student goes vague. This guide breaks each step down and tells you what a high-scoring paper actually does differently.
This is not a research summary or an abstract of the project you chose. It is a critique — meaning you are evaluating the quality, rigor, and appropriateness of the methods used, not just describing what the researchers did. There is a significant difference between saying “the researcher used surveys to collect data” and saying “the choice of a validated Likert-scale instrument was appropriate for measuring compassion fatigue severity, though the cross-sectional design limits causal inference.” The rubric specifically rewards metrics and data for quantitative critique, and specific examples for qualitative summary — which means vague description will cost you marks in both categories. Every claim in your critique needs to be grounded in what you actually read in the project, with enough specificity that a reader could locate the section you are evaluating.
What This Guide Covers
What This Assignment Actually Tests
The rubric has three graded content areas: the quantitative critique, the qualitative summary, and the connection between findings and the practice-focused question. Written expression and APA formatting are the remaining marks. What that structure tells you is that the assignment is testing whether you can read a complex scholarly project — one that uses two different methodological approaches simultaneously — and evaluate each approach on its own terms before synthesizing both into a practice argument.
Notice that the quantitative and qualitative sections carry equal marks. That matters. A lot of DNP students are more comfortable with quantitative language — statistics, sample sizes, p-values — and less practiced at evaluating qualitative rigor. But the rubric weights them identically. A paper that writes three strong pages about the quantitative component and half a page of vague notes about themes and lived experience will score significantly lower than one that gives genuine analytical attention to both.
The practice-focused question section carries half the marks of the other two — but it is not a throwaway. It is the integrative argument the whole paper has been building toward. If your critique and summary are strong but your connection to the practice question is weak, you are leaving about 17% of the total marks on the table.
How to Choose the Right DNP Project
The assignment gives you four options. Three are full dissertations — Frazier (2023), Karamichos (2023), and Rampersad (2023) — and one is an executive summary of a quality improvement initiative (Simons, 2023). That difference matters more than students realize when they are choosing.
Secondary Traumatic Stress in Emergency Room Nurses — Mixed Methods
This project examines the lived experience of secondary traumatic stress (STS) in ER nurses using a mixed methods design. The quantitative strand likely involves validated instruments measuring STS severity across a sample of nurses. The qualitative strand explores the subjective experience through in-depth interviews or similar methods. This project is a strong choice if you are comfortable with trauma-informed language and can discuss both statistical measures of STS and the phenomenological texture of nurses’ accounts. The practice-focused question centers on understanding what STS looks like from both a measurable and an experiential standpoint — and what that means for clinical environments and leadership practice.
Professional Identity of the Nurse Practitioner — Mixed Methods
This project investigates how nurse practitioners understand and construct their professional identity, using a mixed methods approach. The quantitative strand might use surveys to measure identity dimensions across a sample of NPs. The qualitative strand probably explores how NPs narrate and describe their professional role. This is the right choice if your background or interest is in advanced practice nursing and role development. The practice-focused question has direct implications for NP education, scope of practice policy, and how graduate programs shape professional formation — giving you rich material for the linking section of your paper.
Oncology Nurses, Compassion Fatigue and General Health — Mixed Methods
This Walden University dissertation examines the relationship between compassion fatigue and general health outcomes in oncology nurses, using a mixed methods design. It is publicly available through Walden’s ScholarWorks repository, which makes it easier to access the full text and read the actual data sections — a practical advantage when you need to cite specific metrics and findings. The practice-focused question addresses a pressing workforce issue in oncology nursing. If you choose this one, make sure you engage with the actual instruments used (likely the ProQOL scale), the statistical outputs, and the thematic findings from the qualitative strand — not just the introduction and conclusion.
QI Initiative: Reducing Orthopedic Surgical Site Infections — Executive Summary
This is the odd one out. It is an executive summary of a quality improvement initiative, not a full dissertation. The format is shorter and more applied. If your assignment is asking you to critique “quantitative and qualitative methods” in depth, this project may give you less material to work with — executive summaries compress methodology by design. Choose this only if your instructor has confirmed it is suitable for the depth of critique the rubric requires. For a 5–7 page paper that needs metrics and data in the quantitative section and specific examples in the qualitative section, the full dissertations give you more to work with.
The Practical Decision Rule
Pick the project whose topic area you understand best clinically and whose full text you can actually access. You cannot critique what you have not read. Rampersad (2023) is available freely via Walden’s repository. Frazier and Karamichos are available through ProQuest — check whether your institution provides access. If you cannot get the full text, you cannot do the quantitative critique section properly, because that section requires specific metrics, sample sizes, instruments, statistical tests, and results. Picking a project you can access in full is a prerequisite for a strong paper.
Understanding Mixed Methods in DNP Projects
Mixed methods is not just “quantitative plus qualitative.” It is a specific research design philosophy that combines both approaches within a single study to answer a question that neither method could fully address alone. Understanding what kind of mixed methods design the project used — and why — is foundational to your critique, because you cannot evaluate whether the design was appropriate without knowing what it was trying to do.
Convergent (Parallel) Design
Both quantitative and qualitative data are collected at roughly the same time, analyzed separately, and then merged or compared. The logic is that the two strands should converge on — and ideally confirm — a shared finding. In your critique, assess whether the two strands were genuinely independent and whether the convergence (or divergence) was meaningfully discussed by the author.
Explanatory Sequential Design
Quantitative data is collected first and analyzed. The qualitative phase then explains or elaborates the quantitative results. The logic is that numbers tell you what is happening; qualitative data tells you why. In your critique, look at whether the qualitative questions were genuinely driven by the quantitative findings, or whether the two strands operated independently despite the sequential label.
Exploratory Sequential Design
Qualitative data is collected first to explore a phenomenon, then quantitative methods are used to measure or test what was found qualitatively. Common when a validated instrument does not yet exist for the construct being studied. In your critique, evaluate whether the qualitative findings actually shaped the quantitative component, or whether the connection was superficial.
For any of the four project options, your first analytical task is to identify which type of mixed methods design was used and whether that design was appropriate for the practice-focused question. A project studying the lived experience of secondary traumatic stress (Frazier, 2023) needs a design that gives the qualitative strand enough depth to capture that experience — not just a design that tags brief interviews onto a survey study and calls it mixed methods.
The authoritative framework for evaluating mixed methods quality in health research is: Creswell, J. W., & Plano Clark, V. L. (2018). Designing and conducting mixed methods research (3rd ed.). SAGE Publications. This text provides the specific criteria for design appropriateness, integration quality, and rigor in mixed methods studies that your critique should reference. For DNP-specific application, the American Association of Colleges of Nursing (AACN) DNP Essentials document establishes practice scholarship standards that contextualize what DNP projects are designed to accomplish: AACN.

Identifying the Practice-Focused Question Before You Write Anything
Before you critique a single method, you need to identify and state the practice-focused question the project was designed to answer. This is not the same as the research questions listed in the methodology section, though those are related. The practice-focused question is the overarching clinical or organizational problem the DNP project addresses — the gap in practice that motivated the entire study.
In Rampersad (2023), for example, the practice-focused question is not simply “does compassion fatigue affect oncology nurses?” It is closer to: what is the relationship between compassion fatigue and general health in oncology nurses, and what does understanding that relationship mean for nursing leadership and workforce retention practice? That framing — which links an empirical question to a practice implication — is what a DNP practice-focused question looks like. It is always pointing from evidence toward action.
Locate the practice-focused question in the project’s introduction or purpose statement. Write it down before you start drafting. Every section of your paper — including your method critiques — should be written with that question in view, because the whole point of the critique is to evaluate whether the methods were adequate to answer it.
How to Critique the Quantitative Methods — What the Rubric Is Actually Looking For
The rubric says “excellent” means you “comprehensively and clearly describe the patient care delivery gap or problem” and include “metrics and data for support.” That language might seem like it belongs in a different assignment — but it makes sense when you realize the rubric is evaluating whether your critique demonstrates that you read and understood the actual quantitative results, not just the methodology section. A quantitative critique without metrics is a methodology description, not a critique.
Weak Quantitative Critique
“The researcher used a survey to collect data from nurses. Statistical analysis was performed. The results showed that compassion fatigue was present among the nurses in the sample. This supports the idea that compassion fatigue is a problem in oncology nursing.”
No instrument named. No sample size. No statistics reported. No design evaluation. No limitations. This describes without critiquing and earns marks only in the “fair” or “poor” range.
Strong Quantitative Critique
“Rampersad (2023) used the Professional Quality of Life Scale (ProQOL-5), a validated 30-item instrument with established reliability in nursing populations (Stamm, 2010). The sample of [n] oncology nurses was recruited via [method], with a response rate of [x]%. Descriptive statistics indicated [specific finding], and correlational analysis revealed [statistic] between compassion fatigue subscales and general health scores (r = [value], p = [value]). While the ProQOL-5’s validity strengthens the quantitative strand, the cross-sectional design limits causal interpretation — a relevant constraint given the practice-focused question requires understanding whether intervention can alter fatigue trajectories over time.”
How to Summarize the Qualitative Methods — What Distinguishes Good from Generic
The rubric says the qualitative summary should “describe the gap or problem by addressing the type of indicators” and include “relevant, specific, and appropriate examples that fully support the identification.” That tells you two things. First, the qualitative methods section is not just a description of what themes were found — it is also an evaluation of whether the method used was adequate to surface those indicators. Second, specific examples from the qualitative findings need to appear in your summary.
What to Evaluate in the Qualitative Strand
- The qualitative design: Was it phenomenology, grounded theory, case study, content analysis, or thematic analysis? Each of these is suited to different questions. Phenomenology fits “lived experience” questions (like Frazier’s STS study). Grounded theory fits questions about how processes develop over time. Mismatching design to question is a methodological flaw worth naming.
- The sampling approach: Qualitative studies use purposive or purposeful sampling, not random sampling. Was the sampling strategy appropriate? Was saturation reached and reported? How many participants were interviewed, for how long, and through what method (face-to-face, telephone, focus group)?
- Data collection method: Were semi-structured interviews used? What were the guiding questions? How were responses recorded and transcribed? Was member checking or peer debriefing used to strengthen credibility?
- Analysis approach: How were themes generated — deductively, inductively? What software was used, if any? Were themes clearly defined and illustrated with participant quotes?
What to Include From the Qualitative Findings
- The themes: Name each major theme and sub-theme that emerged. Do not just say “several themes emerged.” Name them, describe them, and explain what they reveal about the practice problem.
- Specific examples: The rubric explicitly requires “specific examples.” That means participant quotes, illustrative cases, or concrete descriptions of what the thematic findings showed — not just the theme label. If a theme was “emotional isolation,” your summary should include what that looked like in participants’ accounts.
- Credibility and trustworthiness: Evaluate whether the author established credibility (equivalent to validity in qualitative terms) through strategies like triangulation, member checking, reflexivity statements, or thick description. These are the qualitative equivalents of the reliability statistics you report in the quantitative section.
- Limitations: Qualitative findings are not generalizable in the statistical sense — they are transferable. Was the context described with enough richness to allow readers to assess transferability to their own settings?
The Analytical Move That Earns Marks in the Qualitative Section
For every theme you describe, push to the practice implication. A theme labeled “emotional exhaustion from patient deaths” (hypothetical, for illustration) should not sit alone as a description. Your summary should evaluate what that theme means for the practice-focused question. If the practice question is about whether compassion fatigue affects oncology nurses’ general health, and a qualitative theme reveals that nurses describe physically somatic symptoms — sleep disruption, appetite loss, chronic headaches — as directly linked to their emotional burden, that is evidence connecting the qualitative strand to the health outcomes the quantitative strand measured. That connection is what “linking to the practice-focused question” actually looks like in practice.
Linking Both Strands of Findings to the Practice-Focused Question
This section is where the mixed methods logic of the whole paper has to pay off. You have evaluated the quantitative component and summarized the qualitative component. Now you have to show how those two bodies of evidence — together — answer the practice-focused question. The word “together” is doing real work here. A linking section that discusses the quantitative findings and then the qualitative findings in separate paragraphs without integrating them is not a linking section. It is two summaries stapled together.
| Project | Practice-Focused Question (Approximate) | How Both Strands Answer It |
|---|---|---|
| Frazier (2023) | What is the lived experience of secondary traumatic stress in ER nurses, and what does it mean for practice? | Quantitative strand establishes prevalence and severity of STS using validated measures. Qualitative strand describes what STS feels like from the inside — the coping failures, the professional withdrawal, the emotional numbing. Together they establish both the scale of the problem and its human texture, giving nurse leaders evidence for both surveillance systems and supportive interventions. |
| Karamichos (2023) | How do nurse practitioners understand their professional identity, and what are the practice implications? | Quantitative strand measures identity dimensions across a sample of NPs using survey data. Qualitative strand reveals how NPs narrate their professional role — the tensions, the pride, the ambiguity. Together they show both how identity is distributed across a population and how it is constructed in individual practice — informing NP education and scope of practice advocacy. |
| Rampersad (2023) | What is the relationship between compassion fatigue and general health in oncology nurses? | Quantitative strand provides correlational evidence linking ProQOL subscale scores to general health measures. Qualitative strand describes the mechanisms — how nurses experience the fatigue in their bodies, their relationships, and their clinical judgment. Together they establish both that the relationship exists (quantitative) and how it operates in lived practice (qualitative). |
| Simons (2023) | Can nasal decolonization reduce orthopedic surgical site infections in a QI context? | Quantitative strand reports infection rate data before and after the intervention. Qualitative strand (if present) may capture staff and patient experience of the protocol. Together they establish both effectiveness and implementation feasibility — the two questions any QI practice question ultimately needs to answer. |
The linking section of your paper needs to make the integration argument explicitly. Start by restating the practice-focused question. Then show how the quantitative findings partially answer it — what they establish, and where they leave off. Then show how the qualitative findings take over where the quantitative stopped. Then make the combined argument: given both strands of evidence, what is the answer to the practice-focused question, and what are the implications for practice change, policy, or nursing leadership?
How to Structure the Full Paper
-
Introduction — State the Project and Purpose (half page)
Name the project you selected, the author, and the year. State the practice-focused question. Briefly explain why this project uses a mixed methods approach and what the paper will cover. Do not begin your critique here — this section sets up the analysis to follow. Your purpose statement should clearly delineate that the paper will critique quantitative methods, summarize qualitative methods, and link findings to the practice-focused question — using the rubric’s language is not cheating, it is strategic.
-
Quantitative Methods Critique (1.5–2 pages)
Cover the five elements outlined above: design, instrument, sample, statistical analysis, and limitations. Report specific metrics and statistics from the project’s results section. Evaluate whether each element was appropriate for answering the practice-focused question. Do not just describe — evaluate. For every element, ask: was this rigorous, and was it fit for purpose?
-
Qualitative Methods Summary (1.5–2 pages)
Cover the design, sampling, data collection, analysis, and trustworthiness. Name and describe the themes. Include specific examples from the findings — participant quotes or detailed theme descriptions. Evaluate credibility and transferability. Connect each major theme to the practice-focused question so this section is doing double duty: summarizing the qualitative findings and beginning to build the practice argument.
-
Integration: Linking Both Strands to the Practice-Focused Question (1–1.5 pages)
This is not a summary of what you have already said. It is a synthesis argument. Use the quantitative and qualitative findings together to answer the practice-focused question. Identify points of convergence — where both strands point to the same conclusion. If there are points of divergence — where the quantitative data and qualitative accounts are in tension — name that tension and explain what it means for practice. Divergence in mixed methods is not a flaw; it is often the most analytically interesting finding.
-
Conclusion (half page)
Summarize the key contribution of the project to the practice-focused question. State what the evidence — in combination — supports in terms of practice change, policy recommendation, or clinical leadership action. Do not introduce new critique material here. The conclusion should feel like the answer to the question the introduction asked.
Where Most DNP Students Lose Points in This Assignment
Describing Methods Without Evaluating Them
“The researcher used semi-structured interviews with ten nurses. The data was transcribed and analyzed using thematic analysis. Three themes emerged from the data.” This describes the qualitative process but evaluates nothing. Was ten participants enough for saturation? Was thematic analysis the right approach for this question? Was credibility established? None of this is addressed, so no analytical marks are earned.
Instead
Evaluate each methodological choice: “Semi-structured interviews with ten participants is within the typical range for phenomenological inquiry (Creswell & Poth, 2018), and the author reports that data saturation was reached by the eighth interview — a credibility-strengthening disclosure. Thematic analysis is appropriate for the descriptive phenomenological orientation of this project, though the author does not report member checking or an audit trail, which weakens the trustworthiness argument.”
Quantitative Section With No Statistics
“The quantitative results showed that many nurses experienced high levels of compassion fatigue. The data indicated a relationship between compassion fatigue and health outcomes.” No instrument named. No sample size. No statistical test named. No p-values or effect sizes reported. No rubric marks for “metrics and data” are earned by this paragraph.
Instead
Go into the results section of the project you chose and pull actual numbers. Name the instrument. Report the sample size. Identify the statistical test used. Include at least the key statistics — correlation coefficients, regression beta values, mean comparison results — and evaluate what they show. If you cannot find these in the project, you need to read the methodology and results chapters more carefully before writing.
Linking Section That Separates Rather Than Integrates
“The quantitative findings showed that compassion fatigue was significantly related to health outcomes. The qualitative findings showed that nurses felt emotionally drained and isolated. These findings are relevant to the practice-focused question.” This summarizes both strands again but does not actually argue how they converge, what they mean in combination, or what the answer to the practice question is. The word “relevant” does no analytical work.
Instead
Make the integration argument explicitly: “The quantitative strand establishes that compassion fatigue scores correlate significantly with decreased general health — providing the population-level evidence that the problem is measurable and widespread. The qualitative strand explains the mechanism: nurses describe a withdrawal from clinical engagement, disrupted sleep, and emotional numbing that mirrors the somatic and psychological decline the ProQOL scores captured statistically. Together, these strands answer the practice-focused question not just by confirming that a relationship exists, but by mapping how it operates — which is exactly the information a nurse leader needs to design an intervention.”
Choosing a Project You Cannot Access in Full
Students sometimes choose Frazier or Karamichos, discover they cannot access the full ProQuest dissertation without an institutional login, and end up critiquing based on the abstract alone. An abstract gives you the practice question and the headline findings — it does not give you the sample size, the instrument reliability statistics, the specific themes, or the qualitative participant quotes the rubric requires. If you cannot access the full text, choose Rampersad (2023) through Walden’s open repository instead.
Instead
Before committing to a project, verify you can access the full dissertation text — methodology, results, and discussion chapters. If your institution provides ProQuest access, use it. If not, Walden ScholarWorks is free and provides Rampersad (2023) in full. The specificity the rubric requires — metrics, statistics, specific qualitative examples — is only available in the full text. Plan accordingly before you start writing.
- The practice-focused question is clearly identified and stated in the introduction — not confused with the research questions in the methodology section
- The quantitative critique names the specific instrument used and evaluates its validity and reliability with evidence from the project
- The quantitative critique reports specific metrics — sample size, response rate, statistical tests, p-values or effect sizes — not just general descriptions of what was done
- The quantitative critique evaluates design appropriateness for the practice-focused question, not just describes the design
- The qualitative summary names the specific design (phenomenology, thematic analysis, etc.) and evaluates its fit to the research question
- The qualitative summary includes at least two or three specific examples from the findings — named themes described in detail, or participant quotes where available
- The qualitative summary evaluates trustworthiness — credibility, transferability, confirmability — not just describes the analysis process
- The linking section integrates both strands rather than summarizing them separately — convergence or divergence between the two strands is explicitly addressed
- The linking section ends with a clear practice implication drawn from the combined evidence — what should change in practice as a result of what both strands found
- The paper is 5–7 pages plus title and reference pages — within the prescribed length, which requires tight writing without padding
- APA format is consistent throughout — in-text citations, reference list, headings, page numbers, running head if required
- At least three references from the required readings are cited — Bangura (2024), Khoja & Moosa (2023), and/or Tzeng & Yin (2017) — in addition to the project being critiqued
Sources That Strengthen This Paper
Sources That Belong in This Paper
- The DNP project itself — this is your primary source. Cite it correctly using the ProQuest dissertation format or the repository format as applicable. Every claim about the methods and findings should be traceable to a specific section of the project, ideally with page numbers.
- Required readings from the assignment: Bangura (2024), Khoja & Moosa (2023), and Tzeng & Yin (2017) are listed as required. They address falls prevention and intentional rounding — which may not directly match your chosen project’s topic, but they can be used to discuss evidence-based practice standards, QI methodology, or the broader literature on nursing workforce issues. Work them in meaningfully — citing them just to hit the source count is detectable and earns no credit.
- Creswell & Plano Clark (2018) — the authoritative text on mixed methods design. Cite it when evaluating whether the design type was appropriate and whether integration was handled correctly.
- AACN DNP Essentials (2021) — establishes what DNP scholarship is for. Cite it when framing the practice-focused question and discussing practice implications in the linking section.
- The instrument’s original validation study — if the project used the ProQOL, the Secondary Traumatic Stress Scale, or another validated tool, citing the instrument’s validation literature strengthens your quantitative critique significantly.
Sources That Weaken This Paper
- Websites, nursing blogs, or general health information sites — not peer-reviewed and not appropriate for doctoral-level citation
- Textbook summaries of mixed methods without engaging with Creswell or other primary methodology texts — signals you are not citing from depth
- Citing only the project’s abstract — the rubric requires metrics, statistics, and specific examples that are only in the full text. Abstract-level citations produce abstract-level critique
- Undated sources or sources with no identifiable author — not APA-citable and not credible in a doctoral paper
- Over-relying on the required readings at the expense of the project itself — the required readings are context; the project is the primary object of analysis. Reverse that ratio and the paper loses focus
