To compare nursing theorists in an essay, use the same analytical questions for each theory and explain how their differences influence nursing decisions. A strong comparison goes beyond two biographies or a table of definitions. It develops a reasoned judgement about what each perspective reveals, what it leaves uncertain and where it may be useful.
This guide focuses on comparing nursing models and theories, including assignments organised around person, health, environment and nursing. It also explains how to avoid confusing nursing theories with general psychological theories. Your assessment brief determines which theorists, concepts and sources you should use.
Read the task before choosing your comparison
Underline the instruction words. An essay asking you to compare two theorists needs explicit similarities and differences. A task asking you to apply a theory needs a defensible connection to the case. A critical evaluation requires a judgement supported by evidence and criteria. These tasks can overlap, but they are not interchangeable.
Next, identify whether the assignment supplies the theorists or allows a choice. If it names two models, do not replace one because another is easier to explain. If you can choose, select perspectives with a meaningful comparison. Two approaches that differ in their central purpose can produce a useful argument, provided you acknowledge that they were developed to answer different questions.
Write a one-sentence planning statement: “This essay compares how the selected perspectives explain the nursing role in relation to the person and their context.” Then refine it around the actual brief. That statement helps you decide which historical details are relevant and which would become background without analytical value.
Distinguish a theory, a model and a framework carefully
Authors do not always use these terms in the same way. Rather than announcing a universal hierarchy, state how your chosen sources describe the work you are examining. A conceptual model may organise broad ideas about nursing, while a more focused theory may describe particular relationships. Your analysis should respect the scope claimed by the author.
Check whether you are comparing the original formulation, a later revision or a contemporary application. A later article might adapt a theory for a particular setting. That adaptation can be useful evidence, but it should not silently replace the original ideas. Record the version and publication details in your source notes.
University nursing libraries can help locate original works. Chamberlain University provides an original theory sources guide, and the University of Wisconsin–Milwaukee lists major nursing theory texts. Use such guides to find appropriate material, then cite the actual work you have read rather than attributing detailed theoretical claims to a catalogue entry.
Use shared criteria to compare nursing theorists
Choose a small set of criteria before drafting. The familiar concepts of person, health, environment and nursing can organise the comparison when they suit your brief. However, do not force every theorist into identical definitions. The way an author connects these concepts may matter more than whether each appears under a separate heading.
| Criterion | Questions to ask of both perspectives | Analytical purpose |
|---|---|---|
| Person | Who is the focus, and how are agency, needs and relationships understood? | Identify whose priorities shape the account. |
| Health | What counts as a desirable change or outcome? | Compare the goals implied by each approach. |
| Environment | Which social, material or interpersonal conditions receive attention? | Examine context and possible omissions. |
| Nursing | What does the nurse assess, contribute and evaluate? | Connect abstract ideas to professional action. |
| Use and limits | What evidence supports the application, and where does it fit poorly? | Develop a qualified judgement. |
The table is a planning aid, not a substitute for the essay. After completing it, look across each row. Ask whether an apparent difference changes the nurse’s interpretation of the situation. If it does not, explain why it is a minor distinction rather than presenting every difference as equally important.
Define the concepts using traceable sources
Begin with the module reading list and original theoretical writing where available. Add scholarly sources that explain or examine the theory. Keep separate notes for the author’s definition, your paraphrase and the application you are proposing. This prevents your own inference from being presented as the theorist’s claim.
A useful source note includes the concept, an accurate paraphrase, the page or section, the version of the theory and a short explanation of relevance. Avoid copying long definitions into the draft. The reader needs enough explanation to understand the comparison, followed by your analysis of its significance.
Older foundational sources may be necessary. A recent publication date does not automatically make a secondary summary more appropriate than the original text. At the same time, contemporary evidence can help evaluate how a theory has been interpreted in current practice. Use each source for the question it can answer.
Organise the essay around comparisons
A point-by-point structure often makes the argument easier to follow. For example, one section can compare the concept of the person, another the nursing relationship, and another the implications for the selected case. Within each section, explain both perspectives before reaching a judgement about that criterion.
A block structure can also work: explain the first theory, explain the second, then compare them. Its main risk is repetition. If most of the word count is spent on separate descriptions, the comparison may appear only in the conclusion. Use explicit cross-references and reserve sufficient space for evaluation.
Whatever structure you choose, make the thesis of the essay clear early. You might argue that the theories emphasise different dimensions of the same care problem, or that one provides a better fit for a particular task. Avoid deciding that one is universally superior before examining the evidence and the setting.
Worked example: compare what two perspectives make visible
The following is a fictional planning example, not a patient account or a clinical recommendation. Imagine an assignment about a person learning to manage a long-term condition who also feels uncertain about asking professionals for help. The task is to compare two theoretical perspectives, not to prescribe treatment.
One analytical route might examine self-care capability and the support needed to undertake particular activities. Another might examine the therapeutic relationship and how communication enables the person to participate. If you select Orem and Peplau for this comparison, verify their concepts against the texts required by your programme.
The analytical value lies in the different questions. What can the person currently do? What support do they want? How are concerns understood? What assumptions is the nurse making about independence or trust? The essay should show which questions arise from each perspective and how they affect interpretation of the same situation.
A weak paragraph would state that both theories help nurses provide holistic care. A stronger paragraph identifies the dimensions of care being emphasised, applies them to the scenario and explains a limitation. For example, a capability-focused interpretation could need additional attention to relationships; a relationship-focused interpretation could need more explicit detail about practical tasks.
These are proposed analytical questions, not claims that either theory necessarily ignores the other dimension. Check the original sources before attributing an omission. A fair comparison distinguishes between an actual limitation in the theory and a limitation in the way a student has chosen to apply it.
Evaluate application without claiming the theory proves effectiveness
A theory can provide a useful way to organise assessment or reasoning. That does not, by itself, demonstrate that an intervention based on it improves outcomes. When an essay makes an effectiveness claim, examine the study design, setting, comparison and outcomes rather than relying on the theoretical label.
Separate three questions: Is the interpretation faithful to the theory? Does the approach fit this situation? What evidence supports its effect? A paper describing a theory-based educational activity may answer the first two questions better than the third. Be precise about what the source establishes.
Also consider feasibility. An approach that assumes continuity of relationships may be harder to use during brief encounters. A model that requires detailed assessment may depend on information unavailable in the supplied scenario. Explain these constraints without assuming that practical difficulty automatically invalidates the theory.
Examine assumptions about independence and context
Terms such as independence, participation and wellbeing can hide different assumptions. Independence might mean completing a task without help, making one’s own decisions, or directing support from others. Define the meaning you are using and examine whether it reflects the person’s stated priorities.
Consider whether family, community, material resources and service access appear in your comparison. If a person cannot follow an agreed plan because transport is unavailable, an account focused only on motivation would be incomplete. The essay can use this example to test the explanatory reach of the chosen perspectives.
Do not portray culture as a fixed list of beliefs that determines behaviour. Explain which contextual information is actually supplied and where uncertainty remains. A sound theoretical application allows the person’s account to challenge the nurse’s first interpretation rather than treating the model as an answer already known.
Write paragraphs that reach a judgement
Start with a comparative claim rather than a generic topic sentence. Explain the relevant concept in the first perspective, then bring in the second using the same criterion. Apply the contrast to the task and end with a judgement that follows from the evidence. This makes the analytical movement visible.
For example, the paragraph could compare how each perspective understands participation. Its closing sentence should explain what that comparison means for the assignment’s case or argument. It should not simply repeat that both approaches are important. Use cautious language where the evidence supports a possibility rather than a conclusion.
Transitions should name the relationship: “Both approaches recognise…”, “The difference becomes relevant when…” or “This interpretation is limited because…”. Vary the wording naturally. A sequence of paragraphs beginning with “Furthermore” will not create coherence if the underlying comparison changes criteria without explanation.
Common mistakes when comparing nursing models
- Writing two biographies: retain only historical context needed to understand the ideas.
- Using different criteria: compare like with like before evaluating differences.
- Calling every theory holistic: explain the particular dimensions addressed.
- Forcing a perfect fit: discuss where the theory does not fully explain the scenario.
- Confusing interpretation with evidence: distinguish your application from a tested outcome.
- Using a theory name as a citation: cite a source that supports the specific concept.
Another frequent problem is replacing critical analysis with criticism. Identifying strengths and limits is useful only when the criteria are clear. A theory developed for one purpose should not be dismissed because it does not solve every organisational or clinical problem.
Check whether the comparison is fair
Test your draft for an unequal level of explanation. If one theory receives detailed discussion from an original text while the other is represented by a short online summary, the apparent difference may reflect your sources. Improve the evidence base before concluding that one perspective is less developed or less useful.
Also check whether your criteria favour the theory you preferred at the outset. A framework chosen because it provides detailed procedural guidance may look stronger if the only criterion is procedural detail. Explain why the criteria matter for the assignment and consider a criterion that exposes the preferred approach’s limitations.
Keep terminology consistent without erasing differences. Two authors may use similar words for different ideas or different words for related ideas. Define the terms in context and explain the relationship. Do not silently translate one theory into another’s vocabulary and then conclude that they say the same thing.
Prepare a defensible concluding judgement
Return to the essay’s purpose when weighing the comparison. The conclusion should say what the examination of shared criteria has established. It may identify complementary insights, a better fit for the particular case or a tension that neither perspective fully resolves. Tie the judgement to the analysis already presented.
Consider the strength of each part of the conclusion. A claim about conceptual fit may be well supported even when evidence about outcomes is limited. State those two positions separately. This allows you to make a clear argument without pretending that all questions have been answered equally well.
Finally, check that the conclusion could not be attached unchanged to an essay comparing any two theorists. It should name the particular relationship your analysis uncovered and explain its significance for the nursing question. Specificity is what turns a generic ending into an academic judgement.
Final nursing theory essay checklist
Check that the introduction identifies the theorists, the comparison criteria and the central argument. Each major section should address the same question for both perspectives. The application should use only information available in the scenario, with fictional illustrations clearly labelled.
Next, audit every conceptual claim against its source. Verify names, versions and quotations. Check that the conclusion weighs the comparison rather than introducing a new theory. If you include a comparison table, refer to it in the text and explain the most important implications.
Finally, compare the draft with the marking criteria. If analysis has the greatest weighting, reduce unnecessary description and use the space to justify your judgement. The aim is a coherent account of why the selected perspectives matter for this specific nursing question.
Use a final comparison test
Write the main judgement without looking at the draft. Then check whether the sections provide the evidence needed to support that judgement. If the conclusion depends on an idea that appears only in the final paragraph, develop it earlier or qualify it. This simple check helps distinguish an argument built through the essay from an opinion added at the end.
Compare the space given to each criterion as well as each theorist. Equal word counts are not always necessary, but the reader needs enough explanation to understand the relationship. A theory should not seem weaker simply because its concepts have been defined less carefully.
Frequently asked questions
Must I use person, health, environment and nursing?
Use them if the brief requires them or if they provide a meaningful comparison. Some tasks specify other criteria. Explain your framework and avoid assuming every theory organises these concepts identically.
Can I compare a nursing theory with a psychological theory?
Only when the assignment permits that comparison. Explain the different purposes and scope of the perspectives rather than treating them as interchangeable nursing models.
Are older references acceptable?
Foundational theoretical works may be essential. Combine them with suitable contemporary analysis where needed, and follow any source-date requirements in the brief.
Should I decide which theory is best?
Make a judgement proportionate to the question. You can identify a better fit for a particular purpose without claiming that one theory is best for every person or setting.
Get feedback on your comparison
For related guidance, read applying Nightingale’s environmental theory and using psychological theories in nursing assignments. These have different purposes from a comparison of nursing theorists.
If you need feedback on your own draft, send the brief, marking criteria and selected sources through our contact page. A review can identify uneven comparison, unsupported concepts and missing links between theory and application. You remain responsible for the submitted argument and your programme’s academic integrity rules.
