Most evidence-based practice models assume a project team and an organizational sponsor. The Stetler Model starts somewhere else: one practitioner who notices a gap between practice and evidence.
That individual focus makes it a strong fit for capstones that begin with a single nurse's observation. This guide covers the model's history, what each of its five phases requires, a worked example, and the mistake that appears most often in student work: describing Stetler as if a team ran the project.
The Stetler Model at a Glance
The Stetler Model guides a practitioner through five phases: Preparation, Validation, Comparative Evaluation and Decision-Making, Translation and Application, and Evaluation.
Its distinctive features are a formal critique of each source, an explicit decision to use, consider use, delay use or not use the evidence, and a broad definition of evidence that includes quality data, expert opinion and patient preference alongside research.
Where the Model Came From
Cheryl Stetler and Gwen Marram published the first version in 1976. It helped individual nurses decide whether and how to apply research findings to their own practice, at a time when most attention went to organizational research utilization programs.
Stetler revised the model in 1994 and again in 2001. The 2001 version, the one usually cited today, reframed it as a model for evidence-based practice rather than research utilization alone.
That revision widened what counts as evidence. Quality improvement data, program evaluation, expert consultation, clinical experience and patient or family preference all sit alongside published research.
This matters for how you write about it. A capstone that combines unit data, input from a wound care specialist and several published studies is using the model exactly as intended, not a weaker version of it.
The Five Phases at a Glance
Each phase produces a decision or output that the next phase depends on. Phase 3 forces an explicit go or no-go choice before any implementation, a checkpoint several other models leave implied.
| Phase | What it requires | Typical output |
|---|---|---|
| 1. Preparation | Define the problem or purpose, note influencing factors such as time and resources, gather research and non-research evidence | A defined practice question and an initial evidence pool |
| 2. Validation | Critique each source for soundness, credibility and relevance; screen out what does not hold up | A validated subset of evidence |
| 3. Comparative Evaluation and Decision-Making | Synthesize the evidence, weigh fit, feasibility and current practice, then decide | Use, consider use, delay use or do not use |
| 4. Translation and Application | Choose the type and form of use, then build an action plan | A concrete practice or implementation plan |
| 5. Evaluation | Assess whether the change achieved its goal, informally, formally or both | Results that confirm, adjust or reverse the change |
Phase 1: Preparation
Name the specific practice concern and be honest about what shapes how far you can take it. Time, the visibility or sensitivity of the issue, and realistic effort all belong here.
Gather evidence broadly at this stage. Published research, existing quality data, professional guidelines and colleague consultation all count, so do not narrow too early to only what is easy to find.
Phase 2: Validation
Not everything from Phase 1 survives. Critique each study for method, how current it is and how well its sample matches your setting.
Screen guidelines and quality data too. Ask how directly they apply to your population and unit, not only whether they come from a credible body.
If the surviving evidence is too thin or too weak, say so here. You can seek more evidence or scale the project down, and that honesty is part of using the model properly.
Phase 3: Comparative Evaluation and Decision-Making
Synthesize what the validated evidence shows as a whole. Then test it against practical questions: does it fit your setting, is it feasible with your resources and risk level, and how does it relate to current practice?
The phase ends with one of four decisions. Stating which one your project reached, and why, separates real use of the model from a literature summary.
| Decision | Meaning |
|---|---|
| Use | Strong evidence that fits the setting well enough to apply now |
| Consider use | Promising evidence applied cautiously, for example as a small pilot |
| Delay use | More information, time or resources needed before deciding |
| Do not use | Evidence, fit or feasibility does not support moving forward now |
This is where Stetler departs most clearly from models such as Iowa. Fit and feasibility are weighed as separate questions, so excellent evidence can still lead to a delay decision if your setting cannot support it yet.
Phase 4: Translation and Application
Once you decide to use or consider use, define the kind of use you intend. The model names three types.
- Instrumental: a concrete change in action or procedure, such as a new step in a routine.
- Conceptual: a change in how you think about a problem, without an immediate procedural change.
- Symbolic: using evidence to justify or persuade others about a change.
Then decide whether application is formal, with a written plan, or informal, and whether the evidence is applied directly or adapted to your setting. Most capstones aim for formal, instrumental use, because faculty want a defined action to evaluate.
Phase 5: Evaluation
Compare the outcome with what you expected in Phase 3. The model accepts informal, self-monitored evaluation for an individual change as well as formal evaluation with defined measures and a comparison period.
Pick the level that matches your scope. DNP projects should lean toward the formal end: a stated metric, a measurement window and baseline compared with post-change data.
Either way, state what the results mean: continue, adjust, scale to a wider group or stop.
Worked Example: PRN Pain Reassessment Documentation
This example stays at individual-practitioner scale through all five phases. A day-shift medical-surgical nurse notices inconsistent documentation of pain reassessment after PRN opioid doses and decides what to do on her own initiative.
Preparation. Reviewing her own charting, she sees that reassessment after PRN opioids is sometimes recorded within 30 minutes and sometimes missed for hours. She limits the problem to her own practice and gathers hospital policy, a professional pain management standard and two recent quality improvement articles.
Validation. The hospital policy is current and directly applicable, and the professional standard is credible. One article comes from a comparable medical-surgical unit and holds up well. The other, from an ICU with continuous monitoring, is judged a poor fit and set aside.
Decision. The remaining evidence supports reassessment within a defined window after a PRN opioid dose, set by hospital policy, to catch oversedation and confirm pain relief. Her EHR already supports reminders and nothing new needs approval, so fit and feasibility are good. She decides to use the evidence in her own practice first.
Translation. This is formal, instrumental use: a personal checklist and a self-set EHR reminder, rather than an intention to try to remember. She plans a two-week personal trial before raising it with her charge nurse.
Evaluation. She tracks her reassessment timing for two weeks against the baseline from her chart review. Compliance improves, and she brings the result to her charge nurse as the basis for a unit pilot, at which point an organizational model such as Iowa or i-PARIHS would carry the wider rollout.
Nothing here needed a project charter, a multidisciplinary team or leadership sign-off. Forcing a team-based framing onto a project like this usually weakens the write-up.
When to Choose the Stetler Model
Choose Stetler when the real starting point is one practitioner's observation rather than a chartered organizational initiative. It suits a BSN or MSN student changing their own practice, a piece of workflow they control, or a pilot run before going to a committee.
It also suits a mixed evidence base, since the model treats research plus quality data, expert input and patient preference as intended use. If your rubric wants a visible appraisal step and a documented go or no-go decision, Phases 2 and 3 give you that structure.
If the project is a unit-wide or system-wide rollout with a team and sponsorship from day one, the Iowa Model or i-PARIHS will carry the organizational story more naturally. Some DNP projects use Stetler for the champion's initial decision, then name a switch to an organizational model as the project scales.
Stetler Compared with Other EBP Models
If faculty ask why you chose Stetler, the honest answer is usually that the real decision-maker was one practitioner, and the model needed to show that person's critique and decision.
| Model | How it differs from Stetler |
|---|---|
| Iowa Model | Starts from an organizational trigger and assumes a team carrying change to unit or system level |
| PARIHS and i-PARIHS | Gives structured attention to context, recipients and facilitation, which Stetler covers only lightly under fit and feasibility |
| ACE Star Model | Maps how evidence travels from primary research to practice rather than one person's decision to apply it |
| Johns Hopkins EBP Model | Uses a team-based practice question, evidence and translation process with detailed appraisal tools |
Where Stetler Fits in Your Capstone Document
Mapping phases to chapters shows faculty that the framework shapes the whole paper rather than sitting in one section.
| Capstone chapter | Stetler phase |
|---|---|
| Introduction and background | Preparation: the problem, its scope and influencing factors |
| Literature review | Validation: your critique of research and non-research evidence |
| Framework | The model explained, and why an individual-practitioner model fits |
| Methods: decision | Comparative Evaluation: your stated decision and its rationale |
| Methods: implementation | Translation and Application: type and form of use, action plan |
| Results and discussion | Evaluation: what the outcome data show and next steps |
Common Mistakes with the Stetler Model
These errors show up repeatedly in capstone drafts. Each one suggests the model was named rather than used.
- Describing a team or sponsor behind the project when the work was one practitioner's decision.
- Skipping the Phase 2 critique and never saying which sources were weak or a poor fit.
- Implying every source was a published study instead of naming quality data, consultation or patient preference.
- Never stating which of the four Phase 3 decisions the project reached.
- Blurring instrumental, conceptual and symbolic use, or skipping the distinction.
- Reporting Phase 5 as a closed success without saying whether to scale, adjust or reverse.
How NurseCapstone Helps with the Stetler Model
Send your practice concern, the evidence you have gathered and your rubric. A writer matched to your BSN, MSN or DNP level drafts a model framework section that works through each phase, names your evidence types and states the Phase 3 decision.
The section is written from scratch for your project and plagiarism-checked. Use it as a reference for your own writing, with free revisions within the scope of your original request.

Frequently Asked Questions
The Iowa Model starts from an organizational trigger and assumes a team carrying the change. Stetler was built for one practitioner deciding whether to apply evidence to their own practice or a small change they control.
Yes. The phases work for an individual or a small group; what changes is who decides in Phase 3. For a department-wide rollout with sponsorship from the start, an organizational model usually fits better.
Use, consider use, delay use and do not use. Your capstone should state which one the project reached and why.
Yes. Since the 2001 revision it explicitly includes quality data, program evaluation, expert consultation, clinical experience and patient preference alongside research.
Yes. It does not assume a team or formal authority, so a BSN student changing their own practice can work through all five phases honestly.
Instrumental use changes a concrete action, such as a new documentation step. Conceptual use changes how you think about a problem without an immediate procedural change.
The model allows informal self-monitoring, but DNP projects should use a defined metric, a measurement window and a baseline comparison.
Yes. Some projects use Stetler for the initial individual decision and an organizational model such as Iowa for a later unit rollout, naming the transition clearly.
