Development articles, not applications
The selection criterion is the whole assignment and it is stated in one clause: an article in which the development of a middle range theory is the major focus. Most articles a search on these terms returns are applications, not developments. They take an existing middle range theory and use it as a framework for a study, and describing one of those means writing about how a theory was used rather than how it was built, which is a different question and the commonest way this post loses marks. Development articles announce themselves in the title and abstract with words like derivation, synthesis, construction, refinement or a stated purpose of developing a theory of some phenomenon. Screen for that before you read anything in full, and be willing to reject a genuinely interesting article that turns out to apply a theory rather than develop one, because the prompt is asking about method.
Middle range is the second qualifier and it is worth checking rather than assuming. Grand theories describe nursing at the level of the discipline and are too abstract to be tested directly. Practice level theories are narrow enough to describe a single intervention in a single setting. Middle range theories sit between: they have a limited number of concepts, a defined scope, and enough concreteness to generate testable propositions, which is exactly why they matter in doctoral work. Uncertainty in illness, unpleasant symptoms, self-transcendence, comfort, transitions and chronic sorrow are the familiar examples. If the article you found describes something that applies to all of nursing or to one nursing unit's protocol, it is probably not middle range, and saying so briefly in your post demonstrates that you can place a theory on that continuum rather than accept its own label. That placement is also the fastest way to check whether the article is answering the question the prompt asked.
Describing how the theory was developed means naming the approach, and there are a small number of recognised ones. Deductive derivation takes a theory from another discipline and reformulates its concepts for nursing. Inductive development builds from qualitative data, typically grounded theory work with patients, so the concepts are named from what participants described. Synthesis combines findings from a body of existing research into a new formulation. Some theories are derived from a grand theory by narrowing its concepts to a specific phenomenon. Combined approaches are common. Name the one your article used, then show it: say what the starting material was, how concepts were identified and defined, how relational statements between them were formed, and what the authors did to establish that the result held together. Combined approaches are worth naming as combined rather than forced into one category. What you are demonstrating is that you can read a methods section as method.
The part most posts skip is what came after the theory existed. Development is not finished when concepts are named, and a strong article will describe some validation step, whether that is expert review, testing propositions against existing data, developing an instrument to measure a concept, or a subsequent study. Say what your article reports on this, and say plainly if it reports nothing, because an honest observation that the theory has not yet been tested is a legitimate finding at doctoral level and shows you are reading critically rather than summarising. This is also where the article's own limitations section usually earns its keep, and where you can offer a judgement rather than a report. A theory that has been formulated and then left untested is not a failed theory, but it is an incomplete one, and saying so is the judgement the prompt is inviting rather than a criticism of the authors. Doctoral reading is expected to reach that far.
The citation itself carries marks that are easy to lose. The prompt says share the article citation, and at DNP level that means a complete, correctly formatted APA reference, not a title and a year. Give the full reference and confirm the article is peer-reviewed rather than an editorial, a dissertation abstract or a textbook chapter reproduced in the database. It is also worth stating your search explicitly: the terms as the prompt specified them, any limiters you applied for date or peer review, how many results returned and how you narrowed them. That is two or three sentences and it makes the search reproducible, which is a habit the course is trying to build and which distinguishes a doctoral post from a masters level one. A search that cannot be repeated is not really evidence of a search, and this course grades the habit as well as the result. Two or three sentences carry it.
On execution, keep the post tight and ordered: search, selection and why it qualifies, the citation, the development account, then a short critical judgement. Length is not the point here and a long post that summarises the whole article has answered a question nobody asked. Where you make a claim about what middle range theory is or about a development method, cite the methodological source rather than relying on the article's own framing, since part of what is being assessed is whether you can locate the article's method within a wider vocabulary. Finally, resist the pull toward the most famous theories, since a thread in which everyone describes the same three will make your post harder to distinguish and will make the peer discussion narrower than it needs to be. A less familiar theory produces a more interesting post, and the search will surface several past the first page.

Screening CINAHL for theory construction
Recommended databases
- CINAHL
- PubMed
- Nursology
- Course text on theory development
Search sequence
- 1.Run the three specified terms in CINAHL and record the result count before applying limiters.
- 2.Limit to peer-reviewed and scan titles for derivation, synthesis, construction or development.
- 3.Read abstracts to confirm development rather than application is the stated purpose.
- 4.Check the theory's scope against a definition of middle range before committing to the article.
- 5.Look up the named development method in a theory text so you can describe it in its own terms.
Reference shortlist
These are authoritative starting points, not a ready-made bibliography. A qualified reviewer must confirm that each source fits the assignment and supports the claim beside which it is cited.

Review before submission
Common mistakes
- Choosing an article that applies a middle range theory as a study framework.
- Accepting an article's claim that its theory is middle range without checking scope.
- Summarising the article's findings instead of describing its development method.
- Naming an approach such as synthesis without showing what was synthesised.
- Ignoring what happened after the theory was formulated.
- Giving a partial citation rather than a complete APA reference.
- Selecting one of the same few famous theories the whole thread will use.
Submission checklist

- The theory's scope is checked against the middle range definition.
- The search terms are stated as the prompt specified them.
- Limiters, result counts and the narrowing process are described briefly.
- The development approach is named from the recognised set.
- The starting material, concept identification and relational statements are traced.
- Any validation or testing step is reported, or its absence stated.
- A complete APA reference is given, for a peer-reviewed article.
- A short critical judgement closes the post.
- Methodological claims are cited to a source other than the article itself.
