NR-668 Week 3 is where the capstone starts grading your clinical reasoning directly, through a written account of a de-identified psychiatric encounter that has to carry an assessment, a differential, and a formulation the reader can follow from evidence to conclusion. Your section may print this as NR 668 or NR668; it is the same course. Chamberlain publishes no syllabi outside Canvas. The placement here is our teaching judgment from the course's catalog arc; your section's rubric decides what your week actually asks.
What NR-668 Week 3 asks for
The territory is the psychiatric interview turned into an argument. A capstone reader wants three things visible on the page. First, an assessment that records what was observed rather than what was concluded: mental status described in behaviour and speech, not in adjectives borrowed from the eventual diagnosis. Second, a differential that contains more than one live candidate and shows why each survived or fell. Third, a formulation, which is the part students most often omit and the part that separates capstone writing from the documentation they have been producing since their first practicum.
Formulation is not diagnosis restated. It is the account of why this person developed this presentation at this point in their life, drawing on what predisposed them, what precipitated the episode, what is keeping it going, and what protects them. A reader can tell within a paragraph whether a student has understood that distinction, because a diagnostic label answers what and a formulation answers why now.
The deliverable at this point in an eight-week capstone is usually an encounter write-up of two to four pages against a structured template, sometimes with a short posted case discussion beside it. Every identifying detail comes out before the first draft, not after. If your section runs a discussion this week, treat the post as final on submission, because Canvas does not reopen it. And the encounter is yours: we help you write the analysis of a case you saw, and we neither supply cases nor touch your clinical documentation.
The NR-668 Week 3 method, step by step
Six moves that take a visit you sat in on and turn it into a formulation that holds together.
-
Build the case skeleton before you open the template
Age band, presenting concern in the patient's own framing, duration, trajectory, and what made them come now. Five lines. If the skeleton is thin, the paper will be thin, and no amount of template filling repairs it later.
-
Write observation and interpretation in separate passes
First pass records only what was seen and said: rate of speech, movement, content of thought, orientation, stated mood against observed affect. Second pass interprets. Mixing the passes is what produces a mental status exam that has quietly assumed the answer.
-
Build the differential from what would change management
Three to four candidates, each one chosen because confirming or excluding it would alter what happens next. Include the medical and substance related possibilities explicitly, since a psychiatric write-up that never considers them reads as incomplete regardless of how well the rest is argued.
-
Argue each candidate against stated criteria
For every candidate, name the features present, the features absent, and the duration or course requirement that decides it. Cite the diagnostic manual edition your program uses by name and edition. Do not assert a criterion count you have not checked.
-
Write the formulation in four moves
Predisposing, precipitating, perpetuating, protective. One short paragraph each, each grounded in something the encounter actually produced. This is the section a capstone rubric usually pays most for and the one most drafts leave until they are out of words.
-
Close on what the formulation changes
Say what the reasoning implies for the next step: further assessment, collateral information, a monitoring interval, a referral. A formulation that leads nowhere reads as an exercise, and this is a capstone.
A layout and word budget for an encounter analysis
The frame our tutors keep beside a psychiatric write-up of roughly 1,200 to 1,500 words. It is our own outline rather than a university form, and your week's rubric outranks it wherever the two disagree.
| Section | What belongs in it | Word target |
|---|---|---|
| Presentation in brief | Age band, setting, referral route, the concern as the patient framed it, and why now. | 90 to 120 |
| History that bears on the question | Psychiatric, medical, substance, family and social history, filtered to what the differential will actually use. | 200 to 260 |
| Mental status as observed | Behaviour, speech, mood and affect, thought process and content, cognition, insight, all in observational language. | 220 to 280 |
| Differential, argued | Three or four candidates with features present, features absent, and the deciding criterion for each. | 280 to 340 |
| Formulation | Predisposing, precipitating, perpetuating and protective factors, each tied to case evidence. | 260 to 320 |
| Next step and reasoning | What the formulation implies for assessment, collateral, monitoring or referral, with the interval named. | 110 to 150 |
Evidence craft for diagnostic reasoning
Cite the criteria set you are applying, by name and edition. Diagnostic thresholds are revised, and specifiers move between editions. A write-up that argues criteria without naming the source is asking the reader to take your memory on trust in the one place they will not.
Screening instruments have properties, so report them. If you cite a rating scale score, name the instrument, the version, the score and what the score means in that instrument's own terms. A number without its scale is not evidence, and a scale used outside the population it was validated in needs that limitation stated in the sentence.
Collateral is evidence with a source attached. Where information came from a family member, a record or a referring clinician, say so in the sentence that uses it. Weight follows source, and a reader assessing your reasoning has to know which claims rest on the patient's account alone.
Keep the hedge language honest. Consistent with, supports and raises the possibility of are accurate for a single encounter. Confirms and demonstrates are not, because one visit rarely settles a psychiatric question. Overconfident verbs in a formulation are the fastest way to lose a reasoning row you had otherwise earned.
Five mistakes that cost points in this week's territory
- A mental status exam written backwards from the diagnosis. Once the observations start using diagnostic adjectives, the reasoning has nothing independent left to stand on.
- A differential with one real candidate and two decoys. Listing possibilities you never seriously weighed is visible, and it scores worse than a shorter differential argued properly.
- Medical and substance causes skipped entirely. Their absence is read as an omission in clinical thinking rather than as a judgement that they were unlikely.
- Formulation replaced by a summary paragraph. Restating the history in shorter form answers what happened. The rubric row is asking why this person, why now.
- Identifying detail left in. Dates, employers, unusual circumstances and small locations re-identify a patient in combination even when no name appears.
Before you submit
- Observations are stated in behaviour and speech, free of diagnostic adjectives
- The differential holds at least three candidates that would change management
- Each candidate names features present, features absent and the deciding criterion
- Predisposing, precipitating, perpetuating and protective factors each appear
- Every instrument score carries its instrument name and interpretation
- No date, place, employer or detail that could re-identify anyone survives the draft
