SOAP notes were built for medicine, not for therapy
SOAP is the most widely taught note format in healthcare and the most awkward fit for psychotherapy. Three of its four sections work fine. The fourth — Objective — asks for something a talking therapy does not straightforwardly produce, and how a practice resolves that says a lot about the quality of its records.
SOAP comes from Lawrence Weed's problem-oriented medical record, developed in the 1960s to impose structure on physician notes. The logic is medical: the patient reports symptoms (Subjective), you measure and observe (Objective), you interpret (Assessment), you decide what to do (Plan). For a physician examining a swollen knee this maps cleanly onto reality.
For a fifty-minute psychotherapy session it maps less cleanly, and most SOAP notes in behavioral health show the strain in the same place.
Subjective
What the client reports: presenting concerns, symptom changes since last session, relevant life events, their account of how things have been. Direct quotes are useful here where they capture something a paraphrase would lose.
The failure mode is length. The Subjective section is the easiest to write and the least valuable per line, so it swells while the Assessment shrinks. A note with eight sentences of Subjective and one of Assessment has recorded what happened and not what you thought about it — and the Assessment is the part that demonstrates clinical work.
Objective — the hard one
In medicine this is vital signs, examination findings, laboratory values. In psychotherapy the question "what did you objectively measure?" has no comfortable answer, and practices resolve it in one of three ways.
- Leave it nearly empty. Common, and it produces notes with a conspicuous gap where a reviewer expects content.
- Fill it with subjective content. Also common, and it collapses the distinction the format exists to make.
- Use it for genuinely observable material. Correct, and requires knowing what qualifies.
What legitimately belongs in Objective for a therapy session:
- Mental status observations — appearance, grooming, motor activity, speech rate and volume, observed affect, orientation. These are things you saw, not things you inferred.
- Outcome measure scores — a PHQ-9 of 14 is about as objective as behavioral health data gets.
- Attendance and punctuality, where clinically relevant.
- Observable behaviour in session — tearfulness, avoidance of a topic, sitting with coat on throughout, checking phone repeatedly.
- Session duration and modality.
The distinction that keeps it clean. "Client appeared anxious" is an inference. "Client's leg bounced continuously, spoke rapidly, and asked twice whether the session was being recorded" is an observation. The first belongs in Assessment. The second belongs in Objective, and it is more useful, because a later reader can form their own view.
Assessment
Your clinical thinking: how you interpret what the client reported and what you observed, progress against treatment goals, changes in risk, hypotheses about what is maintaining the problem, and any revision to the formulation.
This is the section that carries the note. It is also the one most often reduced to a sentence like "client continues to struggle with anxiety" — which restates the Subjective rather than interpreting it. If an auditor is looking for evidence that a licensed clinician exercised judgement, this is where they look, and a note without a substantive Assessment reads as a transcript.
It is also where the treatment plan goal belongs. Naming the goal the session advanced, and saying whether it advanced, is the single most valuable sentence in most notes.
Plan
What happens next: focus for the following session, homework or between-session tasks, referrals, coordination, any change to frequency or modality, and when the next outcome measure is due. A Plan that says only "continue weekly therapy" for eighteen months is a plan in name only, and it is exactly the pattern that raises medical-necessity questions.
When SOAP is the wrong choice
SOAP is a reasonable default in integrated and medical settings, where colleagues reading the chart already know the format and where genuinely objective data is routinely present. It is a poorer fit in two situations.
Where the Objective section will be chronically thin. Private-practice talking therapy without routine measurement produces SOAP notes with a hollow section, and the honest alternative is DAP, which collapses Subjective and Objective into a single Data section and stops pretending the distinction is load-bearing.
Where the intervention needs foregrounding. SOAP has no section that asks explicitly what the clinician did. Interventions end up scattered through Assessment and Plan, which is precisely the content payers most want to see. BIRP solves this by giving the intervention its own heading.
A worked comparison
The same session, briefly, in SOAP:
S: Client reports a difficult week; conflict with manager Tuesday, described "spiralling" afterwards. Sleep 4–5 hours nightly. Denies SI.
O: On time, casually dressed, well groomed. Speech normal rate. Tearful when describing the conflict. GAD-7 administered: 13 (down from 16).
A: Anxiety symptoms improving on measure despite a difficult week, which client had not noticed until shown the trend. Goal 2 — "identify and test catastrophic predictions before acting on them" — partially advanced; client generated alternatives with support but not independently. Avoidance of workplace conflict remains the maintaining factor.
P: Continue weekly. Thought record on the manager interaction before next session. Reassess GAD-7 in four sessions; consider step-down if below 10 sustained.
Note what makes this defensible: the Objective section contains only observed material, the Assessment names a goal and says what happened to it, and the Plan has a criterion rather than an intention.
Format is not the point
Worth saying at the end because it is easy to lose. No payer requires SOAP. No licensing board mandates it. What is required is that the note evidences a medically necessary service delivered by a qualified clinician against an active treatment plan. SOAP is one scaffold for producing that; so are the alternatives. A practice arguing about formats while none of its notes name a treatment goal is optimising the wrong layer.
Templates and the copy-forward problem
Every EHR offers a way to carry the previous note forward, and it is the single most damaging feature in behavioral health documentation.
Copy-forward produces notes that are internally plausible and collectively worthless. A reviewer pulling six sessions and finding the same Objective section verbatim in all six, with only the Subjective varying, concludes that the observations were not actually made. Worse, copy-forward propagates errors: a mental status observation entered once in error appears in every subsequent note until someone notices, which may be years.
Templates are not the same thing and are entirely legitimate. A template supplies empty headings and prompts; copy-forward supplies last week's answers. The first speeds up documentation, the second replaces it.
How long should it be?
Shorter than most people write. A routine session note that runs to a page is usually carrying narrative rather than reasoning. Eight to twelve sentences across the four sections is a complete, defensible record for most outpatient encounters — with genuine exceptions for intakes, crises and significant clinical events, which legitimately need more.
Where SOAP came from matters
Knowing the format originated in a 1960s effort to make physician notes auditable explains most of its quirks — including why it privileges observation over interpretation and why it has no section for what the clinician did. It was built for a discipline where the doing is a procedure recorded elsewhere. Behavioral health has no such elsewhere, which is the root of the awkwardness.
