ACT session notes: the hexaflex as a documentation frame

Good ACT therapy notes capture movement across the six hexaflex processes — where the client showed flexibility, rigidity, or shift, not just what was discussed. A consistent documentation habit also protects you clinically and satisfies your professional body's record-keeping standards.

Why standard SOAP notes feel awkward in ACT

Most note formats were designed for problem-focused, symptom-reduction models. SOAP works well when you're tracking symptom severity week to week, but ACT is a process model — you're tracking psychological flexibility, not only whether the PHQ-9 score dropped.

This creates a documentation mismatch. A therapist writing SOAP notes after an ACT session often ends up with a vague "Assessment" — something like "client continues to struggle with experiential avoidance" — accurate, but clinically thin. It doesn't capture which process you worked on, what intervention you used, or what shift you observed.

The hexaflex gives you a ready-made framework already embedded in your clinical model.

The six processes as documentation anchors

The six ACT processes — acceptance, defusion, contact with the present moment, self-as-context, values, and committed action — each describe something observable in session. When you write notes, you're answering: which of these did we work on, what did I observe, and what's the clinical implication?

Here's how each maps to a documentation focus:

Acceptance — Note whether the client moved toward or away from difficult internal experiences. Did they engage with an exercise, or did the session reveal an avoidance pattern you hadn't seen before?

Defusion — Record which techniques were used (e.g., leaves on a stream, naming the story) and the client's response. A brief note on whether they could hold thoughts more lightly — or couldn't yet — is clinically meaningful.

Present-moment contact — Was the client able to stay with here-and-now experience, or did they pull toward rumination or worry? Note any mindfulness exercises used and the client's observed engagement.

Self-as-context — Harder to document briefly, but worth noting when it's the focus. Did the client show any capacity to observe their experience from a perspective beyond their fused self-narrative?

Values — Record any values clarification work. If a client named a value or connected an avoided behaviour to a value conflict, write it down. These notes are useful when you return to values in later sessions.

Committed action — Document any between-session commitments, how specific they were, and whether previous commitments were reviewed. This is the part of your notes most likely to be scrutinised if your work is ever reviewed.

A practical note structure for ACT

You don't need to address all six processes in every note — that would be formulaic and slow. A workable structure might look like this:

1. Session focus — one or two sentences on what the session centred on (e.g., defusion from "I'm fundamentally broken" story; values work around parenting).
2. Hexaflex process(es) addressed — name them explicitly. This keeps notes process-focused rather than content-focused.
3. Client response — what you observed, including resistance, engagement, or unexpected material. Keep this behavioural and specific.
4. Formulation note — a brief update on your working hypothesis. Has anything shifted in how you understand this client's flexibility profile?
5. Plan — what you intend to focus on next session, and any between-session practice agreed.

This structure maps reasonably well onto BIRP (Behaviour, Intervention, Response, Plan) or DAP (Data, Assessment, Plan) formats, both of which are used in UK private practice and generally accepted by many insurers — check with yours, as requirements vary.

What to include when risk or safeguarding is present

ACT's acceptance stance can sometimes be misread — by clients, supervisors, or third parties — as passive. If a client is working with suicidal ideation using defusion and acceptance techniques, your notes need to make the clinical rationale explicit. Document that you assessed risk, note the specific ACT approach you're using (e.g., defusion from urges rather than suppression), and record any safety planning alongside it.

If you're keeping a safeguarding concern log, cross-reference it in your session note so there's a clear audit trail. Your professional body's guidance — whether BACP, UKCP, HCPC, or another — sets out what your records need to demonstrate. Check current requirements directly with them, as standards are updated periodically.

Outcomes data alongside process notes

ACT is sometimes criticised for being hard to measure. It isn't — but you need to choose measures thoughtfully. PHQ-9 and GAD-7 track symptom severity and are useful for demonstrating change to referrers and insurers. The AAQ-II (Acceptance and Action Questionnaire) is one of the most commonly used ACT-specific measures in research and practice, tracking psychological flexibility directly (see Hayes et al. for the validation literature).

If you're collecting PHQ-9 and GAD-7 regularly, outcomes tracking that includes reliable change index (RCI) calculations can help you identify whether change is clinically significant rather than just statistically present — a distinction that matters in ACT, where symptom scores may fluctuate while flexibility genuinely improves.

Honest limitation: hexaflex framing takes practice

Using the hexaflex as a documentation frame is clinically coherent, but it requires you to think in process terms during or immediately after the session. Early on, this can feel like an extra cognitive step — particularly if you trained in a different model. Some therapists keep a hexaflex diagram on their desk as a prompt; others build shorthand into their note templates. Either way, expect a few weeks of adjustment before it feels natural.

There's also a practical tension: process-focused notes are richer clinically, but they take longer to write. If you're seeing six or more clients a day, that time adds up. Finding a format that's thorough enough to be useful but brief enough to be sustainable is a genuine trade-off, not a solved problem.

Writing letters and supervision summaries from ACT notes

Well-structured ACT notes make downstream tasks easier. A GP letter or referral summary is simpler to draft when your notes already contain a clear formulation, a record of processes addressed, and measurable outcomes. Clinical letters — whether to a GP, insurer, or court — should translate your clinical notes into language the recipient can use, without losing the ACT framing entirely.

For supervision and CPD, your notes are your primary evidence of reflective practice. If you're working toward BACP accreditation or renewal, process-focused, theoretically grounded documentation is a practical asset.

Where Sorca fits

Sorca's AI clinical scribe drafts notes in your modality, including formats like BIRP and DAP that map well onto ACT work. Audio is processed in the browser and never stored; you review and edit before anything enters a client record. PHQ-9 and GAD-7 are collected between sessions via the free client companion app, so scores arrive in context rather than being entered manually in-session. If you're writing a lot of ACT notes and want a starting draft that reflects your modality rather than a generic template, it's worth a look.
