It is eleven at night and you are on somebody’s website.
The page says trauma-informed. It says somatic. It probably says integrative, and holistic, and there is a photograph taken in good light against a plant.
And you have no way at all to tell whether a trauma-informed therapist with that page behind them has eight years of supervised clinical practice and a real caseload, or a weekend in a hotel conference room and a certificate printed on nice paper.
That is the actual problem, and it is not your fault for not solving it. The words are doing no work. So this piece is not a definition. It is three questions you can ask, why each one discriminates, and — because I would rather you had this than a slogan — what the research actually shows about how much your choice of practitioner matters. Including where that research is inconvenient for someone in my position.
Why the label tells you almost nothing
“Trauma-informed” is not a protected term. In Portugal, across most of the EU, and in most of the United States, there is no register, no licensing body, and no legal standard governing who may print it.
That means the phrase is not evidence. It is marketing copy, and it costs nothing to write.
Some of the people using it have done extensive supervised training and continue to be supervised. Some have done a short online course. Both groups have the same words on the same kind of page, and from the outside at eleven at night, they are indistinguishable.
So the question cannot be do they say it. It has to be what do they do — and specifically, what do they do that someone who had not done the work would be unable to fake in conversation.
What a trauma-informed therapist actually does — and what the evidence says about choosing one
Before the questions, the uncomfortable part. If you have been reading about this, you have absorbed a background assumption: that finding the right practitioner is the decisive variable, and that the search is therefore the most important thing you will do.
The largest dataset available does not support that as strongly as the discourse implies.
Firth and co-workers built a three-level model on 26,888 patients, seen by 462 therapists, across 30 clinics — an unusually large and well-structured sample for this question [1]. They found a therapist effect of 3.2%: the proportion of variation in outcome attributable to which individual therapist you saw [1].
They also found a clinic effect of 8.2% — significantly larger than the therapist effect [1]. Where you were treated explained more of the variance than who treated you.
And then the detail that matters most. When explanatory variables were added, the clinic effect collapsed from 8.2% to 1.9%, while the therapist effect barely moved, from 3.2% to 3.4% [1]. Most of what looked like “some clinics are better” turned out to be the socioeconomic mix of the patients walking through the door. The therapist effect, by contrast, was small and stable — it survived the controls.
Read that honestly in both directions, because both directions are true.
It is real. 3.2% is not nothing when you are the person in the chair, and unlike the clinic effect it did not dissolve under scrutiny. Who you work with matters.
And it is smaller than you have been led to believe. Anyone telling you that the right practitioner will change everything is selling past the evidence. Most of what determines how this goes is you, your circumstances, and how long you stay.
One more figure, because it points somewhere useful. Zimmermann and colleagues examined 707 patients across 66 therapists and found that 5.7% of the variance in dropout was attributable to the therapist, an effect that held after controlling for how unwell people were at the start [2]. Negative expectations going in also predicted dropping out [2].
So the therapist’s largest measurable effect may not be on whether you get better. It may be on whether you stay long enough to find out.
Which reframes the whole exercise. You are not hunting for a person who will fix you. You are screening for someone you will not quietly abandon in week six — and that is a much more tractable thing to test for.
The three questions
Ask these on a consultation call. All three take under five minutes. None of them can be answered from a marketing page.
Question 1 — “What happens when you get it wrong in a session?”
Not do you get it wrong. Everyone does. What happens afterward.
Why it discriminates. A practitioner who has never seriously considered this will hear the question as an accusation and will defend. A practitioner who works this way will have a procedure, will describe it plainly, and will not need you to reassure them while they do it. You will know within about eleven seconds.
What the evidence says. Eubanks, Muran and Safran meta-analysed 11 studies covering 1,314 patients and found that repairing a rupture in the therapeutic alliance was moderately related to good outcome, r = 0.29, d = 0.62, p = 0.003 [3].
Now the part that most people in my field do not quote.
A newer multilevel meta-analysis by Babl and co-workers restricted itself to studies using direct measures of rupture, and found that ruptures themselves were associated with poorer outcomes, r = −0.21 [4]. That analysis rests on four publications and 301 clients [4], which is a small evidence base, and I would rather tell you that than let the finding sound bigger than it is.
Put the two side by side, and the picture sharpens rather than blurs.
There is a fashionable idea in this industry that growth happens in rupture. It is not. Ruptures, left alone, predict things going worse [4]. It was never the rupture. It is the repair. A practitioner who romanticizes rupture has read the first half of the literature and stopped.
And one more, against my own interest. The same 2018 paper ran a second meta-analysis: did training therapists in rupture resolution improve their patients’ outcomes? Across six studies and 276 trainees, there was no significant effect, r = 0.11, p = 0.28 [3].matters
Which is worth holding next to every certificate on every about-page, including mine. Training is weaker evidence of capability than the industry’s marketing assumes. What the person actually does in the room is the thing.
Question 2 — “What is outside your scope, and who do you send those people to?”
Why it discriminates. Capacity is a specification, not a virtue. A cable rated for ten amps does not become a bad cable when you push thirty through it — it becomes a fire, and the failure was that nobody checked the rating.
A practitioner with a real referral network has worked out their own rating. They have hit their limit, noticed, and built the relationships that handle what they cannot. That takes years, and you can’t improvise it on a phone call.
A practitioner who can hold everything is telling you one of two things: that they have very little experience, or that they are not being straight with you. Neither is what you want when you are about to hand over your rawest material.
What a good answer sounds like: specific conditions named, specific onward routes, no defensiveness, and some evidence they have actually made those referrals.
Red flag: any version of “my method addresses all of that.”
Question 3 — “What does the evidence for your method actually show — including where it’s thin?”
This is the discriminating question, and almost nobody passes it.
So let me answer it about my own primary method, in public, and you can use this as the standard.
Somatic Experiencing.
Brom and colleagues ran what is described as the first randomized controlled study of Somatic Experiencing for PTSD: 63 participants, randomized to 15 weekly sessions or a waitlist [5]. The results were good — PTSD symptom severity d = 0.94 to 1.26, depression d = 0.70 to 1.08, holding at follow-up [5].
Those are large effect sizes, and I am not going to pretend otherwise. But you should know two things about that design. The comparator was a waitlist, not an active treatment [5] — and waitlist controls reliably produce larger effect sizes than comparing against a real alternative therapy. And 63 participants is a small trial.
Then Kuhfuß and colleagues ran a scoping review: they screened 83 articles and included 16 [6]. Their conclusion was preliminary evidence of positive effects — and, in their own words, that the overall study quality is mixed, with risk-of-bias concerns on Cochrane assessment, and an explicit call for more unbiased randomized controlled research [6].
So the honest answer to “is Somatic Experiencing evidence-based?” is:
Promising. Thin. Mixed in quality. And considerably less settled than the way it is marketed.
I use it anyway, and I will tell you exactly why: the proposed mechanism is coherent, the one randomized trial that exists is positive [5], and I do not run a practice that depends on it alone. That is a defensible position. “Yes, it’s evidence-based” is not.
If a practitioner cannot produce an answer with that shape about their own method — the good and the thin, with the design named — you have learned what you came to learn.
Red flags, briefly
- Certainty about what is wrong with you before they have met you properly.
- A method that addresses everything.
- Pressure to commit to a long, expensive package on the first call.
- Defensiveness when you ask any of the three questions.
- No named limits, no referral network.
- Visible discomfort with the word “evidence.”
And the counterweight, because this shouldn’t make you paranoid: warmth is not a red flag. Nor is a practitioner who has done their own work and says so, or one who admits uncertainty. Those are usually the signs you want. Precision is not the same thing as coldness, and you are allowed to like the person.
What it costs you to skip this
You are considering handing your rawest material to a stranger with a website.
If the rating is wrong — if you bring thirty amps to someone built for ten — the result is not usually dramatic. It is quieter than that. It is six sessions that go nowhere, a slow conclusion that you are unhelpable, and a year before you try again. That is the real cost, and it is common, and it is largely preventable with five minutes of questions.
You would check the amperage on a cable.
If you want to ask me these questions
A Breakthrough Session is 90 minutes, one-to-one, €222.
Ask me all three on the call. I will answer them, including the third one, which I have just answered above in writing so you can hold me to it.
I take a limited number of these each month, and every one of them is me — there is no team and no associate.
Frequently asked questions
How do I know if my therapist is actually trauma-informed?
The term is not legally protected, so the label itself tells you nothing. Ask three questions instead: what happens when you get it wrong in a session; what is outside your scope and who do you refer to; and what does the evidence for your method actually show, including where it is thin. A practitioner who works this way will answer all three without defensiveness.
What’s the difference between trauma coaching and trauma therapy?
Therapy is a regulated profession with protected titles, licensing, and a scope that includes diagnosable mental illness. Coaching is generally unregulated and works with people who are functioning but stuck. The meaningful question isn’t the label, but whether the practitioner clearly names their scope and refers when something falls outside it.
Is Somatic Experiencing evidence-based?
Promising but preliminary. The first randomized controlled trial, with 63 participants, found large effects on PTSD symptoms, but used a waitlist control and a small sample [5]. A 2021 scoping review of 16 studies found preliminary positive evidence while stating that overall study quality is mixed and calling for more unbiased randomized trials [6].
What should I expect in a first session with a somatic practitioner?
A first session should establish what you are bringing, the practitioner’s scope, and how they work when something becomes overwhelming. You should not be pressured into a long package on the first call, and you should leave knowing what happens next and what it costs.
What are red flags in a trauma practitioner?
Certainty about your diagnosis before meeting you properly; a method that claims to address everything; pressure to commit to an expensive package on a first call; defensiveness when questioned; no named limits or referral network; and discomfort with the word “evidence.”
