When I read a claim about hypnotherapy, I want to know what the researchers actually tested. Who took part? What changed? Was it still different a few months later? This page looks at some of that research and how closely it relates to the work I offer.

Hypnosis is associated with measurable changes in attention and brain-network activity. Evidence for hypnotherapy varies by condition and study quality. Expectations and the therapeutic relationship may also affect outcomes, and no individual result can be guaranteed.

The useful question is whether a study tested the concern and approach you are considering. A brain scan, a treatment trial and a client’s experience answer different questions.

Read the findings in context. A useful study invites more than one question. What was studied?: Who took part, and which approach was used? What changed?: Which outcomes were measured, and for how long? What are the limits?: How certain are the findings, and to whom do they apply?
I look at who took part, what the study measured and how long any change lasted. Then I consider how closely that work matches what I offer. Related: the evidence overview.

1. What brain imaging shows

A Stanford study by Jiang and colleagues examined brain activity during hypnosis in healthy volunteers selected for very high or low hypnotisability. Among the highly hypnotisable participants, the researchers found changes in activity and communication between areas involved in attention, body awareness and thinking about oneself.

These findings help researchers study what happens during hypnosis. They don’t show that hypnosis switches off worry, or that a particular session will help a particular person. For that, we need studies of treatment outcomes.

2. What the anxiety research found

A 2019 meta-analysis by Valentine and colleagues combined 15 studies covering 17 trials. Anxiety improved more in the hypnosis groups on average, and effects were larger when hypnosis was combined with another psychological intervention.

The review compared group outcomes. It does not give a recovery percentage or predict how many sessions you will need. The trials covered different kinds of anxiety and settings, so we still need to consider whether the approach fits your concern.

3. Evidence for gut-directed hypnotherapy

A 2025 systematic review by Thakur and colleagues found that gut-directed hypnotherapy improved overall IBS symptoms compared with waiting-list controls. Confidence in all comparisons in the review was low or very low, partly because of trial limitations and possible publication bias.

These studies tested particular treatment programmes. I offer support with IBS-related stress and coping alongside medical care, rather than a structured gut-directed programme. The IBS and stress guide explains the difference.

My support around persistent pain also stays alongside medical care. We can work on the worry, tension and sleep difficulties that accompany it. I do not diagnose pain or claim to treat its cause.

4. Hypnotisability and clinical outcomes

People differ in how they respond to hypnotic suggestions. Researchers measure this using structured tasks, but a laboratory score does not tell the whole story about whether a particular course of therapy will help.

A 2011 meta-analysis of 10 studies found a small-to-moderate association between hypnotisability and clinical outcomes, with a correlation of 0.24. The authors questioned how useful routine testing was in clinical practice. In the consultation, I also consider what you want help with, your current care and whether I am the right practitioner for the work.

So I do not rule someone out solely because of a hypnotisability score. Overall suitability still matters, including the nature of the problem, current care, risk, expectations and whether I am the right practitioner for the work.

5. Expectation is part of the work

In a 2025 experiment by Kekecs and colleagues, labelling a procedure “hypnosis” influenced participants’ reports of hypnotic depth. The authors described their findings as exploratory. This study concerned the experience of hypnosis, so it cannot establish whether a treatment improves anxiety, sleep or another concern.

That does not make the question of placebo irrelevant. Expectation, attention, context and the therapeutic relationship can influence outcomes in many forms of care. A good therapist acknowledges those factors rather than claiming every change came from a special technique.

The important bit is whether the change carries into real life. Does the body settle sooner? Does the pattern have less grip? Does the person behave differently in the situation that used to trigger them? That is where the work has to prove itself.

6. Where findings remain uncertain

The 2018 sleep review by Chamine and colleagues found some benefits but also mixed and negative findings. It called for better studies because samples were small and methods often weak.

The 2019 Cochrane smoking review by Barnes and colleagues found insufficient evidence to establish that hypnotherapy outperforms other behavioural support or quitting without help. Uncertainty should be included when discussing the options.

A memorable improvement can matter greatly to a client. It still cannot show which part of the work caused the change or what someone else can expect. Controlled research and individual reviews have different purposes.

7. How the evidence informs my work

The research points me towards a practical, collaborative style. Attention, expectation, context and the working relationship all matter, so I adapt the session to the agreed goal while staying clear about what is evidence-based and what is a working hypothesis.

My core training is hypnotherapy and NLP, and I bring in approaches from CBT, ACT and solution-focused therapy where they help. I’m not a CBT therapist and I don’t run full CBT programmes, and I keep that clear when we talk about the work.

The free consultation includes a suitability check. If your concern needs a GP, counsellor, CBT practitioner, psychiatric support or another specialist, I will explain that rather than recommend hypnotherapy indiscriminately.

In your sessions, we agree what change would matter and when to review it. I want to hear what happened at the meeting, during the evening or when the familiar worry returned. That helps us decide what to do next. It doesn’t turn one person’s experience into evidence for everyone.

If you want the shorter practical version of this argument, read does hypnotherapy actually work?. If you want to know what the process feels like before you ever book, read what to expect in your first session.

Common questions

Yes, for some uses, though the strength of the evidence varies. Research includes anxiety-related work and gut-directed hypnotherapy for IBS. The evidence is not equally strong for every claim, so a careful practitioner should distinguish what is supported, what is promising and what remains uncertain. Your own outcomes matter when deciding whether an approach is helping you, but an individual experience does not prove that it will work for everyone.
No, a hypnotisability score alone cannot tell us whether therapy will help you. We also need to consider your concern, the proposed work and whether it is suitable for you.
There isn’t a single answer across all concerns and studies. Expectation, attention and the therapeutic relationship can influence the experience of therapy. Research needs to consider those factors when evaluating an approach. In practice, we review whether the agreed concern is changing in daily life.
I do not use hypnotherapy to diagnose or treat the underlying medical condition. My support around IBS or persistent pain focuses on worry, tension, sleep and coping alongside medical care. New, severe, changing or unexplained symptoms need medical assessment. Change prescribed treatment only with the relevant clinician.
