What it is

What it is. Electrodermal activity (EDA) is the change in the skin's electrical resistance (or its inverse, conductance), largely a reflection of sweat-gland activity driven by the sympathetic nervous system; it rises when a person is startled, frightened or emotionally engaged. In electrodermal…

Format

• The cited sources give no fixed session count or phase manual for EDA biofeedback in psychotherapy. The phases below follow the case structure BCIA asks mentored applicants to document (intake, protocol selection and adjustment, discharge) and the learning sequence in the GSR 2 manual (supervised…
• The course is not standalone: EDA work sits inside the psychotherapy, which continues before, during and after it.

Who practises it, and how they are trained or regulated

• Two uses, which the Toomim tradition combines. (1) As information for the therapist during talk therapy: Marjorie Toomim, by the account of a colleague who trained with her, often used biofeedback mainly as information for herself rather than as feedback to the patient, and relied on psychotherapy in difficult cases. (2) As a self-regulation training tool for the client: learning to notice the arousal signal and…
• Who may deliver it. It is a psychological procedure delivered by licensed health professionals, including psychotherapists, within their own scope of practice. BCIA certifies practitioners: BCB-L (entry level, licensed to treat diagnosed medical or psychological disorders), BCB-P (peak/optimal performance; holders without a licence cannot work independently with anyone who has a diagnosed disorder) and BCB-T…

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is there physical contact? Was it explained beforehand, and do you feel free to say no or stop at any point?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• Does it involve intense or unusual breathing? Have you been told about the medical conditions for which that is not advised?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• methods you are not trained to teach (refer).
• false readings from touching the wrong sensor.
• misreading of the signal as judgement; shame about sweating.
• the skill working only in the therapy room; dependence on the gadget.
• anxiety about losing the device; ending abruptly when therapy work remains.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
