Ecological momentary intervention

What it is

EMI is a delivery format, not a single therapy. It means delivering treatment components in everyday life, in real time and in the person's natural settings, usually by smartphone, either standalone or as a supplement to existing treatment. It is closely tied to ecological momentary assessment…

Format

• Phase 0: Suitability, consent and set-up (1 session or part of one).
• Phase 2: Collaborative feedback (one or more sessions).

Who practises it, and how they are trained or regulated

• Research versus clinical status (as of October 2026, per the sources listed; the most recent is dated 2023). EMI remains mainly a research-stage method. A 2021 scoping review found that clinical validation was at an early stage: 9 RCTs among the included studies. In the multicentre INTERACT trial of ACT-DL in early psychosis, ACT-DL plus treatment as usual did not beat treatment as usual on the primary…

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?
• Does it involve fasting, a special diet or 'detox'? Have you discussed this with your doctor?
• 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

• Confusion over items. A phone that is shared or monitored by others. Disabled notifications.
• Unsustainable promises. Data piling up unreviewed. Messaging through the app turning into an unbounded on-call channel.
• Monitoring fatigue, and "flat" responding that suggests answers given by rote. Drop or pause monitoring if its burden outweighs its use.
• Loss of a felt connection when prompts stop. Data left on a platform without a decision. Clients who want to keep self-monitoring obsessively.
• Clients or colleagues treating a dashboard score as a diagnosis. Automation bias in yourself. Location tracking with abuse or legal implications.

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.
