What it is

The TTM is a framework, not a single therapy. It does not supply its own techniques. It tells the clinician when to use which kind of change activity, drawn from many therapy systems, according to the client's readiness for one specific problem. It was developed from the late 1970s by James…

Format

• Typical session count and format. The TTM prescribes no fixed course. It overlays whatever treatment is being given, and stage is reassessed as the work goes on.
• The SAGE entry by Prochaska says tailored TTM counselling typically takes about three sessions of 20–45 minutes, guided by evidence-based algorithms.

Evidence status, as the guide reports it

• The SAGE entry by Prochaska says tailored TTM counselling typically takes about three sessions of 20–45 minutes, guided by evidence-based algorithms.

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• 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

• Practical barriers (cost, transport, stigma) that you can help remove.
• The exercise turning into blame or guilt-tripping. Keep it exploratory.
• Feedback that reads as generic. Personalise it to the client's own answers.
• Working on a deeper level the client has not agreed to, which is a mismatch.
• Substitutes that are themselves risky. Track whether temptation ratings fall.

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.
