Of everything in Cognitive Analytic Therapy, the reformulation letter is the part clients remember. It’s also the hardest to explain until you’ve received one — so here’s what it is, what it does, and what it doesn’t.

What it is

Early in a course of CAT — usually around the fourth session — I write you a letter. Not a clinical summary, not notes: a letter, addressed to you, telling the story of how you came to be where you are. It draws together what you’ve told me — your history, the patterns you keep hitting, the feelings underneath them — into one coherent account, in plain language.

What’s in it

A reformulation letter usually traces three things: where the patterns came from (what you learned, and why it made sense at the time), how they show up now (the reciprocal roles and loops that keep repeating), and what we’re going to work on together. It’s written to you, in the second person — “you learned that…”, “you find yourself…” — not about you in the third.

What it does

Its real work is to turn scattered, often shameful-feeling difficulty into a story that makes sense. Most people arrive carrying some version of what’s wrong with me? To see your life set out as a pattern — an understandable response to what you lived through, not a catalogue of failings — usually lifts something. It also gives the therapy a shape: the letter, and the diagram that goes with it, become a reference point we return to, and a map you can use to catch the patterns as they happen.

What it doesn’t do

It isn’t a diagnosis, and it isn’t my verdict on you — it’s a draft we revise together until it reads true, and you’re free to push back on anything that doesn’t fit. It doesn’t fix anything by itself, either: recognising a pattern is the beginning, not the end, and the change comes later, from practising the exits. And it isn’t the point where the work is “done” — it’s the point where it properly starts.

Why I write one for every client

Because being seen clearly, and having your experience put into honest words, is itself part of how people change. The letter says: I’ve heard you, this makes sense, and here is what we’ll do about it. For the patterns that don’t shift on their own, that turning point matters.

What it’s like to receive one

People often go quiet reading it — some are moved, some relieved, occasionally a little exposed. All of that is welcome; we read it together, and your reaction becomes part of the work. If something’s wrong, we change it. It’s yours.
