The one-line answer

Cognitive analytic therapy (CAT) is a brief, collaborative, integrative psychotherapy built by Anthony Ryle in the UK. It maps how problems are maintained by reciprocal role procedures (RRPs) and three target problem procedures — traps, dilemmas and snags — and then works them through a shared reformulation letter, a sequential diagrammatic reformulation (SDR) map, recognition, revision via exits, and a planned ending with goodbye letters. It is not "CBT with an extra letter". Evidence is moderate and growing — Chanen for youth, Clarke for adult personality disorder, Hallam's meta-analysis for acceptability and durability.[1][2][4]

Meet the patient

A 31-year-old nurse has cut herself the night before every breakup she has ever had. Each relationship ends the same way: she feels controlled, she pushes back, the partner withdraws, she panics, and the blade closes the distance. She can describe the pattern fluently and still cannot stop it. "I know exactly what I'm doing," she says. "I just can't not do it."[6][11]

The registrar books her for "long-term therapy". The examiner's question is sharper: what brief, structured, collaborative treatment is built precisely for a patient who can see her own loop but cannot exit it? That is CAT's reason to exist.[3][11]
