Activating event, Belief, Consequence — Ellis's original frame

Activating event, Belief, Consequence — Ellis's original frame

The ABC worksheet is the simplest, oldest, and most underused diagram in cognitive therapy. Albert Ellis named it in the 1950s and Aaron Beck folded it into CBT: A is the Activating event, B is the Belief or thought about it, C is the Consequence (emotion, behavior, body state). Most clients arrive convinced A causes C — 'she didn't text back so I felt awful.' The ABC map shows it's actually A → B → C, and the leverage point is B. This worksheet asks the client to fill in one recent moment in three boxes, then add a 'D' (Dispute) row for examining the belief and an 'E' (new Effect) for re-rating the emotion. It's the gateway to thought records — many clients can't tolerate a 7-column thought record on week one but can complete a 3-box ABC in five minutes. Use it as the first cognitive worksheet you hand out, as psychoeducation in couples work where each partner can see the other's B box, and as a refresher when therapy has drifted out of the cognitive model. Pair with the cognitive distortions handout so the client has language for what their B box is doing.
Last 24–48 hours. Specific enough to play back like a video — when, where, what happened.
Just the facts. What happened, observable. 'She didn't text back by 9 pm.' Not 'she ignored me.'
What went through the mind. 'She doesn't care.' 'I'm not worth replying to.' First thoughts, even harsh ones.
Emotion (name + 0–10 rating), behavior (what you did or wanted to do), body (sensation).
What's the evidence for and against B? What's a more balanced reading? This is the active ingredient.
Re-rate the emotion after disputing. The drop is usually 10–30 points, rarely to zero — and that's the data point.
A simple cognitive model where A is the Activating event, B is the Belief about it, and C is the Consequence — emotion, behavior, and body response. Created by Albert Ellis (REBT, 1950s) and adopted into CBT. The clinical insight: A doesn't cause C; B does. Change B and C changes.
ABC is the 3-box minimum viable cognitive worksheet. A thought record is the 5-to-7-column expansion — same model, more structure for evidence-weighing and balanced thought generation. Start with ABC; graduate to thought records when the client is ready for more granularity.
Ellis's extended model. A: Activating event. B: Belief. C: Consequence. D: Disputing the belief. E: new Effect — the re-rated emotion after disputing. The DE portion is what makes ABC therapeutic rather than just diagnostic.
Yes — it's particularly clean for anger work. Anger is almost always the C produced by a 'should' or 'unfair' B box. Making the B box visible defuses the certainty that the situation alone caused the anger.
Both. Ellis developed it as the core of REBT. Beck and later CBT theorists adopted it as the foundation of the cognitive model. The original ABC is more confrontational about 'irrational' beliefs; the CBT version emphasizes balanced re-evaluation. Same diagram, slightly different attitude.
