ABC Model (REBT)
Definition
The ABC model is the foundational framework of REBT, explaining the relationship between events, beliefs, and emotional/behavioural consequences.
- A (Activating event) — The external situation, trigger, or adverse circumstance
- B (Belief) — The evaluative/imperative thought the person has about the event. This is the crucial link in REBT.
- C (Consequence) — The emotional and behavioural outcome. This flows from B (the belief), not directly from A (the event).
The model is often extended to include:
- D (Disputation) — Challenging and examining the irrational belief
- E (Effective new belief) — The rational alternative belief
Clinical Significance
The ABC model makes explicit a key principle: people are not upset by things, but by the views which they take of them (paraphrasing Epictetus, whom Ellis drew on philosophically).
This means:
- Two people can experience the same activating event (A) but have very different consequences (C) because they hold different beliefs (B)
- Changing C (emotional outcome) is not primarily about changing A (we cannot always control events), but about examining and shifting B (which we can control)
- The belief is the leverage point for therapeutic change
How Different Frameworks Use It
| Framework | Application |
|---|---|
| REBT | Central model; the B→C link is paramount. Focus is on identifying irrational beliefs and replacing them through disputation. |
| CBT | Similar structure, but often focuses on “automatic thoughts” and their accuracy rather than core evaluative beliefs. |
| ACT | Would acknowledge the model but emphasise psychological flexibility in relation to B (learning to hold it lightly) rather than changing it. |
Potential Confusions
-
B is not just thought content; it is evaluative stance — “My partner was late” (factual) vs. “My partner should never be late, and it’s awful that they were” (evaluative belief about the fact).
-
Multiple B’s about one A — A client may hold several beliefs about a single event, ranging from inference to evaluation. Part of the therapist’s skill is clarifying which beliefs are the operative ones.
