The ABC Model of CBT, With A Real Example

Your friend Priya texts "can we talk later?" at 2:15pm. By 2:17 you've decided she's upset with you, replayed the last three conversations you've had, and started drafting an apology for something you're not even sure you did. By 2:40, when she calls to ask if you want to split a birthday gift for someone else, the two minutes of dread turn out to have been entirely unnecessary.

It's tempting to say the text caused the dread. The ABC model, developed by Albert Ellis as the foundation of rational emotive behavior therapy and later folded into standard CBT, argues that's not actually what happened.

What A, B, and C Actually Stand For

A is the Activating event. Something that happens — a text message, a comment from a coworker, a look someone gives you. In the example above, A is: "Priya texted 'can we talk later?'"

B is the Belief you form about the event, often instantly and without noticing it happened. In the example, B was something like: "She only says that when something's wrong. I must have upset her."

C is the emotional and behavioral Consequence — how you felt and what you did as a result. Here, C was the dread, the mental replay of recent conversations, and drafting an unnecessary apology.

The model's entire point is this: most people experience A as directly causing C. "She texted that, so I felt dread" feels like a straight line. The ABC model inserts B in the middle and asks you to actually look at it, because B is where the distortion usually lives — and B is the only part of the three you have real control over.

A Second, Fuller Example

A: Your manager schedules an unplanned 15-minute call with no agenda listed, titled just "quick chat."

B (unexamined): "Unscheduled calls with no agenda mean bad news. I'm probably being put on a performance plan or losing the project."

C: A tight chest for the two hours before the call, difficulty focusing on anything else, a draft resignation email started "just in case," and unusually short responses to a colleague who asked an unrelated question.

Notice that C includes more than a feeling — it includes concrete behavior (the draft email, the short response) that a bystander could actually observe. That's intentional. The ABC model treats behavior and emotion as a package, both downstream of the belief.

Now the useful part: B (examined). "Unscheduled calls are also how my manager shares good news, asks quick questions, or checks in about scheduling. I have zero actual evidence this is bad news — I've just decided it is." Once B changes, from a catastrophic prediction to an honest "I don't actually know," C changes with it — not necessarily to calm, but to something closer to alert-and-waiting rather than dread-and-spiraling.

Why This Is Harder Than It Looks

The difficulty isn't understanding the model. It's catching B in the moment, because beliefs at the center of the ABC model are usually automatic and near-instant — they don't arrive as a sentence you consciously compose, they arrive as a feeling that already has a belief baked into it. See Automatic Thoughts: What They Are for more on why these are so hard to notice in real time.

The practical fix is working backward. You usually notice C first — the tight chest, the dread, the urge to draft a resignation email. From there, ask: what would I have had to believe, right before this feeling started, for this feeling to make sense? That question reconstructs B even when you didn't consciously register it happening.

This is also where certain distortions show up reliably inside B — mind reading ("she's upset with me" with zero evidence) and catastrophizing ("I'm being put on a performance plan" from an agenda-less calendar invite) are two of the most common. See Mind Reading as a Cognitive Distortion and What Is Catastrophizing? for the specific patterns to watch for once you've identified a B.

Using It In Practice

The ABC model works best written down rather than reasoned through in your head, because the whole exercise depends on separating three things your mind naturally experiences as one continuous event. Give each letter its own line. Be specific about A — not "work stress" but "unscheduled 15-minute call, no agenda." Be honest about B, even if it sounds irrational written down — the goal isn't to write the reasonable belief, it's to write the one you actually had.

A CBT thought record is effectively a more detailed version of the ABC model — it adds a D and E (disputing the belief, and the new emotional effect) to the same three-part structure, which is worth using once you've gotten comfortable identifying A, B, and C on their own.

A Third Example Where B Is Less Obvious

The stove and manager examples both involve a fairly identifiable belief once you look for it. Some situations are messier. Say your partner sighs while you're telling them about your day. A: partner sighs mid-conversation. The obvious, fast belief might seem to be "they're bored of me," but a closer look often reveals a second, quieter belief layered underneath — something like "if someone I love is bored of me, that means the relationship is in trouble," which is actually the belief carrying most of the emotional weight in C.

This is worth naming because sometimes the first belief you identify is real but incomplete — it's a surface belief sitting on top of a deeper one, and the deeper one is usually what determines how intense C actually is. A sigh interpreted as "they're tired" produces mild C. The same sigh interpreted as "they're bored of me, which threatens the relationship" produces a much larger C — hurt, defensiveness, maybe picking a fight about something unrelated ten minutes later. Getting to the second, deeper belief usually takes one more round of "and if that were true, what would that mean?" after you've identified the first one.

This layering is one reason the ABC model rewards repetition rather than a single pass. The first belief you write down is a reasonable starting point, not necessarily the final answer.

Common Mistakes When Using The ABC Model

The most frequent mistake is writing A too broadly — "had a bad day at work" instead of the specific triggering moment. A broad A makes it almost impossible to isolate a clean B, because there are potentially a dozen beliefs tangled up across a whole day rather than one belief attached to one event.

The second common mistake is writing B as a feeling rather than a belief — "I felt anxious" is a C, not a B. A belief is a sentence you could argue with, something with a truth value, like "this means I'm going to lose my job" or "she's definitely upset with me." If what you've written under B could just as easily sit under C, it hasn't actually been identified yet.

The third mistake is skipping straight to trying to feel better without ever writing B down explicitly. It's tempting to jump from A to "I should calm down" without doing the work of naming what you actually believe. That skip is exactly what keeps the same pattern recurring — you can talk yourself down once, in the moment, but without identifying the belief, the same automatic sequence fires again the next time a similar A shows up.

Extending The Model With D And E

Once A, B, and C feel comfortable to identify, Ellis's original model adds two more letters worth knowing, even in an abbreviated form. D is Disputing — actively arguing with B using evidence, the way the manager and stove examples did above. E is the new Effect that results once B has actually shifted — not the same as C, because C was the consequence of the original, unexamined belief, while E is what replaces it once the belief has been genuinely updated.

The reason this extension matters is that stopping at C can accidentally turn the ABC model into just an explanation for why you feel bad, without a built-in mechanism for feeling differently. Adding D and E turns the same three-letter observation into a complete four-step tool — notice the belief, dispute it, and log what actually shifts as a result. That log becomes useful evidence the next time a similar A shows up, since you'll have a written record of a belief that felt completely certain in the moment and turned out to be wrong or exaggerated once examined.

Frequently Asked Questions

What does ABC stand for in CBT?

Activating event, Belief, and Consequence. The model, originally from Albert Ellis's rational emotive behavior therapy, illustrates that the belief formed about an event — not the event itself — determines the emotional and behavioral consequence.

Can you give a simple ABC model example?

A: your friend doesn't reply to a text for six hours. B: "They're ignoring me on purpose." C: hurt feelings and a passive-aggressive follow-up text. If B had instead been "they're probably just busy," C would likely have been mild curiosity instead of hurt.

What is the difference between the ABC model and a CBT thought record?

The ABC model is the three-part core concept. A full CBT thought record extends it with two more steps — disputing the belief with evidence, and recording the resulting change in feeling — making it a more complete working tool for actual practice.

How do I find my B if I don't consciously notice having a thought?

Work backward from C. Notice the feeling or behavior first, then ask what belief would have had to be true right before that feeling started for it to make sense. That question usually surfaces the belief even when it happened too fast to consciously register.

Is the ABC model the same as the ABC model in behaviorism (antecedent, behavior, consequence)?

No, though the letters overlap. The behaviorist ABC model (used in applied behavior analysis) tracks antecedent-behavior-consequence for observable behavior. The CBT ABC model developed by Albert Ellis inserts a belief between the event and the consequence, focusing on the internal cognitive step rather than external behavior alone.
