Cognitive Triangle: Printable CBT Worksheet and 3 Examples

The cognitive triangle is the first map most clients see in CBT: what they think, what they feel and what they do, with arrows showing how each one feeds the others. This page gives you a cognitive triangle worksheet written for your client, with a situation, the three corners, a line for body sensations, a place to choose where to step in, and a reframe. Print this page or save it as a PDF and hand it over in session.

After the worksheet comes the part for you: where the CBT triangle comes from, how it relates to Padesky and Mooney's five-part model, three short worked examples (adult anxiety, teen anger, depression), how to teach it in a first CBT session, how to adapt it for children, the mistakes that make it fall flat, and how to write it up in a progress note.

Every client in this article is invented. Any resemblance to a real person is a coincidence.

Cognitive triangle worksheet

The cognitive triangle: how one moment links your thoughts, feelings and actions

Pick one moment from the past few days when your mood changed: you felt worried, upset, angry or low. Fill in what you can. Short notes are fine, and there are no wrong answers.

1. What happened?

Write it the way a camera would have recorded it: where you were, who was there, and what happened just before the feeling started.

2. Thoughts: what went through your mind?

Thoughts can be words ("I'll mess this up") or pictures in your mind. Write them the way you thought them.

3. Feelings: what did you feel?

Feelings are usually one word, such as worried, scared, sad, angry, ashamed, guilty, hurt, lonely or embarrassed. Rate each one from 0 (none) to 10 (the strongest it gets).

4. Body: what did you notice in your body?

For example a racing heart, a tight chest, a hot face, tense shoulders, an upset stomach, or feeling heavy and tired.

5. Behaviors: what did you do?

6. How the corners fed each other

7. Where could I step in?

You can start at any corner, and a change in one often changes the others. Circle one or two.

8. A different way to see it

Answer what you can.

A more balanced thought (one you can believe, not just a positive one):

9. What I'll try next time

Bring this sheet to your next session, even if it was hard to fill in. That tells your therapist something useful too.

If you feel unsafe, or think about hurting yourself or someone else, call or text 988 (the Suicide & Crisis Lifeline in the US) or call 911.

What the cognitive triangle is (and what it isn't)

The cognitive triangle, also called the CBT triangle or the thoughts feelings behaviors triangle, puts three things at the corners of a triangle:

The arrows run in both directions. A thought shapes a feeling, the feeling shapes what the client does, and what they do feeds back into the thought. That loop is the point of the drawing: it shows a client how a problem keeps itself going, and that there is more than one place to interrupt it.

A situation sits outside the triangle and sets it off. Most worksheets, ours included, start there, so the client describes one specific moment rather than "my anxiety" in general.

It isn't Beck's cognitive triad. The names are close and they get mixed up in handouts and even in training. The cognitive triad is Aaron Beck's description of the thinking typical of depression: negative views of the self, the world and the future. A 2026 meta-analysis of 59 cross-sectional studies found a strong link between the triad and depressive symptoms (Huang et al., 2026). The triad describes what depressed thinking is about. The triangle describes how any thought connects to feelings and actions. You might use both with the same client: the triangle to map Tuesday night, the triad to name the theme that keeps showing up in the thought corner.

Where physical sensations fit: the five-part model

The triangle has no corner for the body, and for many clients the body is where the problem starts: the pounding heart in panic, the exhaustion in depression, the pain that comes before the worry. The five-part model fixes that.

Christine Padesky and Kathleen Mooney published it in 1990 as a "clinical tip" for presenting the cognitive model to clients. It has five parts: thoughts, moods, behavior and biology (physical reactions), all sitting inside the client's environment. In their words, "each of these four parts is connected to the others. They all sit inside our environment and interact with it as well" (Padesky and Mooney, 1990). Padesky's site notes that when the model was introduced in 1986 it was the first CBT model to highlight the role of environment. It is the main model in Mind Over Mood, the self-help workbook by Dennis Greenberger and Christine Padesky (1995; 2nd edition 2016).

Padesky later wrote that because the model includes life circumstances, it suits problems "triggered or complicated by environmental or sociocultural factors (e.g., discrimination, financial stress, chronic illness, sexual harassment, family violence)" (Padesky, 2020).

When to reach for the five-part model instead of the triangle:

Our worksheet keeps the triangle's three corners and adds a body line, so you can use it either way. If the situation is something hard and real, write it in section 1 and say so out loud: not every distressing thought is a distortion.

Where the CBT triangle comes from: Beck's cognitive model

Psychiatrist Aaron T. Beck developed cognitive therapy in the 1960s. In two papers titled "Thinking and Depression" (1963 and 1964), he described the distorted thinking he saw in depressed patients and set out a theory and therapy built on it (Beck, 1963; Beck, 1964). The Beck Institute sums up the cognitive model behind CBT as "the theory that the way individuals perceive a situation is more closely connected to their reaction than the situation itself" (Beck Institute).

The model has grown since. Beck himself described how it took in, in stages, "automatic thoughts, cognitive distortions, dysfunctional beliefs, and information-processing biases" (Beck, 2008). The triangle shows only the top layer, the automatic thoughts in one moment. The beliefs underneath belong in your case conceptualization; our case conceptualization examples show how a CBT lens links them to today's patterns.

The triangle drawing itself is a teaching shorthand for that model. We couldn't trace it to one original author. It appears in countless client handouts and in at least one well-tested treatment: in Trauma-Focused CBT, the therapist "helps children recognize connections among thoughts, feelings and behaviors (the 'cognitive triangle')" (Cohen and Mannarino, 2015).

What the evidence covers. The triangle is psychoeducation, one step inside CBT, and we found no study that tests it on its own. CBT as a whole is well studied. A review of 269 meta-analyses found the strongest support for CBT for anxiety disorders, somatoform disorders, bulimia, anger control problems and general stress, and judged the evidence base "very strong," while noting that at the time there were no meta-analyses for specific groups such as ethnic minority and low-income clients (Hofmann et al., 2012). So present the triangle as a way to understand the problem together, and measure whether the treatment it leads to is helping.

Three cognitive triangle examples

Each example is short, invented, and shows where you might step in. Real sessions are messier: clients give feelings as thoughts, skip corners and change the situation halfway through. That's normal in the first few tries.

Example 1: adult anxiety. Dana, 34, an accountant (invented).

Example 2: teen anger. Jalen, 15 (invented).

With teens, build the reframe around what the teen wants (here, the phone back on weekends), not what the parent wants. And if anger comes with hitting, breaking things or threats, or the conflict at home sounds unsafe, assess that before working on thoughts.

Example 3: depression. Ruth, 61, a retired teacher (invented).

Check risk before the reframe. "Nobody wants me" and "I'm a burden" match the two states the interpersonal theory of suicide links to suicidal desire: thwarted belongingness and perceived burdensomeness (Van Orden et al., 2010). When a client says either one, ask directly about thoughts of death and suicide, and document what you asked and what they said. Our DAP notes examples include a risk note written in full.

How to teach the cognitive triangle in a first CBT session

Padesky and Mooney found it "quite helpful in the first or second session" to present the model using what the client told you at intake, with Socratic questions rather than a lecture. The steps below take about 10 to 15 minutes.

A short script you can adapt:

Adapting the cognitive triangle for children and teens

TF-CBT, which serves children and teens aged 3 to 18 (NCTSN), gives a useful order of work. The therapist teaches the triangle using everyday events first and does not work on trauma-related thoughts at that stage, "since it is more effective to process these during the trauma narrative component." The therapist also "meets with the parent to introduce the cognitive triangle" and works on the parent's own unhelpful thoughts (Cohen and Mannarino, 2015). That order makes sense outside trauma work too.

For younger children:

For teens:

TF-CBT's developers describe further techniques for this work, including Socratic questioning, the responsibility pie and best-friend role play. If you work with trauma, train in a structured model rather than improvising the trauma stage.

Common mistakes with the cognitive triangle

How to write the cognitive triangle in a progress note

Name the intervention, say what the client produced, and record the response and the plan. "Did CBT" tells a reader little. "Introduced the cognitive model using the cognitive triangle with the client's own example; client identified the automatic thought and rated belief at 85%" tells them a lot.

What to record:

Keep the detail to what the note needs. You don't have to copy the whole worksheet into the note. If you keep the client's completed worksheet, treat it as part of the clinical record and follow your setting's records policy.

An example in DAP format, for Dana's second session (invented):

In SOAP, the client's account of the situation and thought goes in Subjective, your observations and ratings in Objective, the formulation in Assessment and the homework in Plan; see our SOAP note examples. In BIRP, teaching the triangle is the Intervention and what the client identified is the Response; the BIRP note examples show one session written in three formats. For wording, the progress notes cheat sheet lists CBT intervention words (cognitive restructuring, thought record, behavioral experiment) and client response words. For the GAD-7 and PHQ-9, our GAD-7 scoring calculator and PHQ-9 scoring calculator give the total and severity band.

How this works in TranqBay

TranqBay is practice software for therapists in private practice: a practice website, online booking, video sessions and session notes in one place. Here is where the cognitive triangle fits.

practice.tranqbay.health walks through a video session and the note on its session page. Its sample note is a DAP note that reviews a client's thought record, which is where the cognitive triangle usually leads.

Frequently asked questions about the cognitive triangle

Before your next session

Print the worksheet, try the first half with one client using a small moment from their week, and ask whether the triangle fits their experience. If it does, you have a shared map for the next stage of CBT. If it doesn't, ask what's missing: often it's the body or the client's circumstances, which is where the five-part model helps.

If you want booking, video sessions and session notes in one place, see how TranqBay works for private practice: you can look at a practice website design and the booking page your clients would use. If you're deciding whether to join, this page explains how joining TranqBay works.
