The Famous CBT Triangle: With Examples and Worksheets

Updated: Nov 9

The cognitive triangle connects thoughts, feelings, and behaviors. Learn how.

This infographic shows how the CBT triangle is typically depicted, with thoughts, feelings, and behaviors at each of the three points.

Thinking negatively is a common human trait. We look for problems so we can be ready for them. We beat ourselves up because we don’t want to repeat the same patterns.

However, this tendency to think negatively typically does the opposite of helping. Instead, it makes us more likely to feel down about ourselves, and therefore less happy in general.

The CBT triangle, or cognitive triangle, is a tool used by therapists and others to teach the concept of changing negative patterns of thought. The points of the triangle show how thoughts, feelings, and behaviors are all connected. By changing one of these three points, you can change the others for the better.

I build on the concepts of the triangle with worksheets on changing thoughts, challenging trauma-related beliefs, and facing fears and worries. You can check out the bundle here.

Triangle Diagrams

While the triangle is drawn in different ways, it typically shows thoughts at the top, with feelings at the bottom right point, and behaviors on the left. The visuals included throughout the article depict the steps of using the tool. First, you can recognize the pattern that’s occurring and then start to change it. Details of that process are further outlined below.

This is an example of a thought pattern someone may work to change.

History of This Approach

The thought triangle is a simplified tool based on the ideas of cognitive behavioral therapy, or CBT. This particular therapy tool is incredibly popular, often used by therapists aiming to help people deal with all kinds of problems.

The original practice of CBT was developed by Dr. Aaron Beck and colleagues in the 1960s. Since then, the basic ideas have been adapted to treat multiple conditions including anxiety, depression, trauma responses, lack of confidence, eating disorders, physical illness and much more. Thousands of studies have validated this approach.

Since the tools of this therapy are so straightforward, many people find the practices are helpful even when learned outside of therapy. Self-learning CBT programs are also found to be effective, although in some cases a therapist is needed to help with more difficult thoughts. Many of the programs start with the basic CBT triangle to lead up to more complicated techniques.

This infographic provides an example of changing a negative thought using the cognitive triangle.
Replace your negative thought with a more neutral or positive one.

Using the Tool

Since changing thought patterns is the most common technique used, we’ll start there. Let’s take a look at this in practice.

Maria is an English teacher at a local high school. She used to enjoy acting in local productions, and really wants to try out for the local community play. The last two times she auditioned she got cut at the last call-back. Although the director encouraged her to come back next time, she started to doubt herself.

After this disappointment, Maria told herself that she must not be talented or attractive enough. While she still wants to be in the play, she is repeatedly telling herself she won’t be successful. She feels discouraged, so she decides not to go.

She uses this decision to beat herself up and again tell herself she’ll never be an actor. The cycle continues.

Here’s how this would fit into the CBT triangle diagram:

Thought: I am not good enough to be an actor

Feeling: Discouragement, self-doubt

Behavior: Not trying at all

Giving up may be a way for Maria to protect herself against more disappointment. And by not challenging her thoughts, she stays in this negative cycle.

Maria has come to a conclusion she doesn’t know to be true, and hasn’t considered any alternatives. In order to challenge the old way of thinking, she’ll need to consider new ideas about her situation. Here are some things we know about what’s going on, which could challenge her conclusion:

  • The director of the local theater was encouraging when she tried out before, although he didn’t pick her for any previous parts

  • Maria knew she would be a stretch for those parts in the past because she didn’t really fit the characters

  • The new play is much more suited to her strengths

  • Maria knows other good actors that don’t always get cast, depending on the play

  • Maria has only tried out a couple of times, and she knows most actors get turned down a lot before they get cast

  • In college, Maria got consistent feedback that she was a solid actor

Maria can consider all of this information as a whole. After some thought, and talking to a friend about it, Maria decides to consider a new thought.

New thought: I’ve had good feedback about my acting in the past. The director encouraged me to try out again.

New feeling: Excited, anticipation

New behavior: Preparing for the part and going to the audition

We don’t know for sure if Maria will get the part. It’s scary to put ourselves out there and try something new. But we also know if she stays in her negative pattern she’ll never know, and she’ll likely regret not trying.

Of course, using the CBT triangle isn’t a one-time process. Maria will likely have other self-defeating thoughts she’ll need to challenge as well. However, with practice Maria can actually start to change her pattern of actively discouraging her own dreams and goals.

Eventually, her brain won’t go automatically to the negative thought. She’ll become a more naturally positive thinker.

Even if acting isn’t in her future, this can lead Maria to find things she does enjoy which make her happy. Or, she could actually end up the star of the play! She decides it’s worth the risk.

The Thought Highway

Humans have thousands of thoughts per day -- perhaps in the range of around 6,000. That’s a busy brain.

Think of your brain as not just one consciousness, but multiple ones. We have the instinctual areas of the brain which randomly churn out ideas and thoughts. Then we have other parts of the brain that organize this information, make sense of it, filter it, and make decisions.

Rather than simply accepting each automatic thought as fact, we could choose to observe and release certain thoughts.

This idea is a psychological, sometimes spiritual, concept often used in therapies like CBT, DBT (dialectical behavioral therapy) and ACT (acceptance and commitment therapy). It’s also consistent with brain science.

We know certain parts of the brain act more on fear instinct, while other areas are more balanced and intentional. We need each of these functions to live a balanced life. However, we need them working together, rather than independently.

In recent years, scientists have found that those who are more anxious, and/or those with PTSD may have an interruption in communication between these different areas of the brain. While the instinctual, reactionary portion of the brain is awake and active, the area that processes and makes sense of this instinctual reaction may be cut off.

Researchers are hoping this new information will lead to medications to help get these networks in the brain working together again. In my experience, we already have a behavioral technique that gets this highway moving again. The technique is CBT.

This infographic has blank spaces with prompts to write down your new thought and the new feeling and behavior you expect.
Replace the old thought you want to change with a more balanced and helpful thought.

Combining the Three Points

When I work with people who have high anxiety, post-traumatic stress disorder (PTSD), or even depression, we work with each area of the triangle. Here’s how.

1. Validating Emotions

It does no good to dismiss, minimize, or ridicule our own feelings. While it’s common, it’s entirely unproductive, and unfair to ourselves. Feelings are a biological function, which most likely evolved to keep us safe.

When we are constantly told our feelings aren’t accurate, aren’t allowed, or are childish, we then form negative feelings about our feelings. (These even have a name -- they’re called meta emotions.) Even these feelings about our emotions are normal!

Counterintuitively, the best way to change an emotion is to accept it. Have you ever noticed that you felt better when someone finally “got” what you were saying, or how you felt about a situation? Simply feeling understood, which helps you validate your own feeling, can relax emotions.

Feelings are connected to the body. This seems particularly true for difficult feelings like fear, hurt, or disappointment. Next time you feel this way, notice how you know what you’re feeling. It’s most likely because your stomach is sinking, your body is shaking, or you feel a flutter in your chest.

Although feelings originate in the brain, we feel them in our body.

That’s because emotions are about protecting us. Your body alerts you that something is wrong. (Or in the case of positive feelings, that a situation is desirable.)

By learning to accept and validate your own feelings, you can create a better relationship with them. They will actually have less control over you, rather than more.

When I’m dealing with difficult feelings, or coaching clients about them, I look for a balance. This doesn’t mean feeling neutral, or even calm. It means giving yourself time to feel first, and then to work towards feeling better.

Even allowing yourself to have a tough feeling for a few minutes can be helpful. Try to relax into it, even if it’s painful, and accept it as is.

In some cases, you’ll already find relief through this acceptance. If you are still struggling after that, then you can return to your thoughts to look for a negative pattern. Your emotions may be persisting because your thoughts are keeping you stuck there.

2. Challenging Thoughts

Given we have thousands of thoughts per day, we can’t possibly moderate them all. Fortunately we don’t need to. However, we can zone in on the thoughts that are making our life more difficult.

These negative thought patterns tend to center around a theme. You’ll be quite familiar with them. Common ones are along these lines include:

  • I’m not good at a _______ (a certain thing)

  • There’s something wrong with me

  • I should be doing or feeling something that I’m not

  • I shouldn’t be doing or feeling something that I am

  • My life never goes well

  • People are against me

  • I don’t measure up to others

  • See? I told you this would happen

These thoughts can lead to very painful feelings that can make it difficult to function sometimes. However, consider this -- these thoughts are so common you just read it on a list written by a therapist.

That tells you how many other people must think the same way, at least some of the time. (In my experience it’s pretty much everyone.)

It also tells you that these thoughts may come from an inherent pattern in the human brain, and are quite often not based in fact. Perhaps they’re actually based on a confused instinct, or habit, and not in truth?

In CBT therapy, we take these thoughts one at a time and begin to challenge them. Over time, it becomes more natural to do so. The brain essentially reprograms how it naturally thinks. It’s pretty incredible.

By practicing your new thought regularly you can change how you feel and react.
