The core of cognitive behavioral therapy is the impact of a person’s thoughts on their emotions and behavior. Adjusting your thoughts, as a result, can help improve negative feelings and actions that might be causing distress to a client. The cognitive triangle worksheet clearly illustrates this relationship and helps clients understand why addressing their negative thoughts can improve their entire well-being.
Below, learn more about how you can use a CBT triangle worksheet to help support your clients’ mental health, with guidance from fellow CBT therapists.
What is the cognitive triangle?
Also called the cognitive triad or CBT triangle, the cognitive triangle illustrates the relationship between your thoughts, emotions, and behaviors. The principle helps clients understand that when they change their negative thoughts, they can also make positive adjustments to their emotions and behaviors.
What types of clients benefit from using a cognitive triangle worksheet?
The cognitive triangle is the foundation for all CBT work you do with clients, so any client who can benefit from cognitive behavioral therapy will also benefit from a cognitive triangle principle and worksheet.
“The CBT triangle can help anyone who wants to find more balance in their thoughts, such as people who struggle with anxiety, depression, or other mood disorders,” says Natalia Tague, a private practice therapist in Virginia.

How to use a cognitive triangle worksheet in CBT with your clients
Whether you leverage a simple illustration, or something more interactive, there are many ways to use the CBT triangle in your therapy.
Incorporate it into an assessment
If CBT is your primary treatment modality, consider introducing the CBT triangle during your initial assessment or the very first session.
Mike Arevalo, PsyD, a private practice therapist and Headway’s clinical product lead, says he uses the CBT triangle to introduce his theoretical orientation to clients, which may help them determine whether he’s the right fit or demystify the process of therapy when clients are nervous. “I always explain it at the very beginning to help people understand what techniques I’ll be using in therapy,” he says.
Offer psychoeducation
Once you start doing therapy work with a new client, the cognitive triangle can provide a helpful framework. Amanda Reagan, a private practice therapist and Headway’s clinical quality lead, uses the cognitive triangle as a foundation for client treatment plans and for setting goals with clients.
“It allows folks to see how those arrows are moving in the same direction, which is an important tie-in when we’re defining goals,” she says.
Tague typically introduces the cognitive triangle as a way to develop a shared language before moving forward with treatment For example, it’s common for people to confuse thoughts and feelings, which can be a barrier to treatment. The illustration can help clients understand the difference between these two before you introduce the thought record and cognitive distortions and restructuring.
“It’s a great way to start separating out thoughts, emotions, and behaviors with clients,” she says, and it introduces clients to an avenue into challenging and reframing the thoughts that negatively impact their emotions and behaviors, which will come later in treatment.
Make it interactive
It’s easy to find illustrations of the cognitive triangle, but it may be helpful to create an interactive experience in session.
Anita Owusu, a Toronto-based private practice therapist, explains the triangle and asks adult clients to draw it out. Or, she puts pieces of paper on the ground labeled “thoughts,” “feelings,” and “behaviors” and then has the client walk around the triangle as they talk about an experience. She also sometimes has clients draw two triangles, one representing a current situation and one representing how they can change it to be less distressing.
“It’s a good way to get people more engaged,” she says.
