Cognitive Behavioral Therapy (CBT): A Complete Guide

Stacey Callahan, President of the French Association for Cognitive and Behavioral Therapies (AFTCC), is a clinical psychologist and a renowned professor of psychopathology. Her choice to dedicate her career to CBT—an approach that has strongly inspired teale—sparked our interest. Why did this method convince her over the years?

Let’s take a closer look at CBT, its purpose, and its value, through the lens of Stacey Callahan’s practice.

What Is Cognitive Behavioral Therapy (CBT)?

While traditional psychoanalysis, based on exploring developmental stages from childhood to adulthood, has clinical value, its effectiveness is not always systematic.

As Stacey points out:

‍“We cannot clearly establish how each individual moves from one stage to another, and traditional analysis can lack the scientific and empirical foundation needed to understand the whole person.”

To address this empirical need, Cognitive Behavioral Therapy (CBT) was developed, drawing on the early foundations of psychoanalysis. Stacey reminds us: psychology became a truly scientific discipline thanks to CBT.

As she explains:

‍“CBT looks at a person’s past to understand the learning processes that created maladaptive responses. Identifying and changing these patterns helps restore healthier mental functioning.”

How Does CBT Work?

The CBT process focuses directly on behavior—understanding it without judgment while respecting each individual’s uniqueness. Its aim is to identify and modify the thoughts and behaviors underlying difficulties such as phobias, addictions, or workplace anxiety.

As Stacey explains:

‍“CBT breaks down every level of a behavior—feelings, emotions, beliefs, and the behavior itself—to help develop a new response to the same situation.”

Unlike the classic image of psychoanalysis (the patient on a couch, the therapist listening silently), CBT is based on active exchange and collaboration.

As Stacey emphasizes:

‍“We’ve moved away from the ‘all-silence’ approach. In CBT, it’s a collaboration with the patient. I’m an expert in psychology, yes—but I’m not an expert in the patient’s life. Solving the problem means working together, combining both perspectives.”

Common CBT Techniques

Several well-established CBT methods are used in therapy, including:

• Cognitive restructuring: identifying and challenging automatic negative or irrational thoughts, then replacing them with more realistic, adaptive ones.
• Exposure therapy: gradually confronting anxiety-inducing situations or stimuli to reduce emotional reactivity and build coping strategies.
• Relaxation techniques: practices such as deep breathing, progressive muscle relaxation, or mindfulness to reduce stress and anxiety.

CBT is rarely limited to sessions alone: patients are often given homework exercises or journaling tasks to track thoughts, emotions, and behaviors.

As Stacey notes:

‍“CBT helps uncover exactly what triggered a reaction and how to undo it. The patient creates their own breakthrough—that’s what I love most. The therapist may guide the process, but the patient builds the change.”

What Are the Applications of CBT?

CBT can address a wide variety of issues. In the context of work and mental health, CBT is particularly effective in treating:

• Work-related stress, both acute and chronic
• Generalized anxiety disorders
• Depression and burnout
• Sleep disorders
• Substance use disorders and addictions

This makes CBT a powerful tool for workplace well-being strategies and for managing the consequences of psychosocial risks.

How to Put CBT into Practice?

The first step is to find a specialist—a clinical psychologist, psychiatrist, or neuropsychologist. After an initial assessment to identify problems and patterns, therapist and patient set clear goals for the therapy.

Sessions, whether in person or online, are complemented by personal exercises designed to help patients gain self-awareness and change behavior.

Today, thanks to digital tools, it is even possible to extend therapy and practice CBT techniques without direct supervision—making it an accessible complementary tool for improving mental health at work.

As Stacey explains:

‍“Technology is great for helping people recognize their thoughts. It’s accessible, fast, and simple to use. It enhances therapy, making results more tangible and long-lasting.”

CBT and teale: Making Mental Health Accessible

When asked about teale’s approach, Stacey shared her perspective:

‍“CBT is an excellent entry point for people experiencing difficulties but who don’t feel ready—or don’t dare—to see a therapist. Its adaptability explains why it’s so widely used in workplace settings. The approach taken by teale, inspired by CBT, is particularly well-suited: it doesn’t overwhelm the individual—they remain in control of their own progress. For organizations, the app is a clear added value: it makes well-being accessible to everyone, quickly. Employees feel better, which directly impacts both the quality of their work and company performance.”
