INTRODUCTION — CBT, a Therapy You Practice

There is a persistent misconception that therapy essentially involves lying on a couch and talking about one's childhood for years. This vision, inherited from classical psychoanalysis, has shaped the collective imagination to such an extent that many people hesitate to seek help, convinced that they will have to explore every corner of their past before experiencing any relief.

Cognitive and behavioral therapies — CBT — offer a radically different approach. Not opposed to exploring the past, but resolutely focused on the present and on action. Their founding principle is strikingly elegant: it is not events themselves that generate our suffering, but the interpretation we make of them. Change the interpretation, and you change the emotion. Change the emotion, and you change the behavior. Change the behavior, and you change your life.

What Is CBT?

Cognitive behavioral therapy is a structured, scientifically validated psychotherapeutic approach based on identifying and modifying dysfunctional thoughts and maladaptive behaviors. It was developed in the 1960s by Aaron T. Beck for the treatment of depression, and subsequently extended to a considerable number of disorders: anxiety, phobias, obsessive-compulsive disorder, eating disorders, addictions, chronic pain, insomnia, and many others.

What distinguishes CBT from other therapeutic approaches is its empirical and practical nature. Each session is built around concrete objectives. The therapist and the patient work together — this is called the therapeutic alliance — to identify the mechanisms that maintain suffering and implement strategies for change. Between sessions, the patient carries out exercises, behavioral experiments, and observations. Therapy is not confined to the office: it is lived every day.

The scientific evidence supporting the effectiveness of CBT is considerable. A landmark meta-analysis covering 409 clinical trials and 52,702 patients demonstrated its significant effectiveness in treating multiple psychological disorders (Cuijpers et al., 2023, PMC9840507). This evidence base makes it one of the best-validated psychotherapeutic approaches in the world.

Why This Book?

This book was born from a simple observation I make every day in my practice as a cognitive-behavioral psychotherapist: the clients who progress the fastest are those who practice between sessions. CBT is not a passive therapy. It is mental training, comparable to physical training. You can read every book on running — you will not run any faster until you put on your shoes and run that first mile.

This practical guide was designed as a true exercise companion. Each chapter contains concrete tools, worksheets to complete, and exercises to practice. It does not replace therapeutic follow-up — we will return to this in the conclusion — but it can serve as a valuable complement to ongoing therapy, or a first step for those who wish to understand and experience the mechanisms of cognitive and behavioral change.

How to Use This Book

I recommend reading this book in order, as each chapter builds upon concepts introduced in the previous ones. The first two chapters lay the theoretical foundations. Chapters 3 and 4 take you deeper into understanding your thought patterns. Chapters 5 and 6 introduce behavioral techniques. Chapter 7 opens the door to third-wave approaches. Finally, Chapter 8 guides you in building your own personal therapy plan.

For each chapter, you will find:

Get yourself a dedicated notebook — your "CBT notebook." You will use it to record your observations, your exercises, your discoveries. This notebook will gradually become your most valuable tool: a living map of your psychological functioning and your evolution.

One last piece of advice before you begin: be patient with yourself. The thought patterns you are about to discover were built over years, sometimes decades. They will not transform overnight. But every exercise completed, every thought identified, every distortion spotted is a victory. And these small victories, put together, build deep and lasting change.

Happy reading, and above all, happy practicing.

CHAPTER 1 — The Foundations of CBT

"It is not things that disturb us, but the judgments we form about things."

— Epictetus, Enchiridion

Epictetus's words, written nearly two thousand years ago, contain the seed of the fundamental insight that would give rise, twenty centuries later, to cognitive and behavioral therapies. The idea that our suffering is not the direct product of the events we experience, but of the way we interpret them, forms the bedrock upon which the entire edifice of CBT rests.

This first chapter invites you to understand the historical and theoretical foundations of this approach. We will see how two pioneers — Aaron Beck and Albert Ellis — revolutionized psychotherapy by placing thought at the center of the therapeutic process. We will then explore the cognitive model that structures the entire CBT approach, and you will complete your first two practical exercises.

Aaron Beck and the Cognitive Model

Aaron Temkin Beck (1921–2021) is considered the founding father of cognitive therapy. An American psychiatrist trained in psychoanalysis, he progressively challenged psychoanalytic models of depression during the 1960s. Where psychoanalysis saw depression as hostility turned against the self, Beck observed in his depressed patients a constant stream of negative automatic thoughts — spontaneous, rapid thoughts, often barely conscious, that colored their perception of the world with a uniformly dark hue.

Beck identified what he called the negative cognitive triad: a negative view of the self ("I'm worthless"), a negative view of the world ("everything is hostile"), and a negative view of the future ("nothing will ever get better"). These three components, feeding off each other, create a closed cognitive system that is self-sustaining and self-reinforcing.

Beck's genius was in showing that these negative thoughts are not merely symptoms of depression — they are an active driver of it. And above all, they can be identified, questioned, and modified. This discovery paved the way for a therapy based on cognitive restructuring: teaching the patient to spot automatic thoughts, evaluate their validity, and replace them with more realistic and adaptive thoughts.

Beck's cognitive model is organized around three levels of cognition:

Automatic thoughts are thoughts that arise spontaneously in our mind in response to everyday events. They are rapid, often below the threshold of consciousness, and we generally take them for absolute truths without ever questioning them. Examples: "I'm going to fail," "He doesn't love me anymore," "It's my fault."

Intermediate beliefs are rules, attitudes, and assumptions that organize the way we think. They often take the form of "if... then..." or "I must..." Examples: "If I'm not perfect, nobody will love me," "I must always be available for others."

Cognitive schemas (or core beliefs) are the deepest structures, forged during childhood, that constitute the foundation of our cognitive identity. They are absolute, rigid, and global. Examples: "I am fundamentally inadequate," "The world is dangerous." We will explore them in detail in Chapter 3 with Young's early maladaptive schemas.

The Cognitive Model in Everyday Life: Concrete Examples

To fully grasp the power of Beck's cognitive model, let us observe how it unfolds in situations we all experience every day, often without being aware of it.

At work. You send an important email to your supervisor and receive no response that day. At the level of automatic thoughts, your mind instantly generates: "He didn't like my proposal. He must regret giving me this project." At the level of intermediate beliefs, an implicit rule activates: "If someone doesn't respond quickly, it means my work is worthless." At the level of the deep schema, the core belief resonates faintly: "I'm not good enough." Emotional result: anxiety, doubt, rumination. Behavioral result: you spend the evening mentally rewriting the email, you sleep poorly, and the next morning, you discover that your supervisor was simply traveling and hadn't checked his emails.

In the family. Your teenager answers you curtly when you ask how their day went. Automatic thought: "They don't respect me anymore. I've failed as a parent." Intermediate belief: "A good parent knows how to maintain open dialogue with their children." Deep schema: "I'm incapable of creating solid bonds." In reality, your teenager is going through a perfectly normal developmental phase, documented by decades of developmental psychology research (Steinberg, 2001). Their curtness has nothing to do with your parenting skills.

In a relationship. Your partner forgets the anniversary of when you first met. Automatic thought: "Our relationship doesn't matter to them." Intermediate belief: "If someone truly loves me, they remember all the important dates." Deep schema: "I'm not important enough to be loved." Beck (1976) showed that these automatic interpretations are so rapid that they seem to be direct perceptions of reality, when in fact they are mental constructions — filtered by our beliefs, distorted by our history, amplified by our current emotions.

One of the most revealing exercises I suggest to my clients is to note, for a single day, all the micro-interpretations they make of ordinary events: a colleague who doesn't say hello, a red light that lasts too long, a queue at the supermarket. Most are astonished to discover the considerable volume of automatic judgments their mind produces relentlessly — and above all, the systematically negative tone of these judgments. This awareness often constitutes the first true therapeutic breakthrough.
