Behavioral and Cognitive Therapies (CBT) are the application of scientific psychology :

It is an approach described as psychotherapy that focuses on changing problematic thoughts and behaviors. CBT aims to explain the dysfunctions of the individual in order to cure them. The approach applies principles derived from scientific research to treat and modify certain human behaviors. CBT is an approach that focuses first on solving current problems and only secondly on understanding their origin in the past. A good therapeutic relationship is considered essential to an effective cognitive-behavioral psychotherapy. Finally, CBT can be described as generally active, directive, structured and relatively short-term.

The person seeing a cognitive-behavioural therapist (CBT) will learn to analyze his or her problem, here and now, while taking into account its historical causes.
Cognitive behavioral therapy can be applied in many cases:

Anxiety, anxiety and panic attacks
Phobias (agoraphobia, social phobia, animal phobias…)
Obsessive-compulsive disorders
Depression
Insomnia
Eating disorders
Difficulties in asserting oneself
Positioning in a group
Stress management
Burn-out
Eating Disorders

Is CBT therapy really effective?

The results of several controlled studies confirm that cognitive-behavioral therapy is effective in treating anxiety disorders. It is the most effective psychological treatment for moderate and severe depression. It is as effective as antidepressants for many types of depression and related problems such as sleep disorders, addictions, and eating disorders.
The French Association of Behavioral and Cognitive Therapy also reports that cognitive behavioral therapy has been found to be effective even in the treatment of schizophrenia and pervasive developmental disorders.

Techniques used in cognitive behavioral therapy

The CBT therapist will make extensive use of the technique of confronting dysfunctional thoughts, used in cognitive restructuring. This technique consists mainly of the person confronting his or her anxiety by exposing him or herself to mental images, objects and/or situations that generate fear until it diminishes.
Other cognitive-behavioural intervention strategies can also be used, such as

-Psychoeducation

-Cognitive restructuring or correction (a methodology that promotes awareness of the links between thoughts and emotional and/or physiological states)

-Problem solving

-Role playing

-Diaphragmatic breathing (or respiratory rehabilitation)

-Social skills training
