  • Proven effectivenessCBT has the highest level of evidence for:

Cognitive-behavioral therapy (CBT) is based on a simple principle: our thoughts influence our emotions, which influence our behaviors. By modifying dysfunctional thought patterns, we can act on the vicious circle.

Fundamental principles

  • Collaboration: the therapist and patient work together, on an equal footing
  • Problem-oriented: focus on current difficulties, not distant past
  • Exercises between sessions: CBT involves active patient work
  • Limited duration: generally 12 to 20 sessions

Techniques used

  • Cognitive restructuring: identifying and questioning negative automatic thoughts
  • Progressive exposure: gradually confronting anxiety-provoking situations
  • Behavioral activation: resuming pleasant activities (used in depression)
  • Relaxation and mindfulness: stress management techniques

Proven effectiveness

CBT has the highest level of evidence for:

  • Anxiety disorders (generalized anxiety, phobias, panic disorder)
  • Mild to moderate depression
  • Obsessive-compulsive disorder (OCD)
  • Post-traumatic stress disorder (PTSD)
  • Chronic insomnia
  • Eating disorders

CBT is not a "surface" therapy. It durably modifies cognitive patterns when properly conducted.
