Cognitive behavioral therapy (CBT) is an effective treatment for anxiety disorders like generalized anxiety disorder (GAD), post-traumatic stress disorder (PTSD), and obsessive-compulsive disorder (OCD). CBT is based on the idea that thoughts, emotions, and behaviors are all connected, and that dysfunctional or negative thinking can contribute to anxiety. CBT uses techniques like cognitive restructuring to help people identify and modify distorted thoughts and beliefs. Homework is also assigned between sessions to apply CBT skills in daily life.
