Cognitive Behaviour Therapy (CBT) is a form of psychotherapy that aims to change people's attitudes and behaviors by understanding their thoughts, images, beliefs, and attitudes. CBT works by identifying negative thought patterns and helping individuals develop strategies to tackle emotional problems. The therapy typically takes 3-6 months, with weekly sessions lasting 50 minutes or an hour. CBT combines cognitive therapy, which looks at how our thoughts create feelings and mood, and behavioral therapy, which focuses on the relationship between problems, behavior, and thoughts.
