Cognitive behavioral therapy (CBT) is an evidence-based psychological treatment that was developed through decades of scientific research. There is a growing body of studies that show that CBT is an effective treatment for a variety of conditions including depression and anxiety. For most mood and anxiety problems, CBT is at least as effective as medication. Over the long term, CBT is often more effective than medication in maintaining wellness and reducing the risk for relapse. Many people may benefit from a combination of medication and CBT. Often, medication is used to provide some relief from symptoms and CBT is used to provide long-term strategies for getting well and staying well.
