CBT is the most extensively scientifically tested, evidence-based psychological approach.

CBT became the first talking therapy demonstrated to be more effective than medication for the treatment of depression in 1977. In 1981, a UK-based research group published the results of a second study with the same findings.

Since then, more than 2000 studies have demonstrated the efficacy of CBT for psychiatric disorders, neurodiverse conditions like ADHD and the autism spectrum conditions, psychological problems and as an effective intervention for medical problems with a psychiatric component. CBT, implemented correctly, helps individuals get better and stay better.
