A 2005 study showed that adults who added cognitive behavior therapy to their treatment regimen reported a decrease in severity of symptoms, depression, and overall anxiety than those who stuck to a purely pharmacological treatment, as well as better response to treatment. A similar study conducted in 2010 reported reduced ADHD symptoms and improved treatment response as well, both during treatment process and in post-treatment follow-ups months later. Additional research found that groups of adults undergoing cognitive behavioral therapy showed greater improvement in terms of self-esteem and understanding of the disorder than control groups did.
Cognitive behavioral therapy can also be combined with anger management training to help children who display increased aggression as part of their ADHD symptoms. Research has shown that while cognitive behavioral therapy alone can improve ADHD symptoms for both aggressive and nonaggressive children, the addition of anger management sessions can lead to even greater improvement.
