Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that affects millions of children and adolescents worldwide. The treatment of ADHD has long been a subject of research and debate, with various approaches available.
A pivotal development in ADHD research was the establishment of the Multimodal Treatment Study of ADHD (MTA) in the late 1990ties by the US Federal Government. The results of this study, published in December 1999, stands as the largest research undertaking on ADHD in children.
The MTA study’s long-term tracking of participants into adolescence was crucial in understanding the evolving nature of ADHD and its comorbidities. The studies ongoing follow-up reports offer valuable insights into the trajectory of ADHD throughout the childhood and adolescence, paving the way for more comprehensive and effective interventions.
Moreover, the MTA study highlights the significance of addressing non-ADHD symptoms that frequently accompany the disorder, such as anxiety, depression, social skills deficits, and academic challenges.

Design of Multimodal Treatment Study (MTA) for ADHD
The MTA study involved 579 elementary school-aged boys and girls diagnosed with ADHD.
These children were divided into four different treatment groups to assess the effectiveness of various approaches.
- The first group received medication tailored to each child’s specific needs.
- The second group underwent intensive behaviour management, which included summer camp program, ongoing support for teachers, parent training and individual and group therapy.
- The third group combined medication with behaviour management.
- The fourth group received comprehensive assessments and referrals to community-based resources.
Results of MTA Study
After a 14-month study period, the data has been evaluated. The first and third group that received medication showed remarkable progress, achieving significant improvements. Interestingly, adding the behavioral psychotherapy component did not substantially enhance outcomes, except in cases where individuals had co-existing conditions like anxiety or depression. In those cases, the combination of medication (preferably antidepressants) and behavioral psychotherapy made a notable difference.
Surprisingly, the intensive behavioral psychotherapy program, despite its considerable time and resource investment, proved less effective than medication alone.
The most disappointing finding was that the benefits of the psychotherapy program did not endure after the treatment ended. The hope had been that these techniques would become internalized by the children, allowing reducing the need of intensive treatment. Unfortunately, once the treatment ceased, so did the benefits, indicating the need for ongoing support and management.
Multimodal Treatment Study. Conclusion
Over the past two decades, there have been significant advancements in understanding and treating ADHD. In this context, medication remains the main pillar of ADHD treatment in children and adolescents. However, it’s important to understand that medication is not a magical tool solving all problems caused by ADHD. It’s more a gateway, enabling individuals with ADHD to engage in the necessary work that they need to do.
A closer examination of the data reveals that children in the combined treatment group, receiving both behavioural psychotherapy (preferably CBT) and medication, exhibited similar levels of improvement with lower medication doses. This suggests that a combined approach may offer advantages in terms of optimizing medication dosage and potentially reducing side effects.
Another crucial aspect to consider is the variability in outcomes within medication management programs. The study demonstrates that not all medication treatments yield identical results. It emphasis on regular follow-up and adjustments of the medication tailoring the pharmacotherapy to individual needs, rather than adopting a one-size-fits-all approach.
