Abstract
Objective:
To review the primary and secondary findings from the Multimodal Treatment study of ADHD
(MTA) published over the past decade as three sets of articles.
Method:
In a two-part article—Part I: Executive Summary (without distracting details) and Part II:
Supporting Details (with additional background and detail required by the complexity of the MTA)—we
address confusion and controversy about the findings.
Results:
We discuss the basic features of the gold standard used to produce scientific evidence, the
randomized clinical trial, for which was used to contrast four treatment conditions: medication management
alone (MedMgt), behavior therapy alone (Beh), the combination of these two (Comb), and a community
comparison of treatment “as usual” (CC). For each of the three assessment points we review three areas
that we believe are important for appreciation of the findings: definition of evidence from the MTA,
interpretation of the serial presentations of findings at each assessment point with a different definition of
long-term, and qualification of the interim conclusions about long-term effects of treatments for ADHD.
Conclusion:
We discuss the possible clinical relevance of the MTA and present some practical suggestions
based on current knowledge and uncertainties facing families, clinicians, and investigators regarding the
long-term use of stimulant medication and behavioral therapy in the treatment of children with ADHD. (J.
