title: Commentary on the multimodal treatment study of children with ADHD.
abstract: The multimodal treatment study of attention deficit hyperactivity disorder (MTA Study) constitutes a landmark in the history of treatment research in child psychopathology, being the largest single study of its kind ever undertaken. Important findings have emerged from this project, as the papers in the present volume will attest. This commentary focuses on several concerns about the assumptions that appear to have guided the design of the MTA study, particularly its psychosocial treatment component, as well as the manner in which treatment results have been presented to date. In particular, no explicit theory of ADHD appears to have guided the construction of the treatment components, relying instead on implicit theories associated with those treatments, such as the notion that the symptoms of ADHD arise through faulty learning and defective contingencies of reinforcement. Future articles from this study will need to address these and other concerns if the results of the study are to be properly interpreted and the scientific and clinical yield is to be maximized.
