The Multimodal Treatment Study for Children with Attention-Deficit/
Hyperactivity Disorder (MTA Study)
Principal Investigator: Professor Stephen Hinshaw
Funded by the National Institute of Mental Health, the MTA Study (Multimodal Treatment Study for Children with Attention-Deficit/Hyperactivity Disorder) is a multi-site treatment project dedicated to identifying the most effective treatment regimen for children with ADHD. In 1995 and 1996, participating families were randomly assigned to one of four 14-month-long treatment conditions: medication management, intensive behavioral management, a combination of the aforementioned treatments, or assessment and referral to community providers. As a longitudinal study, the MTA conducts follow-up assessments on a biannual basis. It presently is in its 14-year follow-up and the assessments are now conducted with the young adults and their families (150 families total), at the Berkeley site (900 overall across the six sites). This is the largest clinical trial for children ever funded by the National Institute of Mental Health. The National Institute on Drug Abuse now funds the young-adult follow-up phases.
