Study Description: This study will determine the impact of a 1 month exercise intervention on the symptoms of 7-11 year-old children with ADHD. This exercise program could be helpful to children with behavior problems. We will also try out a way to encourage children to keep their heads very still for several minutes, by utilizing an MRI replica, the PiTracker, that shows them when they move. This will help children in future studies to provide very good brain images to show how exercise affects brain health.
Principal Investigator: Catherine Davis
Eligibility Criteria: Inclusion Criteria for the Exercise Study 7-11 years of age ADHD Diagnosis: predominantly Hyperactive-Impulsive Type or Combined type. This will be determined using the following criteria: 6 or more symptoms in more than one setting endorsed ?pretty much? or ?very much? by parent and teacher on the Hyperactive/Impulsive scale of the Disruptive Behavior Disorders (DBD) Rating Scale 2 or more domains endorsed at 3 or higher on a scale of 0 to 6 on the Impairment Rating Scale (IRS) diagnosis confirmed by clinical interview Exclusion Criteria for the Exercise Study any medical condition which contraindicates or would interfere with participation in testing or vigorous exercise (e.g., orthopedic conditions) any medications that would interfere with research measurements (e.g. antipsychotics, stimulants, sedating antihistamines, seizure medications) participation in any formal exercise program that meets more than 1 day/week (other than physical education) current treatment for ADHD, or having a sibling enrolled in the study. We may allow siblings to attend the program together to accommodate family needs, as capacity permits, but the sibling of an enrolled subject will not be provided with incentives or included in analysis. With Dr. Mabe?s approval, we will ask families of children diagnosed with ADHD during the study to wait until after posttest to begin any pharmaceutical or psychosocial treatment. Inclusion Criteria for the PiTracker Study 7-11 years of age Exclusion Criteria for the PiTracker Study None
Compensation: Yes, subjects will be compensated.
Compensation Explanation: For the Exercise Study, incentives will be provided to parents in the amount of $5 for completing the Disruptive Behavior Disorder Rating Scale, the Impairment Rating Scale, and the Strength & Difficulties Questionnaire (approximately 30 minutes to complete these 3 surveys) prior to a clinical interview. Parents will earn $10 for completing the same 3 surveys at posttest. Up to 50 children may be included in the Exercise Study and will earn $5 for completing baseline measurements and $10 for providing posttest measurements. In the exercise intervention, children will receive incentives/weekly prizes (e.g. pencils, stickers, small toys; value of <$1 per item). Like parents, the child?s teacher will earn $5 for completing surveys at baseline and $10 at posttest. Schools that participate in the data collection process will receive $25 worth of school supplies. These payments will be in the form of either giftcards for subjects or school supplies for teachers. For the PiTracker Study, up to 50 children may be included and will earn prizes (e.g. pencils, stickers, small toys) up to $5 worth for each visit, up to 5 visits.
