Participant Flow
Dates of recruitment: August 2008 to December 2009. Location: Nisonger Center, OSU Medical Center
Exclusion criteria: IQ \<80, mental age \<6, comorbid disorder or a medical disorder requiring medication that had psychoactive effects, \>5 previous NF treatments, antipsychotic medication within 6 mths pre-baseline, fluoxetine/atomoxetine 4-wks pre-baseline, stimulant 1-wk pre-baseline, or any other psychotropic medication 2-wks pre-baseline.
Participant milestones
| Measure |
Active Neurofeedback
In the active neurofeedback condition, subjects will receive accurate neurofeedback either twice weekly vs. three times a week, with the same amount of total treatment over 40 sessions, varying only in frequency.
|
Sham Neurofeedback
The sham condition will appear identical to the neurofeedback in all aspects: equipment, duration, frequency, and videogame choices. The only difference is that the interface module will be pre-programmed to give random feedback rather than contingent on the participant's brainwave power spectrum.

PRIMARY outcome
Timeframe: 40th treatment sessions ~ 13-20 weeksPopulation: Number randomized was denominator for percentage of participants completing 40 treatment sessions.

PRIMARY outcome
Timeframe: 40 treatment sessions ~ 13-20 weeksPopulation: Number of participants in active (n=24) and sham (n=10) neurofeedback completing 40 treatments.
The necessary duration of treatments was examined via identifying the number of treatments at which improvement stabilized, as shown visually on graphs of parent-rated ADHD symptoms from the SNAP-IV (0-3 scale, lower score is better) for those participants in the Active Neurofeedback who completed 40 treatment sessions.The Sham group is not included in this outcome.
