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: 2 years

Population: Based on inclusion \& exclusion criteria and randomization in a 2:1 ratio to active NF vs. sham NF.

The feasibility of the double-blind, sham-controlled design was examined in 3 ways, this first way was via the number of participants recruited.

PRIMARY outcome

Timeframe: 40th treatment sessions ~ 13-20 weeks

Population: Number randomized was denominator for percentage of participants completing 40 treatment sessions.

The feasibility of the double-blind, sham-controlled design was examined in 3 ways. The second way was via the percentage of participants retained the end of treatment (40th session).

PRIMARY outcome

Timeframe: Post-treatment at session 40

Population: Participants in both Active and Sham Neurofeedback completing 40 treatment sessions.

The feasibility of the double-blind, sham-controlled design was examined in 3 ways. The 3rd way was the percentage of child and parent post-hoc guess regarding treatment assignment.

PRIMARY outcome

Timeframe: 24 treatments ~ 8-12 weeks

Population: Those completing 24 treatments

Parent \& child satisfaction of treatment frequency (x2 vs x3 treatments per week) was measured on a likert scale with anchors 0 (indicating low satisfaction) and 7 (indicating high satisfaction).

PRIMARY outcome

Timeframe: 40 treatment sessions ~ 13-20 weeks

Population: 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.
