To the Editor: Van Dongen-Boomsma et al assessed the efficacy of electroencephalographic (EEG) neurofeedback in children with attention-deficit/hyperactivity disorder by comparing an experimental group (n = 22) receiving EEG neurofeedback to a placebo group (inactive neurofeedback) (n = 19). Results did not show significant differences between the 2 groups. The authors report that, post hoc, the “sample had 80% power to detect a treatment effect of 0.90” and that “it is unlikely that the negative results were due to limited statistical power,” concluding that their study sheds serious doubt on the effectiveness of EEG neurofeedback as a way of treating children with attention-deficit/hyperactivity disorder.
