Neurofeedback Against Binge Eating: A Randomized Controlled Trial in a Female Subclinical Threshold Sample
European Eating Disorders Review

Abstract
Brain‐directed treatment techniques, such as neurofeedback, have recently been proposed as adjuncts in the treatment of eating disorders to improve therapeutic outcomes. In line with this recommendation, a cue exposure EEG‐neurofeedback protocol was developed. The present study aimed at the evaluation of the specific efficacy of neurofeedback to reduce subjective binge eating in a female subthreshold sample. A total of 75 subjects were randomized to EEG‐neurofeedback, mental imagery with a comparable treatment set‐up or a waitlist group. At post‐treatment, only EEG‐neurofeedback led to a reduced frequency of binge eating (p = .015, g = 0.65). The effects remained stable to a 3‐month follow‐up. EEG‐neurofeedback further showed particular beneficial effects on perceived stress and dietary self‐efficacy. Differences in outcomes did not arise from divergent treatment expectations. Because EEG‐neurofeedback showed a specific efficacy, it may be a promising brain‐directed approach that should be tested as a treatment adjunct in clinical groups with binge eating.
