A meta-analysis[m1]  of Efficacy of Neurofeedback Treatment on Depression Disorder Abstract: Objective: Meta-analysis defines the rate of effect size of interventions by integrating the obtained results from different studies. The aim of the current meta-analysis was to determine the effectiveness of neurofeedback treatment in depression disorder. Methods: Totally 10 studies from 15 studies with accepted methodology were selected and meta-analysis was done on them. The data were gathered and the effect size of each study was calculated. Results: The combined effect size of all indicators was found to be significant according to cohen’s table which means high effect size. The combined effect size for depression is ES=0/60 (P=0/0179), for negative thought is ES=0/407 (P=0/0559), for the rate of alpha is ES=0/701 (P=0/0122), for the ratio beta/alpha is ES=0/512 (P=0/1635) and total effect size is 0/538. Conclusion: Based on the results of this meta-analysis, neurofeedback treatment based on the interpretation of Cohen’s effect size has large effect on reducing depression symptoms and normalizing the brain waves in depression disorders.
