- Fulfilled DSM-IV criteria for depressive disorders.
- Persons who had organic disorders were excluded.
- Who had been treated by psychoactive drugs for at least 2 months prior to the study were excluded.
- Subjects were randomly assigned to two groups (EEG biofeedback /psychotherapy placebo) by block randomization.
- EEG biofeedback training was provided for 5 weeks(10 sessions, twice per week). Each training session was composed of 6 four minute trials followed by 5 thirty second rest periods
- Psychotherapy placebo session was provided for 5 weeks. These sessions consisted of additional assessment, interpretation of the test results and providing information on course and treatment of mood disorder.
- After subjects completed the training, they participated in a month-long (twice per week) self-training session to maintain a similar mental state during neurofeedback training sessions without feedback system's assistance.
- Subjects who had finished the psychotherapy placebo were referred to other therapists as necessary.
