Forty patients with diagnosis of schizophrenia, who had been stabilized from psychotic symptoms and currently suffering from dominant negative symptoms will be recruited and undergo accelerated iTBS treatment for 5 consecutive sessions each day for 5 working days. Participants will be followed up immediately, 1 month and 3 months after the end of treatment.
