Background: schizophrenia is a psychiatric disorder in which a lot of cognitive functions including memory, attention, motor skills, executive functions and intelligence are compromised. Numerous empirical studies showed that schizophrenic patients have problem in sustain retention and memory activity. The objective of this study was a comparison between effectiveness of three types of music on memory activity and sustain retention in schizophrenic patients. Material and Methods: A total of 60 schizophrenic patients (30 males , 30 females) 18-48 years old were selected from available sampling frame. Participants were otherwise healthy except for schizophrenia. Wechsler Memory Scale and cognitive diagnostic battery Kay test were taken from all subjects. Then patients were randomly divided into three experimental groups (Iranian classic, western classic and pop music) and three control groups. There were 10 participants (5 male, 5 female) in each group. After taking these tests, music therapy course was performed on experimental groups. After music therapy sessions were completed, tests were taken again from groups. Results: Covariance analysis results indicated that music therapy is overall effective on memory activity. But type of music had no effect in improving memory activity. There wasn’t significant difference between groups considering type of music. Furthermore, covariance analysis showed that music therapy is totally effective on sustain retention and type of music is effective in this intervention. Pop music had the most effectiveness on schizophrenic patients in improving sustain retention. Conclusion: Performing music therapy improves memory and retention. More over, using pop music particularly has the most effect in improving sustain retention in schizophrenic patients.
