Title: The Difference in Negative Scale Score Measured with Positive and Negative Syndrome Scale in Schizophrenic Male Patient Treated with Risperidone in Addition to Vitamin E and Treated with Risperidone Alone at Prof. Dr. M. Ildrem Mental Hospital Medan
Abstract: OBJECTIVES: The objectives of the study were to investigate the difference in negative scale score in schizophrenic male patients that received vitamin E-fortified risperidone and those receiving risperidone treatments alone. METHODS: This study was a pre- and post-test experimental design which compared two groups; a group of men with schizophrenia who were given risperidone treatment with added Vitamin E and another group of men with schizophrenia who were given only risperidone treatment. The study was conducted at the outpatient clinic of Prof.dr. M. Ildrem Mental Hospital Medan, North Sumatra within August to November 2019. The study has been approved by the Research Ethics Committee of the Faculty of Medicine, North Sumatera University. The instrument used to assess negative scale on the subjects is PANSS. RESULTS: We found that statistical analysis using corrected Mann–Whitney U-test obtained p < 0.001 (p < 0.05). CONCLUSIONS: There was a strongly significant difference in negative scale Positive and Negative Syndrome Scale (PANSS) scores on 4th and 8th weeks in the group which received risperidone treatment with additional Vitamin E compared to the other group that received risperidone alone.
