Validation of the Persian version of the Schizophrenia Cognition Rating Scale (SCoRS) in patients with schizophrenia.

The Schizophrenia Cognition Rating Scale (SCoRS) is an interview-based assessment of cognition that involves interviews with patients and informants. The SCoRS has shown good reliability, validity, and sensitivity to cognitive impairment in schizophrenia, with the advantage of brief administration and scoring time. The present study aimed to test the concurrent validity of the Persian version of the SCoRS. A group of 35 patients with schizophrenia and a group of 35 healthy controls received the Persian-SCoRS in the first session, and a standardized performance-based cognitive battery, the Brief Assessment of Cognition in Schizophrenia (BACS), in the second session.Our results indicated that the Persian version of the SCoRS was sensitive to cognitive impairment in the patients. The Persian SCoRS global rating was significantly associated with the composite score generated from the Persian version of the BACS and predicted functional outcomes as measured by Global Assessment of Functioning (GAF) and World Health Organization Quality of Life (WHO QOL). A Persian version of the SCoRS, an interview based measure of cognition that included informants, is related to cognitive performance and global functioning.
