 Cognitive impairment is a core feature of schizophrenia, as well as a key determinant of functional outcomes for patients with schizophrenia. We previously developed the Japanese version of the Brief Assessment of Cognition in Schizophrenia (BACS-J), and in this study, we evaluated the cognitive functions of healthy subjects using the BACS-J. Data were collected from 709 healthy controls, and data of 292 of them were used for further analyses. The mean (S.D.) age and years of education for the sample were 36.7 (13.5) and 14.6 (2.2), respectively. Each subject gave informed consent to participate in the study. Higher age was significantly correlated with lower composite score and reduced performance on all tests. Men and women differed in their mean performance only in Verbal Memory, in which women were better than men. Higher education was significantly correlated with higher composite score and increased performance in Verbal Memory, Verbal Fluency, and Tower of London. Using the data obtained in this study, individual test scores can be converted into standardized (T and z) scores and composite scores corrected for age and gender.
