This study aimed to test the reliability and validity of the Chinese version of the BACS in a Chinese-speaking population. Methods: All participants in this study (66 patients with schizophrenia [mean age: 41.2 years, 57.6% male] and 66 age- and sex-matched healthy controls) were from Taiwan and assessed using the BACS and the University of California, San Diego (UCSD) Performance-Based Skills Assessment, Brief Version (UPSA-B). Thirty-eight of the 66 patients with schizophrenia received a reassessment using the BACS.

In both patients and controls, the BACS composite scores were positively correlated with all BACS subscales (P |
