Approximately, 84%-94% patients with schizophrenia demonstrate cognitive impairment. Brief assessment of cognitive function for schizophrenia patients to be used in clinical practice is not available in Indonesia. This study aimed to assess the validity and reliability of the Indonesian version of the Brief Assessment of Cognition in Schizophrenia (BACS-I). 50 patients with schizophrenia who have been in remission phase, were assessed using BACS-I between April 2018 and September 2018 in two separate session at range interval of 14-90 days. Consistency in assessment score between the session was evaluated using test-retest reliability. The concurrent validity was assessed using standard battery. The median of completion for the BACS-I was 22.08 min (16.13 min - 29.79 min) and show high test-retest reliability (ICC = 0.94). Correlation with standard test are very weak until moderate (0.09 - 0.59), but only significantly in verbal memory, working memory, and motor speed. This study results indicates that BACS-I has satisfactory reliability to assess cognitive function in schizophrenia patients.
