Abstract

Schizophrenic patients demonstrate impairments in several key dimensions of cognition. These impairments are correlated with important aspects of functional outcome. While assessment of these cognition disorders is increasingly becoming a part of clinical and research practice in schizophrenia, there is no standard and easily administered test battery. The BACS (Brief Assessment of Cognition in Schizophrenia) has been validated in English language [Keefe RSE, Golberg TE, Harvey PD, Gold JM, Poe MP, Coughenour L. The Brief Assessment of Cognition in Schizophrenia: reliability, sensibility, and comparison with a standard neurocognitive battery. Schizophr. Res 2004;68:283–97], and was found to be as sensitive to cognitive dysfunction as a standard battery of tests, with the advantage of requiring less than 35 min to complete. We developed a French adaptation of the BACS and this study tested its ease of administration and concurrent validity. Correlation analyses between the BACS (version A) and a standard battery were performed. A sample of 50 stable schizophrenic patients received the French Version A of the BACS in a first session, and in a second session a standard battery. All the patients completed each of the subtests of the French BACS . The mean duration of completion for the BACS French version was 36 min (S.D. = 5.56). A correlation analysis between the BACS (version A) global score and the standard battery global score showed a significant result (r = 0.81, p < 0.0001). The correlation analysis between the BACS (version A) sub-scores and the standard battery sub-scores showed significant results for verbal memory, working memory, verbal fluency, attention and speed of information processing and executive functions (p < 0.001) and for motor speed (p < 0.05). The French Version of the BACS is easier to use in French schizophrenic patients compared to a standard battery (administration shorter and completion rate better) and its good psychometric properties suggest that the French Version of the BACS may be a useful tool for assessing cognition in schizophrenic patients with French as their primary language.
