Abstract

This study examined the criterion and construct validity of a brief computerized cognitive test battery (CogState Schizophrenia Battery) compared to a conventional cognitive test battery recommended by the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) consensus. The CogState and MATRICS batteries yielded comparable effect sizes in comparing patients with schizophrenia to healthy controls (Cohen's ds = -1.50 for both batteries). Moderate to large correlations were observed between CogState and MATRICS measures of processing speed, attention/vigilance, working memory, verbal and visual learning, reasoning/problem solving, and social cognition (rs =.56-.79)...
