Factor structure of the MATRICS Consensus Cognitive Battery (MCCB) in schizophrenia

These analyses suggest that the six MCCB “domains” as constructed can be collapsed into fewer domains composed of multiple item scores; they also support the notion that impaired processing speed is a fundamental cognitive deficit in schizophrenia and that MCCB performance is related to functional capacity. Cognition and functional capacity measures require more research to determine if they differ.
