Diagnostic Test: Cognitive Function Assessments

The NIMH-Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) is a consensus battery that is considered state-of-the art in the evaluation of cognitive skills for schizophrenia research.(Burton et al., 2013, Harvey, 2014) The complete cognitive battery takes about one hour to administer, and is comprised of 10 subtests measuring seven essential domains of function, with very good reliability and validity.(Nuechterlein 2008, August et al., 2012) The MATRICS subtests have been incorporated into the cognitive battery described below, with supplementary subtests included where indicated within each domain.
