APP and Cognitive impairment: In addition to the correlation observed between severity of cognitive deficits clinically measured using CGI-SCHs cognitive scale and severity of functioning measured by Mini-ICF-APP, we also detected significant correlations with the MMSE and with three out of six BACS domains; this finding was not unexpected, particularly in view of the well established relationship between cognitive and real-world functioning deficits in schizophrenic patients [40].
