Insight controlled for cognition in deficit and nondeficit schizophrenia.

ABSTRACT

Patients with deficit schizophrenia have worse cognition and poorer social functioning compared to the nondeficit ones. Insight is another domain in which these two groups might differ, but data on insight impairment in deficit versus nondeficit schizophrenia are still scarce. We compared 29 patients with deficit schizophrenia to 44 nondeficit patients and found a tendency to poorer insight in the deficit group. However such tendency disappeared when analysis was controlled for cognition, a domain in which both groups differed significantly. This finding reinforces the pressing need for simultaneous assessment of the several dimensions or domains of schizophrenic psychopathology.
