OBJECTIVE: Factor analytic studies of the Positive and Negative Syndrome Scale (PANSS) have consistently isolated a factor that is frequently labeled as 'cognitive'. The present study sought to further explore the factor by examining the relationships between 4 versions of the cognitive factor and a set of neuropsychological tests. METHOD: Thirty-seven inpatients diagnosed with schizophrenia or schizoaffective disorder were assessed with the PANSS and neuropsychological measures. RESULTS: Verbal intelligence and verbal memory were found to be most closely associated with cognitive factor scores. A global rating of illness severity showed greater relationships to cognitive variables than any cognitive factor. CONCLUSIONS: The PANSS cognitive factor may reflect verbal ability and memory, but is not sufficiently comprehensive to be considered as a replacement for direct assessment of cognitive functioning.
