    Abstract

    The present study, utilizing a sample of inpatients with schizophrenia or schizoaffective disorder (n = 167), examined the factor structure of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS).
    Principal axis exploratory factor analysis, multiple factor extraction criteria, and higher-order factor analysis were used.
    Results were inconsistent with the five-factor structure of the RBANS purported in the test manual. Factor extraction criteria
    recommended extraction of one or two factors. Extraction of two factors resulted in a memory dimension and a less homogeneous
    visual perception and processing speed dimension. Higher-order analysis found that a second-order factor, representing general
    neurocognitive functioning, accounted for over three times the total and common variance than the two first-order factors
    combined. It was concluded that although the RBANS appears to be a useful measure of general neurocognitive functioning for
    inpatients with schizophrenia or schizoaffective disorder, clinical interpretation beyond a general factor (i.e., Total Scale
    score) should be done with caution in this population. Limitations of the present study and directions for future research
    are discussed.
