Is the repeatable battery for the assessment of neuropsychological status factor structure appropriate for inpatient psychiatry? An exploratory and higher-order analysis.
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.

ABSTRACT: Huntington disease (HD) is a neurodegenerative disease associated with cognitive, motor, and psychiatric deterioration over time. Although there is currently no cure for HD, there has been a surge of clinical trials available to patients with HD over the past 5 years. However, cognitive measures have generally been lacking from these trials. A brief, repeatable neuropsychological battery is needed to assess cognitive endpoints. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) may be useful for assessing change in interventional studies or for clinical monitoring. A total of 38 patients with HD were assessed using the RBANS, other cognitive tests, and the standardized HD battery (Unified Huntington's Disease Rating Scale, UHDRS) at two clinic visits approximately 16 months apart. The RBANS Attention Index, as well as individual subtest scores on Coding, Digit Span, List Recognition, Figure Copy, and Figure Recall all declined significantly over this interval. Performance on the UHDRS cognitive tests (Symbol Digit Modalities; Stroop Color, and Stroop Word) also declined, as did functional capacity. Results suggest that cognitive changes were detected both on established cognitive tasks used in HD research and on the RBANS in patients with measurable functional decline. The RBANS provided additional information about other cognitive domains affected (e.g., memory) and may be a useful measure for tracking longitudinal change.Journal of Clinical and Experimental Neuropsychology 10/2009; 32(6):573-8. · 1.86 Impact Factor

ABSTRACT: Cognitive change following bilateral subthalamic nucleus (STN) deep brain stimulation (DBS) surgery in those with Parkinson's disease (PD) has led to equivocal results. The current study applied a standardized regression-based (SRB) method based on 20 medically managed PD patients and 20 STN DBS PD surgical patients who were administered the Repeatable Battery of Neuropsychological Status (RBANS). Of the medically managed PD participants, 94% remained stable compared to 73% of the DBS group. In the DBS group cognitive change was noted on the Total scale and the Immediate Memory Index. A secondary analysis also revealed reliable change on several subtest scores. Although preliminary, the current study provides change parameters for post DBS surgery on this brief battery.The Clinical Neuropsychologist 10/2010; 24(8):1339-54. · 1.68 Impact Factor
