Abstract

Objective: The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was designed as a cognitive screening test, providing both a total scale score and five specific cognitive ability index scores. This study examined the test-retest stability of the RBANS in individual patients with schizophrenia relative to a healthy comparison group. Method: A total of 181 patients with schizophrenia or schizoaffective disorder were recruited from three clinical settings. Healthy comparison subjects were recruited as part of the RBANS standardization. Participants were administered one form of the RBANS on one occasion and another form at a later date, with intervals ranging from 1 to 134 days. Results: Intraclass correlation coefficients for the RBANS total scale were 0.84 for the patients with schizophrenia and 0.77 for the healthy comparison subjects. Confidence intervals and percentile data for the total scale change scores were similar for both groups. Conclusions: The RBANS demonstrated reasonable intraclass correlation coefficient test-retest reliability for both schizophrenia patients and healthy comparison subjects. Confidence intervals are comparable to those previously published for the WAIS-R and Wechsler Memory Scale-Revised, suggesting that retest measurement error is not dramatically increased in the RBANS, despite the brevity of the test. These data may serve as an informative guide for using the RBANS to evaluate neuropsychological change on the level of the individual subject.
