New error type and recall consistency indices for the Brief Visuospatial Memory Test - Revised: performance in healthy adults and multiple sclerosis patients.

The Brief Visuospatial Memory Test - Revised (BVMT-R) is a reliable and well-validated test of visual-spatial memory with six equivalent, alternate forms. While the BVMT-R is commonly used in the evaluation of patients with craniocerebral trauma, schizophrenia, and multiple sclerosis (MS), the range of variables is limited. In this study, we developed new BVMT-R error and recall consistency indices. Inter-rater reliability and validity for the new indices were examined in 70 MS patients and 72 healthy volunteers. In addition to poorer general performance, MS patients made more intrusions and qualitative errors, and showed a trend toward poorer BVMT-R recall consistency. Findings suggest these error types and inconsistent learning contribute to poorer recall of visual material in MS.
