Cross-Validating the Executive Errors Scale of the Repeatable Battery for the Assessment of Neuropsychological Status.

Abstract

The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was developed to briefly measure a broad range of cognitive abilities, but it initially lacked a scale to evaluate executive functioning. Robert Spencer and colleagues recently created an Executive Errors scale (RBANS-EE) that quantified executive functioning (EF) errors committed during four RBANS subtests: List Learning, Semantic Fluency, Coding, and List Recall. In the present paper we cross-validated the RBANS-EE with a sample of 234 U.S. military veterans (M AGE = 67.2, SD = 11.5years; M EDUCATION = 13.3, SD = 2.4years) who completed the RBANS and various EF criterion measures as part of neuropsychological assessments they underwent during their clinical care. We found the RBANS-EE to be significantly correlated with most of the criterion EF measures. The RBANS-EE scale demonstrated modest ability to classify EF impairment at mild and severe levels; and, similarly, the RBANS-EE was modestly capable of accurately classifying those veteran respondents who were determined to have or to not have a neurocognitive disorder. Overall, the RBANS-EE can be quickly calculated, adds no administration time to an RBANS assessment, and yields useful scores to screen for EF dysfunction without replacing standalone EF tests.
