Abstract
Neuropsychology practice organizations have highlighted the need for thorough evaluation of performance validity as part of the neuropsychological assessment process. Embedded validity indices are derived from existing measures and expand the scope of validity assessment. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is a brief instrument that quickly allows a clinician to assess a variety of cognitive domains. The RBANS also contains multiple embedded validity indicators. The purpose of this study was to synthesize the utility of those indicators to assess performance validity. A systematic search was completed, resulting in 11 studies for synthesis and 10 for meta-analysis. Data were synthesized on four indices and three subtests across samples of civilians, service members, and veterans. Sufficient data for meta-analysis were only available for the Effort Index, and related analyses indicated optimal cutoff scores of ≥1 (AUC = .86) and ≥ 3 (AUC = .85). However, outliers and heterogeneity were present indicating the importance of age and evaluation context. Overall, embedded validity indicators have shown adequate diagnostic accuracy across a variety of populations. Recommendations for interpreting these measures and future studies are provided.
