Abstract

Professional organizations recommend inclusion of multiple performance (PVTs) and symptom validity tests (SVTs) (Bush et al., Archives of Clinical Neuropsychology, 20, 419-426, 2005; Heilbronner et al., The Clinical Neuropsychologist, 23(7), 1093-1129, 2009). However, to date, empirically driven recommendations for interpretation of multiple validity indicators are largely absent, and the generalizability of available psychometric data is questionable in clinical practice. The current aim is to provide base rate data and recommendations for interpretation of multiple validity indicators, assuming varying correlations between each PVT at a range of specificity and sensitivity rates. As an initial step, Monte Carlo methodology was validated across 24 embedded and stand-alone validity indicators in seven extant noncompensation-seeking clinical samples. Samples were comprised of patients with psychotic and nonpsychotic psychiatric disorders, as well as different neurological conditions. Strategies are outlined for clinical integration of base rate data for advanced administration and interpretation of multiple validity indicators. In light of the current findings, recommendations are provided to reduce false-positive rates associated with making determinations regarding noncredible test performance.
