Interpreting Common Performance Validity Tests

This tool combines published meta-analytic estimates of sensitivity, specificity, and the estimated prevalence of invalid performance to support interpretation of performance validity test (PVT) results. The calculated values are intended as an aid to clinical interpretation and should not be interpreted as definitive probabilities for an individual examinee.
