Abstract
Base rates of failure (BRFail) on performance validity tests (PVTs) were examined in university students with limited English proficiency (LEP). BRFail was calculated for several free-standing and embedded PVTs. All free-standing PVTs and certain embedded indicators were robust to LEP. However, LEP was associated with unacceptably high BRFail (20–50%) on several embedded PVTs with high levels of verbal mediation (even multivariate models of PVT could not contain BRFail). In conclusion, failing free-standing/dedicated PVTs cannot be attributed to LEP. However, the elevated BRFail on several embedded PVTs in university students suggest an unacceptably high overall risk of false positives associated with LEP.
