This chapter reviews the most popular and promising instruments for assessing poor effort or feigned cognitive impairment. Referred to as performance validity tests (PVTs), these instruments vary from very brief to quite long and also vary substantially in sophistication and performance. The advantages and disadvantages of each are reported along with the costs of their use (time and money), diagnostic statistics, and recommended cutoff scores. The various PVTs discussed in the chapter are well validated in neurological samples but less so in psychiatric ones. The chapter concludes by noting that although many PVTs are now described as effort tests, there has been no research to accurately measure how much mental effort different tests require.
