The go-to resource for clinical and forensic practice has now been significantly revised with 85% new material, reflecting the tremendous growth of the field. Leading authorities synthesize the state of the science on symptom feigning in cognitive testing and present evidence-based recommendations for distinguishing between credible and noncredible performance. A wide range of performance validity tests (PVTs) and symptom validity tests (SVTs) are critically reviewed and guidelines provided for applying them across differing cognitive domains and medical, neurological, and psychiatric conditions. The book also covers validity testing in forensic settings and with particular populations, such as ethnic and linguistic minority group members.
