Widely regarded as the standard reference in the field, this book, now in its third edition, provides essential tools for understanding and assessing malingering and other response styles in forensic and clinical contexts. An integrating theme for the substantially expanded third edition is the systematic application of detection strategies as conceptually grounded, empirically validated methods that bridge different measures and populations. From leading practitioners and researchers, the volume presents major theoretical, empirical, and clinical advances. Coverage of multiscale inventories and feigned cognitive impairment has been doubled, and new chapter topics include feigned medical presentations, factitious disorders, and forensic evaluations.
