The Detection Of Malingering On Measures Of Competency To Stand Trial: A Study Of Coached And Uncoached Simulators, Rachael Elizabeth Springman

Dissertations

Competency to stand trial evaluations serve as the most frequently requested type of forensic evaluation. Despite the court?s need for accurate and credible information, defendants referred for competency evaluations may be motivated to malinger incompetency in order to avoid trial and gain personal liberty (Rogers, Sewell, Grandjean, & Vitacco, 2002). Furthermore, motivated malingerers can obtain information about tests prior to evaluations, particularly from the Internet and their attorneys. Previous research has demonstrated that coaching on test-taking strategies helps malingerers avoid detection on psychological tests like the MMPI-2 (e.g., Storm & Graham, 2000), but no research has examined the effects of …
