Psychology Theses & Dissertations

The study examined the applicability of various validity measures and their ability to identify patterns of invalid responding (i.e., malingering) in an archival sample of civil forensic litigants. A latent clustering approach was used to create profiles comprised of the response patterns from validity measures of different domains including three performance validity tests (PVT), five symptom validity scales (SVT), and an embedded validity indicator (EVI).
