The Detection of Malingering on Measures of Competency to Stand Trial


Book Description

The present study investigated the detection of coached and uncoached malingering on two measures of competency to stand trial: the Georgia Court Competency Test (GCCT) and the Evaluation of Competency to Stand Trial - Revised (ECST-R). Using a simulation research design, undergraduates (n = 101) were randomly assigned into Control (instructed to respond honestly), Uncoached Malingerer (instructed to feign incompetency but did not receive any tips to elude detection), and Coached Malingerer groups (instructed to feign incompetency and received tips to elude detection) and presented with a hypothetical criminal case scenario that required them to undergo an evaluation of their competency to stand trial. Scores on the GCCT and the ECST-R Factual Scale served as indicators of competency, while scores on the GCCT Atypical Presentation (AP) and ECST-R Atypical Presentation (ATP) scales served as indicators of malingering. As expected, results indicate that the two malingering groups appeared markedly impaired on overall competency scores in comparison to the Control group. Furthermore, the two malingering groups appeared markedly elevated on malingering scale scores in comparison to the Control group. Contrary to expectations, test strategy coaching exerted little impact on competency and malingering scale scores. Both malingering scales effectively discriminated between malingerers and honest responders.







Assessing Negative Response Bias in Competency to Stand Trial Evaluations


Book Description

Evaluations of a defendant's competence to stand trial (CST) are probably the most frequently performed forensic evaluations, with estimates in the United States ranging from 60,000 to 70,000 annually. In order for CST evaluations to be considered thorough and accurate, examiners must assess for possible lack of cooperation, feigning, or malingering - the intentional production or gross exaggeration of false or grossly exaggerated physical or psychiatric symptoms, motivated by external incentives. Yet, there are accounts that CST examiners often do not assess for negative response bias, and even if they do nevertheless fail to identify a considerable number of examinees that do feign. Assessing Negative Response Bias in Competency to Stand Trial Evaluations provides readers with a comprehensive guide to assessing whether a defendant has feigned mental impairment during a competency to stand trial evaluation, or simply did not put forth his/her best effort. This book reviews the literature on assessing feigning and negative response bias, with particular focus on issues, tests, and data relevant to CST evaluations, and examines proposed criteria and statistical methods of determining and classifying assessment results. It introduces readers to aspects of the vibrant neuropsychological response style literature, an area many forensic psychologists appear to have overlooked. Additionally, it offers recommendations for research and policy regarding the parameters of CST assessment.

Learning Forensic Assessment


Book Description

Major developments in the field since the publication of Learning Forensic Assessment are integrated in this revised edition, including revised editions of the DSM-5, HCR-20 scale, and child custody guidelines. This textbook is designed for graduate students learning forensic assessment and psychologists coming to forensic practice later in their careers. It is organized around five broad areas: Professional and Practice Issues, Adult Forensic Assessment, Juvenile Forensic Assessment, Civil Forensic Assessment, and Communicating Your Findings. Each chapter begins with a strong teaching and learning foundation. The latter part of each chapter is assessment specific, covering available assessment measures and approaches to assessment. The authors go well beyond simple descriptions of assessment measures and provide a conceptual discussion of the evaluation process that helps the reader understand how assessment measures fit into the overall evaluation process. The evaluation component is geared toward assessing the important aspects of the construct as laid out in the early part of each chapter. Each chapter then concludes with a case example to illustrate the measures and techniques described.




Malingering and Competency to Stand Trial


Book Description

Competency to stand trial (CST) evaluations are among the most frequent forensic psychological evaluations performed each year. The courts depend on these evaluations to consider if a criminal defendant is factually and rationally appreciative of the legal process and rationally able to collaborate with defense counsel in forming a defense. Malingering is always a consideration which muddies the waters of competency evaluation. The current literature review examines the nature of the malingering construct as it relates to CST evaluations. Emerging research results indicates that malingering is better considered on a continuum or as a dimensional construct versus a categorical model. The implications of this on CST evaluation and future testing development is discussed with a call for additional research to further establish the dimensionality of the malingering construct.




Explorations in Criminal Psychopathology


Book Description

When Explorations in Criminal Psychopathology: Clinical Syndromes With Forensic Implications was first published in 1996, the purpose was, in part, to correct an imbalance in the field, specifically with regard to the coverage of the important topic of psychopathology and its relationship to crime. The second edition of this book continues to address the complex approach to this very specific and important aspect of human behavior. Emphasizing on psychopathology from a clinical phenomenological perspective, with legal issues and implications playing a secondary role, an impressive group of con.
