Further Validation Of The Mmpi-2 And Mmpi-2-Rf Response Bias Scale: Findings From Disability And Criminal Forensic Settings, Dustin Wygant, Martin Sellbom, Roger Gervais
Dustin B. Wygant
The present study extends the validation of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) Response Bias Scale (RBS; R. O. Gervais, Y. S. Ben-Porath, D. B. Wygant, & P. Green, 2007) in separate forensic samples composed of disability claimants and criminal defendants. Using cognitive symptom validity tests as response bias indicators, the RBS exhibited large effect sizes (Cohen's ds = 1.24 and 1.48) in detecting cognitive response bias in the disability and criminal forensic samples, respectively. The scale also added incremental prediction to the traditional MMPI-2 and the MMPI-2-RF overreporting validity scales …
Criminal Profiling Methods, Wayne Petherick
Criminal Profiling Methods, Wayne Petherick
Wayne Petherick
Extract:As an investigative aid, criminal profiling has received a great deal of attention from academic audiences and popular culture (Petherick, 2003), and significant advances have been made in both practical and theoretical terms. Even though our collective knowledge about this area has grown, there is still much about the process that remains a mystery. For example, there is little acknowledgment or understanding of the logic or reasoning employed within the profiling process (see Chapter 2), or that there are indeed different methods employed within the profiling community. Of more concern is the fact that many practitioners continue to confuse these …
Criminal Profiling As Expert Evidence, Wayne Petherick, David Field, Andrew Lowe, Elizabeth Fry
Criminal Profiling As Expert Evidence, Wayne Petherick, David Field, Andrew Lowe, Elizabeth Fry
Wayne Petherick
Extract:
Profiling evidence has been accepted in courts in the United States in both trial and sentencing phases, but other jurisdictions have been more cautious in their acceptance. For example, courts in the United Kingdom and Australia have been reluctant to introduce profilers as experts, even though profiling has been given some exposure in courts operating at the lower end of the justice system. The reasons for this reluctance are varied but include a lack of uniformity processes and outcomes, fragmentation of methods, and conflict between profiling organizations and practitioners. In short, there are many methods of profiling, and not …
The Fallacy Of Accuracy In Criminal Profiling, Wayne Petherick
The Fallacy Of Accuracy In Criminal Profiling, Wayne Petherick
Wayne Petherick
Extract:
The defining criterion by which the utility of a particular tool is often judged is its accuracy or sensitivity of detection. We place little faith in that which is inaccurate or in those things that do not detect what they are meant to detect. Things are no different in the profiling community, and the most common measure by which a profiler claims utility is how close his or her approximations are to an offender, if one is caught. As will be shown in this chapter, with the craft being the way it is, this is probably the worst possible …
Metacognition In Criminal Profiling, Barry Woodhouse, Wayne Petherick
Metacognition In Criminal Profiling, Barry Woodhouse, Wayne Petherick
Wayne Petherick
Extract:
As with many professions, one of the more serious problems that confronts the profiling community is that of the inept examiner. Deliberately unethical behavior is one thing, but ongoing incompetence because of profiler ignorance is something else entirely. In some instances, ignorance is the result of a metacognitive deficit caused by a lack of study, a lack of training, or a general lack of mental dexterity. In such instances, the profiler will continually do the wrong thing, such as using flawed methods and erroneous logic, because he lacks the ability to recognize his own ineptitude; the profiler cannot perceive …
