Assess Feigning and Response Styles in Defendants With Two New Forensic Measures

LUTZ, Fla., Oct. 28 /PRNewswire/ -- Psychologists can now assess deliberate distortions of symptoms and assess feigning with two new psychological tests.

The Structured Interview of Reported Symptoms, 2nd Edition (SIRS-2) by Richard Rogers, PhD, ABPP effectively detects feigning in forensic settings. The SIRS-2 was developed to assess deliberate distortions in the self-report of symptoms. Each scale produces useful information on how a particular client may distort or fabricate his or her symptoms. Long considered the gold standard in forensic measures, this updated edition helps evaluate feigning of psychiatric symptoms in greater detail with expanded scoring and classification. The primary focus of the SIRS-2 is on the evaluation of feigning and the manner in which it is likely to occur, such as the exaggeration of symptom severity rather than a fabrication of symptomatology. A new Spanish language booklet is also available.

The Inventory of Legal Knowledge™ (ILK™) by Jeffrey E. Musick, PhD, ABPP and Randy K. Otto, PhD, ABPP assists forensic examiners in assessing response styles of defendants undergoing evaluations of adjudicative competence. Written in simple language, the ILK contains 61 true-or-false items about the legal process. Orally administered by an examiner in about 15 minutes (making the instrument suitable for illiterate defendants), the ILK can be used anywhere -- including jails and other secure facilities -- and scored quickly. The ILK identifies defendants as feigning based on scores significantly lower than those expected by chance and based on scores lower than those obtained by relevant normative groups.
