Detection of overreporting of psychopathology on the Personality Assessment Inventory: a meta analytic review.
The Personality Assessment Inventory (L. C. Morey, 1991) includes 3 measures for identifying overreporting of psychopathology: the Negative Impression scale (NIM) Malingering Index (MAL) and Rogers Discriminant Function (RDF) Meta analysis revealed that each measure was a strong predictor of uncoached (NIM, d 1.48, k 23; MAL, d 1.15, k 19; RDF, d 1.13, k 15) and coached malingering (NIM, d 1.59, k 8; MAL, d 1.00, k 6; RDF, d 1.65, k 3) For uncoached malingering, effects were larger in simulation than criterion groups studies, for identifying feigning of severe mental disorders than mood/anxiety disorders, and when feigners were compared to unimpaired honest respondents as opposed to patients. Cut scores of NIM or 81 and MAL or 3 resulted in the highest overall classification rates for identifying feigning. (PsycINFO Database Record (c) 2009 APA, all rights reserved)
