Abstract
Current problems and neuropsychological assessment strategies of malingering detection (assessment of negative response bias or non-optimal test behaviour) are reviewed. First, the paper discusses major conceptual problems inherent in the definition of malingering, factitious disorders, and somatoform disorders. Traditional and modern test approaches and diagnostic procedures are reviewed. Two case vignettes illustrate the application of particular strategies for malingering assessment. In German speaking countries, malingering research has not yet aroused profound interest comparable to that in English speaking countries. Diagnostic standards and instruments still have to be refined.
