Evaluación de simulación de incapacidad laboral permanente mediante el Sistema de Evaluación Global (SEG)

Research on credibility and faking is essential in different areas of psychology and especially in the forensic field. The investigations performed by Arce and Farina are recognised as being among the most notable of all the existing investigations, with the development of the Global Evaluation System (GES) that has been found to be especially effective in assessing the credibility of testimony and malingering mental health cases. The application of this procedure to 20 people accused under the judicial system of Social Security fraud for malingering a permanent work incapacity by way of a mental disorder, showed that the procedure described in the GES was effective for the correct classification of the malingers. Furthermore, data supported the categorising of malingers, consisting of whole malingers (those mentally healthy that effectively simulate a permanent work incapacity), partial malingers (those with temporary or no mental work incapacity disease, who claim for a permanent work incapacity), over malingers (those with permanent work incapacity mental disorders who exaggerate the severity of their mental health) and incompetent malingers (those who claimed to have permanent work incapacity but in their mental health assessment, were observed to have no mental health disorder.). Protocols for the forensic evaluation of malingering fitted to each categorization derived from the results obtained. The theoretical and practical implications of forensic assessment are discussed.
