title: A comparison of simulation and known groups in the detection of malingering on the MMPI-2.
abstract: Three groups of 30 inmates, one instructed to respond honestly, one to fake being mentally ill, and one to fake schizophrenia after being educated to its symptoms, were administered the MMPI-2. These simulation groups were compared to two forensic evaluation groups of 30 pretrial defendants, one believed to be mentally ill and one suspected of malingering based on their psychiatric history, in order to compare the results of simulation with those of the forensic context. The results demonstrated that those instructed to feign psychiatric disorder and those suspected of malingering in the forensic context scored significantly higher on all MMPI-2 validity indicators than did those with a history of psychiatric treatment and those instructed to respond honestly, yet did not differ from each other. These findings suggest that the results of simulation designs are comparable to those obtained from forensic subjects. The F(p) Scale failed to add incrementally to F in discriminating the two defendant groups.
