Coaching had no effect on the ability of the research participants to feign more successfully than those participants who received no coaching. For the MMPI-2, the Psychopathology F scale, or F(p), proved to be the best at distinguishing psychiatric patients from research participants instructed to malinger, although the other F scales (i.e., F and Fb) were also effective. For the PAI, the Rogers Discriminant ...Keywords
