Effect of symptom information and validity scale information on the malingering of depression on the MMPI-2.

MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) data from college students who were attempting to malinger depression (199 women and 171 men) were compared to MMPI-2 data from students who responded honestly (50 women and 45 men). Mean MMPI-2 scores were compared with analyses of variance, and students' success in malingering depression was evaluated with criteria based on cutting scores for validity indexes and on the clinical scales commonly associated with depression. Students who were given information about the validity scales or about the symptoms of depression were more successful at malingering than students who received no information, indicating that malingerers of depression may be able to elude detection by the MMPI-2 if they are informed about the validity scales or the symptoms of depression.
