Sensitivity of MMPI-2 validity scales to underreporting of symptoms

Article Abstract:

Standard and supplementary scales are used to investigate underreporting of psychopathological symptoms by individuals given the Minnesota Multiphasic Personality Inventory - 2. The study is participated in by 100 undergraduate students who are equally divided into two groups, with one group taking the test under fake-good instructions and the other given standard instructions. The results show that fake good participants have higher scores than the standard participants on all underreporting scales. The findings' implications are discussed.

Faking specific disorders and temporal response consistency on the MMPI-2

Article Abstract:

Test-takers faking specific disorders show consistency in symptom description on repeated testing and the disorder type can affect temporal response consistency. Participants faking Posttraumatic Stress Disorder (PTSD) show greater response consistency on 2-week serial testings on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) as compared to those faking closed-head injury (CHI). While no significant effect for time is seen, participants faking a disorder obtain high scores on validity scales sensitive to overreporting.

Overreporting of closed-head injury symptoms on the MMPI-2

Article Abstract:

Overreporting of closed-head injury (CHI) symptoms on the Minnesota Multiphasic Personality Inventory 2 is examined by comparing the scores of four groups on the test's validity scales. The four groups consist of nonclinical participants given standard instructions, nonclinical participants asked to fake CHI symptoms, non-compensation-seeking CHI patients and compensation-seeking CHI patients. The scores are highest among nonclinical participants faking CHI and among compensation-seeking participants.
