A series of t tests and correlational analyses were conducted in both samples. We anticipated that, in voluntarily admitted psychiatric inpatients (N = 1,011) and individuals receiving outpatient services in a university-affiliated psychology clinic (N = 521), those indicated as underreporting would produce lower mean scores across SUI and extra-test measures of suicide risk, and that the magnitudes of the associations between SUI and extra-test scores would be strongest for those underreporting. The aim of this research is to examine whether underreporting based on elevated Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) K-r and L-r scale scores may aid in identifying patients with suppressed scores on the Suicide/Death Ideation scale (SUI) and extra-test measures of suicide risk. No new norms were collected for the MMPI-2-RF.Detection of underreporting in suicide risk assessment remains a significant concern in clinical practice. The MMPI-2-RF T scores are non-gendered and non-K-corrected. Norm Group: The MMPI-2-RF normative sample is drawn from the MMPI-2 normative sample and consists of 2, 276 men and women between the ages of 18 and 80 from several regions and diverse communities in the U.S. Minimum Reading Level: 5th grade (Lexile average), 4.5 grade (Flesch-Kincaid) Administration: Computer, CD, or paper-and-pencil Publisher: University of Minnesota Press Test Authors: Yossef Ben-Porath, Ph.D., and Auke Tellegen, Ph.D.

The MMPI-2-RF, like all MMPI instruments, is available for purchase from Pearson Assessments. The MMPI-2-RF, published in 2008, is a 338–item self-report measure linked conceptually and empirically to modern theories and models of psychopathology and personality.
