Easily Administer, in 25 Minutes or Less, this Measure of Psychopathy that can be Used in Both Clinical and Nonclinical Settings
The PPI-R is a 154-item self-report measure of both global psychopathy and the component traits of psychopathy.
- Can detect response styles such as positive or negative impression management and random or careless responding.
- Rather than focusing exclusively on antisocial or criminal behaviors, the PPI-R measures the continuum of psychopathic personality traits.
- Standardized and validated for use with men and women in a community/college sample that reflects 2002 U.S. Census statistics for race/ethnicity, educational background, and geographic area. Also includes normative data for a male offender sample.
- Useful in a variety of settings, particularly correctional facilities, forensic practice, substance abuse treatment centers, and research.
- This revision lowered the reading level, reworded culturally specific idioms, and reduced its length to make the PPI-R more applicable to individuals in forensic and clinical samples while retaining its utility in nonclinical (e.g., student, community) samples.

FAQs
What is the technical information of the PPI™-R?
Test
- Materials required for administration and scoring of this revised version of the PPI, the PPI-R, are the Professional Manual, the reusable PPI-R Item Booklet, the carbonless PPI-R Response Form, the PPI-R Scoring Summary/Profile Form, a hard-point pen or a sharpened pencil, and a flat writing surface.
- Respondents record item responses directly onto the carbonless Response Form. The bottom page of the Response Form and the Scoring Summary/Profile Form are used by the examiner to obtain Validity scale scores as well as to calculate scale raw scores, T scores, percentiles, and graphical representations of the respondent’s performance by means of hand-scoring and plotting.
- The Scoring Summary provides instructions for the scoring of the PPI-R Content scales, Validity scales, Total score, and factor scores, in addition to summary tables for recording raw scores, T scores, percentiles, and 90% confidence intervals.
- Conversion of raw scores to T scores is achieved through use of the normative tables provided in the Appendix tables of this Professional Manual. The individual’s PPI-R T scores can be plotted on the Profile Form to provide for a graphical representation of an individual’s PPI-R scores relative to those of the comparative normative sample.
