Problem: According to Lilienfeld and Widows (2005), the PPI-R Total score had a test-retest reliability of .93 in a community sample; for the content scales, the test-retest reliabilities ranged from .82 to .95. Additionally, the Total score for a community sample had an internal consistency of .92, with the content scales ranging from .78 to .87. Lilienfeld and Widows (2005) also provide support for the construct and discriminant validity of the PPI-R; the total score was found to correlate moderately to highly with other psychopathy measures, and it demonstrated adequate discriminant validity from measures assessing theoretically dissimilar constructs.
