The Psychopathic Personality Inventory (PPI-Revised) is a personality test for traits associated with psychopathy in adults. The PPI was developed by Scott Lilienfeld and Brian Andrews to assess these traits in non-criminal (e.g. university students) populations, though it is still used in clinical (e.g. incarcerated) populations as well.
Total symptom severity is calculated by summing up all the individual item severity scores. For example, in the CAPS-IV scoring, to meet criteria for a symptom, the symptom must have an intensity score of 2 (on a scale or 0-4) or greater and a frequency score of 1 (on a scale of 0–4) or greater.
A study by Chad Brinkley in 2001 tested the concurrent and construct validity of the LSRP with the PCL-R with a sample of prison inmates. [10] Small to moderate correlations were found between the LSRP and PCL-R, as well as associations between primary and secondary psychopathy ("factor 1" and "factor 2" in the PCL-R).
Many large-scale clinical tests are normed. For example, scores on the MMPI are rescaled such that 50 is the middlemost score on the MMPI Depression scale and 60 is a score that places the individual one standard deviation above the mean for depressive symptoms; 40 represents a symptom level that is one standard deviation below the mean.

All of these scores are used to compute an overarching score that indicates a person's anxiety severity. [4] The Hamilton Anxiety Rating scale has been considered a valuable scale for many years, but the ever-changing definition of anxiety, new technology, and new research has had an effect on the scale's perceived usefulness.
