Inwald Personality Inventory

Personality test
The Inwald Personality Inventory (IPI) is a standardized personality test of adult pathology and personality. The IPI is utilized by public safety services to assess the fit of possible employees in public safety and law enforcement positions. The assessment can also indicate deviant behavior patterns. The original IPI was created by Dr. Robin Inwald in 1980, and was published by Hilson Research. An updated version, the IPI 2, was released in 2011 by the Institute for Personality and Ability Testing, Inc. (IPAT). Original items from the IPI were reorganized in the creation of the current edition. While the IPI 2 features diagnostic criteria, it is not meant to be used as a mental health disorder diagnostic tool.

Scoring for the IPI 2 involves comparison of scores with those of other public safety professionals in an effort to better predict proper fit for applicants. Scores for each scale are scores using T scores, and those scores that are above a t score of 60 are considered to be “elevated”, thereby warranting further exploration. In testing validity of the IPI 2, internal consistency was measured using Cronbach's Alpha (overall=0.52). Significant correlations (<.05) were analyzed between IPI 2 scales and MMPI 2 RF and the PAI (Personality Assessment Inventory). Results are combined with Field Training Officer (FTO) Predictions, in order to provide a more complete analysis. Results from FTO Predictions, coupled with IPI 2 results that were used in discriminant function analysis, lead to one of two outcomes for the categories of Control of Conflict, Public Relations, Report Writing, and Overall FTO Rating. The two outcomes for each of these categories are: ″likely to meet expectations″ or ″not likely to meet expectations″.
