IPIP

Short Form for the IPIP-NEO (International Personality Item Pool Representation of the NEO PI-R™)

Purpose of this inventory

  • The primary purpose of this on line inventory is to educate the public about the five factor model of personality.
  • More specifically, the report explains the likely consequences of one's standing on five broad personality domains.
  • These broad domains cover normal differences in personality that should be obvious to people who know you well.
  • Secondarily, this inventory estimates your standing on the 5 broad domains and 30 sub domains of personality.
  • The inventory does not reveal hidden, secret information about you nor does it assess serious psychological disorders.
  • The report is designed to be objective, not pleasing or flattering.
  • Measurement error, misunderstandings, carelessness, and mischievous responding can invalidate the report.
  • If knowledgeable acquaintances disagree with the test results, then the results are wrong.
