International Personality Item Pool

The International Personality Item Pool is a collection of public-domain personality measures designed to assess various psychological traits. It is commonly used to measure the big five personality factors: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism.

Yes, the International Personality Item Pool (IPIP) can be adapted to measure traits beyond the traditional Big Five personality factors. While it is most commonly associated with assessing the Big Five, this flexible personality test also includes scales for narrower facets, making it a versatile tool in personality psychology. Researchers and professionals can tailor the IPIP to suit specific study designs or unique assessment needs.

The International Personality Item Pool (IPIP) provides free access to items that correlate highly with the same factor structure measured by the Revised NEO Personality Inventory. Both tools assess similar traits based on the big five factor markers, but the IPIP is open-source and freely available, making it a cost-effective alternative for researchers or professionals.
