## IPIP-NEO - Big Five Personality, 120-Item Version

The **IPIP-120** is a psychological inventory based on the **Big Five** model (or the five major personality factors), developed as part of the International Personality Item Pool (**IPIP**).

This version uses scores calculated with the [Five-Factor-E](https://github.com/NeuroQuestAi/five-factor-e) library, providing accurate and reliable analysis of personality traits.

The IPIP-120 is a shortened version of the IPIP-300, consisting of 120 items that assess the five major personality traits:

- Openness
- Conscientiousness
- Extraversion
- Agreeableness
- Neuroticism

This inventory is widely used in academic research and practical applications, offering an efficient tool for measuring key aspects of personality.
