Questionnaire / instrument: IPIP-NEO-120
What does it measure?
A detailed profile of openness, conscientiousness, extraversion, agreeableness and neuroticism. Each trait is divided into six facets, giving 30 more specific descriptions of your typical thoughts, feelings and behaviour.
Where does it come from?
John A. Johnson developed IPIP-NEO-120, published in 2014, by selecting items from the longer IPIP-NEO inventory. The questions belong to the International Personality Item Pool, initiated by Lewis R. Goldberg.
How is the result calculated?
Each facet uses four items and each broad trait uses 24. Reverse-worded items are scored in the opposite direction. The report shows trait and facet scores; reference percentiles compare responses with Johnson’s online sample.
What can the result tell you?
This is a self-report personality profile, not a clinical diagnosis or a division into fixed personality types. A position on the response scale and a percentile are different: the latter depends on the reference sample, which is not representative of every population.
