The NEO Five-Factor Inventory (NEO-FFI) is the shortened version of the NEO-PI-3.
It takes 10 to 15 minutes to complete and consists of 60 items. The full version consists of 240 items and takes up to an hour to finish.
The NEO-FFI still retains its reliability and validity and measures openness, conscientiousness, extraversion, agreeableness and neuroticism.
