I just ran out of a large shipment of NEO-FFI booklets, so I went to order more from PARinc. This shipment has lasted since 2014.
It seems that the original version of the NEO-FFI that I was using (from 2003) is now out of print and has been updated with the NEO-FFI-3.
Is anyone aware of the differences between the two versions? I can't really find much information on the change between the two, so I assume they're not significantly different?
NEO Five-Factor Inventory (NEO-FFI) is a shortened version of the NEO Personality Inventory (NEO-PI) now in its 3rd edition (NEO-PI-3). Both inventories were first published in 1985 and now the NEO-FFI is also in its 3rd edition as of 2005 (NEO-FFI-3).
NEO-FFI-3 measures the "Big 5" personality traits (Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness), comprises 60 items and is designed to take 10 to 15 minutes to complete; by contrast, the NEO-PI-3 takes 45 to 60 minutes to complete.
Both NEO-PI and NEO-FFI were originally developed for use with adult men and women without overt psychopathy.
The latest revision of the NEO-FFI involved the replacement of 15 of the 60 items to improve readability and psychometric properties. The revised edition is now thought to be more suitable for younger individuals and is also thought to have a stronger factor structure and increased reliability (McCrae & Costa, 2010).
