Note. Values in brackets are corrected for unreliability. The values reported are from the Eugene-Springfield Community Sample; N=757.

Maples, J. L., Guan, L., Carter, N. T., & Miller, J. D. (2014). A test of the International Personality Item Pool representation of the revised NEO Personality Inventory and development of a 120-item IPIP-based measure of the Five-Factor Model. Psychological Assessment, 26, 1070-1084.

Note. The numbers under the "+ -" heading indicate the number of positively and negatively items in the scale. So, for example, "5+3=8" indicates that there are 5 positively keyed items and 3 negatively keyed items, for 8 total items.
