Note. All analyses are based on the responses of 501 adult participants from the Eugene-Springfield Community Sample. [Values in brackets are the correlations between the corresponding CPI and IPIP scales when corrected for the scale reliabilities.]

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.
