Note.  [Values in brackets are correlations corrected for unreliability; these may be underestimates, given that the reliabilities of the factor markers were assumed to be the same as those of their corresponding IPIP scales.]

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.
