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.

Note. Values in brackets are corrected for unreliability. The values reported are from the Eugene-Springfield Community Sample; N=501.
