All 45 items and how they're scored

1. Each answer is a number: Very untrue = 1, Somewhat untrue = 2, Neither true nor untrue = 3, Somewhat true = 4, Very true = 5.
2. Statements worded in the opposite direction (marked “reversed”) are scored 6 minus the answer, so “Very true” on “Am an honest person” counts as 1 toward manipulativeness.
3. A trait's score is the average of its statements, from 1.00 to 5.00. Every statement must be answered.
4. The label shown with a score is the answer option nearest that average (for example, 2.40 reads as “Somewhat untrue”).

There are no percentiles and no overall “difficulty” total. We didn't find a published reference group for these items that we could check, and adding the seven traits together would hide the differences that make the profile useful.

Statements are shown in a fixed, interleaved order (one from each trait in turn) so that items from the same scale aren't bunched together.

The statements are from seven scales of the CAT-PD static form (version 1.1), developed in a project funded by the National Institute of Mental Health (Simms et al., 2011) and published in the International Personality Item Pool. The item pool is in the public domain: permission is already granted to use its items for any purpose, commercial or non-commercial. Retrieved October 26, 2026.

The seven scales match the seven antagonism factors reported by (Sleep et al., 2021). That study analyzed items from several questionnaires; we don't know which of its items, if any, came from this exact form, so the match is by trait, not by item.

Our changes: Seven of the CAT-PD-SF scales selected; items interleaved; third-person wording for rating another person written by this site (not validated).
