Shows where you stand on 16 personality scales, such as warmth, assertiveness, anxiety, orderliness and distrust. Each scale is the average of about ten of your own answers, so you get a detailed profile instead of one score. It describes how you see yourself and is not a diagnosis.
This test uses the 16 preliminary scales of the International Personality Item Pool (IPIP), a public-domain collection of personality statements. The IPIP wrote them to measure constructs similar to those of Cattell's 16 Personality Factor Questionnaire (16PF; Conn and Rieke, 1994). There are 163 statements: 10 per scale and 13 for Intellect. Each answer scores 1 to 5, reverse-keyed statements are flipped, and the page shows the average of each scale. In the IPIP's sample of 501 adults the scales' alpha was .73 to .86. This is not the 16PF and not a replacement for it.
This is not a diagnosis
Personality traits are not good or bad, and a high or low score on a scale is not a disorder. The IPIP calls these scales preliminary, so read the result as a rough picture of how you see yourself today, not as an assessment for hiring or clinical decisions. Only a professional can assess difficulties, after a conversation.

Your score is calculated right in your browser. Your answers reach our server only if you ask for your result by email: we write the email and do not keep them.
Is this the 16PF?
No. The 16PF is a separate questionnaire with its own publisher. This page uses 16 preliminary scales from the public-domain International Personality Item Pool, written to measure similar constructs. In the IPIP's comparison table the matching scales correlated .51 to .77 with the 16PF scales (mean .66) in 501 adults. Sessio is not affiliated with the 16PF publisher, and this test does not replace it.
How is this different from a Big Five test?
A Big Five test describes five broad traits. This test splits personality into 16 narrower scales of about ten statements each, such as warmth, distrust, privacy and orderliness. For a broad first look at the five traits, take the short version: Big Five personality test
Can I compare my scores with other people?
Not directly. The IPIP pages for these scales give no norm tables or cut-offs, so this page shows only your own averages from 1 to 5. Take 3 as the middle of the answer scale, not as the typical person's score, compare the scales with each other, and retake the test later to see change.
