IPIP equivalent to Cattell's 16 Personality Factor, 16PF
Online version of the IPIP equivalent to Cattel's 16PF. The Sixteen Personality Factor Questionnaire (16PF) is a self-report personality test developed over several decades of empirical research by Raymond B. Cattell, Maurice Tatsuoka and Herbert Eber. The 16PF provides a measure of normal personality in 16 primary trait constructs.
Please note: this is NOT the actual Cattell's 16PF questionnaire, but the public domain IPIP Scales, measuring similar constructs. The scores you'll get are not a replacement, they will only correlate with the scores you would actually obtain if you took a real 16PF and are probably much less valid.
