The 16PF questionnaire (Cattell et al, 1970, 1993) is regarded as a 'comprehensive measure of normal range personality' (Cattell & Mead, 2008, p.135). The IPIP data base is in the open domain as are all measures/scales using them. No permission is needed to use any of these scales (https://ipip.ori.org/newPermission.htm). ////References: Cattell, R.B. Eber, H.W. and Tatsuoka, M.M.
