BACKGROUND INFO 	
___________________________________________________________________________________________________________________	

This script implements Millisecond's computerized version of the MiniIPIP, a short measure of the 
Big Five factors of personality introduced by Donnellan et al (2006). The MiniIPIP is a 20 question survey using 
a subset of the IPIP  (International Personality Item Pool) items used by the 50-item IPIP representation 
of the Big-Five lexical markers (Goldberg, 1992).

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).
