Surveying Personality Traits The International Personality Item Pool, abbreviated IPIP, was originally conceptualized as a component of a project by Wim K. Hofstee at the University of Groningen in the Netherlands (International Personality Item Pool, n.d.). Hofstee and his fellow researchers sought to create items for personality based “on short, concrete behavioral phrases [which] would be less subject to idiosyncratic interpretation than ratings on relatively abstract trait adjectives” (International Personality Item Pool, n.d.). In three teams, individuals formatted items around the Big-Five personality factors, labeling one of the first models AB5C. (International Personality Item Pool, n.d.). Each

Donnellan, Oswald, Baird, and Lucas (2006) developed the Mini-IPIP, which is comprised of 20 items (p. 192). While some constraints of a study, such as the willingness of participants to answer questions in full, will never be completely eliminated, the Mini-IPIP was found to be an internally consistent measure of the Big Five factors (Donnellan, et al., 2006, p. 201). Thus, researchers in search of an abbreviated measurement of these personality factors should take advantage of the Mini-IPIP, “a very useful, efficient, and ultimately economical instrument given that it is in the public domain” (Donnellan et al, 2006, p. 201).
Surveying Leisure Time Activities Basic Interest Markers, or BIMs, were formulated by graduate psychology students using 28 definitions of interest conceived by Susan Day and James Rounds (Liao, Armstrong, & Rounds, 2008, p. 163). The students were instructed to craft 440 BIM items, which were administered through a survey to 216
