Scale construction of a "Big Five" personality inventory

Abstract

The purpose of this study was to construct a Big-Five personality inventory, As a pretes t,95 items were administered to 236 students, along with Goldberg' sbipola rBig-Five marker inventory and the MINI Personali tIynventor )iT.he markers proved to be a good criterien fer the fiv efacto rmodel {FFM}, and 69 jtems were selected. In the main study, 496 students responded to 300 items ,includin gthe 69 pretest and the 43 MINI items that correlated highly with the markers, together with the Big-Five marker and the MINI inventori esU.sing MINI scores as criteria, those with poor insigh twere dropped ,keeping 443 for fttrth earnalyses, Firs tw,ith the Big-Five markers as criteria, 150 items were chosen. Then, with group princip acoLmponent analysis, 60 items were selected, and principa lfacte ranalysis with orthomax and fact oprarsimony criteria was applied, yielding a simple five-fact ostrructure. Finall yC,orrec Atttitudes items of the MINL Inventor ywere added to make 70 items ,which were reordered for a fina lversion, The correlations between the new scales and the Big-Five markers were between .510 and ,774 ,and one-week test-retest reliability with 227 students ranged between .853 and .953, $howing high reliability and validity.
