The purpose of this study was to construct
a Big-Five personality inventory. As a pretest,
95 items were administered to 236 students,
along with Goldberg's bipolar Big-Five marker
inventory and the MINI Personality Inventory.
The markers proved to be a good criterion
for the five factor model (FFM), and 69 items
were selected. In the main study, 496 students
responded to 300 items, including the 69
pretest and the 43 MINI items that correlated
highly with the markers, together with the
Big-Five marker and the MINI inventories.
Using MINI scores as criteria, those with
poor insight were dropped, keeping 443 for
further analyses. First, with the Big-Five
markers as criteria, 150 items were chosen.
Then, with group principal component analysis,
60 items w ere selected, and principal factor
analysis with orthomax and factor parsimony
criteria was applied, yielding a simple five-factor
structure. Finally, Correct Attitudes items
of the MINI Inventory were added to make
70 items, which were reordered for a final
version. 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, showing high reliability and validity.
Key words: five factor model, the MINI
Personality Inventory, Goldberg's Big-Five
markers, test-retest reliability, group principal
factor analysis
