This study represents an important step in the development of a personality test battery to be used in the selection of officers recruited from outside sources in the Turkish Armed Forces (TAF). Prior to this study, following a personality-oriented job analysis, an initial test battery was developed and pilotted. Based on the pilot data, revisions were made in the initial test battery, resulting in a four-factor model of personality. In the present study, the revised battery was administered to a large group of officers (N = 698), representing different forces and ranks in the TAF. A series of confirmatory factor analyses was performed using LISREL 8.30 (Joreskog and Sorbom, 1996) to test the four-factor, 19-subdimension model of personality. As indexed by a variety of fit indices, the model suggested a good fit to data, providing evidence for the construct validity of the battery develepod. Steps following the present analyses are briefly discussed.
