Further, the current study aimed at investigating relationship between each with decision-making, and  detect  possibility of the big five personality factors to predict self-efficacy, and the possibility of both to predict decision-making among female schools' principals in Riyadh City. The study sample consisted of (N= 220) female principals of public schools in Riyadh City with a percentage of (39%) of the study population. In order to collect data and test the study variables several tools were used. These were; Demographic Information Form prepared by the researcher, Self-efficacy Scale excerpt from (Hisham Abdullah, Essam El Akkad, 2008), the Big Five Personality Factors Scale prepared by Costa and MacCrae (1992) and the Decision-making Scale that used by each of Abdoun (d. v) and Subaie (2001).
