The factor structure of Holland's hexagonal model as shown in the Self-Directed Search (SDS) has received extensive attention across the world. The goal in creating the SDS was to equip guidance counselors and services with information about adults' personality types, interests, preferences, and career options. More precisely, the SDS items assess personality types and link them to other measures or instructional repositories containing tools for educational and vocational planning. The SDS has been translated into 25 languages, adapted for use in many cultures, and supported in many countries such as Australia, Africa, Europe, and Asia, but not in the Kingdom of Saudi Arabia (KSA). This study evaluated the application of the SDS to Saudi students, and examined the newly-translated inventory's internal structure and consistency in the KSA and Arabic-speaking cultural context. The Arabic version of the SDS-Form R, 5th Edition was administered to first-year students (N = 1,090) at King Abdul Aziz University (KAU), Jeddah, KSA. The main objective was to evaluate the validity and the reliability of the Arabic Version of the SDS-Form R, 5th Edition. The secondary objective was to examine the differences on the SDS responses between male (n = 457) and female (n = 633) students and between students in the Scientific track (n = 603) and the Administrative and Humanitarian track (n = 487) and to determine the equivalence of both genders and tracks in fitting the data to the Holland model. Evidence regarding the application of the SDS in the Saudi population was obtained. [The dissertation citations contained here are published with the permission of ProQuest LLC.
