The structural validity of the Personal Globe Inventory-Short (PGI-S: Tracey in J Vocat Behavi 76:1-15, 2010) was examined in a Turkish sample of high school and university students. The PGI-S measures eight basic interest scales, Holland's ("Making vocational choice," Prentice-Hall, Englewood Cliffs, 1997) six types, Prediger's ("J Vocat Behav" 21:259-287, 1981) people/things, data/ideas dimensions, and prestige. After adapting the original PGI-S items into Turkish (PGI-S-T), the inventory was administered to high school students (N = 605) and university students (N = 359). The fit of Holland's RIASEC and the PGI eight type model were examined separately using the randomization test of hypothesized order relations. Results indicated a strong fit for both the eight type and the RIASEC model. Expected significant differences were found between PGI-S-T subscales across gender and age. The results support the structural validity of the adapted PGI-S-T in a Turkish sample.
