This study investigated the structure of adult students' worries. Students (N = 309) enrolled in advanced undergraduate and graduate university courses were administered the Student Worry Scale. A factor analysis revealed three factors of student worries: worries about living conditions, esteem-related worries, and world-related worries. Worries varied somewhat by developmental level. Younger students were more worried about living conditions and how they were regarded, while older students were more worried about the state of the world. (Contains 1 table.)
