The original Career Interest Inventory (CII) included four parts: vocational activities, leisure activities, curriculums, and vocational titles. The samples for the study were 304 college students and 91 high school students. Sincer, the results of item analysis in the leisure activities part was not satisfctory, the other three parts (180 items ) were then adapted as formal scales. Reliability analysis indicated that the inventory has resonably high internal consistency and stability. Meanwhile, the results of convergent - diseriminant validity and factor analysis reflected adequate Holland constructs (R-I-A-S-E-C) in the scales.
