Study 1 examined the construct validity of the Strong Interest Inventory and the Study of Values for 695 intellectually talented 13-year-olds. Study 2 consisted of a generalization probe to 695 graduate students enrolled in select universities. This analysis manifested an impressive degree of adolescence-to-adult cross-validation. Well-known preference questionnaires appear to assess meaningful individual differences among intellectually talented young adolescents. How preference assessments may complement routine ability assessments of gifted adolescents and how counselors may use such information to encourage students to take a more active role in their personal development are discussed. The authors also present a methodological application, responsive to R. V. Dawis's (1992) concern about the amount of redundancy in psychological measuring tools.
