Examined conceptions of adulthood among adolescents, emerging adults, and parents of adolescents in Israel. Found widespread support for individualistic criteria for adulthood, such as accepting responsibility for one's actions, deciding on one's own beliefs and values, and becoming financially independent. Found considerable support for collectivist-oriented criteria in the domains of responsible norm-abiding behavior and role transitions. Identified age, gender, and Israeli-U.S. differences. (KB)
