“…The choice of sex as a blocking variable was motivated by the extensive literature showing differences between male and female adolescents in career-related constructs (e.g., Betz & Fitzgerald, 1987;Farmer & Chung, 1995;Fouad & Spreda, 1995;Galotti, Kozberg, & Appleman, 1990;Kelly, 1993;Luzzo, 1995;Melamed, 1995;Patton & Creed, 2002;Tuck, Rolfe, & Adair, 1994).

Accordingly, the following two research questions were also investigated in the present study.…”
