We tested the social cognitive model of choice (Lent, Brown, & Hackett, 1994) using a longitudinal design. Participants were 116 students taking beginning engineering courses at two historically Black universities. They completed measures of self-efficacy, outcome expectations, interests, goals, and environmental supports and barriers near the end of two consecutive semesters. Path analyses indicated overall support for the choice model and, in particular, suggested that self-efficacy served as a temporal precursor of outcome expectations, interests, goals, and supports. Interests and self-efficacy were found to be reciprocally related but, contrary to expectations, supports and barriers did not account for unique variance in self-efficacy. Implications for future research on the choice model are discussed. (Contains 1 figure and 4 tables.)
