In this study, we sought to determine whether psychosocial development and self-efficacy of major changers differ from those classified as relatively stable. Participants completed the "Life-Skills Inventory-College" (Picklesimer, 1991) form to measure psychosocial development and the "General Self-efficacy" (Schwarzer & Jerusalem, 1995) scale to measure students' level of self-efficacy. Major changers reported a lower level of self-efficacy than relatively stable students, and relatively stable students scored higher on the self-perception measures of the "Problem-Solving/Decision-Making" subscale on the "Life-Skills Development Inventory" than did major changers.
