We analyzed the impact of a self-assessment instrument on the self-efficacy of those deciding on majors in a university setting. Using a pre- and post-test methodology, we employed "Career Cruising" to measure career decision-making self-efficacy. Participants completed the "Career Decision Self-Efficacy-Short Form" (CDSE-SF) with dependent variables of academic advising and the levels of self-efficacy among the CDSE-SF five subscales: Accurate Self-Appraisal, Gathering Occupational Information, Goal Selection, Planning for the Future, and Problem Solving. The data were subjected to paired and independent t tests to measure any differences in mean scores. The results indicated a slight increase in career self-efficacy for students who participated in both Career Cruising and academic advising.
