The Career Decision Self-Efficacy Scale (CDSE) measures an individual's degree of belief that he/she can successfully complete tasks necessary to making significant career decisions. The CDSE consists of five subscales measuring the five Career Choice Competencies of John O. Crites' Theory of Career Maturity. The CDSE is available in both a 50-item form and a 25-item short form. It is strongly linked to positive educational and career decisional outcomes.
