Research on the processes of change in career development has focused on developmental stages rather than processes. This manuscript reports on the development and validation of the stages of change-career development scale, adapted from McConnaughy, Prochaska, & Velicer (1983) measure of stages of change in psychotherapy. Data from 875 postsecondary students were analyzed using exploratory and confirmatory factor analysis, resulting in a 15-item measure with five factors. Convergent and divergent validity was demonstrated, suggesting that this scale has the potential to explicate the process of change in ways that will be useful to research and practice.
