Many changes in the socioeconomic scenario led to the emergence of different models of career guidance, among which the protean career stands out. This model works with the prospect of a career that is self-directed and aligned with personal values, with important propositions for both professionals and students entering the work market. In the Brazilian scenario, however, there is a lack of appropriate measures to evaluate protean aspects among college students without work experience. Thus, the present study aimed at adapting and validating the attitudes towards the Protean Career Scale to this population. The sample consisted of 902 students aging from 18 to 30 years old (M = 22.52; SD = 6.53) attending 34 different undergraduate courses. Exploratory and confirmatory analysis attested the two-dimensional nature of the scale structure. The reliability indexes were satisfactory: over .65. The correlation between the protean models and factors such as personality, values, and locus of control provided adequate evidence of the measure’s predictive validity (p < .05).

This research is aimed at analyzing the relationship between the underlying dimensions of boundaryless (boundaryless mindset and organizational mobility preference) and protean (self-directed and values-driven) career attitudes and subjective career success, within today's complex and dynamic organizational context in which careers are unfolding. Drawing on a sample of 150 Spanish professionals from the Catalonia region, which enabled hypotheses testing by means of hierarchical regression analysis, the research results suggest that self-direction in managing one's career and vocational development is instrumental in achieving subjective career success. Organizational mobility preference was found to be negatively associated with individuals' perceptions of the success achieved in their careers. Furthermore, the study suggests some future research lines that could draw more light upon the hypothesized relationships.
