Guided by the career construction theory (savickas, 2013), we view entrepreneurship as an adaptive vocational behavior driven by an individual’s self-regulatory capacity to thrive in a complex entrepreneurial career context. Our research model posited that individuals rely on their adaptive resources and entrepreneurial self-efficacy as they form entrepreneurial intentions. Career adaptability, as self-regulatory competencies, is further strengthened by prior exposure to family business. We collected data over three measurement periods from serbian business students (n. = 380) And validated the career adapt-abilities scale (caas). The moderated mediation model was supported and as predicted: (a) career adaptability was positively associated with entrepreneurial intentions and (b) the mediated relationship between career adaptability and entrepreneurial intentions via entrepreneurial self-efficacy was stronger for individuals with prior exposure to family business. In addition, we provide evidence for the psychometric properties of caas by examining its internal consistency, test-retest reliability, and factor structure. Taken together, our study offers the groundwork for understanding successful adaptation in the entrepreneurial career context and supports the cross-national measurement equivalence and utility of caas in a developing economy. 2014 Elsevier inc.
