Proactivity, adaptability and boundaryless career attitudes: The mediating role of entrepreneurial alertness

• We examined entrepreneurialism and career attitudes and adaptability.
• Entrepreneurial alertness mediated proactive personality and boundaryless mindset.
• Entrepreneurial alertness mediated proactive personality and career adaptability.

We examined the role of entrepreneurialism in careers in the information society and global economy, bringing together key constructs in the fields of career studies and entrepreneurship. Specifically, our study involving a diverse group of 750 undergraduate students from Singapore showed that entrepreneurial alertness to opportunities partially mediates the relation of proactive personality to boundaryless career mindset and career adaptability, but not to self-directed or protean career attitudes. Findings are discussed in relation to the contribution of entrepreneurialism to careers research and the larger issues of workforce development.
