“…In line with this reasoning, Akkermans et al (2013) found a positive relationship between career competencies and self-efficacy, a concept generally considered to be a personal resource (e.g., Avey, Luthans, & Jensen, 2009;Luthans, Avey, Avolio, Norman, & Combs, 2006). Finally, Xanthopoulou, Bakker, Demerouti, and Schaufeli (2007) noted that personal resources are, to some extent, malleable and open to development. This characterization is similar to that of Akkermans et al (2013) who underlined that career competencies can be actively developed by individuals.…”
