Two sides of the career resources coin: Career adaptability resources and the impostor phenomenon

•Postulates a model based on career construction theory (CCT) for the impostor phenomenon (IP).•Examines the direct effects of adaptive readiness on adapting responses.•Identifies specific indirect effects of career adaptability resources and the IP.•Compares simple and multiple parallel mediation analyses.•Offers theoretical and practical implication regarding CCT and the IP.

Considering the impostor phenomenon (IP) as an important psychological construct in the context of career development requires a theoretical grounding. Using the career construction model of adaptation as a guiding framework, we investigated how the IP is related to adaptive readiness (represented by core self-evaluations), career adaptability resources, and adapting responses, namely, career planning, career decision-making difficulties, career exploration, and occupational self-efficacy. We used parallel multiple mediation modeling to investigate specific indirect effects through concern, control, curiosity, confidence, and the IP. We conducted an online study with 289 university students. Results indicated a positive effect of core self-evaluations on career planning, career exploration, and occupational self-efficacy and a negative effect on career decision-making difficulties through adaptability resources. The IP emerged as a “maladaptability” resource: That is, it might be a hindrance to adaptive coping and behavior and consequently promote maladaptive coping and behavior by decreasing career planning and occupational self-efficacy and increasing career decision-making difficulties. Supplementary negative effects of the IP on adaptability resources are discussed.
