The general purpose of this research is to test the applicability of the career construction model with the structural equation model in explaining the relationships between adaptive readiness (personality traits and hope), adaptability resources (career adaptability) and adapting responses (career decision-making self-efficacy). This research was carried out with the participation of 296 emerging adulthood [Ageranj = 19-26, AgeMean =21.46, AgeSd = 1.29] in different departments of the education faculty of a public university in Turkey. Data was gathered through the Dispositional Hope Scale, The Big Five Inventory, Career Adaptabilities Scale and Career Decision Self-Efficacy Scale. A two-stage structural equation model based on the maximum likelihood estimation was used in data analysis. The mediation test in this research was interpreted according to the stages of Baron and Kenny. The structural equation model tested in the research findings was confirmed.
