Penelitian ini adalah penelitian kuantitatif dengan desain penelitian non-eksperimental. Teknik sampling yang digunakan adalah purposive sampling. Partisipan dalam penelitian ini adalah mahasiswa program sarjana (N=256) dari berbagai universitas di Jabodetabek yang sedang menempuh semester 6 atau lebih. Career Decision Self-Efficacy Scale – Short Form (CDSE-SF), Career Adapt-Abilities Scale (CAAS), Parental Career-Related Behavior Scale (PCB-S) menjadi alat ukur dalam penelitian ini. Pengolahan data dilakukan menggunakan Pearson Correlation dan macro PROCESS dari Hayes.

The transition from college to the workforce is a challenging period for senior year college students. These transitional periods are often colored with a variety of uncertainties and changes, thus demanding that individuals have good adaptability. This study aims to examine the role of career decision self-efficacy in mediating the relationship between parental career-related behavior and career adaptability among senior year college students. This is a quantitative study with a non-experimental research design. Purposive sampling was used to collect data from 256 undergraduate students from various universities in the Jabodetabek area who were in their 6th semester or higher. The research instruments used were the Career Decision Self-Efficacy Scale – Short Form (CDSE-SF), Career Adapt-Abilities Scale (CAAS), and Parental Career-Related Behavior Scale (PCB-S). Data analysis was conducted using Pearson Correlation and Hayes' macro PROCESS. The results of this study showed that career decision self-efficacy can be a partial mediator in the relationship between support parental career-related behavior and career adaptability, and a full mediator in the relationship between interference and lack of engagement parental career-related behavior and career adaptability. This research has implications that improved career decision self-efficacy and support parental career related behavior can improve the career adaptability of senior year college students. This study provides benefits for career development in higher education, students, and parents.
