", "\nABSTRACT\nThis study examined the effectiveness of a career counselling training program designed to promote sustainable career development among university students. Grounded in a multidimensional view of sustainable careers, the intervention aimed to enhance key personal and contextual resources for sustainable career and its domains: health, happiness, productivity and social empowerment. A quasi‐experimental pre‐post design with follow‐up and a control group was used. Results demonstrated significant improvements across the resources supporting all four domains for participants in the training group. A significant multivariate Group × Time interaction confirmed the comprehensive and progressive gains associated with the intervention. Findings indicate that university‐based career counselling can effectively support student well‐being, integration and future‐oriented career planning, highlighting its value as a preventive and developmental approach for fostering sustainable career trajectories.\n"]
