The current study seeks to shed light on social-cognitive resources that mitigate master students' experience of dysfunctional career-related worry before graduation. Based on the career self-management model (CSM; Lent & Brown, 2013), we investigate concurrent and time-lagged direct and mediated relationships between career planning, career-related self-efficacy, and career-related worry among a sample of 482 students shortly before graduation. Using data collected at three time points, a negative relationship was found between career planning (T1) and career-related worry (T3) via career-related self-efficacy (T2). Our findings shed light on the role of career planning and career-related self-efficacy as malleable social-cognitive resources that diminish dysfunctional thinking before graduation in sequential order. These findings imply that career planning and career-related self-efficacy are relevant predictors of affective states and can be incorporated into the CSM.
