TY - EJOU AU - Guo, Xin TI - Core self-evaluations (CSE) and career success: Task performance and leader-member exchange (LMX) mediation effects T2 - Journal of Psychology in Africa PY - 2025 VL - 35 IS - 6 SN - 1815-5626 AB - Core Self-Evaluations are linked to career success, yet the person-environment factor mechanisms underlying this relationship remain unclear. This meta-analysis (N = 135,809) synthesized the evidence on whether person task performance and LMX environment mediate the effects of CSE on career success both objective (salary) and subjective (job satisfaction) indicators. This study employed meta-analytic structural equation modeling (MASEM) to test direct and indirect pathways. Results integrating tournament theory and LMX theory show that CSE positively relates to task performance and LMX, both of which in turn relate to salary and job satisfaction. A significant sequential mediation pathway was also supported (CSE → LMX → task performance → career success). These findings highlight the dual importance of individual performance and social exchange with leaders in achieving career success and advance theory by linking tournament and LMX perspectives.
