Objective - This study aims to examine the role of coping optimism as a psychological mechanism linking self-efficacy and self-acceptance to adaptive performance among public sector employees. Specifically, the study investigates whether coping optimism functions as a full mediator in transforming personal psychological resources into adaptive workplace behavior.

Methodology/Technique - A quantitative cross-sectional survey was conducted involving 206 civil servants employed in regional government institutions. Data were collected using structured questionnaires and analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM) with bootstrapping procedures to assess the measurement and structural models.

Findings - The results indicate that self-efficacy and self-acceptance significantly enhance coping optimism. In turn, coping optimism has a significant positive effect on adaptive performance. The mediation analysis demonstrates that coping optimism fully mediates the relationships between self-efficacy, self-acceptance, and adaptive performance, suggesting that personal resources contribute to employee adaptability through optimistic coping processes. The model explains 52.5% of the variance in adaptive performance and demonstrates satisfactory predictive relevance.

Novelty - This study extends the adaptive performance literature by positioning coping optimism as a full mediating mechanism rather than merely an antecedent of adaptive performance. By integrating Social Cognitive Theory, Stress Appraisal Theory, Conservation of Resources Theory, and the Broaden-and-Build Theory, the study provides a comprehensive explanation of how personal psychological resources are transformed into adaptive workplace behavior within public sector organizations.
