Objective : This study aimed to investigate the role of resilience and personality traits in the job performance of nurses working in hospitals in Astara city. Methods: This descriptive-analytical study adopted a correlational approach. The statistical population included all nurses employed in the medical centers of Astara city in 2024. Simple random sampling was used, with 179 nurses participating as the study sample. Data were collected using standard questionnaires and analyzed using Pearson correlation and multiple linear regression in SPSS version 26. The research instruments included the Nurse Team Resilience Scale, Big Five Inventory-2, and Individual Work Performance Questionnaire. Results: Resilience, situational awareness, adaptive capacity, and conscientiousness showed positive and significant correlations with job performance (p < 0.001), whereas key vulnerabilities exhibited a significant negative correlation (p < 0.001). Multiple linear regression indicated that the predictor variables significantly predicted job performance (p < 0.001). Situational awareness, environmental adaptation, and resilience were the strongest positive predictors, while key vulnerabilities had a significant negative effect (p < 0.001). Conclusion: The findings underscore the importance of psychological factors such as resilience, situational awareness, and psychological flexibility in enhancing nurses' job performance. Concurrently, the adverse impact of vulnerabilities highlights that reducing stressors and improving environmental conditions can play a key role in performance improvement .
