Background/Aims The relationship between job satisfaction and job performance has been well-established in healthcare research. This study aimed to measure job satisfaction and performance among staff working in emergency departments in Jordan, and to explore the association between these two variables, focusing on the different components of job satisfaction. Methods A cross-sectional design with a convenience sampling approach was used, recruiting 286 staff working across 11 emergency departments in Jordan. Participants completed a questionnaire comprising validated scales to measure job satisfaction and job performance. Descriptive statistics, Pearson correlation, Cronbach's alpha and multiple regression analysis were used, via the SPSS version 25, to explore the relationship between job performance and different components of job satisfaction. Results Mean scores on the job satisfaction and job performance scales indicated that participants were neither satisfied nor dissatisfied with their jobs, but had high perceived job performance levels. Multiple regression showed a significant positive relationship between three job satisfaction dimensions (colleagues' communication and relationship: B=0.16; physical environment and workplace safety: B=0.28; supervisor support: B=0.17) and perceived job performance (P<0.001). There was a small but insignificant association between job performance and the compensation and promotion dimension of job satisfaction (B=−0.05, P=0.192). Conclusions This study supports previous evidence indicating that job satisfaction is positively linked with job performance, although compensation and promotion may not be a strong predictor of job performance in an emergency department context. Overall, these findings highlight the importance of strategies to improve job satisfaction among healthcare professionals.
