Research has suggested that coaches who possess a proactive personality have greater job performance. However, contextual factors that may serve as behaviors conditions have received insufficient attention in the research. Accordingly, this study proposed organizational citizenship behavior as a mediation in the positive relationship between proactive personality and job satisfaction. We have 91 paired, completed questionnaires which formed the basis of the data analysis. Our results suggest that significant correlation between proactive personality, job performance, and OCB. Additionally, OCB mediated between proactive personality and job performance. Our findings provide strong evidence that a high degree of proactive personality among sports coaches has a significant and crucial influence on their OCB and job performance.
