This study aimed to establish the best-fit structural model for the work performance (WP) of local government employees in Region XI, considering organizational citizenship behavior (OCB), emotional intelligence (EI), and public service motivation (PSM) as exogenous latent variables. A non-experimental quantitative research design was employed. Stratified random sampling selected 400 local government employees in Region XI to participate in the survey. Data analysis included descriptive statistics, correlation tests, multiple regression analysis, and Structural Equation Modeling (SEM). Results indicated that OCB and EI levels were high, whereas PSM and WP were rated very high. Correlation analysis revealed a significant positive relationship between exogenous and endogenous latent variables. Multiple regression analysis showed that EI and PSM significantly influenced WP, accounting for 65.6% of its variance. SEM confirmed that OCB, EI, and PSM are significant predictors of WP. Key observed variables included altruism, civic virtue, and courtesy for OCB; interpersonal sensitivity, motivation, and self-awareness for EI; compassion, commitment to the public interest, and attraction to policymaking for PSM; and task performance, contextual performance, and adaptive performance for WP. This study provides empirical evidence supporting the role of OCB, EI, and PSM in enhancing WP in the public sector. The findings offer insights for policymakers and organizational leaders to develop strategies that promote employee motivation, emotional intelligence training, and citizenship behaviors to improve public service performance.
