The Mediating Role Of Job Satisfaction In The Effect Of Employee Engagement And Motivation On Employee Performance At Negara General Hospital

Abstract

Employee performance is a key indicator of organizational success, particularly in hospitals, where the accuracy and speed of laboratory services directly support medical diagnosis and clinical decision-making. Signs of suboptimal employee engagement, work motivation, and job satisfaction in the hospital laboratory indicate the need to examine the factors that shape performance. This study aims to analyze the effect of employee engagement and motivation on employee performance, with job satisfaction as a mediating variable, among the laboratory employees of Negara General Hospital. This study employs a quantitative approach with a survey method. The population consists of all 40 employees of the Integrated Laboratory Unit, who were also taken as the sample using saturated sampling. Data were collected through a questionnaire and analyzed using path analysis in SPSS, while the mediating effect was tested using the Sobel test. The results indicate that employee engagement and motivation each have a positive and significant effect on job satisfaction and on employee performance. Job satisfaction has a positive and significant effect on employee performance. Job satisfaction mediates the effect of employee engagement on employee performance (Z = 3.42) and also mediates the effect of motivation on employee performance (Z = 1.97). The model explains 86.7% of the variation in employee performance. These findings suggest that hospital management can improve performance by strengthening employee engagement, sustaining motivation, and creating conditions that increase job satisfaction.
