Background: Morale is considered one of the most important determinants of institutional performance, especially in high-pressure environments such as the Palestinian security sector, which is influenced by complex political, security, and social conditions. The literature indicates that morale is composed of multiple elements shaped by various psychological and organizational variables. Objectives: The study aimed to test a proposed structural model that explains morale among employees in the Palestinian security sector through three variables: job satisfaction, job commitment, and national psychological hardiness. It also sought to identify the levels of these variables among security personnel and to determine the impact of selected demographic factors on morale. Method: The study utilized a descriptive, correlational, and predictive approach using structural equation modeling (SEM). A convenience sample of 189 military personnel from the Military Training Authority in Jericho was selected. Four scales were developed to measure morale, job satisfaction, job commitment, and national psychological hardiness. Their validity was confirmed using exploratory factor analysis, and they demonstrated high reliability coefficients. Results: The proposed structural model demonstrated validity and good fit after modification (AGFI = 0.997, CFI = 0.999, RMSEA = 0.001). Findings revealed that job satisfaction plays both direct and indirect positive roles in enhancing morale through two mediating variables: job commitment and national psychological hardiness. Results also indicated that years of service was the only demographic predictor of morale (β = 0.168, p < .05). Recommendations: The study recommends strengthening job satisfaction as the primary entry point and central driver for improving morale.
