Tóm tắt	The Public Service Motivation Scale (PSMS), developed by Perry (1996) and refined by Kim et al. (2013), measures the intrinsic motivation of public sector employees to serve the public interest, contribute to civic good, feel compassion for others, and make self-sacrifices for collective benefit. Public service motivation (PSM) is a defining characteristic of effective public administration, predicting job satisfaction, organizational commitment, performance, and willingness to engage in prosocial behaviors. Essential for public sector recruitment, retention, and culture assessment in government agencies, tourism authorities, and civic institutions.	The Tourist Loyalty Scale (TLS) measures the extent to which visitors intend to return to a destination and recommend it to others, reflecting behavioral commitment and preference relative to competing destinations. Developed by Oppermann (2000) and refined across multiple tourism contexts, the TLS captures the ultimate outcome of satisfaction and destination image—willingness to invest time and money in repeat visitation and endorsement. As the true measure of competitive advantage in tourism, loyalty drives revenue stability, positive reputation, and ecosystem resilience.
