As public service motivation research grows qualitatively and quantitatively, some scholars question its appropriateness for international applications. This essay sets out a strategy of convergence for international research and measurement approaches. Studies that assess commonalities in public service motivation content internationally are analyzed in order to develop a broader conceptual and more operational definition as well as consequently a more universal public service motivation construct. Public service motives, according to this review, are based on self-sacrifice and fall into three categories: instrumental, value-based, and identification. The dimensions of the public service motivation construct are refined along the lines of attraction to public participation, commitment to public values, compassion, and self-sacrifice. Researchers are urged to include all of its dimensions within their empirical studies to advance contemporary public service motivation studies.
