This initial effort to develop a measure of public service
motivation produced a multidimensional construct grounded in
public administration theory. Attraction to public policy making,
commitment to the public interest, compassion, and self-sacrifice
were confirmed as dimensions of public service motivation. At
the same time, the results indicate that public service motivation
is less complex than it is portrayed in the literature. Using
confirmatory factor analysis, the original six-dimension model
was pared to four dimensions.
